EDIT To the Original Question:
I did some research and the old computer I discovered is a Dell Dimension 2400. According to the SPEC Sheet the RAM is PC2100 (266-MHz) or PC2700 (333-MHz) DDR SDRAM (non-ECC), will that work in my system which is running 2GB of PC3200 DDR 400MHZ RAM (In a configuration of 2 512mb sticks and 1GB stick) I have an open slot which can hold this 1 stick of 1GB. First - Will it even work? Second - If it will work will it help increase speed?
I have an old computer lying around and it struck me that I should take the RAM from it and see if it works in another computer I am using. The old computer does not work anymore so I cannot go to a site like crucial and run a simple test.
I pulled the stick out of the computer and it says it is a Samsung 1GB DDR DIMM, Q.
Here is a link to the current stick I have in the computer that I am attempting to put the SAMSUNG stick into.
Here are the full numbers on the label of the stick of RAM from the old computer:
1GB, DDR DIMM, Q AOTQD PO 129009.2
Then on the actual chips themselves it has these numbers:
SAMSUNG 646 K4H510838C-UCCC H51 8 CMJ05816
If I was to put this stick into the computer and it is not compatable what would happen? I do not want to damage anything on my computer. Advice?
A FINAL NOTE: After this question was answered and I installed RAM, it turns out that the RAM was DDR 3200 according to a crucial test despite the specs saying the computer did not support that type of RAM. Guess when I upgraded RAM in the old computer I purchased 3200. =>
