well thats what xmp and epp are meant for, they can set vdimm too, but what i mean is that some mainboards BIOS increase vdimm to much more than the xmp has programmed in it (up to 2.1v) if you select high bclock or memory clock settings.

last night i worked out that i can run much higher QPI with lower uncore than first night
i will do a thread soon to report my findings which will hopefully save a few headaches for ppl OCing GB boards at very least i hope
huh? your xmp profile increase uncore voltage?
and to 1.55v? wee, thats a big high isnt it?
i mean everybody is running 1.55 uncore when pushing i7 it seems, but it shouldnt be the default setting!

you can run higher qpi with lower uncore, what do you mean?
higher qpi ratio? higher bclock? higher overall qpi speed?
with lower uncore voltage or lower uncore ratio?

update about the first dead i7:
it was a 965 and it died after one day of 2.2-2.4v vdimm
