Transcend Announces 32GB DDR3 Load-Reduced DIMMs to Boost Server Memory Density and Performance

Transcend today announced the arrival of its 32GB DDR3 Load-Reduced DIMM (LRDIMM) memory module. An important component of today’s powerful servers, LRDIMMs use a specially designed buffer to minimize the load on the server memory bus, allowing administrators to maximize memory capacity, increase performance, and reduce the power consumption of their systems.

In standard RDIMM technology, the data bus connects directly to the multiple ranks of DRAM chips on the module, which increases electrical load and limits system speed as more modules are added. In contrast, Transcend’s DDR3 Low Voltage LRDIMMs feature a full memory buffer chip on the module, which acts as a go-between for all signals sent from the host to the DRAM chips, reducing the electrical load on all interfaces. Compared to standard RDIMMs or UDIMMs, a system using Transcend LRDIMMs can support more modules per channel and higher maximum memory capacity without sacrificing speed.

Thanks to their support for higher memory densities, Transcend’s LRDIMM modules are ideal for use in robust infrastructures that run memory-intensive applications, such as virtualization and cloud computing. In servers based on Intel’s Romley platform, Transcend's DDR3-1333 LRDIMMs provide system administrators with the opportunity to maximize capacity and achieve optimal performance. For example, a system configured with two Intel Xeon E5 2600 processors on Intel’s S2600CO family of motherboards can populate all 24 memory slots with a 32GB LRDIMM, allowing a maximum capacity of 768GB. This represents a 50 percent increase in installed memory capacity over using RDIMMs (maximum 512GB) and a 500 percent increase over UDIMMs (maximum 128GB).

Backed by a limited lifetime warranty, Transcend memory modules are recognized worldwide for their reliable high quality, outstanding performance, excellent compatibility and stable operation.
