SDRAM Information

Shape and Size

SDRAM is built in many different ways and may not always look exactly like the photo above. This means the IC chips (the black rectangles) may be a different size or shape or arranged differently. The main thing to look for is the notches, length (5.25") and height (1.37"). The length will always be 5.25 but some machines may require a shorter height than 1.37". Again, this is yet another reason to use our configurator.

Pin Count

SDRAM has 168 pins with 2 notches. It shouldn't be confused with DDR RAM which has 184 pins and only 1 notch. If you need help finding the correct RAM, see our configurator to start the process of getting 100% compatible RAM with free shipping included!

More Technical Details

Short for Synchronous DRAM, a type of DRAM that can run at much higher clock speeds than conventional memory. SDRAM actually synchronizes itself with the CPU's bus.
