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.

Questions sur cet article

How do I confirm the OWC 16GB DDR4 2933MHz ECC RDIMM is detected at the correct speed after installation?

Enter the BIOS or UEFI on your ThinkAgile VX3320, VX3520-G, VX5520, VX7320-N or VX7520 and verify the memory shows as 16GB, 2933MHz (PC4-23400), CL21, 1.2V and ECC Registered.

What ships with the OWC 2R9D42R816GB module and what must be sourced separately?

The box contains one 16GB 288-pin DDR4 ECC Registered RDIMM (2Rx8). No cables, tools or additional DIMMs are included; purchase extra modules if your server requires a matched pair or larger total capacity.

Which OWC DDR4 ECC RDIMM capacity should I choose for a Lenovo ThinkAgile VX5520 upgrade?

This listing is the 16GB 2933MHz CL21 1.2V 2Rx8 Registered DIMM (part 2R9D42R816GB). Select it when you need a single 16GB module; add multiple units to reach your desired total memory.
