Nop. Coz i'd reached 100C with 1.35V @4.10 GHZ .. no problem... this is IBT stress. So the temperature is higher. During Prime95 the temperature @80C+ full load
Anyway, i wouldnt recommend anyone running their proc with the temperature that high daily either.

Note: That overclocking attempt... It's not rock solid stable. Trust me. Passed 25 loops IBT and prime95 small fft for 3hours but failed prime95 mid~large FFT (blend) within 3 minutes.
Probably need extra vmem and vnb and couple of tweaks.... will attempt to make it stable if i have a time to do it....
The only rock solid stable clock for my processor w/ P5Q Deluxe is @3.70GHz which is the sweet spot (less vcore/low FSB/low load temp @80C IBT/super rock stable) of the proc. Running 24/7 now.

Relax dude... just don't give up. Your ASUS M2F is a good motherboard.... Give a bit more try(depend on your OCing skill)...  I'm sure you will reach your targeted clock (of course it must be realistic clock).

As long as it is running @ 775 socket. Then should be fine.

-pWs-

so p35ds3r can run without hassle?

wow.. great..

whats ur temp?? isit crazily hot? wat cooler u using btw??

WOW..

rite now my system cant do that..dunnoe why..
last time tried 4.01Ghz but after that cant reach it at all..
no just set to Auto (15%) in bios.. running 2.83-3.3Ghz

Higher vcore is needed to pass IBT longer... you may pass Prime95 small FFT with low vcore but can't pass IBT.... Hope that answer your Q.

it is consider quasi-stable not rock solid stable..... probably u will encounter instability when running CPU+Mem intensive application...
My personal ref... rock solid stable means u must passed IBT/Prime95(small/mid/large)/OCCT test(small/mid/large) with 99% mem utilized...

Even if u passed 20 loops IBT, probably u can't pass Prime95 mid/large FFT.... three of tests are needed to ensure rock solid stable operation...

If u have time... test again with multi x8.5...
Make sure that ur next screenies include Asus Probe and Memset r displayed together... better...

Oh OK.. U didn't mention you were running the proc with EIST...
For your next stability test.. run prime95.. select custom.. set the FFT min and max 4096.. time to run each test set to 60 minutes... and run it for 2 hours...
n i'm pretty sure if u pass this test, u can enjoy almost rock solid stable computer... and of course you must pass IBT test as well...

Nice OC.. Now u can enjoy fast n stable computer.... also u need watch out your temps esp the CPU...
btw... i suspect my RAM got problem... supposely it doesn't need vmem that high to stabilise it @ 566MHzX2... 
will update u guys later...

UPDATE:
As i suspected.. one of my RAM sticks failed.... 
and i believe it failed not because of i ramped the it at 2.3V... because i never run it beyond 2.3V before and just ran/stressed it for few hours recently...
I suspected when i started to ramp vmem at 2.14V and stress it couple of hours (3~4 hours) during my 1st overclocking attempt at 4GHz.
I reverted back to stock before attempting 2nd overclocking. In between 1st OC attempt n OC 2nd attempt... i encountered minor crashes for 2~3 times or maybe more(specifically windows internet explorer or explorer)..oh ok... i thought it might some kind of application glitches because at that time i was installing ACDSee .. and think the application could be the problem....  Now it is proven that the RAM failed because of mild overvolt from recommended voltage.... fyi, recommended voltage for my RAM sticks is 2.1V @ 4-4-4-12@800MHz...

Fortunately, some broken RAM sticks could be revived..

For ppl who interested.. they can view here.... http://www.xtremesystems.org/forums/showth...t=205009&page=6

I'm trying to revive the RAM stick using freezing technique... already in the freezer n waiting for miracle... hopefully it will work for my RAM... 

@kilowatt
Put a decent cooling fan for your RAM if u want to run at 2.2V 24/7....

Anyone here using DFI P35 Blood iron . . ?

My Q9450 cant get above 440 FSB .

Vcore - 1.55
VTT - 1.36
VPLL - 1.55
Vsb - 1.95
Vnb - 1.46
Vclockgen( Wth is this ? ) - 3.55 default.

All GTL at 0.67x

I get tips from other forum to up my VTT and VNB if i want to get higher clock . But why my board got Vclockgen and Vsb ? What value is optimum ?

Hi guys, I am running Q9550, E0. Just got this last week. I was wondering, I have set Vcore 1.2V and pumped up to 3.3Ghz. Is 1.2V consider as stock voltage and mere 3.3Ghz is safe to be used?
