Lenovo ThinkAgile Xeon SP Gen 1 memory

This 16GB DDR4 2666MHz CL19 ECC Registered RDIMM is built for the Lenovo ThinkAgile Xeon SP Gen 1 platforms NX3321, VX 1U, VX2320, VX3320 and VX3520-G. It operates at 1.2V on a 288-pin interface with a 2Rx8 rank structure. The module replaces Lenovo part numbers 01AG618, 4X70P98202 and 7X77A01303. It is not compatible with standard desktop computers or unbuffered memory configurations.

Sustained server workload behaviour

ECC registered operation detects and corrects single-bit errors during continuous duty, protecting data integrity in virtualised and database tasks. The CL19 latency and 2666MHz speed maintain stable throughput under load, while backward compatibility with 2133MHz and 2400MHz systems allows deployment in mixed-speed channels. JEDEC and RoHS compliance ensure consistent electrical behaviour over time.

Upgrade path from older DDR4 RDIMMs

This module upgrades systems currently running lower-capacity or slower DDR4 ECC registered DIMMs within the supported ThinkAgile Xeon SP Gen 1 family. The jump is worth it when expanding memory capacity per slot or when replacing failed modules with a validated 16GB part. Buyers who need unbuffered memory or desktop compatibility cannot use this product.

Soalan tentang produk ini

How much power does the 1.2 V DDR4 2666 MHz CL19 module draw when running all day in a ThinkAgile server?

The module operates at 1.2 V and complies with JEDEC DDR4 specifications; exact power draw depends on the server workload and platform power management.

Which Lenovo ThinkAgile models must I already own for this 288-pin ECC registered RDIMM to work?

It is validated for ThinkAgile Xeon SP Gen 1 systems NX3321, VX 1U, VX2320, VX3320 and VX3520-G and replaces Lenovo part numbers 01AG618, 4X70P98202 and 7X77A01303.

Can I mix this 2Rx8 ECC registered stick with older 2133 MHz or 2400 MHz unbuffered DIMMs in the same server?

No — registered ECC memory cannot be mixed with unbuffered memory; the module is backward-compatible with 2133 MHz and 2400 MHz registered speeds only.
