FX8350 OC paired with Asrock 890GX Extreme4 R2.0
FX8350 OC paired with Asrock 890GX Extreme4 R2.0
Hi, I recently swapped in an used FX8350 to replace my Phenom II 965BE. It really boosts multitasking, but gaming performance isn’t much better than the 965. I attempted an overclock but couldn’t do it. With the 965BE, I was able to reach a stable 3.8GHz by air. How can I achieve the same with the FX8350? Does my 890GX chipset support FX OC? I have a 1.50A beta BIOS. Thanks.
Don't anticipate a significant performance boost from the Hyper 212 or the FX 8000 series. The problem seems to stem from a voltage concern. Although the standard voltage for that CPU is sufficient to reach 4.1-4.2 GHz, the issue likely lies in the CPU/NB voltage. Since the motherboard doesn't officially recognize this CPU, you might face overclocking difficulties. (EDIT: I was reviewing the first revision, not the second, so this part is irrelevant.) Regarding performance versus the 965, it's interesting to note that the Phenom II 965 at stock speeds offers better core performance with FPUs, which are heavily utilized in many games. Now, the "8" core CPUs only function as 4 cores with Hyper Threading, allowing each core to manage two threads simultaneously—but only...
Your motherboard isn't compatible with the 8350. It might be helpful to search for a used version nearby that fits your CPU better.
Sorry, I didn't note that my motherboard is Extreme4. Auto detected 4.2 stable, but manual setup isn't possible for me.
The manual is present but the system still fails to start, even after a minor overclock to 4.1GHz. I've disabled the turbo and adjusted the settings for quieter operation. To improve cooling, I'm using the CoolerMaster Hyper 212+.
Manual is present but fails to start even with a minor overclock, 4.1GHz. I disabled turbo, kept it quiet and cool. For better cooling, I'm using CoolerMaster Hyper 212+. Be cautious with the cooler—ensure it faces the back of the case and the fans run at high speed. You must cool the VRM. Check the warning on the Asrock page: http://www.asrock.com/mb/AMD/890GX%20Ext...0/?cat=CPU. It's strange it won't boot... what voltage is set in manual? Is it auto mode? Does memory speed also default to auto?
Don't expect to get a very high OC with the Hyper 212's and the FX 8000 series. The issue is most likely a voltage issue. While the stock voltage for that CPU is enough to hit 4.1-4.2 GHz the issue is most likely in the CPU/NB voltage.
Because that motherboard does not officially support that CPU you may end up having issues with over clocking. (EDIT: I was looking at the first revision and not the second So this part is null and void. )
As to the performance compared with the 965, believe it or not the Phenom II 965 at stock clocks have a better per core performance with FPU's in which games use most of. Now the "8" core CPU's are only actually 4 cores with Hyper Threading so each core can can handle 2 threads at a time BUT only the main core can calculate FPU "Floating Point Units". So this is why the Phenom II 965 BE CPU's actually out perform in a gaming environment. The reason you actually see an increase in games in FPS is because the other 4 threads, non FPU, are taking the load off the main 4 cores that actually do work on the game where as the 4 Cores of the Phenom II need to work on the game as well as other things. Strength in numbers in this case. This is why the Phenom II X6 CPU's beat all of the FX X6 core CPU's when it comes to gaming.
