QPI/VTT Voltage, IOH Core, and DRAM Voltage on auto?

post #1 of 2
Thread Starter 
I've been trying to get my i7 to 4ghz but was having trouble getting the correct voltage on the vcore. I already made the mistake of having everything on auto (stupid motherboard had it like that stock) It seems no matter what I did I couldn't get it stable.
I had everything besides the vcore at what the mobo told me.
QPI/VTT Voltage 1.175
IOH Core 1.1
DRAM Voltage 1.5

Then I decided to put those back onto auto and everything seemed to be fine with the vcore at 1.29 which before it wouldn't even boot at 1.29

I come here to ask is it ok to keep the qpi/vtt voltage, ioh core, dram voltage all on auto?

Start with
1.35 Vcore
1.29 QPI

Underclock your memory. Test for stability. If successful, lower the Vcore.
Keep doing this till you reach lowest stable Vcore.

Then start bringing your memory up to speed.

This the very basic. Plenty of other parameters that can be tuned.
Use Google. Plenty of detailed i7 OC articles.
I leave very little in the bios set on "auto".
