This is the memory specs for the board: Memory - Four 184-pin DIMM sockets - Supports 2 DIMM DDR 333 (Max. 2GB) - Supports 3 DIMM Un-buffered DDR 200/266 (Max. 3GB) - Supports 4 DIMM Registered DDR 200/266 (Max. 3.5GB) Does this mean I can use 2 1GB PC2100 sticks and 2 1GB PC2700 sticks for a total of 4GB? I'm not going to use that much, but just want to know. Right now I have a 512mb and 128mb PC2100 stick, and a 256mb PC2700 stick; I'm planning on buying 1GB stick(s) of ram and just need to know what will work(I want to put the PC2100 ram in my carputer)..
