Infineon Technologies, one of the world’s largest makers of memory, said it had initiated sampling DDR2 SDRAM rated to run at 800MHz. Surprisingly, but the company’s test modules were not equipped with heat-spreaders, in contrast to common high-speed memory sticks.

Infineon offers DDR2 800MHz unbuffered modules with densities of 256MB and 512MB. The 256MB and 512MB modules are based on Infineon’s 256Mb DDR2 components. Precise specifications of Infineon’s 800MHz memory devices were not disclosed, but the company’s 667MHz DRAMs featured 1.8V voltage and CL5 5-5 latency settings.

“Due to the industry leading low power features of its DDR2 memory products, Infineon is the only DRAM supplier who abandons the usage of an extra heatspreader which is standard for high speed modules with data rates of 800Mbit/s,” the company said in a statement.

800MHz DDR2 memory is not a product for general public, as even the latest chipsets from Intel and NVIDIA only formally support 667MHz DDR2 memory speed-bin. Therefore, only overclockers, who operate computer components at speeds beyond officially set levels, may enjoy increased performance of Infineon’s new memory.

Earlier the only maker who unveiled 800MHz DDR2 memory chips was Elpida.

Samples of Infineon’s 256MB and 512MB 800MHz memory modules are available for customers now. Volume production is planned to start in June 2005.
