16GB DDR4 ECC Registered RDIMM

This 16GB DDR4 2933MHz CL21 module is built for Lenovo ThinkAgile HX1320 and HX1321 servers. It uses a 288-pin registered DIMM design with ECC error correction and operates at 1.2V. The 2Rx8 organisation suits multi-socket Xeon platforms that require registered memory.

Registered DIMM limits

Registered memory adds a buffer that reduces electrical load on the memory controller, allowing higher capacities per channel than unbuffered modules. This module cannot be mixed with unbuffered DIMMs and will not work in standard desktop boards that lack registered-memory support. Backward compatibility covers 2133MHz, 2400MHz and 2666MHz bus speeds.

Replaces Lenovo 01AG631

The module replaces Lenovo part numbers 01AG631, 4ZC7A08708 and 4ZC7A08741. The upgrade is worthwhile when expanding capacity in existing HX1320 or HX1321 nodes or when building new configurations that demand ECC registered DDR4 at 2933MHz. Buyers needing unbuffered memory or desktop compatibility should look elsewhere.

Perguntas sobre este artigo

Should I pick the 16GB module or a different capacity for my ThinkAgile HX1320?

This listing supplies a single 16GB RDIMM. Add one module per available slot or match the existing capacity in each channel for balanced performance.

What does the 2933MHz rating deliver once installed in a ThinkAgile HX1320?

The module runs at 2933MHz CL21 at 1.2V. The server's memory controller sets the final speed, so it will operate at the highest common frequency supported by the CPU and populated slots.

Is the 288-pin DDR4 ECC Registered interface compatible with my HX1321?

Yes. The 288-pin DDR4 ECC Registered RDIMM matches the HX1320 and HX1321 memory slots. It also down-clocks to 2666MHz, 2400MHz or 2133MHz if the system requires a lower speed.
