A-Tech 64GB (4x16GB) DDR3/DDR3L 1333 MHz ECC RDIMM 2Rx4 1.35V 240-Pin Server RAM Kit

64GB DDR3L ECC RDIMM kit

This 64GB kit contains four 16GB DDR3L 1333 MHz registered ECC modules built for servers and workstations. The dual-rank x4 design and CL9 latency deliver reliable throughput for multi-threaded workloads. It operates at 1.35V and can also run at 1.5V where the platform requires it. The 240-pin form factor fits DDR3/DDR3L registered DIMM slots only.

Replaces lower-capacity DDR3 registered kits

Upgrading from smaller registered DDR3 sets is worthwhile when virtualisation hosts, database servers or compute nodes hit memory pressure and swap activity rises. The quad-channel population fills four slots at once, matching the channel architecture of compatible platforms. It is not suitable for desktop or laptop systems that use unbuffered non-ECC memory.

64GB capacity with quad-channel headroom

The 64GB total handles large virtual-machine fleets, in-memory databases and heavy compilation jobs without paging. Headroom remains until the platform's maximum registered DIMM limit or slot count is reached. Beyond that point, a move to a newer memory generation and CPU platform would be required.
