OWC 16GB DDR4 2933MHz ECC Registered RDIMM 2Rx8 for Lenovo ThinkAgile VX3320 VX3520-G VX5520 VX7320-N VX7520

OWC 16GB DDR4 ECC RDIMM for ThinkAgile

This 16GB DDR4 2933MHz ECC Registered RDIMM is built for Lenovo ThinkAgile VX3320, VX3520-G, VX5520, VX7320-N and VX7520 servers. It runs at PC4-23400 with CL21 latency and 1.2V power. The module uses a 2Rx8 organisation and a standard 288-pin form factor. It replaces Lenovo part numbers 01AG631, 4ZC7A08708 and 4ZC7A08741.

Installation notes for registered ECC memory

Installation follows the normal DIMM procedure for the listed ThinkAgile chassis. The module is keyed for 288-pin DDR4 slots and seats with standard pressure. A common error is mixing this registered ECC RDIMM with unbuffered UDIMM modules; the system will not boot if both types are present. Another issue is populating slots in the wrong order for the specific Xeon SP Gen 2 memory controller; consult the server service guide for the correct population sequence.

Suited for ThinkAgile VX capacity upgrades

This module suits administrators expanding memory in the five listed ThinkAgile VX nodes or replacing failed sticks with a validated OWC part. It is not for builders who need unbuffered memory for standard desktop motherboards or consumer workstations. It also does not fit systems that require load-reduced LRDIMM modules or a different rank configuration such as 1Rx4 or 4Rx4. Buyers with those requirements should look at a different specification.
