Can someone explain the differance to me about DIMM or SDRAM?
Compusa has a sale on some 512 DDR DIMM ram, I've only ever used SDRAM..Is there going to be much of a performance differance? (is tired of laggin down in town)

Most likely [since im not exactly sure what type of ram youhave in your system] the DDR ram will not even fit in your SDRAM slot in your computer. They have a different number of connections and are not physically compatable. DDR is significantly faster than SDRAM but is alot cheaper because it is what is currently used in new computers, and as such alot more of it is produced. Hope that helped some.

DIMM stands for Dual Inline Memory Module. DDR stands for Double Data Rate. SDRAM stands for Synchronous Dynamic Randomn Access Memory. None of these Acronyms helps you... before buying new RAM you need to consult your motherboard users manual, to find out what types of RAM your board supports. If you no longer have it, you can find the info on the manufacturers webpage. If you don't know what motherboard you have... then you don't know what you are doing and you shouldn't even open the case, take it to a mom and pop shop and ask them to upgrade it for you.

DIMM is Dual Inline Memmory Moduel.... of which all DDR is [I am 90% sure on that] DDR is DDR, just make sure its not DDR2 [which is really new so its probably not]. So the stuff on sale should physically fit into your machine. The only thing you have to watch out for is the speed. If the speed of the memory on sale is equal too or higher than your current RAM you will be fine. [examp: DDR 266 DDR 333; DDR 400; if you have DDR 333 in your computer, either DDR 333 or DDR400 will work fine, but DDR 266 will not]

Does that help?

EDIT: if you know the make and model number of your computer you should be able to go to www.crucial.com and look up the make and model and get the specific types of ram that go in your machine.
