64GB DDR4 ECC RDIMM for Lenovo ThinkAgile

This 64GB DDR4 2933MHz ECC registered DIMM is built for Lenovo ThinkAgile HX2320, HX2321, HX3320, HX3321 and HX3520-G servers. It targets administrators who need to expand memory capacity in these specific Xeon SP Gen 2 platforms. The module operates at 1.2V with CL21 latency and a 2Rx4 rank configuration.

DDR4 2933MHz registered ECC constraints

The DDR4 2933MHz registered ECC standard requires a server or workstation memory controller that supports registered modules. It will not function in standard desktop computers and cannot be mixed with unbuffered memory. Backward compatibility covers 2133MHz, 2400MHz and 2666MHz speeds, but the system will run all modules at the lowest common rate.

Tool-free DIMM installation with seating checks

Installation follows the standard 288-pin DIMM procedure: align the notch, press firmly until the retention clips click, and verify the module sits evenly. The most common issue is incomplete seating, which causes boot failures or memory errors. Because registered ECC modules cannot be mixed with unbuffered types, confirm every slot uses matching registered DIMMs before powering on.

Jautājumi par šo preci

Is this 64GB module the only capacity available for the ThinkAgile HX2320 HX2321 HX3320 HX3321 HX3520-G?

The listed part number 2R9D42R464GB is a single 64GB DDR4 2933MHz ECC Registered DIMM. Other capacities may exist under different part numbers but are not covered by this specific upgrade.

What does the 2933MHz speed rating deliver once installed in a ThinkAgile server?

The module runs at DDR4 2933 PC4-23400 with CL21 latency at 1.2V. In a compatible Xeon SP Gen 2 system it provides the rated bandwidth; if the platform operates at a lower memory speed the DIMM will downclock automatically.

Does the 288-pin RDIMM interface limit mixing with other memory types in these servers?

Yes. This is an ECC Registered 2Rx4 RDIMM. It cannot be mixed with unbuffered UDIMMs and requires a platform that supports registered memory, such as the listed ThinkAgile Xeon SP Gen 2 models.
