BF2S Forums Ram help

first off, a set up like that isnt dual channel.  You need 2 X512 or 2 X 1g to make dual channel.  Also i believe dual channel is better then the 1.5 gig setup, not sure though.

Well, for the part about dual channel being better:

Yes, 1.5GB single channel is better than 512 MB dual channel FOR PLAYING BF2. Because BF2 requires LOADS of memory. In applications that can make due with only 512MB of memory, you'd be better off with the dual channel.

As for the part about Why you cant run dual channel:

You need TWO (identical) memory sticks to run dual. I think you noticed that when you pulled out the 1GB stick.

As for the part about the speed:

This depends largely on your Mobo. a LOT of cheap mobos tend to run 333 Mhz IF YOU HAVE ONE stick only ! Then they slow down for each additional stick. That's because this way they save cash on memory controllers. If your board is a cheap one like this, then you're screwed. You COULD just put in your 1GB stick, and run it at 333Mhz, for the best results. But getting a new board would be infinately better. If your board is NOT a cheap one, then you SHOULD be able to run the two 256MB sticks in dual channel without problems. Consult your manual to find out how to set this up.

As for how to improove your setup:

If you can get dual channel to work... Get a SECOND 1GB stick, and put the two 1GB sticks in dual channel. This should solve your immediate problems, and give you extra speed for playing BF2. HOWEVER: Be aware that usually, a cheap 1GB stick is running at a HIGHER (slower) CAS than a cheap 512MB stick. So you may get better speeds with smaller memory sticks (ie: 4x512 costs LESS than 2x1GB at the same speed/CAS), if you're too cheap to buy the good stuff.
So either get good 1GB sticks, or be prepared to chuck your memory when you upgrade next time.
