Second kit came back clean too, but when all used together it errors. A quick Google suggests 4 dimms + gigabyte z87 = bsod.
Runs fine at 2133 on my MSI Z87M-G43
May have to tweak, would randomly restart computer, had set it to Profile one for XMP, runs fine on Profile 2.
Well I've got 16GB working @ no overclock, 1333MHz speed
Attempting to deviate from that gives many results on the theme of "nope"
Previous memory was 4x2 @ 1600MHz on a 4GHz OC
Back to the bios!
Bit worrying as PGI is having issues as well, hope it's a one off so to speak, rather than poor ram?
Some CPUs don't like higher speed RAM, my computer would occasionally crash when I had 2400MHz Trident-X RAM but worked fine at 2133MHz. I error checked the RAM multiple times to ensure that wasn't the problem. I'm not able to try my kits until next week but I realise I may have to run it at 2133 to get it to work properly. At this price though I'm still happy
So yours isn't working either! Great
