Memtest on S2885 dual opteron?
A while back, someone said there was a version of the memtest program that'd been ported to AMD64... I don't suppose anyone has a link to this do they? So I can FINALLY see if it's linux itself that's having trouble, or the motherboard, with this RAM? Thanks.

I haven't followed this thread, so this might be irrelevant, but you do know that memtest86 can be fooled by ACPI [and USB?] as they write to the topmost 128kB. I was very depressed that my brand new Neo MB + Cosair DDR400 CL2 had memory error regardless of the concervative settings I used. Then when I saw the same kind of errors on a Dell server at work, I started suspecting something fishy. In both cases, disabling ACPI (as much as possible) and USB stopped memtest86 reporting memory errors, even when I cranked up the memory setting quite agressively. I can't believe that this is not mentioned on the memtest86.org site (at least I didn't see it). Regards, Tommy

Nah, this is actually about getting memtest86 to work, rather than load, start drawing the display, and reboot. I'm having incredible difficulties with kernel panics using 4gig or more and want to find out if it's a problem OUTSIDE of linux (i.e. if memtest reports errors, that proves it's the memory/motherboard combo rather than a bug in the OS itself).
