Lenovo ThinkAgile Xeon SP Gen 1 memory

This 32GB DDR4 2666MHz ECC Registered RDIMM is built for the Lenovo ThinkAgile platform running Xeon SP Gen 1 processors. It delivers 32GB of capacity at PC4-21300 speed with CL19 latency and 1.2V operation. The 2Rx4 dual-rank layout fits 288-pin server DIMM slots.

ECC Registered changes compatibility

The module uses ECC Registered technology required by workstation and server boards. It will not work in standard desktop systems and cannot be mixed with unbuffered memory. Backward compatibility covers 2133MHz and 2400MHz bus speeds. It replaces Lenovo part numbers 4X70P98203 and 7X77A01304.

Suited for ThinkAgile upgrades; not for desktops

This DIMM suits administrators extending ThinkAgile Xeon SP Gen 1 servers or building compatible replacements. Buyers needing memory for consumer motherboards, laptops or non-ECC platforms should look elsewhere. Systems requiring unbuffered or load-reduced modules are also unsupported.

Questions about this item

Will the 2Rx4 rank layout ever require replacement under normal server loads?

The 2Rx4 ECC registered module is built for continuous server operation; no scheduled replacement is needed unless a correctable error count exceeds platform thresholds.

What speed ceiling appears first when the module runs at full load in a ThinkAgile Xeon SP Gen 1 system?

The DDR4 2666 CL19 rating sets the maximum data rate; the memory controller will not push beyond PC4-21300 even under sustained workloads.

How much heat and power does the 1.2 V 288-pin DIMM generate during all-day operation?

At 1.2 V the module draws minimal power and, lacking a heat spreader, relies on chassis airflow to stay within JEDEC thermal limits.
