System-specific ECC RDIMM for Lenovo ThinkAgile

This 16GB DDR4 2666 CL19 registered DIMM is built for Lenovo ThinkAgile HX7520, HX7521, HX7820, HX7821 and NX2320 servers running Xeon SP Gen 1 processors. It delivers error-correcting, buffered memory for workloads that require data integrity and sustained uptime. The module operates at 1.2V and conforms to the PC4-21300 standard.

Compatibility checks before ordering

Verify that your ThinkAgile chassis lists one of the five supported model numbers and that the memory slots accept 288-pin registered ECC RDIMMs. This memory cannot be mixed with unbuffered DIMMs and will not function in standard desktop or consumer platforms. Confirm the system firmware is current enough to recognise 2Rx8 16GB modules at 2666MHz.

Replaces Lenovo 01AG618 4X70P98202 7X77A01303

The module directly replaces Lenovo part numbers 01AG618, 4X70P98202 and 7X77A01303. It is a worthwhile jump when expanding capacity beyond the factory configuration or when refreshing older 2133MHz and 2400MHz DIMMs to a uniform 2666MHz speed across all channels. Builders who need unbuffered memory or higher-density modules should look elsewhere.

Preguntas sobre este artículo

Does the module ship as a single 16GB stick or do I need to order a kit?

The listing is for one 16GB DDR4 2666 ECC RDIMM module; add multiple units to reach your desired capacity.

Should I choose the 2666MHz CL19 version or a lower-speed alternative for my ThinkAgile HX7520?

The 2666MHz CL19 module is the specified speed; it also runs at 2400MHz and 2133MHz if the system requires it.

What does the 2666MHz PC4-21300 rating deliver in a live ThinkAgile HX7821 server?

It provides 2666 MT/s bandwidth at CL19 latency with ECC error correction for registered server workloads.
