Project: 6900 (Run 4, Clone 14, Gen 29) client core comm err
Posted: Tue Aug 16, 2011 11:07 pm
Interesting case.
I got two consecutive p6900 back to back. I just completed Project: 6900 (Run 4, Clone 14, Gen 28) - one of the fastest TPFs I have had for the P6900s too, as a matter of fact, and the next WU to load was Project: 6900 (Run 4, Clone 14, Gen 29) which terminated after 7%.
The last time I've seen this 0xc0000005 Client Core Communications Error was on July 11th (Re: Project 2686 (R9,C16,G115), with 15 bigadvs successfully completed since with no change in hardware config, O/C parameters, etc. Temps seem OK - see min/max below over several days of CPUID Hardware Monitor

And, as a reward
the next WU downloaded is a p2684!!
