FX8350 OC with Asrock 890GX Extreme4 R2.0

[lesp4ul]

Hi, I recently got an used FX8350 to replace my Phenom II 965BE and it's really improves multitasking , but in terms of gaming, not too much compared to 965. So I tried to OC it but i can't do it at all. With 965BE I can clocked it to 3.8GHz flawlessly by air. How to do it with FX8350? Is my 890GX chipset motherboard doesn't support FX OC? I have 1.50A beta BIOS.

Thanks.

Your motherboard does not support the 8350. http://www.asrock.com/mb/AMD/890GX%20Extreme3/?cat=CPU

You're lucky you even got it to boot up.

Try looking for something used locally that will better suit your CPU.

Sorry, i forgot to mention my motherboard is Extreme4. With auto it clocked 4.2 stable, but i can't do it manually at all.

O.k

That motherboard does support the CPU then, but just barely.

What do you mean you can't do it all? Like manual mode is disabled? Or it just won't boot when you O.C? What kind of CPU cooler are you using?

Manual is available but it won't boot even with a slight OC, 4.1GHz, i turned off turbo, cool n quiet etc. For cooler i'm using CoolerMaster Hyper 212+.

Be careful using that cooler. Make sure it's pointed toward the back of the case and the fans are on an aggressive setting. You need to cool the VRM's. Look at this warning on Asrock page.

That's weird it won't boot...what is voltage set at when in manual? Is it on auto? Is memory speed on auto as well?

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.
