My old PC was a Dimension 4500 - it was capable of taking 1 GB or DDR PC2700 333mhz Ram.
I upgraded to 2 of these 512mb PC3200 DDR400 RAM ( Your MOBO will limit the speed - so it will clock down to 333 mhz ). You could probably do the same. For web browsing - upgrading to 1 GB is night and day from what you have now.
If you are really limited in funds - you could just buy one - and run it with what you have now - for 768 mb. I had mine running at that for a while before I upgraded my second SDRAM stick to get to 1GB.
According Bodaggit's Link - looks like your PC has the same RAM requirements as my old 4500. The Kingston I linked to should work fine.
DUDE, just a fair warning, best buys prices could be double what you will find off new egg, they bump that price up so far its crazy...
So unless you want to pay double for the same item i would buy off newegg, or tiger.
E.G. i went to go buy some ram, but at best buy it costs 60 bucks for2 gigs of ram, i just said screw it, im going on newegg and buying it for 35 lol and i did![]()
That is why I'm asking what is compatible. Best Buy (online) has some 512MB for $19.99 http://www.bestbuy.com/site/ValueRA...dule/9414289.p?id=1218101177240&skuId=9414289...and some for $54.99 http://www.bestbuy.com/site/PNY+-+5...mory/6578713.p?id=1077630669390&skuId=6578713.
What's the difference? Will both work with my computer?
If your Dimension 4550 is a 533MHz FSB (Front Side Bus) use at least the PC2700 memory returned by the configurator (don't use PC2100). For 400MHz FSB use PC2100 memory (faster memory should also work). (If your CPU is 2.2GHz or less you're running a 400MHz FSB, if it's higher you're running a 533MHz FSB.)
