8gb only allows 4gb usable 4gb only allows 2gb usable

overclocking101 · Dec 10, 2011, 02:35 PM

so I know there are tons of threads like this but i have searched and none of the current threads have helped.

I had a 2X2GB ddr3 kit installed and it only allowed 2gb to be used, so I upgraded to a 4X2GB kit and now it only allows 4gb to be used. in bios it only shows 4gb installed, but in windows it shows 8gb installed 4 usable, cpu-z says 8gb dual channel. I have memory remap enabled, also tried disabling it and nothing. I have tried all sticks indepepndant and they work fine. I have tried reseating the cpu numerous times. I had thought it was my windows install so I did a fresh install yesterday, same issue. I have tried a different cpu thinking it was my memory controller, same problem. system is in specs, and yes it is a 64bit windows 7 ultimate install

Sounds like a BIOS problem. Do you have the most current for your mobo, or have you tried re-flashing it?

heky · Dec 10, 2011, 03:02 PM

+1 for BIOS issue. Download and flash the latest, than load CMOS defaults. Must work!

Can be caused my pushing the memory controller too far(usually the OS will show al lram ,but only 1/2 available), memory not seated correctly(common on ASUS boards that do nto have clips at both ends of teh DIMM), or CPU not seated correctly.

Can also be caused by mounting cooler too tight and flexing the board, or even just board flex from the socket.

I did recently flash to the latest bios, ill try flashing back, because for a while this issue was not present. I have reseated the cpu and memory tons in the past day still the same affect. my board has never had the socket tightening issue before, I use a venomousx with the preassure screw taken out so it uses minimal preassure. it is a board with the newer dimm slots, ill keep playeng with the memory slots as well as trying a older bios

Have fun troubleshooting, OC101!

Have you tried removing one stick to see if you have some bad slots?

yes. with lynnfeild you have to have one stick in slot 4 at all times but I checked all slots one by one otherwise and all sticks as well. all work fine

overclocking101 · Dec 14, 2011, 11:03 PM

so still nothing tomorrow im going to pull the board and try it out of the case, if that dont work im rmaing the cpu because if it isnt the board its gotta be a shit controller

overclocking101 · Dec 18, 2011, 10:34 PM

so I took the board out and with the board out of the case everything check out perfect but somehow my mobo tray is casusing the board to flex just enough to cause the socket issue. what a PITA well now I got a good excuse to tell the wife when i buy a new case!

tigger · Dec 18, 2011, 10:39 PM

Sweet, at least you figured it out, and you get to buy a new case too.
