Q6600 core #0 @ 68 degrees!

[Teqqles]

I've a wierd problem occuring on my D-Tek FuZion cooled box(with quad nozzle), core #0 is 8 degrees (under load) warmer than the next nearest core (#1 @ 60) which in turn is a few degrees warmer than the other two. Its not really a big deal as this is stable (tested on full load for a good 8 hours) and overclocked to 3ghz, but it is scaring me off of clocking further for now. Just wondered really if any of you guys have had similar issues with an OEM chip, or if this is an issue with my setup?

I'll remount things when I can be bothered, but the rest of my project needs to be completed first :)

mostly likely a concave ihs, try lapping the cpu

Yea, worth a go, will add that to my 'to-do list' for my project, will keep you posted on how that goes (assuming I ever get my project log online ;) )

For the first 10 min of p95 core0 will run 10c hotter for me but but then they level off, 3825 stable 1.725Vcore. Core0-1 at 70C and cores2-3 at 66C.
I have an apogee gtx that is making good contact on all of the ihs and have turned it 90deg 3 times no change in temps. Dont lap the ihs if you are getting go contact, you might want to sell it later.I posted in the cooling section to see if reheating the ihs with a torh will get better contact with the ihs.

1.725 vcore?? are you nuts?

1.725 vcore?? are you nuts?

What. This mb is crazy (maxumus formula),1.725Vcore on water and the pwm is only running at 45-50C with infrared lazer no fan. I might get my 940 to 5.5G on water with this board.

PS this cpu is only to get me to the 9xxx cpus but I have had a dothan running for 2 years 24/7 at 1.6V with no probs and am still waiting to see the post that says I killed a 775 cpu with to much voltage.

I wish I had got the water cooled MB model now.

I too have a fuzion with the quad nozzle. I have a 2 and 2 split though. Ususally 6 degrees difference at idle, 4 at load. Is your quad nozzle rotated properly so that each half directs at one core? (Divider in the nozzle should be parallel with the division betweeen the cores.) Mine is, and I still get a bit of a temp spread. Could be that one core has better IHS contact, underneath.

You guys seem to reference your cores by specific #. Do you ever notice them "move around" at all? I posted somthing about it, but nobody said anything. I must be the only one. http://www.xtremesystems.org/forums/showthread.php?t=172621

I wouldn't advertise this is you ever plan on selling that chip ;) 1.7v is enough for 4.7GHz on my Q6600.. it putters at 1.35v at 3600MHz. *pats his kentsfield*

Back on topic, that is a bit unusual. Mine right nos sits at 61/58/54/54 but I think I might have too little TIM on the half of the IHS with the hotter core. Keep her under 70C though and you'll be fine :shrug:

Yea, took extra care in lining up the nozzle, I'll most likely rotate (the block) if I see that I have perfect contact when I remove the hs...

Still seems odd to me that the core partnering this is 8 degrees lower in temp after an hour of pi, surely not normal that? ;)
