I have an Asus M4A785-M which is AM3 with DDR2. I recently tried to upgrade its memory from 8gb to 16gb and am running into problems with various memory testers (eg memtest86+). Maybe some of you hardware grandpas have some wisdom to share.
The configuration is just the mobo, phenom II 960T (4x), various mem configurations, no other hardware. Firmware is latest, v1101 - no mention of 16gb limitation or fixes in documentation or bios patches.

Observations:
- the exact samsung sticks are in the "tested" list per Asus
- configurations that work: 4x2gb, 2x4gb + 2x2gb
- configurations that do not work in any arrangement: 4x4gb
- all sticks tested individually - ok
- each slot tested individually - ok
- default memory settings in BIOS
- tried a variety of dual channel and interleaving settings - no obvious effect
