So, instead of R4E or EX9, I will use the MSI X79A-GD65 8D board with the new 1.7b2 bios. So far, testing is going ok.
Notes:
- DDR3-2300+ needs 2T timing; DDR3-2400 1T will not boot
- C9-11-11 timings can be pushed to ~ DDR3-2520
- C10-12-12 timings can be pushed to ~ DDR3-2610
- board hits a hard wall at 122,5MHz BCLK with 1300+ memory (needs bios solution)
Apart from that, the kit looks fairly nice. Some screenshots:
DDR3-2610 was fully stable with Ycruncher. I used a custom setting to allocate as much memory as possible; in the test 15GB was being used by the benchmark. Adding another 0.125MHz BCLK made the system freeze instantly ... so much be a bios bug.
By the way, this GD65 8D seems rather fine! 16GB DDR3-2600 with 162MHz BCLK
