32GB DDR4 ECC RDIMM for Lenovo ThinkAgile

This 32GB DDR4 2933MHz ECC registered DIMM is built for Lenovo ThinkAgile servers based on Xeon SP Gen 2 processors. It delivers error-correcting memory for HX7521, HX7820, HX7821, VX 1U and VX2320 models. The module runs at 1.2V with CL21 latency and a 2Rx4 organisation.

Check compatibility before ordering

Verify that your ThinkAgile system accepts 288-pin DDR4 ECC registered memory and that no unbuffered DIMMs are already installed. Mixing registered and unbuffered modules is not supported. The platform must operate at 1.2V and the memory controller should support 2933MHz or lower speeds such as 2666MHz, 2400MHz or 2133MHz.

Suits ThinkAgile upgrades, not desktops

This module suits administrators expanding memory in the listed ThinkAgile servers or replacing Lenovo parts 01AG632, 4ZC7A08709 and 4ZC7A08742. It is not for standard desktop PCs, laptops or workstations that require unbuffered non-ECC memory. Builders needing unbuffered DIMMs or consumer SODIMMs should look elsewhere.

Questions about this item

Does the 288-pin DDR4 RDIMM arrive as a single 32GB module or do I need to order anything else?

The package contains one 32GB OWC DDR4 2933MHz ECC Registered RDIMM; no additional parts are required for installation.

Should I pick the 2933MHz CL21 2Rx4 version or a different speed for my ThinkAgile HX7820?

This 2933MHz CL21 2Rx4 module is the specified match for the HX7820 and will also run at 2666MHz, 2400MHz or 2133MHz if the platform requires it.

What does the 2933MHz rating mean once the RDIMM is installed in a Xeon SP Gen 2 server?

The module operates at up to 2933MHz with CL21 latency at 1.2V, delivering ECC Registered performance validated for the listed ThinkAgile models.
