Hey leute, ich überlege mir bald einen neuen pc zu bauen, mit amd phenom ii x4 955. allerdings würde ich diesen gerne uach höher übertakten. Even though it is a lot better than its ancestors, it still has a long way to go. Changing the CPU-NB frequency to lower or higher settings may help stabilize the OC. AW: Welchen Kühler für AMD Phenom II X4 955 BE Das selbe hier, Scythe Mugen 2, bietet eins der besten P/L-Verhältnisse Mein 940er klettert auf 55°C bei 3,7 Ghz, unter nem Noctua NH-U12P. You will also need wPrime version 1.55 and the latest version of CPU-Z. With the Phenom II, a new era of overclocking was created. The reason behind this is due to the IMC limitations. Along with the formula, Table 4 shows what voltage you may need using ‘Y’ CPU-NB Multiplier. On a side note, I did mention that the HTT will be used a lot more with Thuban. With HT 3.0 technology the AMD Phenom II X4 955 Quad-Core processor enjoys 3200MHz system bus speeds. I do not suggest using it for 24/7 overclocking though. Although the Thuban and the Deneb are sister and brother in nature, they tend to behave differently when overclocking. This CPU has a stock speed of 2.8 GHz. You guys really reduced it from ∞ to 3? It is always important to know the stock settings for your particular CPU. Now that you understand how to overclock your CPU, let’s look at the second part of the CPU. The Deneb is much hungrier when it comes to voltages and it does not cope well when the core temperature is anywhere near 55 C. The Thuban is much more gentler, and allows higher clocked cores without the need for high voltages. Since we have seen the tock, we now expect even further refinement. Normalerweise hab ich bei meinem Phenom einfach denn Multi angehoben und hab ihn so ein klein wenig Übertaktet. You should first try increasing the voltage before increasing the frequency. For those interested, more complete processor specifications can be referenced in the AMD Power and Thermal Data Sheet. Repeat wPrime test, then repeat CPU speed increase until either one of two things happen; either the system becomes unstable due to lack of voltage, or the CPU will get too hot. If you push something too much, you will have to increase the voltage for that section of the CPU. The Phenom II has a maximum temperature of 55C. Now let’s say you have a 266 FSB. Just to give an idea of how much was trimmed down. The first one gives information regarding what may cause a crash when overclocking. If you have that wall controlled, your overclocking experience will be a better experience. You should know how high you will want to push the voltage, but a reasonable guideline is to not go beyond 1.55V on air cooling. I mentioned in the Memory section that the Memory has limitations due to the CPU-NB. Then, when you switch from automatic to manual mode, you do not start off too low or too high with your overclocking. This can be a long process so take your time in trying to balance it all. But for a CPU that has a core speed of 2.8 GHz that is increased to 3.0 GHz either technique will create a faster CPU: by increasing the FSB or the multiplier or both. If not, then why every other reviewieng site shows AMD PHENOM 2 X4 955 BE defeating Core i7 940 on evey computing prospects. Prime 95: Use this tool to check full stability. With this ‘Y’ voltage at ‘X’ speed, you have been able to see if it is stable under Prime95 with ‘C’ CPU-NB settings and ‘B’ HTT settings (where ‘C’ also includes CPU-NB voltage). AMD Phenom II X4 955 vs Intel Celeron G530: 4. 108. In order to overclock your computer, most people would simply increase the FSB because the CPU is typically multiplier locked. Wie kann ich das Gehäuse verändern? Note that these are calculated speeds, and should not be taken to word. This guide will use some basic terms that you may not be familiar with. Listed below are the typical stock voltages of a Phenom II. Make sure to try a variety of different settings until you feel comfortable. Your email address will not be published. If you go above this, you may want to lower the HTT back down between 2200 – 2400 MHz. The Voltage issue is simple, increase voltage. If all has gone well, you should have found a high overclock that is technically your max with the variables set by the theoretical max found by the AOD testing. It tends to work better. In most cases your theoretical max speeds that you have found will not work under the Prime95 test, you may have to increase the CPU voltage, or find a balance with the CPU-NB and HTT. For most people, they want to use the overclock settings they obtained 24/7. Intel Core i7 920. Make sure you have AOD open and CPU-Z open at the same time. The ROG STRIX RTX 2060 OC is currently priced at $399 which is only $50 over the lowest priced model over at Newegg.com, let’s take a dive into this card and see what that $50 is going to get us. The AMD Phenom II X4 955 is a quad-core processor based on the K10 micro-architecture. The six timings that you will tweak are: Cas Latency (CL), RAS# to CAS# Delay (tRCD), RAS# Precharge (tRP), Cycle Time (tRAS), Bank Cycle Time (tRC), and Command Rate (CR). As you continue to increase your CPU speed, make sure to watch the CPU temperature. In most cases, you will not need to exceed 2.4v on DDR2, and no more than 2.1v on DDR3. All of the settings that I refer to will be located in your motherboard BIOS. By all means you should think about looking at the CPU-NB each and every time when trying to push for a different CPU Frequency. For this next example I will take a Phenom II 940 BE CPU and overclock it. It often creates a much more stable environment if you do this. Yes that is correct, the CPU-NB also creates heat on the die. Intel Celeron N2815 vs AMD Phenom II X4 955: 2. Prerequisites explain basic details to understand the guide. The first thing you can do with your RAM is to continue to keep it at stock or close to stock. B CPU: AMD Phenom X4 II 955BE @ 3,62 Ghz Mainboard: Gigabyte GA970D3 RAM:... Dieses Thema im Forum "Prozessoren" wurde erstellt von Go4Nvidia, 20. 118. Each manufacturer’s motherboard BIOS is unique, referring to the same settings with different terminology and layout. For the first time, liquid helium (boiling point: -269 C) was brought into the field of overclocking. Let us take a step back and look at what you have done so far. If that does not work then you have to bring things back down, and figure out how to create a faster overclock at slower speeds. First, just try increasing the multiplier. 113. I personally love doing this in my spare time. Deneb was the first Phenom II core released. After a long time of re-writing and waiting on AMD to push out all of their CPUs, I want to share with the community the final guide for the Phenom II CPUs. If your CPU is too fast and your CPU-NB is too slow, you will create instability. For now, the default timings of your RAM should prove to be the best for overclocking. Mit dem AMD Phenom II X4 945 bekommen Sie einen 3-GHz-Quad-Core für günstige 150 Euro. 4,1 GHz konnte man noch Cinebench rennen lassen: For the most part you will not have to do much with the HTT but sometimes lowering it below stock will get you to the CPU speed you want. To those who do have to use this process, feel lucky. It was genuinely very helpful. The original Guide that I created is about 50 pages long. First thing to do is to find the limit to your FSB . Each motherboard maker has their own way of making their BIOS. Check out the Overclockers Benching Team to learn more about how to overclock your Phenom II! If this is not the case, follow BSOD instructions. For my first example I will use the Phenom II 810. To all those that were expecting a section called “The Heat Wall” here it is in simple form. In this section I will teach you overclocking basics for the Phenom II. If your CPU-NB is too fast, your memory may become unstable, or your CPU may become unstable. One thing you should notice right away is that the CPU-NB and the HTT are using the same multipliers at stock settings. This will serve as a very useful tool as you overclock your Phenom II. This method only works with Phenom II BE chips though. Before We Overclock details the 3 major subsystems which are key to overclocking this family of processors and is helpful for understanding how things work together. If you are having trouble with your overclocked CPU, instead of increasing the CPU-NB try to bring it down. This section is intended for those that do not have a B.E. It has been a very long road with this guide. These can potentially even lower the voltage used when in idle mode. There are many benefits to this and they will be discussed in detail later in this section. Let me put this in practice, before you start to debate my theorem. The CPU-NB is the section of the CPU that controls the L3 Cache, IMC and the HTT. Here are the most common terms that I will be referring to. With the 810, I can only increase the FSB in order to overclock the CPU itself. Ersteller des Themas Gikon; Erstellungsdatum 23. These CPUs have an unlocked multiplier and will allow the user to just increase the multiplier of the cores, thus increasing the speed of the CPU. Depending on your PSU (Power Supply), cooling, and hundreds of other factors, if you try to continuously push your CPU over the max, you could end up harming it. Your first option is to raise the CPU Voltage. As you can see with Table 3, these are the supposed frequencies of your CPU-NB at X CPU frequency. You guys have it the easiest, but this time around I’m not going to just tell you what you need to do in order to achieve a high overclock. The idea behind the formula is a rough estimate of what you should be at with ‘X’ CPU Frequency. For example if my stock speed is 3.0 GHz which is 15 multi and 200 FSB, when I get to 210 FSB my multi should be 14.5. The second section is catered to Thuban overclockers. Once it seems that your System will not crash, open up wPrime v1.55 and set the thread count to 6 under advanced settings. Mostly because it is usually the culprit of bad overclocks. After the rather disappointing Phenom was on the market for a year, the Phenom II brought AMD out of a huge hole as although the Phenom II did not compete on par with Intel in the benchmarking world, it did bring to the market a low cost CPU that was just as good if not better when it came to gaming. As a second side note, some of the newer boards that use the 8-series chips now have a feature called LLC or Load-Line Calibration. Open up AOD; This tool is designed to do exactly what I am showing you. To be blunt, the Phenom II CPU-NB is not the best. For the first wall, let us find your max core wall. The recommended voltage for 24/7 usage is 1.40-1.45 v. If you run into a situation in which wPrime throws an error, this is considered a theoretical max as well. The Third section “Crash *Computer Explosions*” has two main sections. AMD Virtualization can enable client computers to seamlessly support multiple operating environments. The FSB always has a stock frequency of 200 MHz. Most of the time, you will be required to have a pretty high voltage on the CPU-NB with a low frequency in order to keep your CPU stable. The reason for the memory limitations is mostly based on how the CPU-NB was built by AMD. So you put alink there for someone to have to type it in instead of a direct link? 200 * 15 = 3000 MHz Core Speed, Overclock using FSB: AMD Phenom II X4 945 übertakten. Note, that “The Heat Wall” will also appear in places you never would expect. The other way is to increase the FSB. ): Hey Leute hab nen kleines Prob beim Übertakten. Use for 12+ hours to learn if settings are fully stable. So let us look at how the FSB and Multiplier can be used to overclock the CPU. With  the speeds increasing for memory, it is normal that latency increases for stability purposes. After a year of the very successful Deneb series Phenom II, Thuban was released. It only cares about how much voltage you are giving it, and how cold it is. • Freeze Ups: This may be caused by overheating of the CPU or could be a precursor to BSOD. For example, I will calculate 1600 RAM, using standard AMD Settings which is a 200 FSB frequency setting. 45,2. Please make sure to research this before taking my word though. This is so because we want to force the CPU to stay at stock speeds. But the general idea is that the FSB of your CPU will determine the speed of your RAM. You are close to damaging the CPU if you go any further. AMD Phenom II X4 940 Black Edition. With these “Theoretical Maxes”, you can now find the max stable overclock with your defined CPU voltage. The timings are most commonly represented as CL-tRCD-tRP-tRAS. If you are anywhere near this sweet spot, OC settings will start to become unstable. Nach unserem AMD Phenom II X4 955 BE Testbericht konnten wir sehen, dass es sich hier um eine sehr interessante CPU handelt. This will be talked about in more depth under the CPU/NorthBridge section. Deneb was the first Phenom II core released. Of course, as you increase the CPU-NB frequency, you have to increase the CPU-NB voltage. The third option that you may want to try is messing with your RAM. Table 1 shows an example of some common ratios. This seldom works, but has proven to work in some situations. The HTT and a couple of other things are what make up the CPU-NB but to make things more straightforward, I will talk as if the CPU-NB and the HTT are two different entities. Aber der TE hat leider eine C2 Revision, die wollten meistens nicht ganz so viel^^, Powered by vBulletin® Version 3.8.10 (Deutsch), Copyright © 1999-2015 TweakPC, Alle Rechte vorbehalten, all rights reserved, http://www0.xup.in/exec/ximg.php?fid=80637590, http://www0.xup.in/exec/ximg.php?fid=14472317, http://www0.xup.in/exec/ximg.php?fid=30878697, http://img.tweakpc.de/images/2015/10...pc2h3xy.th.png, http://img.tweakpc.de/images/2015/10...eakcchi.th.jpg, http://www.tweakpc.de/forum/tutorial...rclocking.html, theon`s CPU Frequency score: 6611.88 mhz with a Phenom II X4 965 BE, Jemanden per E-Mail auf dieses Thema hinweisen. How you should approach the CPU-NB is pretty simple: resort to changing the CPU-NB as a last step. AMD Phenom II X3 720 Black Edition. Queue the 7th generation of Intel CPUs, dubbed, Kaby Lake (pronounced KAY-BEE). Read More. You can find it here onAMD’s website . This can end up causing BSODs (Blue Screen of Death) or Freeze ups. For this you will need to get AMD OverDrive (AOD). The cores are connected by the FSB or HT Link (HTL) – even the CPU-NB runs on it. No matter what you do, you will not be able to get around this wall. This will surely become one of the staple go-to guides for AMD overclocking. 40,9. Ich habe Prime 95 ca. If your goal is to make your CPU stable, you NEED to lower the settings to have the CPU LOAD temp at a max of 55 °C. • BSODS: This is caused by memory instability. NOTE: You can look up your default timing by using a free program called CPU-Z and going to the SPD Tab. Intel Burn In: A tool that is recommended by most to test for stability as well. In some cases you will find that 7-9-7-15-30, or something similar, will be the best for speed and stability. If on, the voltage will have a bit of bigger area of which it can operate. AMD Phenom II X4 955 vs Intel Pentium D1508: 5. With these new buffs the Phenom II got a new boost in the CPU market. Übertakten eines AMD Phenom II X6 1090T: SKy89: Overclocking - Übertakten: 7: 18.06.2015 20:12: Phenom II X6 1055T Übertakten auf 4 Ghz: Chabrol: Overclocking - Übertakten: 4: 01.07.2013 07:31 [News] MSI Unlock CPU Core: Aus Phenom II X4 wird Phenom II X6 geht auch mit MSI: TweakPC Newsbot: News: 1: 19.04.2010 19:30 You can do a couple of things with your RAM. Nice work :thup: He already listed they were guidelines, and if further information is needed it can be referenced from the document he linked to. The guide will work with all Deneb, Heka, Callisto, and Thuban CPUs. Phenom II X4 955 BE übertakten. This tends to be a lot of fun for most people. Start pushing the FSB by a factor of 10, and then by a factor of 5. With that in mind let us get started. Phenom II. 97. What needs to be stored will go through this guy first. Before I let you go, I will end it all with a nice wrap up. Save my name, email, and website in this browser for the next time I comment. For example, if your system is running at 14C load temp, you may only see a maximum OC of 4.2 GHz or something similar. Soon after, the 720 and 500 came out onto the field, bringing the possibility of core unlocking with them. You can try to increase your RAM to a higher ratio, and using what you learned about your RAM back in the RAM section, increase the timings to work with that ratio. On some instances it has bashed on Core i7 965 extreme. One important thing to also note and always remember is that the HTT speed can never go higher than the CPU-NB speed. Just know that modifying the FSB will also affect things other than the CPU core speed. Most of the time, this will work. Most of you that have been around the forums know about “Dolk’s guide” if you have ever wandered into the AMD section. 41,4. Now you can move on to seeing how far you can push your CPU. In other terms, FSB * CPU Multiplier = Speed of CPU. Although, the reason behind that error could be caused by RAM or CPU-NB, but for now we will consider this as a theoretical max. I remember reading this when the 720's first came out. A good place to confirm stock specifications is AMD’s desktop processor product list. In here everything is still connected by the FSB of the CPU, and each part has its own speed. To make sure these settings are stable you should use the tools below: On the other hand some of you just want to score some great scores using benchmarks. Taking a structured approach, this guide talks about each individual part of the system that you will need to overclock. What really separates the two in the overclocking world is the balance between the four parameters: CPU Cores, CPU-NB, HTT, and RAM. You finally get to overclock your CPU [rejoice]. Deneb allows you to effectively ignore the CPU-NB or the HTT. RAM should be at its default SPD settings as well. Nicht nur die Performance... Klicke in dieses Feld, um es in vollständiger Größe anzuzeigen. AMD hat aus Kostengründen nicht auf LGA1366 Ebene geklotzt. This is mostly due to how much work it has to do: the CPU-NB is the controller of memory. Wie wird das System schneller? AMD Phenom II X4 955 Black Edition. Each timing works with a corresponding DRAM Frequency. The voltage of your RAM will need to be researched. The CPU-NB is probably the most complicated part of the Phenom II. Work with it when you need to. Still using 4:1 RAM Ratio we would get these new results: You now have some really fast RAM (in fact this is most likely not possible for most RAM). Find your CPU in that list and click “view detail” to find the stock frequency and voltage settings for your chip. The main one being the Heat Wall (read more about that in my Heat Wall section). Use it for 10 mins to learn if it is somewhat stable. In 90% of cases this is true, but the other 10% of people have something called a BE or Black Edition CPU. This can be turned on or off. AMD Phenom II X4 940 übertakten. Which to me, is fine. CPU-Z will be used as an accurate tool to show what speed your CPU is at, and what Voltage it is at as AOD is not 100% reliable with this. As always the lord of all walls is the heat wall. Now that you are setup and ready to go, you will now start to increase the CPU-Multi by 1 and then hit Apply. AMD Phenom II X4 940 Black Edition. The next section is divided into three main parts. Thuban wants everything to be happy, and requires harmony between all four areas. Even though they are not as powerful as their Intel competitors, they create a different game when going cold. You may find that the highest CPU-NB frequency is not necessarily the fastest or the most stable. This was something never before seen from an AMD CPU. The speed of your CPU-NB is the max speed of your HTT. Bei AMD bieten sich vor allem die Phenom und Phenom II Prozessoren auf Basis von Sockel AM2+ oder AM3-Mainboards zum Übertakten an. Once your computer starts to crash during boot or during the benchmarks, you will need to try 1 of 3 different options. GTA IV spiele. 2 Stunden (ich weiß man sollte länger laufen lassen) laufen lassen und bekam keinen Fehler. From what I have learned, the HTT likes to stay with the CPU-NB up to 2800 – 3000 MHz. Depending on your RAM manufacturer there are a couple of basic timings that you will most definitely use while overclocking the Phenom II. AMD Phenom II X4 955 vs Intel Pentium 2129Y Sorry. This same process will work as well with the HTT. In order to find your speed without my table, you can use my formula: CPU-NB Frequency (+/-200) = (CPU-Frequency * 2 ) / 3.15. Make sure you know this before getting started. Shortly after the release of the Phenom IIs, it was discovered that they could still operate at a temperature below even that of liquid nitrogen (-196 C) . This was a nice refresher! AMD Phenom II X4 810. By using the equation from above you will be able to calculate your RAM speed. Just read it through again. If something goes wrong here is a common list of the error, explanation, and resolution as how to fix it. AMD Phenom II X4 965 Black Edition Box, Sockel AM3 Übertakten Hi, wie der Titel schon sagt möchte ich gerne meinen prozessor etwas übertatkten. Also note that the CPU-NB voltage should never exceed 1.35 v in any way. AMD Phenom II X4 955 vs Intel Celeron G3930: 3. Given its base clock of 3.2 GHz, with appropriate cooling, this unlocked Black Edition chip can be overclocked to speeds in excess of 4 GHz. Overclocking is not always a simple task. Now that you know how to determine the speed of your RAM, you can now set the timings of your RAM. Beim Phenom II schränkt das Drumherum der Plattform ein, selbst wenn man die CPU auf 4GHz übertakten kann. If no errors are thrown, and your Computer continues to run, this is considered a theoretical potential overclock of your CPU. The only way to get around it is if you lower the temperature even further. What you should get from this section is an understanding of the importance of the CPU-NB and how it affects your overclocking process. Table 2 is only a reference and may not apply to your RAM. It will allow you to understand how things work before implementation. The first way is the basic ratio, just like my table from above. In the next section I will talk about the CPU-NB a lot more. HowTo AMD Phenom X4 II 955 BE + Gigabyte GA970D3. In essence it will come down to you playing around with your timings and testing them to find the best balance of both stability and speed. There is no easy way of doing it, unless you do not want to see the best gain out of your CPU. Run wPrime 32M. I would first try to increase the Voltage before exploring the other two problems. NOTE: Please be familiar with your motherboard BIOS. You will not need most of the information, but it does not hurt to learn more about your CPU. AMD Phenom X4 9950 Black Edition. There are several different methods to overclock the HTT and CPU-NB. The memory frequency is determined from a ratio, composed of the FSB (Front Side Bus) Frequency and the DRAM Frequency (Seen as FSB:DRAM). Let run for 24+ hours, and you will know if your computer is 100% stable. I know the 7xx IGP chipsets (not sure on 785) are all 1.3v. Cracking article! In this section, you will learn how to overclock all Phenom II Black Edition CPUs. This will allow a sort of fluctuation with the CPUv and CPU-NBv.

This does not mean you will be able to run 24/7 on these settings, it just shows that your CPU can handle an instance of intense benching which means there is hope (sometimes very small). Wie kann ich diesen übertakten, bzw. Für den Fall, dass Sie nach wie vor Zweifel im Hinblick auf Amd phenom ii x4 übertakten empfinden, fehlt Ihnen wahrscheinlich nur der Anreiz, um wirklich die Dinge zu ändern. Please consult your motherboard manual to determine how to configure your RAM ratio. As a rule of thumb you should keep your HTT between 1200 – 2200 MHz when overclocking. If we include every cumbersome detail directly, the guide would be back up to the 50 pages it started at - an avalanche of information can hurt more than it helps. But, on the other hand, it may not work at all. Play around with it, and see how it affects your system in both stability and speed. A complete guide to the AMD Phenom II family. Im glad it finally is seeing the light of day thats for sure! 133. 215 * 14 ˜ 3000 MHz Core Speed. In practice it does not work 100%. Thank you a lot for putting this together Dolk. Lower numbers are better when talking about latencies. 3DMark 03, 06, and Vantage (Only for Windows Vista and 7). You have to watch everything: RAM, HTT, CPU-NB, and CPU. Wie wird das System schneller? In other terms: if the chip is cold it will scale better in overclocking. I would suggest that you do not touch the other settings not covered here unless you know what they do. I have constructed a table outlining the settings at which your CPU-NB should be with ‘X’ CPU Speed. If you do have a Black Edition CPU, it is still wise to read through this section. • Core fails: This happens when a core calculates values outside the frequency causing errors. $45.90: Zum Angebot: AMD Phenom II X4 955 3.20 GHz Quad-Core... AMD Phenom II X4 955 3.20 GHz Quad-Core Processor HDX955WFK4DGM Socket AM3 PGA-938 95W These are situations at which your CPU may be able to run at Y Voltage. Intel CPUs have historically struggled with cold temperatures, as the CPU would start to become unstable upon hitting a certain temperature. In most cases I have found that keeping the RAM at 1600MHz for DDR3 and 1066 – 1200 MHz, for DDR2  provides the best stability and performance. SuperPi 32M and 1M: Use this tool to check for somewhat stability. Putting It All Together explains exactly which steps to follow to find your maximum overclocked settings. AW: phenom II x4 955 übertakten Ich hab für dich mal die Screenshots von meinem damaligen 9 6 5er rausgesucht, vielleicht kannst du dich zumindest etwas an den Settings orientieren. The memory frequency can be changed by changing the the FSB frequency and/or ratio. Otherwise, maybe you’ve heard of it from the references across other enthusiast forums who link back to Overclockers.com for the instructions. Even though you have this powerful chip, you are still going to have walls that limit you as to how far you can go. The menu will allow you to choose the ratio you want. These timings are directly affected by the speed of your RAM. AW: Phenom II x4 955 BE Übertakten? First thing is first, for all CPUs: find your walls. So for this next example I will increase the FSB to create a 3010 MHz CPU or a 3.01 GHz core speed. Remember they have their own separate multiplier but they do in fact run at the same speeds at stock. AMD Phenom II X4 955 Black Edition. DRAM Frequency = [ (FSB Frequency * DRAM Ratio) / FSB Ratio ] * 2. The second section is “Overclocking with Black Edition”. First thing you need to do is get up to 3.4 GHz stable. If you have a BE CPU, there is no difference other then what will be talked about later in this section. For now you have found theoretical maxes to your CPU. Once your computer does not boot up any longer, this means you have found your FSB maximum speed. Check temperature to make sure that you are within range of Max CPU temperature. Just using the CPU multiplier I was able to up the CPU speed to a clock speed of 3000 MHz or 3.0 GHz. The 940 BE was the flagship CPU, in some cases reaching 4.0 GHz with water cooling and benchmarking with 3D Mark06 at 6.5 GHz. Even though I did say to resort to the CPU-NB last, it is still important to always refer to the CPU-NB when trying to create a more stable environment. Der Multiplikator ist ja standardmäßig auf x4.0 eingestellt. Ich ahbe den AMD Phenom II X4 955 BEm prozessor auf einem gigabyte GA-MA-790XT-UD4P Motherbpoard. The first Phenom II was the 940 BE which was followed closely by the 920. Please use Table 3 and Table 4 for more information on what CPU-NB frequency and Voltage you should be at.
