Mick, you’re dead on regarding the cheap feel to these parts. After repeated failures, we’ve gained a sure knowledge of that as well.

The circle on the chip was caused after the thing on the chip formed. Obviously, that caused terrible contact with the surface. Prior to that, we had cleaned the CPU and found no evidence of poor connectivity like that, so the “cancer” was the cause of it. That said, the grease was laid on a bit heavy for my taste.

I personally have never had a problem with model/stepping-level differences, so I wouldn’t consider it essential. It is, however, bad form if nothing else. It’s probably more of an issue in multi-cpu (not multi-core) setups, which I’ve not dealt with extensively.

When our heat sink properly connects, we also enjoy the cool core temps you mentioned, which is quite nice. Was that for your woodcrest/conroe setup, or your amd gear?
