EGVA 8800GT Memory Clock... is this normal?

[colt45joe]

i have this video card:
http://www.newegg.com/Product/Product.aspx?Item=N82E16814130318

the memory clock for it is 1800MHz.

in RivaTuner, it says the memory clock is 900MHz.

is it normal to be reported as half?

[clocker]

Yes.
Core clock is 600, shader clock is 1500 and memory clock is 900.

[pifpaf]

yep, its normal.

DDR Memory:
real clock: 900mhz
efective clock: 1800mhz (900x2)

it's normal, clock effective is 2x clock frequency
