upgrading ram!

[GGUUSS]

i have 2 sticks of 512 corsair 240pin pc4300 533mhz ram and im thinking of buying a 1 stick of corsair xms 1gb 240pin pc5400 675mhz ram. can i mix match ram like that?? or do all the ram chips have to the the exact same?

you can do that but both of the sticks will run at the lowest one's speed.

you gotta have 2 or 4 sticks in same size in order to utilize dual channel , if youll have 3 it will downgrade performance as it wont run in dual channel , you can *mix* but better get a stick with same timings as your current to avoid stability issues , its a better idea to get 2x 512mb or 2x 1gb so it will run in dual channel

I have a similar question. My MOBO has 4 slots for ram. It is an MSI K8n Neo4 Plat. FSB is 1000. I have 4 512 PC 3200 in there now and just got 4 PC 4200 to replace them. is this worth it? It was $140 for the 4 sticks of kingston value ram.

Aslo the voltae ojn the ram says 1.8v all othere are n the 2.5-8 or so..

I was told using the 4 banks slows the computer down. how is this, I thought it would run faster... more channels.?.
