Solve : RAM not all showing up?

1.	Solve : RAM not all showing up?
Answer» I have just installed ANOTHER stick of DDR ram to my system but it all doesnt show up, there is 256 missing! I have 1280 in all but only 1024 shows up? I have 2 512 sticks and 1 256 stick, i know that they all work and are all fully pushed in. My mother board is a 845 pe and it will accept up to 2 GB. All of the sticks are ddr 400 and the mother board will only accept up to ddr 333 will this be the case? CheersRefer to your mainboard manual. It will tell you in what QUANTITIES you can install new RAM.
