Failing after a year?

[alnajjd]

First off I would like to thank anyone who assists me. My problem is i overclocked my system about a year ago and it has started to bsod (0x0..124) on me during gameplay.

• i7 930, oced to 4.0ghz (200x20)
• 12gb DDR3 Tri-Channel 1600mhz (6gb kingston(new addition)x6gb corsair)
  9-9-9-27
• 2x500gb Seagate 7200rpm drives (Raid 0)
• Evga 560ti SC DS (new addition)
• Corsair 750w powersupply
• Gigabyte x58-ud3r motherboard
• Water Cooled, Apogee gtx, small pump, only cpu on loop

I had my system stable at 4.2 at one point, when that started failing I switched to 4.0 and now this is failing. Memtest was clean, I reinstalled windows and updated all drivers. My voltages are such:

• Cpu Vcore - 1.36875
• CPU PLL - 1.8
• QPI/Vtt - 1.435
• IOH - 1.3
• DRAM - 1.64
• PCIE - 1.5
• QPI PLL - 1.1

Havent been in "overclock mode" for over a year so just looking for some tips on what is going on, lastly my cpu is running at mid 40s to 50 idle, low 70s to low 80s on small fft.

Sorry for the long post and I appreciate any help.

A Vcore of 1.36V+ seems awfully high for a 4.0GHz clock on a 930. Lower the Vcore to 1.25-1.30V (~1.28-1.32V while running Prime), bump PLL voltage to 1.88V, lower the DRAM multiplier from x8 to x6 = DDR3-1200, lower the QPI/VTT to ~1.30-1.35V, bump the DRAM voltage to 1.66V, and increase the QPI PLL voltage to 1.20V. Disable C1E, EIST, C-States, Spread Spectrum, and Turbo. Then run Prime or LinX at these settings, and don't worry about the lower than rated DRAM frequency for the time being.

How new addition is the ram? That would lead me towards that if it is that recent. I know you said you ran Memtest, but maybe it's Vtt
