The first time I put the system together it wouldn't post. The 4 LED's indicated a memory installation error. I had the two memory sticks installed in slots 1 and 3 for dual-channel operation. I re-inserted the memory several times with the same problem. Finally I removed the stick from slot 3 and it booted fine.
Next I tried swapping the sticks, thinking maybe one was bad. The machine boots fine with one stick in slot 1, but will not boot if I put the second one in slot 3.
Placing the second stick in slot 2 allows me to boot also, and I have all 2 GB of RAM, but only single channel. Additionally, the mobo will only run the memory at 5-5-5-18 timings using SPD. If I manually change it to 4-4-4-12 it will not boot, even it I up the Vdimm to 2.1V as Corsair recommends.
With a single mem stick I can run at 4-4-4-12, but not with both.
Memtest 86+ ran for 6 hours with no problems. I have the latest BIOS version installed.
So, to summarize:
- cannot run dual channel (doesn't work with slots 2/4 either)
- can't run at rated timings with 2 GB, only with 1 GB
