Elpida ships 32GB Load LRDIMM

Really dense memory
It claims that the beasts are the DRAM industry's highest density memory module. The LRDIMM consists of 72 advanced 40nm process 4Gb DDR3 SDRAM chips in a Double Density Package.
Elpida hopes that LRDIMM will become the new standard for server memory modules. It reduces I/O bus capacity by buffering the I/O bus line with the memory buffer to simultaneously enable higher system density and faster speed.
JEDEC, a standardization body for the semiconductor industry, is studying the adoption of LRDIMM standards. Elpida is actively engaged in promoting its own standard.
Conventional Registered DIMM in a two-way server system only allows a maximum of 16 DIMM whereas LRDIMM allows up to 24 DIMM in the same system. Elpida claims that 24 of its 32GB LRDIMM creates a next-generation 768GB capacity platform, or 1.5 times that of a system equipped with RDIMM.
It has a speed of 1600Mbps, which is 20 per cent faster than the highest RDIMM speed of 1333Mbps, the outfit said.
