Sorry but my Q6600 systems uses 4gig of DDR2 RAM and I was able to run Cryisis on it at DX10 level (med high settings) using an ATI 3870/4850/4890 video card at a resolution of 1680x1050.
My point is the fact that he has DDR2 RAM is not the issue. Sorry.
Have a look through this to see if anything helps - Tips on Troubleshooting Game Issues
Again, the fact that you have a DDR2 system doesn't mean you get bad gaming performance. Check that something is going on with your system.
Also if your memory is 667 it's running at 1366MHz (667x2) so the diffrence between 1366 and 1600 is very small and should be that big of a deal.
My two cents.
