New Overclock temperatures worries

[DXStriker]

I just got my new build together
Core i7 920 (D0)
Asus P6T
XFX 5850
Haf922
Gskill 6 gb 1600mhz
Noctua NH14
Corsair 750W
Windows 7

My bios was a little different then what i was reading but i went into AI Tweaking.
Then set my BCLK Freq to 175
Left everything else auto up there except my Ram was 1447 mhz

Then i put my vcore 1.35
and my Dramm 2.24

I just ran Prime95 for 12 hours and my Temperatures are staying steady at 70-75 % C at 100 % load
Idle was 35-40 C

I am wondering if i am doing something wrong or left something out .
Or are these Temperatures safe??

Yep those temperatures are fine. Its not until you get into the high 70s, low 80s (and higher) all the time at 100% that you should start to worry as you'll degrade your chip from its 20ish year life span down a few to several years. I fold 24/7 on mine (aka 100% load 24/7) and i don't like seeming mine over 75C constant, with my current set up (on air and a C0/C1) i can keep it down around in the 60s. But i'm happy folding around 70C too.

1.35Vcore is high for a D0 @ 3.5Ghz.
And if they are not dead yet, drop the Vram NOW to 1.5V, 1.65 MAX.

i typoed that for dramm voltage lol its at 1.64

anyway thanks for replies =)

Imma try bringing the cpu voltage down to 1.30

Use OCCT, Custom 30 minutes - it's faster, and will tell you if your OC is stable or not.

You're perfect fine if those are diode temps (DTS readings) and not CPU temp (TCase).
Use RealTemp put HT on and run 30 minutes of prime95 Large FFTs. If you're under 80°C on cores you're OK in daily use.

Ya i'm no expert on this, but I have a very similar setup and was able to get a conservative 3.8 GHz with 1.20 Volts no problem...



My temps also range in the high 60's, low 70's under full load.

looking good to me
