Overclocking fx 8120 stock

post #1 of 23
Thread Starter 
Hey overclockers

this is my first post so bare with me.

I've bought a rig with a fx 8120 on a ASUS M5A78L-M LX V2 motherboard with 8GB DDR 3 RAM 1333 Dualchannel ram. So maybe not the best rig, but I'm a student and I'm very price-aware. I have no additional cooling, so only a 420W ATX fan and the AMD boxed cooler to cool the CPU.

Would you recommend overclocking at all? I'm of course interested in optimal stable performance, I'm more concerned with having a stable rig, but on the other hand if overclocking a little bit wouldn't hurt I can't see the problem. So should I overclock the RAM or CPU and if so, what would you recommend?

Thanks a lot for any replies and reading material that can smarten me up.

You can try slight OC'ing which will primarily be limited by the CPU core temps. which you should keep below 61C under max load for stable performance. I recommend the latest version of "Core Temp" software as some software does not correctly read FX CPUs.

You should read the link below which has lots of info. for when you can buy a better HSF and crank the 8120 higher for fun and performance.

Thanks a bunch bro!

I should say that I have little idea what slight OC'ing would be. I'd rather not change the default voltage, as I'm thinking it'll get hot faster. I read that someone OC'ed to 3.7 or even 4.1 with stock cooling, but he may have had a better case and case fan. In any case being a rookie OC'er Id say that 4.1 ghz with as little modification as simply sliding the cpu multiplier would be a good babystep for me, if it proves to be stable. Were you thinking something along those lines, or should I stick with 3.7 and not even test 4.1?

I'm thinking I should stresstest with Prime95 no matter what I stick with. Agree?

Also - any thoughts on the ram - I had some ppl say that I should've gotten 1600 MhZ, what would the implications of trying to OC the 1333 be?

yeah, but the challenge does only last 10 days. any way, do you mind posting the rest of the system? like power supply, gfx card, etc. you can add it right to your signature- just click rigbuilder up in the top right of the screen and fill it out.

Worked, actually. ;)

I don't fold anymore and mainly because PG hasn't put out a decent AMD GPU core. 

If and when that does happen, I'll resume for the "enemy".

 

Anyway... Back on topic. 

I think the OP can overclock to 4 GHz stable with stock cooling.

folding is for charity! show some consideration. any thing will help, and the fx-8150 would put up some pretty good numbers
