Ron or Rick, or anyone else i guess…
I havn’t had the luxury of using any DDR2 ram, espessialy for laptops. I was wondering, if either of you know wheather a ddr2 chip (PC2 4200) will work/fit into a machine that runs PC3200? Like will it fit and only run at the 3200 speed? or would it not work at all?
I’m wondering because i have a laptop that can run pc 3200, and on newegg.com i can get a 1GB stick of ddr2 4200 ram for apox 72$, which is almost 40$ cheaper than a 3200 stick…
eh, i just found my answer, hehe

DDR SDRAM – Double Data Rate [View Webopedia Definition]
Short for Double Data Rate-Synchronous DRAM, a type of SDRAM that supports data transfers on both edges of each clock cycle (the rising and falling edges), effectively doubling the memory chip’s data throughput. DDR-SDRAM also consumes less power, which makes it well-suited to notebook computers. DDR-SDRAM is also called SDRAM II. and DDRAM. DDR-SDRAM and RDRAM are the two technologies expected to replace SDRAM.NOTE: When looking at DDR memory, the number following “PC” indicates the module’s total bandwidth. (example: PC1600 DDR memory is designed for systems equipped with a 100 MHz frontside bus. The number 1600′ refers to the module’s bandwidth; the quantity of data that it transfers in one second, of 1.6 GB per second.
DDR2 SDRAM
DDR2 SDRAM is the next step up from DDR SDRAM. DDR2 SDRAM offers new features and functions that enable higher clock and data rate operations. DDR2 transfers 64 bits of data twice every clock cycle. DDR2 SDRAM memory is not compatible with current DDR SDRAM memory slots.bummer.
