Core i7/X58 Overclocking Thread

rge - got it, running p95 at your multi's and volts, except vcore at 1.36875 (same as what was stable for me for 12hrs p95 at 134x30).
currently priming at 191x21 - 4.01ghz, temps are lower by approx 5C so far! excellent!
max temp so far down from 75 to 70C
I will let this run for an hour then drop another -1 on cpu v.

Be interesting to see final vcore/temp difference high bclk to low bclk for same mhz...keep us posted.

saaya was telling me that temps over 80 are no good for 24/7 use , what do you guys recon ?

my temps under 100% load are sitting around 80c but sneaked up to 83 for a few seconds earlyer

I would not worry the least about 80C load temps for 2 reasons. First, if its only prime that gets you there, then prime temps dont really matter, unless you are folding 24/7 with same temps. And 2nd, all cpus per intel are calibrated such that at max load tjmax is reached (~100C on corei7) when tcase max is reach (~67C on IHS on core i7 if memory serves me correctly). At 80C prime load you are definitely going to be within tcase max specs.

Granted for every 10-15C drop in temp you double the life of the component, and I will do everything I can to get them lower (except reduce my stable OC), but given upgrade cycle is rarely longer than 3 year intel warranty period, my main concern with prime temps is stability, and if not hindering that, not even 85C max temps would I let hinder my OC.

i agree,

the thing with i7 that is spinning me out is a 13 to 20 hour prime run and it might still not be 100% stable, like i said ive had prime error after 18 hours, and the other day i primed for 21 hours small ftt, then ran 2 smp folding clients over night and by the time i got up the pc had crashed, so 1 prime run isnt enough,

edit... that was @4ghz that i ran the folding clients so load temps were around 70c max

As has been said small ftt doesn't seem to do much to the uncore (l3 cache, IMC), i'd stick to running blend.
