Tested my i7-930 overclocked to 4GHz with P95 blend for over 14 hours last night, figured it was stable enough. Some of the details...
Gigabyte X58A-UD3R board, on the latest BIOS
191 BCLK x 21 multi
VCore @ 1.26250 & QPI @ 1.24
Turbo off, C1E off, EIST off, HT on, thermal protection on, LLC stage 1.
Memory multi @ 6, which has the RAM at 1146 or so (RAM is 6GB of Dominators 1600).
All other voltages and ram settings are set at AUTO
Temps were fine, topping out at 77 or so with my H50 cooling it. No BSOD...
This morning, I wanted to turn on the settings that I had disabled for the OC so I turned on turbo, C1E, EIST. Before the Windows 7 start screen, BSOD. Turned off turbo, got into Windows 7 fine. I ran P95 on blend and left for work, came back home 4 hours later to a BSOD saying "MEMORY MANAGEMENT" ...0x1A.
Considering last night was fine and the only changes were turning on EIST & C1E, what could be the issue? Do I need to turn up my RAM voltage?
Thanks guys...still trying to get the hang of OCing.
Turn your settings back to stock, download and run memtest86, If it dont bsod at stock settings. If it does bsod at stock settings try each individual stick at a time until you find the one causing the bsod. It could be memory or it could be your settings but it is best to rule out memory first.
