RAM problems

[gaminlegend38]

Okay, after playing a game for about an hour, the game always slows down to a hault it seems. Well after the game did that this time, I went out and did some benchmark tests in Everest Home Edition. It showed my RAM as PC2600 DDR SDRAM though I have PC3200 SDRAM.

Here's my specs:
MSI K8N Neo4-F Socket 939 NVIDIA nForce4 Mobo
AMD Athlon 64 3000+ Venice 1GHz FSB Socket 939 Processor Model ADA3000BPBOX
CORSAIR ValueSelect 1GB (2 x 512MB) 184-Pin DDR SDRAM DDR 400 (PC 3200) Unbuffered
Windows XP w/ SP2

Anyone have any ideas what the problem may be?

Also, when I run the program CPUZ, it always shows my HTT as 201 MHz even though when I go into the BIOS it comes up as 200 MHz. Could this be apart of the problem, or is the program just messing up?

Thanks.

If you have done Bios Mods.... reset the bios to default and see if that helps.

Most Ram has a Lifetime warranty I would check on that if i were you
