post #1 of 8
Thread Starter 
Hi there!
i have a fx8120 @ 21.5 x 205 (4407 mhz ) running stable with v core 1.58 wich i think is A LOOOT
My problem is, i cant pass 4.5 ghz without rising the vcore... and i think i might be missing something.. all amd core performance boos disable, etc. temps about 58 @ full load..

My pc spec
Amd fx8120
mobo: Gigabyte 970 ud3
2x 4g DDR3 1866 corsair vengance
xfx radeon 7850
corsai vs650wt PSU
Corsair H80i watercooling

Hey, welcome to OCN!
You may want to start by giving this a look through
http://www.overclock.net/t/1140459/bulldozer-overclocking-guide-performance-scaling-charts-max-ocs-ln2-results-coming

There are other guides as well but this one is for Giga mobo's.

Post back if you can't find a solution.

Hi. thx for the answer, iam quite familiar with oc, but the thing is that now im runnng @4.4 ghz with 1.53v . if i get any lower vcore it gets unstable.
i change the multiplier to leave it as 22 x 200
the normal vcore after disabling the core performance boost, started at 1.38v
now im 1.38 + 0.150v to get the 1.53v and get it stable on p95...
far as i know u should be able to get 4.4ghz with much less vcore, so i dont know why i need that high voltage

how high can you go without being stable in prime, but stable in games/apps?.....also try and not go over 1.55v with that chip. I killed my 8120 and a 6100 by going over that. well, not really killed them, but both refused to clock as high as they used to before

Not saying it is, but it might be the mother board holding you back. The vrm's might. Not be powerful enough or its simply your chip that isn't able to clock over that much.
