Slight problem with OC

These the settings I used to OC prior to going Xfire put them in yesterday and boots straight to BSOD.
Can Anyone see if I missed something or got something wrong ?

multi = x21
Vcore = 1.42v
imc = 1.35v
qpi = 1.31

speedstep = disabled
C1e =disabled
c states = disabled

I think with XFire you could try bumping up the QPI/NB volts a bit to get stability back. The more graphics power X58/P55 uses the load is put unto the QPI links (i think, not an expert here)

It could also just be driver problems though.

Thanks, gives me something to start with.

not a driver problem i had the same problem with my 4.6 ghz overclock once i went sli i could not get it stable at all had to drop my overclock down to 4.4 ghz

ended up going further down to 4.2 when i overclocked my 570's

try upping your qpi voltage to match your core voltage also change the n setting to 1 for your memory

I can only get 3.3 ghz stable atm I will give qpi increase a bash an go 1N on memory, thanks

Try qpi @ 1.36v and see if that helps.

Is hyperthreading enabled (just out of curiosity)? Also make sure turbo is disabled.

Ta, Turbo is disabled & yes hyperthreading is enabled
