128GB DDR4 ECC RDIMM kit

This 128GB kit contains eight 16GB DDR4 2400 CL17 registered DIMMs built for Cisco HX220c M4 and HX240c M4 servers. It targets administrators who need to expand memory capacity in those specific platforms with validated ECC registered modules. The kit is not suitable for desktop PCs, workstations that require unbuffered memory, or systems that only accept load-reduced DIMMs.

Capacity headroom at 2400 MT/s

Eight ranks of 1Rx4 modules deliver 128GB total, allowing the supported Cisco servers to run larger virtualisation workloads and in-memory databases. Performance scales with the platform's maximum memory frequency of 2400 MT/s; workloads that demand higher throughput or lower latency than DDR4 2400 CL17 provides will not benefit from this kit.

Pre-validated module matching

Each 16GB DIMM is tested to match Cisco part numbers UCSMR1X161RVA and UCSMR1X161RVG, so the kit installs without manual qualification steps. The registered buffer and ECC function are verified for the target servers, eliminating compatibility guesswork. No heat spreaders are included, relying on the server's airflow design for thermal management.

商品問答

Will these 2400 MHz CL17 1Rx4 RDIMMs run alongside the DDR4 modules already in my HX220c M4?

These are 2400 MHz CL17 1Rx4 registered ECC RDIMMs. The server will clock all installed DIMMs to the speed of the slowest module, so existing DDR4 memory will operate at its rated speed or at 2400 MHz, whichever is lower.

How can I verify the kit is recognised at 2400 MHz CL17 with ECC active after installation?

Enter the BIOS or use a tool such as dmidecode or CPU-Z; each of the eight slots should show a 16 GB DDR4-2400 registered ECC DIMM with CL17 timings and 1.2 V operation.

Does the 128 GB kit include only the eight 16 GB RDIMMs, or are any cables or brackets supplied?

The package contains exactly eight 16 GB 288-pin DDR4-2400 CL17 1Rx4 registered ECC RDIMMs. No cables, brackets or additional hardware are included.
