DDR2 RAM - How Fast is it Going?
Hi,
I've built my first PC. I am wondering if my RAM is operating at its optimum speed.
Mo/bo Asus M2N-SLI Deluxe with BIOS ver. 1604
AMD Athlon 64 X2 3800+
WD SATA II 200 GB & 500 GB drives
EVGA nVidia GeForce 7600 GS with 256 MB
Windows XPP SP3
Wintec AMPO 1GB (2 x 512MB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory Model 3AMD2800-1G1K-R
How do I see what the RAM is rated? Should I expect to see it rated at 800 MHz?

Great - I thought that might be the case - but guessing is a good way to screw things up!
Thank you much. : )

The RAM shows up correctly as 1024 MB, and shows the two as 512 MB [Type] DDR2-800 PC2-6400 (399 MHz).
More detail from PC Wizard -
Supported Frequencies : 399 MHz, 400 MHz
CAS Latency (tCL) : 4 clocks @399 MHz, 5 clocks @400 MHz
RAS to CAS (tRCD) : 5 clocks @399 MHz, 5 clocks @400 MHz
RAS Precharge (tRP) : 5 clocks @399 MHz, 5 clocks @400 MHz
Cycle Time (tRAS) : 18 clocks @399 MHz, 18 clocks @400 MHz
Min TRC : 23 clocks @399 MHz, 23 clocks @400 MHz
So it seems like it's running at 400 MHz, not 800 MHz.
