I talked about phenom stability. The Nb speed has an valuable impact on the memory bandwith and latency. The Core can be overclocked more with an nb speed below 2100MHz.
I asked for errata occurencies without virtualisation on the x86-64 mailing list.
There is one person who had an lockup after 1-2 days crunching. He did not have a lockup with the tlb-workaround applied.
He could reproduce the lockup so that seems to be a good testcase.
Made a kernel whom disables the bios fix without applying the workaround. Will try to reproduce his results.
1-2 days crunching ain't no quick test case. I'm curious if i can reproduce the lockup.
If so i can try the same stuff with watercooling and/or overclocking. If it's a hotspot problem the lockup should occure earlier on an overlocked system and later with watercooling.
