One more E8400 OC Help Thread

post #1 of 9
Thread Starter 
I seem to be stuck with this OC. I can get it to 3.7GHz (411x9) at 1.33v in the BIOS...so I tried bumping it up a bit, to 418x9, it wasn't stable, not even when I took the voltage up to 1.3625...thats quite a voltage jump for only +7 in FSB. I tried to see if maybe my FSB just couldn't go that high by trying 450x8 at 1.3v and it was stable. There has got to be some kind of bottleneck here, I'm pretty new to overclocking so take every option into account. Other settings I have at my current 3.7 OC are 1:1 ratio, RAM +0.2 (2.0v), NB +0.2, FSB Overvoltage +0.2, RAM timings are 5-6-6-16 2T. Could this just be the limit of the chip? It really doesn't seem like it to me since I'm not at the limit of my voltage. Thanks for any suggestions, all I really want is at least a stable 3.8GHz.

no your ram dosent overclock very well if you have the cheaper sets. if so then thats your problem. i had a set of Gskill ram that wouldnt do 820 at all. and you cannon unlink the CPU from your ram either.

Check your memory and fsb while underclocking your chip to take those out of the equation as issues, i.e. lower the multiplier and try the same fsb freq it was unstable on.

It's apparent that the E8400 CPUs are a mixed bunch. Some OC really well, others not to much. I can't get mine past 3.8 without issues. I am seriously considering returning it to Newegg for a replacement, hoping the replacement will OC better.

I kinda already did that with the 450x8, it was stable there so no reason it shouldn't be stable at 418x8. Also, I can't unlink my memory, I can change the memory multiplier but I can't manually change the memory frequency.

Hmm I think you're right then, sounds like the chip.

I was thinking that as well but then he mentioned he did 450 1:1, so I don't think that's it.
