what you guys think about so high temperatures on overclocked C2D ? 70C with single Prime ? come on... these cpus will die pretty soon... run dual prime and it will be as high as 80C.

ps. im not talking about just o/c to check it out, accepting the risk. but some ppl say that would be 24/7 config for them, this is what amuses me.

[Jodiuh]

I've always preferred to take them as far as stock vcore will go. It's never seemed worth the jump for 5-10% more speed IMO. Of course that won't stop me if temps are reasonable.

Anyone know about week 23 is any good?

I still dont' know where the temp cutoff is for these cores, mine hits 59-60C under heavy load. I will call intel i guess and ask them.

[Jodiuh]

Haha, so true. I hear 61.3, 60, and then see some folks hitting 67. I guess one way to find out would be using throttle watch.

[yury2808]

Jodiuh+Artmic: and you have to remember, that 60-65C you see in BIOS/MB utility could be around 15C lower that real cpu temperature... since some MB get these from undersocket sensor.

[alpha0ne]

The most I have seen my temps get to is 58C @ 4.0GHz, I have now settled for my 24/7 settup of 3.4GHz with max temps of only 44C using 1.3125Vcore

Eeek double post sorry.

Scythe Ninja, Max temps @ 47'C I haven't found the max clocks yet but I'm pretty happy so far.

I have no idea, i hit 72C on both cores on Everest. with Orthos.
I freaked out lol now my temps go up to 60C maximum, i will get one more panaflo for the side panel and hopefully i will run cool from then on.

Heres my best with my week 26 E6300 OEM. The DS3 mobo is definately the limiting factor for me now, Memory i was using is OCZ Gold Edition 6400 at 5-5-5-10. Think i am gonna get rid of the CPU and Memory and try something else.

[yury2808]

Artmic: "I have no idea, i hit 72C on both cores on Everest" - go on www.rightmark.org and get the RMClock utility, it will show you the internal thermal sensor of cpu. you will be surprised...

ps. i hear alot of "warning" messages lately from ppl who o/c their processors (mean C2D on 965 based mobos, which usually treat only near-by-socket thermal sensor) and couple weeks after heavy usage they got problems. remember, 85C seem to be final limit for the core itself, will ya check how hot it is in REALITY ? I would.

E6400 L625, Scythe Ninja, P5B DLX 3.21 GHZ 1.29V. Did the same with Gigabyte DQ6 @1.28V, but I don't have a screenie. That's quite a good chip. Didn't try higher voltage.

MVP JOR: under dual prime CPU temperature can't be 41C (and ofc not 30C) with air cooling... Speedfan seem to read it wrong, try another utility, like Intel Thermal Analysis Tool (TAT) or something... it have to be around 60C. here is my 2.8 config to be 24/7:

[Jodiuh]

Yeah, my DS3's system temp hovers between 38-41. It'll sky towards 50 when gaming. Blame the Accelero for that...

[BAR*B*Q]

hey m8's - my first post here

@ alpha0ne
hehe... 1 ghz oc @ stock is appropriate

which week ?

1.7V on Air! You're nuts!! How are temps?

i buy it at taiwan.

Well, I lapped my E6700 (see first post on page 13).

Results are amazing. I dropped roughly 12 C on my custom water. I didn't lap to a mirror finish, just some ghetto 600 grit from Home Hardware. Went 120 -> 220 -> 320 -> 400 -> 600. Some wet, mostly dry... it did go a lot faster, however the metal dust accumulated everywhere hehe.

Currently can get into windows 360 x 10 @ 1.500 vCore with a Big Typhoon. Orthos unstable.. unsure of Core Temp.
Stress testing Orthos Small FFTs 360 x 10 @ 1.5000 vCore on water with 63 C peak temp in Core Temp, 48 C in Speedfan.
Need more voltage for 370 x 10... not sure how much yet.

I will post pics and some more details later....

My problem now is trying to get my motherboard stable... I have very poor contact with the stock P5WDH NB/MOSFET sink, half of the NB was barely touching. I replaced it with a Zalman ZM-NBF47 and a 120mm fan sitting on top of it and the RAM.... Running lowest RAM divider with RAM @ SPD.. how depressing.

EDIT:
370 x 10 and 375 x 10 relatively stable @ 1.55 vCore

Currently testing 360 x 10 @ 1.48xxx vCore (Fails at 1.475 after some minutes). I have a feeling it's because of vdroop.
This board ... argh... frustrating! Even more than my AOpen i975 !!!!
