Not sure if you're still looking for additional cases to submit to ASUS/nVIDIA/etc, but I am exhibiting similar issues to the ones logged here.
Xeon E5-2687W ES (QA91) x 2Cooling
Corsair H80i x 2Motherboard
ASUS Z9PE-D8 WSBIOS
Samsung SSD 256GB 840 PRO SeriesRAM
Corsair Vengeance 32GB 4x8GB DIMMGPU
Galaxy GTX 460 (768MB DDR5)PSU
Cooler Master Cosmos IIOS
Windoze 7 Ultimate
At first I was working with a single CPU and a 32GB RAM kit. The RAM was detected by the system while in a single CPU configuration. However my H80i was screwed on too tightly it would seem, as loosening it appears to have greatly decreased BSODs, although yesterday I seemed to generate the same ugly nVIDIA driver drops that plagued the board prior to loosening the cooling bracket.
While the CPU was screwed in too tightly, I attempted to boot the system with the following GPUs without success in PCIe slots 1 and 3:
2 x 2GB DDR5 GTX 670 by MSI
1 x 2GB DDR5 GTX 680 by eVGA
Once I had unloosened the screws I attempted the same with the:
1x 4GB DDR5 GTX 670 by eVGA
Despite this chip failing to register with my u3011 monitor, Q-code appears in the same/similar to those appearing when I use a Galaxy GTX 460 in PCIe slot 3, (ultimately 62 and then 15 which persists). Additionally, it appears that the OS is booting because when I added an external speaker to the motherboard I could hear the Windows prompt. I'll note that I haven't installed the onboard speaker, although that would likely help in diagnosing the problem. I'm yet unsure whether or not the problem is with the GPU, the board, or the nVIDIA driver.
This morning, (admittedly against the advice of this forum) I installed a second QA91 that appears to now be playing nicely with the CPU I had already installed and the Galaxy GTX 460. However now CPU-Z and Windoze are only seeing 24GB of RAM. I'll attempt reseating/moving them around, then I'll check to see if the BIOS is detecting the sticks a little later.
Perhaps a more important update is that I finally got a 600 series GPU to work with the board:
1x 4GB DDR5 GTX 670 by eVGA
The GPU worked fine out of the DVI-D, or DVI-I output (I can't recall which one) although it reduced the resolution to like 1600xwhatever. This was fixed with a simple nVIDIA driver update to 314.22. The GPU is seated in PCIe slot 3 and is the only GPU installed at the moment, (I will likely add a second card later). Has anyone else had success with this configuration already?
More importantly has anyone had success SLIing Titans with this board yet?
Unfortunately the RAM problem persists. Will likely return the Vengeance 32GB kit and purchase a 64GB kit at a higher clock speed, (so I can hopefully achieve 1600). Any recommendations?Edited by baishikui - 4/6/13 at 1:21pm
