I put together a 2600k system built on an Asrock Z68 Extreme 4 Gen 3 board with 16gb of Gskill PC12800CL9D-8GBRL sticks. However I have yet to get it running correctly with all 4 sticks of memory. The motherboard has the latest bios, all drivers are updated and Win 7 Ultimate 64bit has service pack 1 and all updates, but the system will BSOD within minutes of booting to windows, no matter what settings I use on the memory and no matter how much load I have on the memory or CPU. I have tried switching sticks around, (system runs great with memory in slots 2 and 4 or 1 and 3), but NOT with sticks in all 4 slots. I have run memtest on all 4 sticks and they check out fine as well as switching them out randomly so I'm relatively sure all the sticks are good. This system runs all day at 4.8Ghz, (with only 2 sticks of ram in) and folds pretty much 24/7, the only break it gets is when I play BF3 at night. These are the things I've done so far trying to fix this problem.
1. updated motherboard bios
2. Bios settings, played with VCCSA voltage, (set from auto, .925v, 1.016v, 1.107v and 1.2v) None of these settings work with 4 sticks in and the motherboard doesn't seem to care what the settings are with 2 sticks in, they all work fine as long as only 2 sticks are in.
3. VTT Voltage in Bios: auto, 1.051v, 1.103v, 1.155v, none make any difference.
4. manually set memory timings in bios as well as trying it on auto, again it makes no difference, I get a BSOD in windows within minutes of booting.
5. Doing all this in the last 3 hours, all the bios settings we're purely stock, (no overclock on the CPU or motherboard) as well as trying it all with my 4.6Ghz and 4.8Ghz overclock settings.
6. Adjusted memory voltage, (auto, 1.5v, 1.55v, 1.6v) makes no difference.
BSOD errors I usually get, (again these seem random and I never get the same one twice in a row)
0x050
0x7E
0x9C
0x1A
0x1E
From what I can tell, most of these have to do with the VTT voltage, VCCSA voltage, Vcore or memory timings. Again, It makes no difference if the PC is overclocked or everything is bone stock.
Pretty much at the end of my chain here, I have no idea what else to try....
