No. SDRAM and DDR SDRAM are not compatible with each other.
SDRAM, DDR and Rambus DRA, are the three different types of RAM packages. When shopping for different RAM packages, the type of RAM you purchase does not really matter.
Common types of DIMM Memory Modules used in computers are a 168 pin SDRAM Module, or a 184 pin DDR SDRAM. These boards are designed to be used in personal computers.
supplied by webopedia.com Short for Synchronous DRAM, a type of DRAM that can run at much higher clock speeds than conventional memory. SDRAM actually synchronizes itself with the CPU's bus and is capable of running at 133 MHz, about three times faster than conventional FPM RAM, and about twice as fast EDO DRAM and BEDO DRAM. SDRAM is replacing EDO DRAM in many newer computers. SDRAM is a variant of DRAM in which the memory speed is synchronized with the clock pulse from the CPU. This synchronization enables the SDRAM to pipeline read and write requests. Pipelining enables the SDRAM to accept commands at the same time as it is processing other commands. There are three variants of SDRAM: Single Data Rate SDRAM - SDR SDRAM Dual Data Rate SDRAM - DDR SDRAM
