Have you tried running the RAM at 333MHz. A machine tends to run smother/quicker/more stable if the RAM runs at the same speed as the FSB.
My setup
--------------------------
MSI K7N2-Delta ILSR
AMD Barton 2500+
Thermaltake Volcano 11+ Xaser heatsink/fan (Houston, you're clear for liftoff)
Kingston HyperX PC3200 DDR (2x512MB)
MSI GeForce3 Ti200 128MB (needs updating but 2 car payments + insurance hinder that)
FSB - 400MHz
Memory - 400MHz
CPU Speed - 2206MHz
CPU Temp - 45 C Peak
Case Temp - 35 C Peak
Keep in mind that temp is with 5 hard drives generating heat as well. Overclocking the Barton 2500+ is so insanely easy it's not even funny. There's no reason to actually by a 3200+ if you don't mind overclocking.
