DRAM DDR3 / DDR4 LRDIMM
LRDIMM modules (Load Reduced DIMM) is a new type of memory, that is an extension of FBDIMM modules. Moreover, LRDIMM/RDIMM memory can be used on the same platforms, but the server can use more LRDIMM memory than RDIMM.
Key features
- Available capacities:
DDR3: 32 GB DDR4: 32, 64 GB
- DIMM form factor
- Major-grade memory chips
- supply voltage
DDR3: 1.5 V and 1.35 V
DDR4: 1.2 V - frequency:
DDR3: 1066, 1333, 1600, 1866 MHz
DDR4: 2133, 2400, 2666 MHz - lifetime warranty + technical support
Increased reliability and stability of operation even in a 24/7 mode
Financial savings on server and data center maintenance and equipment
Reduction of energy consumption by up to 20%
Increased efficiency of workstations
Works with higher frequency
Currently LRDIMM memory is available in higher capacities (up to 64 GB) than RDIMM (up to 32 GB), and at full device load, LRDIMM memory can operate at higher frequency than RDIMM. For example, with a dual-processor motherboard, it is possible to use as much as up to 384GB of LRDIMM memory and only 192GB of DIMM memory.
