Re: Strange system behavior

What memory do you have ? Does it match the motherboard specification ?

Memory was my first suspicion.  I started with 2x2GB of Kingston memory:

spdmem2: DDR3 SDRAM, no ECC, no temp-sensor, 2GB, 1333MHz (PC3-10666)
spdmem2: 11 rows, 13 cols, 8 log. banks, 2 phys. banks, 1.500ns cycle time
spdmem2: tAA-tRCD-tRP-tRAS: 9-9-9-24


When the problems first manifested, I replaced that with 2x2GB from
Corsair:

spdmem1: DDR3 SDRAM, no ECC, no temp-sensor, 2GB, 1333MHz (PC3-10666)
spdmem1: 12 rows, 13 cols, 8 log. banks, 1 phys. banks, 1.500ns cycle time
spdmem1: tAA-tRCD-tRP-tRAS: 8-8-8-24

Hum, asus says for the M4A88T-M
"AMD AM3 100 and 200 series CPU support up to DDR3 1066MHz"

while for the M4A88TD-M EVO/USB3
"Due to CPU spec., AMD 100 and 200 series CPUs support up to DDR3 1066Mhz.
With ASUS design, this motherboard can support up to DDR3 1333MHz"

so there is a difference between the working and non-working motherboard
in this area.
Did you try with 1066MHz memory, or to lower the memory speed in
the bios (if this is possible, I don't know) ?

I did see that note, but I just assumed that "100 and 200 series" would refer to older CPUs, and that the restriction wouldn't apply to newer, top-of-the-line models!

The BIOS does have a "DRAM Frequency" option, with values of 800, 1067, 1333, and 1600 MHz. I'll give it a try and see if it helps.
