Speed issue

[fastwunz]

Guys ive got 3Gigs of Corsair XMS2 DDR2 6400C5 ram which i have been using for about two years.

However, im totally unsure as to what speed it should be running at.
CPU-z posts this:

Type: DDR2
Channels: Dual
Size: 3072
DC Mode: Symetric

DRAM Frequency: 400.8Mhz
FSBRAM: 5:6
CAS# Latency (CL): 5.0 Clocks
RAS Precharge: 5 Clocks
Cycle Time: 18 clocks
Row Refresh time: 54 Clocks
Command Rate: 2T

See anything wrong with that little lot? Anyone know what this ram should be running at?

corsair say this:

CM2X2048-6400C5
Speed Rating PC2-6400
Tested Speed 800Mhz - does this mean that my DRAM frequency of 400mhz is wrong? should it be 800mhz or am i reading into this wrong. Does it mean 2X400mhz = 800mhz?
Size 2GB
Tested Latency 5-5-5-18
Tested Voltage 1.8
Performance Profile
SPD Speed 800Mhz
SPD Latency 5-5-5-18
Package 240pin DIMM
Fan Included No

Does it mean 2X400mhz = 800mhz?

Yes, DDR = Double Date Rate. Multiplying your RAM frequency (400MHz) by 2 = 800MHz. So your RAM is running to spec (speed and timings wise).

thankyou thats great

That all looks in top shape to me. It's running at both the correct speed and timings.
