z800 won't boot. No video post or any video activity with 6 beeps sound pattern.
my Z800 bios ver3.6 motherboard 1.02 rev (-002 board), it doesn't boot and i have 6 beeps paterns sounds on boot, no videos nothing.
i stripped it from all PCIe cards , changed ram, changed 2 CPUs X5672 with older X5560
performed CMOS reset and PSW reset. thied other GPUs FX1800 and FX580 also a AMD HD69xx series
with no luck...
the machine was showing wiered signs before with a Tesla M2090 GPU with memory test warnings 209 errors on post on good ram dimms . i thing my latest bios config with NUMA on and Allow compute on all PCIe made this happen.
