128GB DDR4 ECC Registered RDIMM for Lenovo

This 128GB DDR4 2933MHz CL21 module is built for Lenovo ThinkAgile VX servers running second-generation Xeon Scalable processors. It targets administrators who need high-capacity, error-correcting memory to support virtualisation workloads or large datasets in the listed VX3320, VX3520-G, VX5520, VX7320-N and VX7520 platforms.

Compatibility and configuration checks before

Verify that the target server currently uses registered ECC DDR4 RDIMMs, because this module will not work in systems that require unbuffered memory. Confirm the motherboard has a free 288-pin DDR4 slot and that the existing memory population rules allow a 4Rx4 rank configuration. The stick operates at 1.2V and is backward compatible with 2133MHz, 2400MHz and 2666MHz bus speeds if the platform requires a lower frequency.

Integration into a server build

The registered design places a buffer on the command bus, reducing electrical load on the memory controller and allowing the platform to populate more slots per channel. ECC circuitry detects and corrects single-bit errors, protecting data integrity in always-on environments. With no heat spreader fitted, the module relies on the server’s directed airflow for cooling, leaving adjacent DIMM slots unobstructed for further capacity expansion.

商品問答

Does the 128GB module come alone or in a kit, and is any extra hardware needed?

This is a single 128GB 288-pin RDIMM. No cables, brackets or additional parts are required — just an available DDR4 slot in a compatible ThinkAgile server.

Should I choose the 2933MHz CL21 4Rx4 version or a different speed for my VX5520?

The 2933MHz CL21 4Rx4 module is the specified match for Xeon SP Gen 2 ThinkAgile models including the VX5520. It also runs at 2666MHz, 2400MHz or 2133MHz if the platform requires a lower speed.

What does the 2933MHz rating deliver once installed in a VX7520?

The module operates at up to 2933MHz with CL21 latency at 1.2V, providing ECC registered error correction and 4Rx4 organisation for maximum capacity per slot in the VX7520.
