The temps that you are getting are ok, what about the idle temps? Normally a cpu could withstand 95ºC top, but that's the limit, so no use on getting near there right?
Again, how are you doing with your idle temps? are you manually setting the volts or they're on auto?
You might can drop the voltage a bit. My 2600K does 4.5Ghz at 1.32v with Hyperthreading on and the 2600K usually takes a bit more juice than a 2500K because of the Hyperthreading. Temps in the upper 60s low 70s with Prime 95 are fine. What you have now at 1.35v should be safe for a long term overclock. You might just have a chip that is not quite as good just like Redeemer sounds like he got a great chip. They are all different.
Remember that core temps measured on die. When peeps talk about max cpu temps they mean temp under heatspreader, which is 8-10 C lower. Also max temp for ur cpu is 72. Ur voltage is kinda high, but it all depends on cpu batch. I'm hitting 4.7 @ 1.325
gonna try it at 1.27v now. we'll see how stable it is. because on this motherboard it seems the voltage it wants is 1.265 at 4.5ghz. how long do you recon I'd need to run prime95 to see if its stable? I don't fancy burning the cpu for like 12 hours :S
It gets onto windows. its prime95 that insta crashes it. My bios is being retarded. its showing a different voltage all the time each time i go into the tweaker tool -.- and it dosnt let me set a voltage either, theres only some voltage I cant change(which constantly changes each time i load up bios) and theres an offset.. I set the offset to 0.100 and when the bios is at 1.207 apparantly now on cpuz it shows 1.360 while running at load. this crap his unreliable -.- I shoulda left it at 1.352 because that was stable and didnt cause probs. now I've to get rid of this high voltage xD
Is it ok for it to be jumping between 1.352 and 1.36?
