128GB DDR4 3200 ECC RDIMM kit

This 128GB kit contains eight 16GB DDR4 3200 registered DIMMs with ECC and a CL22 latency. It operates at 1.2V and uses a 288-pin 2Rx8 layout built with major OEM chips. The modules are designed for Dell EMC PowerEdge XE7100, XE7420 and XE7440 rack servers.

Suited for Dell PowerEdge XE server upgrades

IT teams expanding memory in the listed Dell EMC PowerEdge models will find this kit validated for those platforms. Systems that require unbuffered UDIMMs, non-ECC memory or a different pin count cannot use these registered ECC modules. Buyers needing higher speeds or lower latencies should look elsewhere.

Eight-module kit fills eight slots for 128GB total

The 128GB capacity handles virtualisation, database and compute workloads that benefit from large registered memory pools. Each 16GB dual-rank module contributes to the total while the CL22 timing and 3200 MT/s rate set the throughput ceiling. Workloads demanding faster data rates or greater per-module density will exceed this kit's headroom.

Questions about this item

Does this kit require a server motherboard with 288-pin DDR4 RDIMM slots?

Yes, the 128GB kit uses 288-pin DDR4 RDIMM modules that need registered DIMM slots on a compatible server board.

Can I mix these 3200 CL22 modules with slower DDR4 RDIMMs already installed?

The system will run all modules at the speed of the slowest kit, so existing slower RDIMMs will limit the 3200MHz rating.

How do I confirm the ECC registered memory is active after installation?

Check the BIOS memory information screen — it should show 128GB total, ECC enabled, and registered mode at 3200MHz CL22.
