AMD FX 8320 OC to 4200mHz

[BS Sunil Reddy]

Hai,

I can only run OCCT and Intel Burn Test but my temps are increasing as I am using Corsair H60 Cooler.I cannot run Prime95 successfully.

Cpu: FX 8320
Name: bavusani
Frequency: 4200
ref*multi: 200*21
CPU voltage: 1.38
CPU-NB: 1.30
NB volts: 1.2
RAM: 8GB 1600Mhz DDR3 9-9-9-24T @ 1.65V
Motherboard: Asus M5A97 R2.0
Cooling: Corsair H60
OS: Windows 8 64-bit
GFLOPS: 60 (Only for LinX)

How much more OC head room is there as my present speed is 4.2GHz. Is the above tests enough to conclude that my RIG is stable for any Gaming sessions.

Thanks & Regards,
bavusani

If it can't run any stress test, it's not stable. It's pass/fail regarding games will probably depend on the game and the situations within the game.

For how long have you run the tests? 10 minutes? 20 minutes? An hour? 3 hours? One hour is considered a minimum, 2-3 hours is about right for a thorough stability test. Also make sure you have turbo disabled, that can sometimes make the CPU quite unstable when overclocked.

And the OC headroom depends on the chip, my 8320 reaches 4.46GHz on 1.380V while yours is unstable at 4.2. You,for example, have no OC headroom - the CPU fails tests, either raise the voltage or lower the frequency. If you can't raise voltage, lower BCLK by 1 and see where that takes you, sometimes even 1MHz can make a difference between a stable and unstable OC.

Not even for 5 seconds I can run Prime95 with my AMD FX8320 overclocked to 4GHz.What could be the problem?
I am going for i5 4570 with GTX650Ti Boost 2GB. Is this good for gaming for at least 3 years?

Reading back at your first post, I have a feeling you fiddled with your RAM, and if you did - return RAM settings to stock. CPU OC instabilities are very often caused by faulty RAM overclocking. Seeing as how other benchmarks that are purely CPU work but Prime95 which runs a CPU/RAM blend test fails, I'd bet my left leg that RAM is the cause of your problems.

Oh, and put a fan to blow over the VRMs, if you don't have one already.

To be honest, I got no idea. Octa-core FX-series (mainly the 8350, 8320s are rare in game benchmarks) and i7s seem to have an advantage over the i5 lineup in multi-threaded games like Battlefield 4, FarCry 3, Crysis 3, and so on. But the adoption of multithreading among game devs doesn't seem to be that common at the moment so i5s are still great CPUs for gaming.

Put simply, it depends - if multi-threaded titles begin coming out next year an i5 won't be adequate, but it will be just fine if game devs stick to the current state of things.

Thanks for helping me out.
