It could be hardware related. Maybe the hardware doesn't like that memory module, or it has problems. Did you memtest+ all your memory?
Yep. Haven't ruled that out yet. I ran memtest for a weekend straight on it and it said things were cool. Someone did mention that they weren't sure memtest ran in protected mode so it may not have been able access all the ram (4G limit I guess?). I fired up memtest again after that and it listed the whole lot of ram in the stats so it would seem it must have been able to test it.
Could you try one night with the ram limited? Try ram=6912M (exclude 256MB).
There are some instances where the kernel doesn't get a correct memory mapping from the BIOS and tries to use memory it wasn't supposed to.
In my instances it only caused the system to be *very* slow, not crashes, but your case may be related.
