[03:26] 71% through the third pass, no errors so far. I'm planning on letting memtest86 run for at least 8 total passes. [18:43] memtest is on its sixth pass, no errors so far. [18:43] The fact that no errors have been found so far despite the memory-related errors I was getting from GNOME isn't comforting. [18:44] I'm wondering how I'd diagnose the problem if the memory checks out. [18:45] The other sources of the problem (CPU, mainboard, etc.) basically means it's time for a new computer. :-( [19:17] Ugh [19:17] It could also be that ECC is correcting the sorts of errors that Memtest is testing [19:17] Can you turn off ECC? [19:24] I don't know. I'll have to look into the BIOS after I end the current test. [20:57] No ECC options in the BIOS, just something called "Turbo Memory". [20:58] Also, something called PCI Parity. [20:58] Actually, no memory options at all. [21:03] I disabled those two items just in case and restarted the tests, this time with all 8 virtual cores active. (The previous 28 hours of testing was using a single core.) [23:40] does the chipset and bios support ECC memory? [23:53] That's a good question. Memtest is identifying the RAM as ECC, and the computer is an old Lenovo ThinkStation S20, so maybe? [23:54] I'd have to try pulling up specs for the computer to be sure. [23:58] Oh, the other amusing bit of trivia: Whoever refurbished it put DDR3-1333 ECC memory into a computer with a mainboard that only supports DDR3-1064.
