Kind of an open question I know. But how many passes with memtest86+ is generally considered to be enough to show memory as good?
Here's my situation: I have F3-8500CL7Q-16GBRL on a M4A785TD-M EVO. All hardware purchased new in Jan 2011.
I run ESXi on this box and had at least two virtual servers running, sometimes three. Never exceeded the total physical memory. About 2 weeks ago I started crashing and having problems booting. Also noticed that my BIOS settings were not "sticking", i.e., I would set the system to boot from USB, but it wouldn't find it. Located and ran memtest86+ and it showed errors in the upper memory ranges.
Replaced CMOS battery (which seemed to solve the BIOS setting sticking issue) but was still having problems booting and crashing. Ran memtest86+, again showing errors but now all over the memory range.
Folks at support suggested I test each stick individually, which I have been doing since yesterday. I let one stick run 10 passes for almost 9 hours. Another stick I let run for 5 passes for just over 4 hours. 3rd stick has now been testing for almost 4 hours.
So as the topic asks, "Am I letting these run diags log enough?" If they make it through 1 pass, is that enough to declare the stick good? I am not moving sticks around in the mb slots. In other words, I found one slot that would let me boot and that's the slot all the testing is being done with.
BTW, had to change CAS to 7-7-7-18 which seemed to make a big difference. Have not changed voltage--yet. Should I once I get all four sticks back in? and if so, by how much?
Sorry for the long post and TIA for any help.
