hey guys im relatively new to this so please bear with me.
I have a asus p6T motherboard, with intel i7 930 at 2.8ghz. 6gb of ram and a nvidia gts250 1gb graphics card.
the problem i am having is everytime i boot my pc it says different ammounts of ram, either the full 6gb, or 4gb. it says this on both wes and cpu-z .
i have tried looking for a bios update the only ones i can find and have tried regarding memory i get the message of - selected rom file is older than existing. could it be any other issue? i have 6gb of corsair 1600mhz ram.
