Can you have a stick of pc2700 and a stick of pc3200 in a pc at the same time. I need to upgrade my ram, and Crucial and best buy say pc2700, while th emachines site says i can use pc3200..
 
well if your machine supports 2700 it will take 3200 but, it will run at 2700
 
sweet...i just got like a gig and a half of free ram!! Thanks!
 
now if you already have ram its not reccomended to mix and match different speeds or brands
 
Since when have you abided by a 'recommendation' ? ;)

If it doesn't catch fire, it's all good :)

i stll have the 512 that came with the system in...
 
Unless you are running dual channel DDR you can stuff anything you want into any machine. It will just run at the speed of the slowest stick. (Exception, some machines require you to use buffered RAM if all 4 slots are populated.)

Some stupider bioses may lock up if you put a fast stick in the first slot becasue they don't look at the speed ratings for all the sticks. Just put the slowest stick in the first slot if this happens.
 
If you really want to keep the older RAM in there (I didn't, though my old was XMS 2400), just pair the DIMMs appropriately. AKA, don't put a DDR 2700 and a DDR 3200 DIMM in the same bank, keep both of the same type/speed in their own respective banks, and then it should go OK, albeit slower.

Also Hi EP and people. I found this place again while looking through a oooollllllldddd backup. I have filled over 10TB and was looking at my collection of antiques. Any bids on the 500Mhz Win 95 fix?
Any of the SP crew still out there?

Impressed you have kept this alive this long EP! So many sites have come and gone. :(

Just did some crude math and I apparently joined almost 18yrs ago, how is that possible???
