Hello. I recently bought a stick of 256MB PC133 RAM for a friend's Dell system. The computer (a Dimension L800R) only supports PC100 SDRAM, but it was considerably more expensive than the PC133, and I was positive I'd used PC133 RAM in a motherboard that was made for PC100 before. I put the stick in with the existing 128MB chip (non-parity, unbuffered) and the computer wouldn't boot (I wasn't able to identify the beep code). I also tried just putting the 256MB chip in, and it still wouldn't boot. I took the chip back to Best Buy and asked them about it, and one of the techies said PC133 RAM just recently stopped working in motherboards that only supported PC100.
Can somebody verify this for me so I know I don't just have a bad/Dell incompatible chip? Thanks.
