Memory Upgrade

[Ayman Altounji]

I am trying to add two 128MG DIMMS (P/N 313615-B21). I add the DIMMS to the expansion card and the system does not recognize the added memory. When the computer reboots it clocks the 131MG that is on the system board. I tried to add the DIMMS to the system board but the DIMMS do not line up properly with the system borad. I tried each of the slots on the board. Am I doing something wrong?

The part # you have posted is for 128 MB, 100 MHZ Registered ECC SDRAM. The serial # you posted has a config code of BVJ1 which indicates a 300 Mhz processor. This unit requires 60 NS EDO DIMMS and the option part # for 2 X 128 MB DIMMS is 149026-B21. The different technology prevents installing an incorrect DIMMs unless you force them.
