i came across some 1x4gb edgetech pc-5300 ddr2. i have a few questions about it... it just shows the "edge tech corp 4gb pc-53" on it with the barcode and serial.. but it doesnt tell you the part number ect... how can i tell if this is ecc ram FBDIMM's or is it just regular desktop ram??? im having a lot of trouble figuring this all out.
