OWC
A 64GB kit of four 16GB DDR3L 1600 ECC registered RDIMMs at 1.35V for Dell PowerEdge R520, R620, R715, R720 and R720xd servers
Capacity 64GB (4 x 16GB)
This OWC kit supplies 64GB of DDR3L ECC registered memory in four 16GB modules. It is built for Dell PowerEdge R520, R620, R715, R720 and R720xd servers that require registered DIMMs with error correction.
Each module uses the 240-pin DDR3L form factor and operates at 1.35V with CL11 latency at 1600MHz. The registered buffer reduces electrical load on the memory controller, a requirement for the listed PowerEdge platforms, and the modules cannot be mixed with unbuffered memory.
Confirm your system requires DDR3L registered ECC RDIMMs before ordering; standard desktop boards and unbuffered memory configurations are not compatible. Check that all four DIMM slots can accept 16GB modules and that the server BIOS supports the total 64GB capacity.
