OC FX-8120 BIOS settings for a stable 4500 MHz - Page 11

post #101 of 175
Over Tighten the CPU cooler cause the mother board to be bent just so slightly that the gold pins aren't touching the board. So reply paste and tight the CPU cooler down just a bit snug but not tight.
What board are you Overclocking this on again.
CrossHair is Easy to overclock on and i can help out on that seeing that i have overclocked my CHV and 8120 set up to 4.3 not going to push it much past that due to Temp keeping them under 55c.
UD3 i have a 6100 at 4.4 and its kinda easy but much more of a pain then the Crosshair.

I've had one nagging question...Should I go and get some faster RAM like 1866 or maybe even 2100 MHz or stick with my 1600? I've notice a lot of you have 1866 or higher...

Thanks...Now I can go back to bed!

i reply the paste and only fit the screws, im using CH V.
the temps are so high, and i noticed that the heatsink around the cpu (i think VRM?) are so hot, 50+ even 55°C

Disable Turbo Core / C6 / C1E / Cool & Quiet then lower your ram timings to like 1333 and yes nb should be less or equal to ht link depending on how high you set it.
Mine is NB = 2200 (Stock) HT = 2600 (Stock) / FSB 200

tight no more! i set the nb and ht speeds, the llc to high and very high and the pc booted in w7, but when i run the occt the pc reboot or BSOD or freezes, when not reboot or freezes the some cores fails.
i'll try more voltage at night.

im thinking in change to 4.0 again.

here are my screenshots

any idea of why the temps are so high? airflow is very good here, and the ambient are 28°C
post #105 of 175
28c ambient is very warm and it wont get colder just because you have a good airflow.. i'm sorry but i think you need to lower your ambient temp or get a water-cooling solution

here are the results that i had on a 2 min run....

I might consider you might not get 4.5 on air but we will cont to try.

You won't get a error on 2 minutes, try for at-least 30 min to ensure stability.

Trust me. Here is where the real challenge begins. You will need to experiment with the RAM frequency multiplier, as well as the reference clock (fsb). First make sure you know how to clear CMOS, because you will be doing it a lot.
What I would do first is manually loosen up your timings to something like 10-12-10-30-40 2T. Don't worry, you'll tighten them down later. Set your voltage to the highest your RAM is rated (check in the SPD tab or XMP tabs in CPU-Z or BIOS), usually 1.65V.
Then try booting with your highest available multiplier. If that one doesn't work, try one lower, ect.
Then you will start raising fsb while simultaneously lowering your other multipliers (CPU freq, HTL, NB) to keep them close to the settings you had when you found your CPU overclock.
When you crash or fail to boot, try raising CPU-NB voltage. Be generous here. AMD recommends up to 1.45v if needed on air cooling.
You might also need to raise your chipset nb (ht) voltage. Stock is usually around 1.1v or so, but don't be afraid to set it to 1.3v if needed.
When you find your best stable RAM frequency, we can move on to part 2, the timings.

Ok, I have been playing around with everything you have mentioned but nothing is stable. I have no problems booting into 4600 to 4800 MHz but of course, the system locks up or crashes!

So, when I start...Where I am I starting from, my last highest stable setting, 4600 MHz at 1.47v or a couple below when the voltage wasn't as high?

Cheers,

X


PS. Max RAM voltage is 1.5v form my RAM.

Im stable just showing that what temps are for 4.2 on air. in a two min quick test.
