Thank you for the updates KTE,
Nearly finished 2.8GHz benching. 2.4GHz for the NB require lots o volts to be stable. Benched 2.8/2.4 at 1.4/1.4 finaly and even there it froze one time during sandra latency test. Had no issues so far during application usage. Are you testing in CnQ tweaked mode? Tony reported an 7x ht multi helped him alot with stablilty above 3GHz, have you tried that setting?
About linux, i had no problems booting into 64bit debian testing with 32bit winxp stable settings up to 2.6GHz. During a linpack run watching the syslog i saw that some cores stopped responding in time above 2.4GHz.
Tried last week released Xen 4.1 here and it has issues detecting more than one core. The have full virtualisation support on amd platform now so i'm really curious how it will perform. Received the GTB780G mobo today. Equipped it with the 9600BE and 4x1GB G.Skills and will try that mobo now for xen testing. Seems to detect all four cores proper (at least during install right now) and without not responding timeouts. I suspect problems with apic/acpi implementations on the DFI.
Have you noticed lower power requirements from the mem? I think 2.12V was the lowest possible with the B2 at 533-5-5-5-16-18 now they run stable at ~2.0V.
