Motherboard: GIGABYTE GA-X58A-UD3R
CPU: Intel Core i7-920 Bloomfield 2.66GHz
Memory: F3-16000CL9T-6GBTD
Power: 900W Supermicro
GIGABYTE's compatibility chart for this motherboard cites this memory as working in triple channel: http://www.gigabyte.us/FileList/Memo...-x58a-ud3r.pdf
When I populate the board in triple channel (3 DIMMs in the blue slots) the machine will not post. This is with the default BIOS settings; it does not enable the XMP profile by default.
Configured as dual channel using only two of the DIMMs I am able to boot the machine. I had trouble getting the bios to recognize one of the DIMMs. The BIOS would only see a total of 2GB even though CPU-Z would show both DIMMs present. I swapped out the second DIMM and the BIOS saw all 4GB.
I started with the default BIOS configuration then changed to the XMP memory profile.
I ran like this successfully with 4GB in dual channel for several days with a Vertex Turbo 60GB SSD and a 3ware 9690SA PCI-E card in the system.
After a few days I experienced major stability problems that seemed to be memory related (BSOD with IRQL_NOT_LESS_OR_EQUAL, hangs, etc). I set BIOS "Performance Enhance" to Standard (did not improve stability). Then I tweaked the DIMM voltage up to 1.64 and have been running stable again for several days.
My major questions are:
1) Do you have a set of recommended timings/voltages for this RAM in this MB? I tried some settings you posted for other GIGABYTE MBs but my system would not post with them in dual channel.
2) What do you recommend I do to debug problem not posting at all in triple channel?
3) Does it make sense that the XMP profile default settings were unstable and I had to tweak the DIMM voltage up?
