latest OC result by me, i7 2600k @ 5.0Ghz, 1.4V
TEMP result:
Without Prime95, 36c~45c
With Prime95, 65c~76c

Without Prime95

Is it safe to run at 76c for gaming only? not really 24/7
*
for me, its definitely depends on person whether they wan to run at that speed 24/7.. intel safe temp is 71c if not mistaken
60c for me is hot ody.. bt some ppl can cope with it..
and overclock will decrease ur comp's life..
so if u ok with all that then u can stay at that speed..
it actually depends on whether u wan it or not sweat.gif

for me i dun wan my comp to run more than 50c, it makes the room hot..
if u wan it reli 'safe', then u may juz refer to intel safe spec

thanks for the correction..yes i meant the 2500k. Is there any major improvement from i5 2500k to i7 2600k? Mainly for gaming.. and O/T a bit..which motherboard supports sandybridge is best bang for buck? I want to do some mild OC...not heavy. Thanks again.
*
no major improvement.. different ony in HT.. gaming shud go for 4cores..
for mobo, personally i always go for asus.. p8z68 v-pro i guess?
ask others to get better recommendation biggrin.gif

Asus LLC is a lot better than Giga which has +/- 0.05v vdroop/vdrop

i had hard time to get an optimum vcore on UD7
imagine if my chip needed 1.5v to stable, i have to set 1.55v for LLC 75%.

for 24/7 OC, LLC 75% more recommended. 100% is for short term OC like short benchies only. Degradation...

agree. im having a giga board too, the voltage regulation sucks

the vcore is too high.. keep getting me errors at 51x.. tried 50x n up bclk to reach 5.1, also cant.lol


Added on September 8, 2011, 2:06 pm
47C with 1% load. your vcore is too high and I doubt you have adequate cooling capacity. Even with my setup and low ambient temp I could hit 90C on IBT, 95% ram.

If you run an IBT your PC will shutdown from thermal protection. You need to upgrade your cooling or keep it back down to 4.x ghz.

i dun thk its heat prob.. i can get 50x at 1.51v not exceeding 70c.. at 51x, real temp gives me abt 80c under load, bt got error with linx
