ep45-ud3p e8600 I WANT THE BEST I CAN GET

[nav-jack]

so my specs are:
ep45-ud3p with F7a bios
e8600 @ 4051mhz with easytune6
mushkin 2 gig memory @ 1800fsb
gtx 280
tuniq tower heatsink
coolermaster cosmos case
610W pc power and cooling PSU

this is mainly an intro post but also i would love some experts here help me figure out this voltage thing cuz i know easytune gave the cpu possibly a bit much, cuz i remember from some posts that in bios u should get away with about 1.25xxx but easytune gives me 1.376. i have no issues so far with heat or stability, i just would love to run this at full tilt and also get past this one question. which is faster, raw cpu ghz OR a faster memory fsb and mobo fsb etc etc.

im gunna have to bump for great justice

[SpeedEuphoria]

ET6 normally gives way too much PLL and cpu termination

So its best to set those manually in BIOS, just take note of the other settings that were changed to get that OC, you likely also can get by with less V core

Post your full bios settings for more help

Like this:These are mine on stock Vcore and 2x2GB OCZ ram w/ E8400 and UD3P

Ya, dont use Auto for voltages for sure! What Vcore you need all depends on your CPU, just set something high you know will boot and then go in windows and look in CPU-z and compare what you get vs what you set in the BIOS and keep that in mind. Then just lower the voltage till it wont boot then raise it back up a few

Here would be optimal ranges for your setup at 4Ghz. Before you use any of this write down your disk settings from the integrated peripherals page because you need to load optimized defaults. I see you have loaded fail safe, you should now load optimized and set your ram voltage ONLY and then save/apply/reboot BACK to the BIOS and make all your changes again including (And do not forget especially if you have a RAID Setup) to set your disk settings again. If you do not and you have RAID and you let windows try to load with incorrect disk settings you will loose your raid array.
