Hey guys, I bought a 2500k about a year ago with an ASRock Extreme4 Gen3 and overclocked it to an easy 4.2Ghz using the default settings and tweaked settings a bit so it didn't use as much voltage. It's been perfect for that time, but I've recently changed to a SeaSonic x750, from a PC Power & Cooling Silencer 610w because of the noise, and I decided to manually overclock it myself.
I figured I would test the overclock since different PSUs do different things, but I guess either my overclock wasn't totally stable or Prime95 a year ago was easier to pass without AVX instructions. Anyways, I managed to get it stable for 28 hours using Prime95 blend test with Vcore at 1.28, which loads it between 1.256-1.27 with LLC Level 3, when it BSOD 0x124 while I was sleeping. Currently, I have it running again with VTT up a notch (1.064), since people recommended trying that, but I was wondering if I should up it another 0.005 of Vcore to get it stable (seems like a lot of voltage for 4.2Ghz). From what I've read almost all chips require nothing but Vcore up to around 4.4-4.5Ghz.
Temperature of the cores are pretty low at this setting being anywhere from 47-62 depending on tft size. With 4.4Ghz it maxed around 70c (mostly just curious how much Vcore I needed to run for 4.4).
Basically, I'm just curious what the recommended path should be for this. I have yet to get a BSOD while doing anything other than prime95, so I think it's just the overclock or one rare spike down, but I don't know. I was also wondering about the option spread spectrum; I turned it off and reset my BLCK to from 100.1 to 100 (my OCD at work), but I can't imagine that having any drastic effect. I've turned off the Cstates since my PC never seemed to like those options on. Most of the other options are auto with my Ram being the settings recommended on the package/stickers (upped voltage to 1.3v from 1.25 since G.Skill recommended this). Last question I had will probably come off as a bit noobish, but I wasn't sure if the overclock degrades over time and requires a bit more voltage after a while.
Sorry if this was a bit long. Thanks for any helpful replies in advance.
Edit: Should I be worried about data corruption on my OS ssd from a few BSODs?Edited by Bobber1 - 9/23/12 at 12:13pm
