Just picked up aOptiplex 745 with 2 ram slots. specs list 533 or 667MHz ( 2 X 512M DDR 2 1RX8 5300u-555-12 @ the moment) and have been told at one store & seen a couple of articles suggesting DDR 2 800 will work.
IS any one able to confirm this and would I have to make bios changes, if I do then I'll just go with 2 X2G 667. I am not really fussed if it does or not but 800 is easier to get locally but will get off Ebay in either format if necessary.
thank you all you techies
