Been researching and testing for couple of weeks now and want to share my experience.
My Specs:
Intel i7-950
Gigabyte GA-X58A-UD3R rev 2.0
6GB (3x2GB GSkill F3-12800CL9T-6GBNQ)
Intel X25M G2 80GB SSD on Intel SATA2
Hitachi 1TB + Hitachi 500GB on Jmicron SATA2
All it's working at stock, even the mem is at 1066 with 7-7-7-20 timings and 1.5v
This is a shot of the mem:
I can't provide CPU-Z screens being in office on a notebook.
I had the now famous cold boot memory_management BSOD (0x1A code) for couple of weeks (after 3/4 reboots or sitting in bios screen for some time i get to the desktop, Windows 7 64bit for the record), mobo came with FB bios, i tried FC3 FC5 and FC final, but no joy, also IDE/AHCI both give BSOD. Memory and system are error free after 20 passes of memtest and system passed 8 hours OCCT and maximum Intel Burn Test.
After reading this thread yesterday evening i flashed FA bios (cleared DMI pool and loaded optimized defaults), booted into windows and i had no problems with the OS recognizing all the 6GB of ram, so no reserved ram problem for me on the FA bios which is good news already.
Rebooted and shut down/started 4 times to check mem size was always ok.
I then shut down and tried a cold boot 2 hours later, no BSOD, worked with the PC a little, did a 3DMark and 1h OCCT, no errors, then i shut down again. This morning i tried another cold boot (7 hours after the shut down) and no BSOD, did some basic surfing and an OCCT then had to come office.
PC is now shut down and i will do a 12 hours later cold boot in the evening, if it goes good i would have a 3 consecutive cold boots without BSOD record
and it would probably mean FA bios does have some mem size issue for someone but it probably solves cold boot BSODs.
Still this would leave me without words that the solution is to use an old bios
, i would really like to use the latest bios but if everything works and i can even find a stable oc later, i can live with it.
