16 GB DDR4 ECC RDIMM for Lenovo ThinkAgile

This 16 GB DDR4 2666 MHz ECC registered DIMM is built for Lenovo ThinkAgile servers running Xeon SP Gen 1 processors. It targets administrators expanding memory in VX3720, VX5520, VX7320-N or VS7520 nodes. The module is not compatible with standard desktop computers or unbuffered memory configurations.

288-pin DIMM installs in server slots

Installation follows standard 288-pin RDIMM procedure: power down the node, open the chassis, align the key notch and press until the latches lock. The most common issue is mixing registered DIMMs with unbuffered modules, which prevents the system from posting. Verify that all populated slots use registered ECC memory before booting.

Check ThinkAgile model and existing DIMM type

Confirm the server is one of the four listed ThinkAgile models and that the current memory population uses registered ECC RDIMMs. The module runs at 1.2 V and is backward compatible with 2133 MHz and 2400 MHz bus speeds. It replaces Lenovo part numbers 01AG618, 4X70P98202 and 7X77A01303.

Questions about this item

How can I confirm the 288-pin DDR4 ECC RDIMM is running at 2666MHz CL19 after installation?

Check the memory speed and timings in the server BIOS or UEFI; the module should report 2666MHz and CL19 at 1.2V.

What comes in the package and do I need any extra components for the ThinkAgile VX3720?

The package contains the 16GB 2Rx8 registered DIMM only; no cables, brackets or additional parts are required for the listed ThinkAgile models.

Which capacity should I choose if I want to match the Lenovo part numbers 01AG618, 4X70P98202 and 7X77A01303?

This 16GB module directly replaces those Lenovo part numbers, so select the 16GB version for a like-for-like upgrade.
