1066 MHz DDR2 RAM will downclock in an 800 MHz motherboard, right?

Or will it not work at all? I bought 2 GB of Crucial Ballistix Tracers 1066 because I got a very good deal on them, but at the time, I didn't realize that not all motherboards support 1066 MHz RAM. If I put these in an 800 MHz standard motherboard, will they just downclock that speed?

Thanks for the help.

they should, yes... and you should also be able to tighten the timings a bit considering how underclocked they will be.

Let me know if it works, it'd be good to know for future reference :)

Theoritically it will work, but however better to consult the manufacturer's website for better information .. :)  Err, since you've got it already just give it a try and let us know the result for future reference :p

>_> Oh shoot... Well, maybe I should spend a little more money on a SLI motherboard that supports DDR2 1066 by default then... Hmm.

The speed of the ram will be set by the ratio with the system bus. An Intel CPU with a 1333 FSB will run the system bus at 333. At 1:1 your ram would be running DDR2 667 specs.
