Purchased two more matched sticks of (new PQI)512 memory for my machine to upgrade my RAM capacity... (trying to end up with 1.5G... 3 slots at 512 each)
already had .750G, took out the 256K stick, put in the two new sticks and nada... damn thing won't come up.
took out one 512 stick and all works fine, just won't work when all three sticks are installed. Tried all the different combinations and locations with all four sticks (512, 512, 512, 256,) and three sockets on the motherboard, can't get it to work with over a Gig of RAM.
all slots seem to work fine, and all memory sticks seem to be OK too, me and my "in house" IT guru are at a loss
Specs on the motherboard say it will work with up to 2GB RAM...
Give us some ideas to try.
