I'm putting together a system (my first one with ddr ram) and was wondering what effect the pc rating on the ram will have. The store sold me a stick of 256mb of pc 3200 at 400 mhz ram. My motherboard manual says it supports pc 1600 and pc 2100 ddr ram at 400 mhz. I bought the ram, processor and motherboard at the same store at the same time. Is the ram the store sold me compatible or am I likely to encounter problems.

Thanks in advance for any help you can provide.

Like ALL RAM, the density of the memory chips is more critical than the speed.

So long as the RAM meets or exceeds the minimum required speed, and the full capacity is recognized by your BIOS, you should not have any problems.

If your dealer is reputable, I would not expect them to sell you RAM that is not compatible with the motherboard that you purchased along with it.

My local dealer asks questions when I buy slow RAM, as they are confident that their faster RAM is compatible with all systems.

Bottom line, I think the faster RAM will work just fine.
As a bonus, you should be able to set all BIOS RAM settings to the highest performance option.
