I’ve seen this conversation all over the place, but I’ve never read a definitive answer. I’ve checked out the instructions for ASUS Sabertooth x58 motherboard and tried different physical RAM placements. (A1, B1, C1)(A1, A2; with only two cards)(A1 with only one card) and (A1, B1, C1) in a completely different computer. Each time the RAM total is as if each card only has 2GB each. Why then would Corsair put a “4GB” on the label? Why would Newegg and other places advertise them as 4GB cards if they aren’t?
I have 3 cards; each labeled -
“CMD4GX3M2A1600C9” and below that it is labeled ”4GB(2x2GB)2048MB 1600MHz 9-9-9-24”.
The mobo supports single, dual and tri-channel RAM. It supports 4GB in each of the 6 slots. The OS is running Win7Pro. The CPU has always shown 6GB RAM since it arrived. (ie, 3 cards labeled “4GB”. And one would assume that the BIOS and other operations to be up-to-date and running properly before shipping). Memory checks show no problems.
I noticed my shortage-of-RAM issue when I decided to max out my RAM for this mobo and buy 24GB. I opened the case and discovered that I could have been (or, should have been) operating with 12GB for the last 7 years instead of 6GB. I don’t want to take the chance in buying RAM labeled “4GB(2x2GB)” if I’ll only end up with 12GB. (6 slots with 2GB each).
If anyone can figure this one out I will be eternally grateful.
