Crucial on Thursday announced the 64GB LRDIMM (load-reduced dual-inline memory module) for new-generation servers. Load-reduced DIMMs enable users to populate more DIMMs per channel for up to twice the installed memory capacity of a server, which is crucial for new-generation servers that can feature twelve or more microprocessor cores per socket.
The 64GB Crucial DDR3L LRDIMMs operates using 1.35V, unlike the 1.5V common in DDR3 RDIMMs, making the new module more energy-efficient and cost-effective, especially in large deployments. The modules work at 1333MHz clock-rate with CAS latency 9. These modules offer up to a 35% increase in memory bandwidth per server compared to standard DIMMs (which operate at 1066MHz), and eliminate the channel ranking limitation of standard DDR3 registered DIMMs.
Since Crucial LRDIMMs transmit power in a more efficient manner to the CPU (via the data path buffer), they use less voltage, which allows for additional power savings. These new memory modules are also compatible with OEM servers and warranties, allowing users to upgrade their existing server infrastructures without having to purchase an entirely new system. Crucial LRDIMMs fully support the latest Intel Xeon processor E5 2600v2 “Ivy Bridge-EP” family.
“For memory-intensive server applications such as cloud computing, virtualization, and in-memory databases, optimizing the capabilities of new or existing hardware is by far a more cost-effective solution than purchasing additional servers. The new 64GB Crucial LRDIMMs allow servers to reach the maximum amount of installed memory possible, which can enable dramatic performance gains in memory bandwidth and overall server productivity, all while reducing power costs relative to adding additional servers,” said Michael Moreland, worldwide DRAM product marketing manager at Crucial.
Crucial DDR3L LRDIMMs server memory is halogen-free and RoHS compliant. Available in densities up to 64GB and kits up to 192GB, the 64GB LRDIMM will be available to purchase in early calendar Q4 2013. Crucial LRDIMMs are backed by a limited lifetime warranty and are rigorously tested to meet or exceed the high-quality performance specifications customers have come to expect from Crucial.
