Just wondered if this sounds familier to anyone. I've just been helping a friend trouble shoot his new rig, specs as follows:
X2 4200+
Zalman CNPS7700-ALCU
Asus A8N-SLi SE nForce4 SLi (I think)
2x1GB Corsair XMS (not matched, from old machine)
2xGainward 7900GT's
2xSeagate baracuda 250GB
Plenty of case fans.

Yes I know he should probably bought an Opteron and an ATI card especially as his TFT only displays 1280x1024 but he daftly didn't take the time to consult me first. Rant over, the problem is that his CPU was quickly climbing upto 75 degrees where upon we decided to switch it off. After taking the Zalman off and re-applying and proper thin and even layer of AS5 and re-fitting the cooler we still had the same problem abeit much slower taking maybe 15mins to get to 70c instead of 4. I then knocked the Vcore down to 1.32 and then to 1.21 and we are still having the same problem. The heat just builds up very slowing but just as surely.

I have been using prime95 on one core and ATI Tool on the other for stress testing purposes.

I can only think that the problem could be with the IHS and not having been applied properly in the factory causing this slow build up of heat.

Anyone have and ideas as I'mn pretty much out??

Thanks in advanced.

Yeah, I did think it could just be a faulty motherboard but prime fails at about 70-77c depending on voltage.

You think my heat spreader theory might have some ground?
 
Idle temps about 45-46 ish, but it does stabilize about there.
And my little sempron idles at about 33-34 and thats with 1.575v, a 1Ghz overclock and a similare cooler.
 
He has a venice 3000+ which I've told him to try. He'll probably get back to me today so I'm expecting it to be fine.

Also with it running at 1.2v it's getting to about 46-47 on full load but something's obviously not right and he's forked out nearly £1100 on a new system so he might as well make sure it's proper eh?
 
Yep, as suspected the venice is cool (pun intended, sic). Should I tell him to get an Opteron 165? He's using an Asus A8N-SLI deluxe. Does that do very high HTT speeds?
 
Hyper transport is just so under saturated that it's just better to keep it in spec and stable.

Imagine the M25 with 100 lanes, not much point in adding another 10 is there?
 
Right, he's sending the 4200+ back and getting a 165. He's tested his mobo at 313 HTT and it's plenty stable so I thin he should be chuffed with the end result eh?
