Memory modules can run at clock speeds of up to 1,066MHz Corsair Memory this week unveiled new DDR (double data rate) and DDR2 memory modules, which the company said are faster than previously available products.Corsair’s dual-channel TWIN2X1024-8500 is a pair of 512MB DDR2 modules designed for PCs based on Intel microprocessors. The modules are able to run at clock speeds up to 1,066MHz, the company said.The dual-channel TWINX2048-4400PRO is a pair of 1GB DDR modules and is designed for PCs running Advanced Micro Devices (AMD) chips. The modules offer speeds up to 550MHz, it said. The new memory modules are on display at the Cebit exhibition in Hanover, Germany, Corsair said. Pricing and availability was not immediately available.DDR2 is expected to become the mainstream memory used in PCs during the coming quarter, according to DRAMexchange Technology, which runs an online clearinghouse for memory chips.The clock speed of the TWIN2X1024-8500 matches the fastest front-side bus speed available with chips from Intel. In computers that use Intel chips, the front-side bus is used to shuttle data back and forth between a PC’s processor and main memory. Matching the clock speed of a computer’s memory with the top speed of the front-side bus helps the system run as fast as possible. The latest AMD chips do not use a front-side bus, instead employing an on-chip memory controller that is connected to a HyperTransport links. AMD’s chips do not yet offer DDR2 support. The company is expected to extend support to the faster memory type this year.Cebit runs from March 9 to 15. Technology Industry
