2GB at 800 or 4GB at 667

Many thanks!

Just make sure that your OS is 64 bit. 32 bit will only see a little over 3 gigs.

Apperantly someone forgot to mention that DDR2 667 IS DDR2 @ 800mhz.That is the max DDR2 memory speed currently supported by AMD.As new CPU's and chipsets are brought to bear,we'll see DDR2 memory speeds increase for AMD as it makes the necessary changes to its on-die memory controller.Hope this has helped some.Goodluck.

DDR2-800

Pros:

1. AMD love memory bandwith (far better performance gains than with intel cpus)
2. 2GB should be sufficient for most games, unless you like to leave Photoshop open in the background.
3. 2GB leaves you the option to upgrade to 4GB in the future. (generally cheaper than when you first purchased)
4. If you overclock your CPU having the higher clocked memory will allow you to be more flexible with CPU/RAM ratios.
5. If using 32-bit OS you will only get to see 3.5 of the 4 gigs you install ; ;
6. Its cheap... I got 4 (1x4) gigs of DDR2-800 "dual channel" for 50 bucks after rebates. cant beat that. Neweggs got nice deals.

DDR2-667

Pros:

1. You can keep photoshop open while you play games.
2. There are no others pros IMO
