No.
As always it will revert back to the slowest memory module installed...
All your RAM will be running @800.

Patio is correct.
It will operate at the slowest ram installed. If you have 2 sticks @ 800MHz and 2 @1066Mhz
Why not just install (2) 2GB sticks @ 1066?

because i was hoping it would read as 1066, ive already got 2 sticks that ive only just got and i was just looking around and saw i could get 2 more at a higher speed for a pretty good price. ah o well i guess ile just buy 2*2gb sticks at 800mhz.
Thanks.

I would install matching sticks for best performance and less problems. Can you get 4 of the 1066 sticks?
