I have an old Asus P2B-S motherboard and went to the Crucial systemscanner to find the right memory for it, then bought it on a cheaper site.
Now my BIOS only recognizes half the RAM. If I put one 256MB chip in, it shows 128MB.
The max for this motherboard is 1GB, and that's how much I bought, but I can't use it...
The old RAM I have in there is less than 512MB altogether and works normally.
The memory I bought (4 sticks) was:
256MB PC133 DIMM CL3
The motherboard specs say PC100, but that seems to be downward compatible.
Any idea why it doesn't work?
