How to OC an 8320 to 8350 frequency?

post #1 of 7
Thread Starter 
Hello everyone,

my main concern regards the turbo boost and how it'll be affected after overclocking - should I disable turbo boost after increasing multipliers or could i up the multiplier and still get a turbo boost similar to the 8350 (4.0-4.2)? My cooler is a Hyper 212+ with 2 120mm fans. Max temps on stock frequency is 52c but it usually stays around 48c.

With most FX chips you can set the turbo where you want it. If you set turbo to manual then you can set the multiplier for it.
So If you want a FX-8350 performance out of a FX-8320.
Set the following
1) CPU multiplier to x20
2) CPU voltage to 1.4v
3) Set turbo to manual
4) Set turbo multiplier to x21
5) Hit F10
6) Save and exit
7) You are done
8) Have fun

I did all the above and it boots and runs fine! I just have one question: the only CPU voltage I could find was already set to 1.425. Is that stock for the FX8320 @ 3.5 or does that refer to the 4.0 boost? I just left it as it is

I know for a fact that the 8350 runs at a voltage of 1.360 on stock according to CPU-Z.

Since the 8320 is really just a less stable 8350, I'm pretty sure that 1.425 as the voltage will work just fine.

What I would do is run some tests with prime95 to see if it's stable. Then bump the voltage down a notch and run the tests again.

This is the motherboard by the way: http://www.gigabyte.com/products/product-page.aspx?pid=4396#ov
I purchased it because of the 8+2 VRM setup


Here is a CPUID picture:


The max voltage is shown as 1.456v on the core. Will my 8320 require a tad more V's than an 8350 to be 100% stable? And as for the 8350, is 1.360v for turbo as well or just 4.0?
Later I will run prime95 and if it is successful I'll drop the Vcore a bit.

Use CPU-Z to see the voltage for your CPU. It is better.

I did, and I noticed the frequency was stuck @ 3721mhz and it didn't matter whether I changed power-state to balanced/high-performance - V's were 1.376 max. So, I went in the BIOS and disabled APM and now the frequency goes all the way up to 4228 but the core voltage shows as 1.29v in CPU-Z and 1.328 in HW Monitor.

wat


EDIT: I ran P95 on Large FFTs for about 30 minutes. Max temp 47c and no errors so far. I went on to play BF3 for about 30 minutes as well, but my temperature never went above 40c. My cooler is a Hyper 212+ with 2 fans and I have a push-n-pull system in the case to cool it better. Also, on HW Monitor the TMPIN1 (i assume it is the socket temps) was just a couple celsius higher than my max, which is normal. What could explain this drop in temperature after the overclock? Less volts?
