Core i7/X58 Overclocking Thread

[SteveRo]

kind of a double post in a way but i've tried a bit more here..

new build is in sig, i'm out of ideas here. I've tried leaving all memory settings at auto, manually set 8-8-8-21 (rated speeds), tried lower cpu clock, 1.64v on ram, 1.45v on qpi/vtt, etc... i just can't figure this out. no matter what, anything higher than 1520 results in it just sitting there with a blank screen when trying to boot then shuts down, comes back up and it had to set memory back to default, which makes it 1066 on my board i believe

1520 appears to be working with no issues, but this is really hindering me from trying to get a 4ghz stable clock down because that requires 1600mhz

anyone have any ideas?

i noticed in cpu-z that my SPD for 1600mhz is coming up as 2T...is this true? I was under the impression ddr3 can run 1T..i havent even tried 2T

Damien - I do not run 2gb strips, others do and some have reported problems.
I have similar gskill memory as you but the 3x1gb (2k) and they work great.
One thing I noticed when setting the bios to use xmp - gskill has the xmp set to run the qpi/vtt all the way up at 1.5 to 1.55v!
So - 1st question - have you tried with xmp on?
Then 2nd question - have you tried with high qpi and mem v - for testing and even over night - 1.55 qpi and 1.84v memory v will not hurt you.
I would recommend that you keep qpi and mem v within .5 volt of each other.
