RAM question


Recommended Posts

OK, this is kind of a last minute question but here goes.


I'm buying some additional RAM tommorow. Money isn't really an object just suggest what kind of RAM I should choose so that it would be compactible with mine PC. BTW I copied yhis right out of EVEREST.

I know it's sh*tty but try to give me guidlines on what RAMs should I concider and which simply won't work.

The answer is right in the mobo manual and on their web site



Memory DDR200/266/333/400 DDR SDRAM (1 DIMM to DDR400),

3 x 184 pin DIMM, Up to 3GB

My suggestion; buy a twin pack of 2x512MB DDR400. You'll get 2 matched sticks of RAM and if the mobo supports you can then run dual-channel, plus you'll be at 1GB of RAM.

Then take that 256MB stick out and put in a safe place, use it in an extreme case back up or to build a small box to do whatever or give/sell it someone that can use it.
