I need to buy more memory for a clients Dimension 4550.
However Crucial.com shows two 4550's available. One at 533 and one at 400mhz.
How can I know which is right for the client?
Note I cannot run the crucial tool but I did run CPUz (see attached screen shot)
Also I have the service tag so can look up the original order, but even from that I can see no easy way of knowing.
One of the systems can take 1GB per slot and the other only 512K so it is important I know which.
Any advice apprceiated.
