E8400 @ 3.6 GHZ with 1.152 V?

and LLC is fine at these voltages it only when you get really high that you need to disable it on asus boards. jmo. Gigabyte boards on the other hand i leave it on all the time ( and yes i know what vdroop is )

EDIT nice overclock by the way

Will running a 12h test at roughly 66-71C cause any harm to my CPU? Getting ready to start an overnight small FFT test. Real temp says Thermal status: OK, but Id just like to make sure.

[gingerbee]

I would be fine with those temps

Considering the thermal spec for that cpu is 72.4 I reckon running at 71 isn't a good idea. You really need to improve your cooling before you break something. Your performance will decrease as temperatures increase.

My thermal spec is 62c But I don't come within 10c of that loaded or idle... and thats at 1.57volts.

Thermal spec doesn't mean max temp under load.

I pushed my 8400 to 80 quite often with no adverse effects.

From what I read, 72C is the Tcase value? Where 105C is the max value for each individual core. My overall CPU temp is 59 under full load, which is the temp that corresponds to the 72.4 limit. Anyway, test is at 7 hours now, no errors yet. *knock on wood* :P

this is for the IHS not the core get the gauges and work out your delta if you must I have on corei7's and c2d ( I can tell you from personal experience the c2d delta is any where from 5c to 10c at max tdp. So playing it safe then you still have some room even with a 5c delta your ihs is only 64c lots of room read the pdf white pages there lots they won't tell people ( core speed now has a lot to do with cooler effectiveness )

test prime 1 hour max
best test is games
you can run prime for 24 hours and still crash in game ;)
1.4v is safe as long as temps are below 70c
you should try n see if you can hit 4.0 with 1.25v-1.3v
hope you have a good heatsink lol

[Fayth]

Ill be trying to push it further when I get my hands on a new heatsink. For now, its on stock so im happy with 3.6GHZ. Posting from school atm, left the Prime95 test going at home. I have already tested it in game with no issues, but I didnt see any harm in running a 12-16 hour test while I wouldnt have been on the computer anyway. In any case, thanks for all the help guys.

Ah good to know... thanks champ.
