Japanese memory maker Number One – Elpida Memory – today unveiled samples of its 2GB DDR-II memory modules for server applications. The modules make use of Elpida’s recently unveiled 512Mb DRAMs rated to function at 400MHz and 533MHz.

Elpida’s 2GB PC2-4300 memory modules with ECC support for servers and probably powerful workstations are the world’s fastest high-density DRAM systems that are scheduled for mass production in the Q2 2004. Elpida produces its 512Mb DDR-II chips using 0.11 micron process technology on 300mm wafers in its Japanese fab.

Earlier this year Kingston announced successful verification of memory modules based on Elpida chips. The 256Mb and 512Mb DRAMs clocked at 400 and 533MHz with 3-3-3 and 4-4-4 latency settings, according to PC2-3200 and PC2-4200 standards, have been available for memory module makers for some time now. The products are packaged using 64- or 84-ball FBGA packages and are rated at 1.8V.

It is fairly interesting to note Elpida’s positioning of its newly unveiled 2GB DDR-II modules. Intel’s server chipset code-named Lindenhurst was not meant to support PC2-4300 memory, according to information from a source close to Intel. Therefore, it is not quite clear why Elpida clocks its new products at 533MHz: either the company targets its 2GB modules for a different previously unannounced product, or Intel has changed the specs of its core-logic.

Code-named Lindenhurst chipset is planned to be announced in the first quarter of 2004. As we revealed months ago, this chipset will support 800MHz Quad Pumped Bus, dual-channel PC2700 and PC2-3200 memory, PCI Express x8, PCI Express x4, direct connect LAN and storage components. For Xeon-based workstations Intel will also introduce another new chipset currently code-named as Tumwater with nearly similar feature-set, but adding PCI Express x16 for graphics. Both Lindenhurst and Tumwater are expected to support code-named Nocona processors made using 90nm Strained Silicon technology process.
