I have an Asrock X58 Deluxe motherboard with an Intel six core 980x processor with 24gb Patriot PC3-12800 1600mhz memory. I am looking for stability, not overclocking. With the BIOS settings all on AUTO the CPUz says core was 1.168, core @ 3.466, multiplyer 26, bus speed 133.3 and QPI 3200. I ran Prime95 and after about 4 hours the computer restarted and the minidump said it was "Bugcheck 124" which I believe is associated with CPU voltage. so I bumped up the voltage in the BIOS for the processor to 1.26250. Back in Windows 7 in CPUZ it says the same multtiplyer, core speed, bus speed, QPI with the difference showing the voltage as 1.200 (rather than 1.168 as before with AUTO setting). I run Prime95 and keep CPUZ open and the voltage went from 1.200 to 1.152. I turn off Prime95 and it went frolm the 1.152 back up to 1.200. Hrrmm, so I turn on Prime95 again and sure enough, it went from 1.200 to 1.152. I'm a bit confused. Shouldnt the voltage stay the same, if not go higher, during 100% Prime95 load? Can someone chime in on if this is correct and/or what settings I should have for stability?
