Can PC2100 RAM be used to replace PC2100U?
I need to upgrade RAM for one of my users computers. He has a Gateway 500S computer running Windows XP SP2. I checked the RAM that is currently in there now which is: 2 sticks of 256 MB DDR, 133 MHz, CL2 PC2100U from Infineon.
I went on newegg.com and found potential replacement RAM of:
Brand: Kingston
Model KVR266X64C2/1G
Type: 184-Pin DDR SDRAM
Capacity 1GB
Speed DDR 266 (PC 2100)
Cas Latency 2
Voltage 2.5V
Heat Spreader No

My question is, will this RAM work with my machine since the 2 differ in PC2100U and no 'U'?

It depends what you motherboard supports. What is the model number of your pc or motherboard. The u stands for unbuffered so it is different than pc2100 memory.

Most desktop memory is unbuffered, so I would say they are compatible. ECC or buffered memory is typically for servers and would be labeled as such, since it is a more stringent requirement; ie, you can use buffered memory in motherboards that specify unbuffered memory, but you can't (and shouldn't) use unbuffered memory in motherboards that specify buffered memory.
if your pc2100 you have is unbuffered then no problem... make sure you motherboard supports unbuffered ram... go to http://www.crucial.com and scan for the memory that is required by your pc and see what it tells you to upgrade with.
