I made this dumb post about overclocking my i7 920 back in the old thread, and it was suggested that maybe the problems I was having with stability were a result of poor cooling. I installed a Coolermaster 212+ Evo and my temps at load dropped from 83 to 68, give or take a couple of degrees. I used the same settings and ran Prime 95, but the stress test only lasted 30 minutes before it bluescreened out. At least, that's what I'm thinking is going on based on the HWiNFO64 log.My Dumb Butt posted:Settings are as follows: Any suggestions? I'd really like to make this 3.6Ghz overclock work.

grumperfish posted:Your BIOS settings look alot better now, and temperatures are in check at least. I never thought that maybe the RAM was what was loving up. I'll run memtest when I get home. I'll also run Prime95 again until a bluescreen pops up and write down the BSOD code.

So here is what Memtest 86+ v4.20 came up with: I'm guessing this is good, which leads me to guess that I'm hosed as far as a potential overclock is concerned. Right?

grumperfish posted:In BIOS, disable turbo to keep the multiplier at a specific setting. I think from your list it's: "CPU Ratio Setting: Auto" What should I set it to? There was a guide that you had linked me that suggested 15, but when I tried that, the system didn't boot. grumperfish posted:Check the Windows Event Log for the BSOD codes, so we can rule out harddrive failures, etc. code:
grumperfish posted:more grumperfish posted:Since you have 6 RAM modules running, try reverting to just 3 modules in parallel when you're going through the guide. It's possible that your CPU's IMC is having trouble with 6 modules & overclocking. grumperfish posted:If your board supports saving separate OC profiles, save one before clearing CMOS/reverting to stock. Worst-case, you recorded the values on the last page to work with. grumperfish posted:What motherboard are you using by the way? I think it was listed at one point but no idea where that post is.

I kept reading that my i7's stepping (C0) requires more voltage on average than a D0 stepping would, so I kept those previous settings, only I bumped the Vcore up to 1.4. I'm stress testing it now, and it's hovering around 83° C, which leads me to think that I should maybe keep the voltage at 1.375-ish and settle for 3.4Ghz instead of the current 3.6. Thoughts?

I ended up scaling back to 3.36 Ghz instead of 3.6. Load temps are around 65 with prime95's max heat setting. I'll leave Prime95 on overnight to make sure that it's stable enough. The vcore is at 1.25 I believe. I really hope this poo poo works out, because I'm kind of tired of dealing with this bullshit. It figures I'd get the (apparently) solitary 920 that can't do 4Ghz on air.

The 3.36Ghz overclock lasted throughout the night, so I've got something good going here, I think.Dogen posted:Well "air" is a relative term, what kind of cooler do you have? grumperfish posted:3.4ghz is pretty low for 1.35V. Even with a C0 chip, you shouldn't really hit any limits until up to ~3.8ghz. I'm using a recently installed Hyper 212+ Evo with Arctic Silver. I believe it's mounted correctly, but I suppose it could not be, and I wouldn't know the difference unless it was totally hosed and not dissipating ANY heat. Temps were at 65 max on Prime95's max heat max power test last night.
