I have a DFI AK 70 Slot a board. Almost every day I have reinstall the memory. It takes about 10 installations of practically hammering them in. The tabs snap shut and all but half the time they still don't make contact. Its not any particular module, its the mobo thats so damn tight. I'm getting sick and tired of opening my case every day to reinstall them. Its like they loosen themselves everyday on their own. Any harder pushing them in and I'll probably break them or the board! Does anyone have any suggestions as to what I can do if anything?
