I bought this RAM from OC http://www.overclockers.co.uk/showproduct.php?prodid=MY-114-OC

but when i use CPUZ it says the RAM is 6400 not 8500.

Why is this?

What happens when you try it with just 2 sticks?
Some motherboards run the memory at a slower speed when you have more than 2 sticks in it.

System Specs - (from the manual)

System Memory
-Dual-channel DDR2 800/667/533
-SLI-Ready Memory up to 1200 MHz
-Supports up to 8 GB DDR2 memory

So it might not recognise it.

no it shouldnt matter how many sticks are in for speed, this is a bit of confusion itself, if you have all 4 dimms in it stresses your computer slightly more so you cant get quite as high an overclock, there shouldnt be a problem running at their rated speed though, dbl check that they did send you the correct DIMMS, have a look at them physically, should say on side what speed theyre rated at. Have you set the voltage manually? If not try this (2.1V), a lot of mobo's tend to undervolt the RAM. Have you checked you have latest BIOS yet? Also you can ignore the SPD tab in CPU-z as its horribly inaccurate anyway, just look on the memory tab to see what speed they're actually running at
Edit: in fact I just checked my CPU-z and its SPD tab is showing mine as 6400, as I say this is just an inaccurate reading off of CPU-z though, my memory tab is still showing me as 533 (which doubled up is 1066), yours may already be running at 1066, its just this tab thats ******

I remember looking into this myself when i first moved to 1066 ram. Seems it's just a problem with cpu-z and not the ram/motherboard.

Its normally due to the amount of power that can get to the dimms.

I am not talking about overclocking here, some motherboards will run at a lower speed, i.e run where they should run at 400, they run at 333. But the specs of this motherboard say that it will only recognise ddr2 800 (at the fastest end), which your faster memory has been recognised as.
 
GibGib - Its got nothing to do with how many DIMMs are in use as to what speed they run at, and as stated earlier it prob says this (only running at 800) as when the board was first released 1066 didnt exist, BIOS updates will more than likely now support 1066.
Its an error in the SPD tab, thats all, dont go confusing the matter with gibberish like no of DIMMs effects speed they run at, it doesnt, at all
 
It's nothing to do with the motherboard or its BIOS.

The SPD tab only reports what the memory manufacturer programmes into the memorys SPD. It's very common for PC2-8500 to be labeled as PC2-6400. After all, PC2-8500 is just high-binned PC2-6400 anyway.
 
I woundn't worry about what cpu-z is telling you
i have two sets of muskin redline xp4000 ddr1 dimms in my pc and cpu-z reports them as being 3200 ddr dimms but when i look at the memory tab it reports their spd correctly as running at 250Mhz ie 500Mhz as muskin have rated them.
