Sabertooth X79; 32 MB Corsair RAM (4 x 8Gb set); Windows 7 Profession, 64 bit. Only 24 MB are recognized. Sabertooth setup/diagnostic screen indicates that DIMM 1 location is not working properly. I swapped memory modules and it's still the same DIMM 1 location with the problem. It appears that the issue is not the memory itself but the motherboard. Any suggestions?
Have you tried using the other 4 dimm slots to rule out a bad dimm slot?
Try updating your bios.
I swapped memory modules around, it's always the same DIMM slot that comes up as "abnormal".
If you have another set of ram sticks then put it in your mobo after that look for DIMM solt working condition using diagnostic is it getting problem again with another sticks [incase you only have one stick and if you know which slot got problem put that stick in that slot if dont know try that stick with each solt @ time] If still goes same check out the stick inserted correctly or not
