DDR. RDRAM was pimped by Intel back in the day. This was because RDRAM required a stronger, more complex link between the RAM controller and teh CPU. But intel fuxed their relationship with Rambus and RDRAM died. AMD were more successful in pimping DDR, which is now the standard.
DDR is fundamentally better because it uses a full CPU cycle, ie the rising and falling.
Technically RDRAM is/was faster as it started at 800mhz, whereas DDR's higest JEDEC certified speed is 400mhz.
actually Rambus killed themselves with their outrageous prices, the stuff literally cost 2x what regular DDR did.

i have rd ram in my pc on a intel 850 motherboard. I want to have ddr ram as rd is way too expensive. Will i have to change the motherboard? Will it be less costly than adding new rd ram? please help.

Rambus is better for pure performance, but the cost is still prohibitive. It reminds me a bit of Betamax in that it's a superior technology, but the cost and poor marketing strategies killed it.
/me agrees with AverageJoe about the price thing. However I have noted that RD-RAM in my UNIx workstation and on my other desktop have extremely good performance vs. the DDR in my 3rd comp. Not only that rambus runs cooler than DDR.
thats not being disputed. RDRAM was and is a superior product, it was just the vicitm of bad marketing and a reliance on another company's products (intels mobo chipsets)
The thing about RDRAM is that you have to buy it in pairs. If you buy one stick, you have to buy "filler" or a blank cartridge (like 40 bucks for a blank) to place inside the empty slot.
RDRAM was mostly propriatary technology in which Intel was the only one who manufactured it (seeing how they developed it) and the licensing was expensive. It was also too expensive and you only saw a slight difference to DDR.
So, DDR stayed in business and RDRAM made just by Intel died off.
