RAM speeds vs amount

Hewlett-packard / A1709N

Specs: Vista Home Premium 32 bit, Athlon 64 3800+/ 3GB
My pc came with 1gb of ddr2 533 and I bought 2 more gb of ddr2 667 (highest mobo will support). I was wondering if it'd be more beneficial to run 2gb of the higher speed, or 3gb of the lower speed?

I tend to play a lot of games and I do occasional video editing.

For best performance, an A64 should be run with DDR2-800. DDR2-533 or DDR2-667 will bottleneck the system. But according to HP, the max RAM speed your system supports is DDR2-667.

Considering the memory controller is built into the CPU, I don't see how it can't support DDR2-800?

To answer your question, I suspect 2GB DDR2-667 would be better. Try it both ways & run some benchmarks for comparison. And just out of curiousity, which video card do you have? The onboard GeForce 6150 isn't very good for gaming so I'm guessing you installed a PCI-e video card?

Adding more memory does not automatically mean a faster machine. More RAM only helps if you don't have enough for your normal workload. If you don't have enough, the system has to resort to using the pagefile, and that slows the system down.
