I got new RAM for my sig machine today: Corsair Vengeance 2x8GB for a total of 16GB (mobo is mini-ITX has two slots).
I swap it out, run memtest. Lots of Errors.
Go to BIOS. I had set the timings manually: 9-9-9-24. New ram is same speed (DDR3-1600) but rated 10-10-10-27.
Update manual timing settings to 10-10-10-27.
Run memtest. No errors after an hour. Entire pass completes. Looking good. Think I'm going to leave it overnight and it'll still be good when I wake up.
At some short amount of time after that, the screen goes black. I have the monitor connected to the computer via the VGA port on the motherboard: The Intel integrated HD2000. It's not entirely black. There is this slight noise/fuzz at the top left corner. I made a video recording of what it looks like. http://www.youtube.com/watch?v=T8rP03TsXCU
Memtest86 seems to still be running. I cannot see the screen though so I do not know if there are now errors. However, pressing Esc does quit the program: So it did not hang.
You see, what's so frustrating about this setup I've got is that it is so incredibly cramped that the large heatspreaders on this ram actually interferes (1-2mm) with one of the heatsink's fluid pipes. The pipe not being flexible, this requires me to dremel off a bit of the heatspreader.
Now I wouldn't want to do that unless I was sure the RAM is solid and I won't need to RMA it. So I unbolted the HSF radiator so that the sticks could be installed.
And now I get this strangeness in memtest86.
Has anybody ever seen this happen?
What does this mean? I'm going to boot into windows and I guess I will run Prime95 on Blend for a while and post back with results.
Update: Prime95 Blend seemed to have caused a reboot about 10 minutes in. I had my back turned to the computer. It reboots so damn fast. This sucks.
Maybe I could find the command rate and set that to 2T and give it a try...
