Like in the New Epox Board 8KHA+ , the slots are thge same size, and the Chipset supports it, so can i put my PC133 Sdram in it and it works? Or do i need to buy DDR Sdram for it?
Nope. DDR and SDR have different pin counts and a different pin arrangement. Some boards support SDRAM and DDR, but have different slots for each type.
