64GB DDR4 2933MHz ECC Registered RDIMM

This 64GB DDR4 module runs at 2933MHz with CL21 latency and 1.2V operation. It uses a 288-pin registered DIMM form factor with ECC for data integrity. The dual-rank 2Rx4 design targets Lenovo ThinkAgile servers built on Xeon SP Gen 2 platforms.

Registered ECC requires compatible server platform

Registered ECC memory only works in server and workstation chipsets that support buffered signalling and error correction. It will not function in standard desktop motherboards and cannot be mixed with unbuffered DIMMs. The module also steps down to 2133MHz, 2400MHz or 2666MHz when the system bus requires lower speeds.

Single 64GB dual-rank module per slot

Each stick delivers 64GB in a 2Rx4 organisation, so capacity scales with the number of populated slots. Buyers needing smaller increments or unbuffered memory for desktop platforms should look elsewhere. The part replaces Lenovo numbers 4X70V98063, 4ZC7A08710 and 4ZC7A08744.

Klausimai apie šią prekę

Should I choose the 64 GB module or a different capacity for my ThinkAgile server?

This listing provides a single 64 GB DDR4 2933 MHz CL21 ECC registered DIMM. Match the total capacity to your workload and the number of available slots in the HX or VX model you are upgrading.

What does the 2933 MHz rating mean once the module is installed in a ThinkAgile HX7521?

The module will run at up to 2933 MHz with CL21 latency at 1.2 V. If the platform operates at a lower memory speed it will automatically down-clock to 2666 MHz, 2400 MHz or 2133 MHz while keeping ECC and registered operation.

Is the DDR4 PC4-23400 interface compatible with standard desktop memory slots?

No. This is a 288-pin ECC registered RDIMM for servers and workstations. It will not fit or function in consumer desktop boards that require unbuffered non-ECC UDIMMs.
