Andreas,

The FCPGA 1.0 GHz P3s (Socket 370) are only manufactured in cC0 stepping and function up to 70°C.

Ok, that explains it. It's not as bad as the 60C. Where did you find out this info? I couldn't find very much on cC0 stepping. I thought that the complete cC0 stepping was recalled with Piii 1.13 GHz. I guess it's just a further proof that cC0 was not broken, it was just overclocked by Intel way beyond it's safety margin.

The sad thing is that the folks here are willing to just religiously follow the Intel PR statements without thinking for themselves. They argue that 60C is fine, while clearly it's a joke.

Joe

The FCPGA 1.0 GHz P3s (Socket 370) are only manufactured in cC0 stepping and function up to 70°C. The older ones in Slot package (cB0 stepping) had a maximum temperature tolerance of 60°C. The (recalled) 1.13 GHz P3 were also in cC0 stepping and had a temperature tolerance of 62°C. All P3s with cC0 stepping are SMP capable. Before the cC0 stepping binsplits must have been really terrible (i.e. <1%). With the new stepping availability has somewhat improved, there are already 25 Pricewatch vendors selling them. However, still no vendor in Germany has them available.

This has been my interpretation as well. Also, in my opinion, the 1.13GHz part was a cC0 stepping (14% shrink) which was bumped to 1.8V and also was at the extreme short end of the channel length distribution. See:
