DDR2 8500 showing as DDR2 6400?

Hello,

Just got a new PC with the following core parts:

http://www.overclockers.co.uk/showp... Dragon DDR2 Dual Channel Kit (GB24GB8500C5DC)
(GeIL 4GB (2x2GB) PC2-8500C5 )

http://www.overclockers.co.uk/showproduct.php?prodid=CP-203-IN
(Intel Core 2 Quad Q9550 LGA775 'Yorkfield')

http://www.overclockers.co.uk/showp...X38 (Socket 775) PCI-Express DDR2 Motherboard
(Asus P5E Intel X38)

I've not overclocked it yet but am going to soon (want to see how stock is first), first problem i've spotted is that the ram is showing as 'PC2-6400 (400MHz)' according to CPU-z?

I've changed the BIOS memory to 1066, but it's made no difference?

Any advice?

My Corsair dominators show up as 6400, I beleive the ram is overclocked 6400!

Sure thats not just the current speed?

Read the Memory tab, not the SPD tab.

Memory tab Shows:

DRAM=M Freq. as '400.7' MHz
FSM

RAM 5:6

5:5:5:15

2T

I assume thats still PC6400 setting?

Cheers

Go into the BIOS and adjust the memory speed, most motherboards will default to 800mhz if the RAM is 1066 or higher.

Hopefully it should read 533mhz~ in the memory tab.

I've sorted it now thanks! I had to not only set the memory to '1066' (which i had done) but the Command Rate to 'T2' not auto.

overclocking questions to follow!

Cheers

Cheers I'll give it a read.

For the record the memory still shows as PC-6400, but is running at PC-8500 speed (533mhz~) in the memory tab
