I have a p6x58d premium and went from an i7 920 to a X5675 this year and have been trying to get it stable for the past 7 months, my goal when buying the X5675 was to reach 4.5Ghz stable but temps were good only when gaming, when stress testing with AIDA64 temps hit over 80C frequently, I'm on air with a Hyper 212 LED Turbo so I decided to bring clock down to 4.4GHz to finally try and get it stable. I still get BSODs from time to time, after so many tweeks and time working on it to get it stable makes me think the problem is with my RAM sticks not the overclock itself (the BSODs is always memory related, DRIVER_IRQL_NOT_LESS_OR_EQUAL D1), even though they were fine with the i7 920 overclocked to 3.6GHz and never gave me any BSODs I think at least one of the sticks might be dying, I recently used memtest86 to check for problems and each one passed flawlessly for over 20+ hours running though.
Before I bought the Hyper 212 LED Turbo I was running the i7 920 with stock cooler and stock speed, I had 6x4 sticks giving me 24GBs, after installing the new cooler I lost triple channel and had to downgrade to 4x4GB for 16GBs (the first 2 DIMMs stopped working), the stock cooler was dusty so I either damaged the DIMMs slots while installing the Hyper 212 or I just need to clean it up to get tripple channel back. The RAM sticks are very old ones that I've been using since 2011/2012, it's the corsair XMS3 with XMP for 1600MHz at 1.65V, soon I will be buying 3 HyperX 8GB sticks rated for 1600MHz at 1.5V to see if I can finally get rid of the BSODs once and for all.
Currently the CPU is at 4.4Ghz with 1.38V (23x192) and 1.35V QPI, I will be posting some screenshots of bios settings and other stuff while I try to get tripple channel back before buying new RAM.
