  • make sure that's 100% stable, if not lower multiplier until stability is reached
  • find lowest cpu voltage, for me, it was 1.335V (bios) w/llc on ultra high
  • bring CPU PLL to 1.75V and make sure it's stable, if not lower one notch until it's stable. if 1.75V was stable, raise a notch until you reach instability and lower to the last known stable voltage. for me it was 1.7625V
  • bring up ram to rated speeds/timings. start at 1.65V to make sure it's stable at rated speed/timings. next try 1.60V still stable? try 1.55V. still stable? keep lowering one notch until you reach instability then raise back to last stable voltage. my 1600 9-9-9-24 1.5V runs fine at 1866 9-11-9-27 1.5V. i've read that ram which required 1.65v on previous gen, should run fine at 1.5-1.6V on SB.
  • bring vccio back to default 1.050V and make sure it's stable, if not raise it a notch until you reach stability, for me it was stable at 1.05V


If I didn't do it this way and left everything standard but CPU voltage, than my lowest stable vcore was 1.365 (bios) vs 1.335V (bios) from lowering cpu pll. With my chip/ram I didn't have to touch VCCIO after all.
Well your chip is obviously much better than mine even if you don't consider yours has HT. I'm setting it to 48x with vccio to 1.15v, pll to 1.75v, pch to auto, vccsa to auto, and vcore to 1.39 I lowered ram voltage to 1.5v and lowered timings to 8-8-8-22-2T.

Lets hope that works as 4.8 GHz at 1.415v, 1.8375v pll, vccio,vccsa,pch, and dram 1.65v 9-9-9-24-2T was 11 hours and 35 minutes stable (12 hours)

I updated the Linpack binaries on IBT and after several runs got a BSOD at 4.7GHz/1.30v. So this is my final 24/7 OC for now. I'm trying to keep the voltage as low as possible:

If that fails for you, how are you going to know what the problem was? IMO it's better to take it one step at a time to ensure you know which setting is causing the failure. Changing more than one setting at a time is to leave you throwing your arms in the air with no idea what caused the instability. Yes, it'll take much longer this way but having the satisfaction of having a perfectly stable system with the most optimal settings is worth it to me.

Here is my 4.6ghz i5 -2500k prime stable (about 20 hours) and 25 Runs IBT stable rig. It's not great at all, but so far it's the best I can come up with. I seem to NEVER get lucky with CPUs. I'd love to push it to 4.8ghz for 24/7 (maybe you guys can help).

vCore set to 1.385 in bios and under load it's about 1.376-1.384.

Anyway here it is!!

Thanks,

Brad

sorry but won't be accepted, please read the rules carefully.

Here is a reminded of the rules:

Quote:
Rules

1. 12 HOURS+ of Blend run.

2. MUST have a screenie WHILE UNDER LOAD with your ocn name (use notepad or something), CPU-Z 1.57 and realtemp 3.67 ONLY!!

3. List your overclock, voltage, cooling and RAM

4. Must have a mild overclock 4ghz+

Cpu-z 1.57.1 link: ftp://ftp.cpuid.com/cpu-z/cpu-z_1.57.1-setup-en.exe Big thanks to stasio.

Realtemp 3.67 link: http://www.mediafire.com/?91blrwtl1lenzal

Hey munaim, I'm still having those annoying BSODs popping up. I reinstalled Windows to make sure it wasn't any corrupt files and disabled Spread Spectrum. I even upped my VCORE to 1.30 and changed my RAM settings from 1T to 2T and I still get them. I don't understand how this is possible, especially when like my screenshot proved, I ran Prime95 for 12+ Hours at v1.29 with no problems.

Other than Spread Spectrum is there anything else I should disable? Such as Turbo Mode or Speed Stepping? or should I just keep upping my VCORE?

I get BSODs when running the least resource using programs, like League of Legends or watching a 480p Youtube Video. It happens maybe once every few hours, I once went 2 days without it happening.

could be a fault on the mobo or even psu related, it seems that your cpu bsods when your either idle or in low usage.

Post a screenie of hwmonitor

EDIT: Have tried flashing to the latest bios?
