Anyway, CoreTemp is reporting that cores 1 & 2 are 5 degrees hotter than 3 & 4. Is this normal? It's not too big of a deal, my absolute max temperatures never hit 60 on the hotter cores, but it's a bit strange to me. And yes, the grease was applied evenly, though I'm open to the possibility that it might've slid around a bit.

5 degrees would be a bit more variance than what I would like between the cores. Try remounting.

Im with a Tuniq Tower and a G0 Q6600 myself and the difference between cores is fluctuates in Core Temp by no more than 2c.


Also the G0 steppings are good for 72c just so you know.

Nice rig, but your loop has way too many right angles. Those really impede water flow.

Thanks for the reply, I'll give it a couple of days for the grease to cure and see what happens (using the Zalman Super Thermal that came with the cooler). If it doesn't even out, I'll remount. I won't be pushing the processor much further than it is; I just wanted it to be 2x as fast as my old 4800+ on a single core.

Also, I'm still having difficulties with stability. I've been ratcheting up the vcore from whatever the stock was, all the way to 1.350, and I still get one core failing Prime (quad version, blend test) within 2 test cycles. Seems to be a memory error now, so maybe I'll have to clock that down a bit (stupid p5e-do-vm won't go higher than 2.1v, memory is rated at 2.2-2.3, and multiplier won't go over 10 in bios).

1.350vc is nothing. I have my G0 Q6600 at 1.50vc at 3.5ghz and thats on air. P95 stable.

Got mine at 3.33GHz with 1.35v ... idle is around 35c ... prime95 Small FFTs load is around 55c - 60c ... i could push it alot higher ... i just dont see the point yet! ... it eats everything in its path!

Yeah there isnt much of a point past 3.3ghz. I used to run mine at 3.5ghz but settled for a nice comfy 3.4ghz with 1.4vc.

Likewise with me at 3.4ghz, considering what I paid for this chip, and considering how much that kind of performance would cost out of the box. I'm happy.

I also have the Abit board and I'm running at 1.44V. The Abit board suffers from vdroop quite badly. Under Prime95 load it will drop to 1.41V.

My new OC on a 780i 5 hour +



I could only get 3.6 on a 680i stable for 4 hours

how are the temps? Air or water? I can get 3.8 on my 6600 with water, but only do 3.6 as i dont have to use near as much voltages.

Its on water, I don't even look at temps as theres nothing I really trust , plus I'm using Vista 64 which makes even harder to monitor them.
