is my memory underclocked? geil 6400 - help!

Bought 2 gig of geil (2x1gig) a while back but never really thought nothing of it, just chucked it in and away i went.

Its...

PC6400 800MHz CAS 4-4-4-12
- 64x8 DDR2 BGA Chips
- 240pin, Non-ECC, Un-buffered DDR2 SDRAM DIMM
- Aluminum Heat-spreader

Now..when i load up CPU-Z it says:

Channels Single
Frequency 400mhz
CAS latency 5 clocks
RAS TO CAS delay 5 clocks
CYCLE time(Tras) 18 clocks
Bank Cycle time (trc) 23 clocks
Command rate 2T

Is this all correct? or is there a problem with it not running in sync and as a result not giving me the expected performance? If it is wrong how do i sort it?

I've looked in bios and it says next to mem(ddr2) 800mhz.

just been looking into it..read the ram has to be in sockets 1 + 3 and its now reading as 'dual' instead of single but still has 400mhz instead of 800mhz.

You have to double the CPU-Z speed to get the real speed.

So your memory is currently running at 800mhz.

DDR = Double data rate

400 X 2 = 800

silly me

all sorted now

Is it possible that this is why i've been getting such poor overclocks on an E6600 ? 2.4ghz @ 3ghz when most people can get 3.4/3.6ghz no probs ?

Yeah it helps to run the RAM on a divider so you don't start overclocking the RAM immediately. On Gigabyte boards you set the RAM multiplier to 2.0 to do this.
