can 533Mhz CPU work with pc800 RDRAM?

I'm getting the Gigabyte 8ihxp tomorrow, currently i have two 256 pc800 RDRAM's and a 1.8ghz northwood. I'm getting the 2.4B northwood soon, my question is - will this CPU work at 533Mhz if my memory is only running at PC800 speed or will i have to put the speed of the CPU to 400Mhz if the memory is only at PC800? This is without overclocking (not planning to overclock).

thanks for your help

I'm using PC800 Samsung in my 2.66 rig. Of course, I have the memory multiplier set at 3X, but even at my "normal everyday" 3 gig overclock, the memory bus is running at 150 FSBX3=450X2=900 MHz, which is still overclocked. When I'm at default speed of 2.66 and running 4X, I'm perfectly stable even though my PC800 is running at PC1066 (133X4=533X2=1066).
