Hello,
I have an AMD phenom ii x2 550BE that boots/runs just fine when bios is EC=normal ... on two different boards (gigabyte MA785GM-US2H and gigabyte 790XTA-UD4) ... I also have a phenom ii x4 965BE that boots/runs fine in either board regardless of EC being Normal or Hybrid.
with the 550BE in either board, if the EC is set to Hybrid (even with the core 2 and core 3 both disabled) the system will not load the OS ... it makes it past POST and announces itself in the initial start screen as a X4 B50 (as expected) but hangs during the OS load.
on the MA785GM-US2H with EC=hybrid and core 2 and core 3 disabled, I did get it to boot, but the OS (Ubuntu) only shows 1 CPU in the system ... when my 965BE is in the system with those settings, it shows 2 CPU's as would be expected.
Any thoughts?
