It will climb to max volts during 1-thread load if you have c3 and c6 states disabled only. If c3 and c6 is enabled, just run 1 thread of prime95 to see what volts you'll get in cpu-z. However, more than likely it'll crash when you try to do this. I don't see you getting that overclock stable using offset without disabling c3 and c6 because 1-thread loads will be unstable (you'll crash while gaming even though you're 12 hour prime stable)

You just need a modern hard drive. The one in my sig records @ 1080p 60FPS with plenty of headroom. I partitioned the hard drive into 2 sections and record to the first partition to ensure the outside of the hard drive is always getting used for fraps and to also ensure that fragmentation never causes stuttering because I keep that partition empty.

Thanks again though man. Really appreciate all your help.

You're Windows install can become corrupted after too many BSOD's i believe. I don't know how much that takes and i don't believe it will happen after just a few times. When i was overclocking i estimate i had somewhere around 20 BSOD's.

Anyways i would try and use manual voltage instead of offset it will be easier to get stable and i believe hambone (good overclocker here on OCN had a thread about it that it works better for OC'ing)

Also what BSOD code do you get when it fails? Its possible to get a indication of whats wrong with your OC for instance if you get a 101 its probably vcore but if you get a 124 it could either be VCCIO and/or PLL or in some cases a vcore issue.

Doesn't manual voltage lessen the life of the cpu though at such a high voltage?

I'm not entirely sure what code I get, each time it happened I just panicked and ran for my reset button haha. I just hope to god it doesn't happen again when I lower my CPU PLL to 1.7v and set my VCCIO to 1.15v. If all else fails, I guess i'll try and remove a set of RAM from my mobo and see if it helps at all.

Running 4 sticks makes a DRASTIC increase in the difficulty of overclocking. Before i had 4 sticks i could do 5ghz @ 1.32v 24/7, now with 4 sticks it takes me 1.37v for 5ghz stable. Max safe is 1.55v.

code 124 could also occur during the idle bug, in which case C3 and C6 states need to be disabled to prevent reocurrance

I have heard of windows getting corrupted due to BSOD, I have never experienced it myself however and I have been overclocking since 2006.

Just got to overclock smart, if you try an overclock at a certain voltage and it BSOD's soon as it hits the desktop, you should raise voltage by a lot more than you would if it BSOD after 4-5 hours of prime95 blend.

1.you have an amazing chip! If you ever wanna get rid of it gimme a shout wink.gif
2. Couldn't agree more 4 sticks make it much harder to OC as per my experience with every CHIP since first generation dual cores. But Sandy Bridge has been the most difficult to work with when running 4 sticks, I spent a long time tweaking to try and get it stable, it just wouldn't budge. And mind you I was only running ram at 1600Mhz, I can only imagine how much harder it would have been at 2133

I should have mentioned i'm running the first test in Prime95, not the blend one. Should I have been running this one instead of just the cpu stress one? Didn't think the ram would play such a huge part in this, but I guess I should go ahead and remove a set from my mobo and run a blend test?

EDIT: my CPU C3 and C6 reports are disabled as well.

Oh my god! Yes only run Blend. The other ones are actually terrible on Sandy Bridge for whatever reason. The first one is small FFT's right? Blend will actually run at a cooler temperature than small FFT as well.

Do this:
1. Start Prime95
2. Click on Blend
3. Click on Custom
4. Set memory usage to 14745 (90% of your memory)
5. Start the test

By using 90% of your memory it will identify instability much quicker.

does this mean I damaged my cpu by running the small FFT? Yes, the first one is the small FFT, please tell me I didn't ruin my cpu.sadsmiley.gif

sweet thumb.gif yeah give 1.44V for 5ghz a try. but i ended up lowering my clock to 4.5ghz and never noticed a difference in gaming or anything.
(I play old republic and it does the job just fine.)
plus if you leave it at 4.5ghz @ 1.28v you should see idle temps at 29~31c

Dude you're not going to damage your CPU. Stop worrying.

Small FFT just is not effective at all in detecting instability. It's not gonna harm your CPU.
