I have a 2500k cooled with a H100 in a Gigabyte GA-Z68XP-UD3P. When I first got the H100 (was after the chip had been burned in), I immediately OCd to 4.5GHz. I disabled C1E, speedstep, all that jazz, turned on PLL overload, changed multiplier to 45 and kept getting 0124 BSOD, so I continued to increase vcore and it wouldn't get stable in prime95 blend until 1.375v, which from the infinite amount of threads I read, is pretty high for 4.5GHz.
After a few months, I noticed that at some point it reverted back to the stock multiplier, so I went to change it back to 4.5@1.375v, but it kept BSODing. I got all the ways to 1.395v before it could even clear one pass in prime95 before it would eventually 0124 BSOD per usual - definitely wasn't going to touch 1.4v even if the temps were still okay.
Any idea why this is happening? Crappy chip? Am I doing something wrong? I've been building computers for awhile, so I know the H100 is seated fine (temps are great) - I have just never been OC-savy.
