Will this RAM work on my IBM laptop? Compatibility issues, SODIMM, memory etc?
I have an IBM laptop (r50e model) and I am looking to upgrade the memory as I only have 256mb of RAM.
The RAM reccommended is:
SDRAM Non-ECC
512MB
333MHz
CAS Latency: CL2.5
Form Factor: 200-Pin DIMM
But will this work?
512MB
DDR2
200 Pin SODIMM
PC2-4200
533MHz
Thanks!
I tried the kingston memory search, but I could not find any re50 model on IBM.
However, I guess your question is whether or not DDR2 Ram is backwards compatible with DDR ram? And the answer to this would be no, that is most probably not possible.
However, I am not certain that DDR SDRAM is the RAM you need, since I could not find the model of computer you listed on the kingston memory search, nor could I understand it out from the information you listed.
