256GB DDR5 5600 ECC RDIMM kit
This NEMIX RAM kit supplies 256GB across four 64GB registered DDR5 modules rated at 5600 MT/s with CL46 latency. It is built for the Lenovo ThinkSystem SR780a V3 rack server and carries ECC protection for data integrity in enterprise workloads. The modules run at 1.1V and use a 2Rx4 organisation on a 288-pin form factor. Buyers needing non-ECC memory or consumer DIMM slots cannot use this kit.
Installation and common issues
The modules are keyed 288-pin DDR5 RDIMMs that seat in the server’s registered DIMM slots; alignment is straightforward when the ejector levers are open. Because the kit is registered and ECC, the system BIOS must support registered memory or the server will not post. Mixing these sticks with unbuffered or different-rank modules typically causes boot failure or reduced stability. Always follow the Lenovo service guide for population order and firmware updates.
DDR5 RDIMM practical limits
DDR5 RDIMM topology relies on the memory controller’s registered clock driver, so maximum capacity and speed depend on the CPU’s supported ranks per channel. The 2Rx4 organisation counts as two ranks per module, which can limit the number of DIMMs per channel at the rated 5600 MT/s. Voltage is fixed at 1.1V, so no manual over-voltage tuning is available on locked server platforms.

Vprašanja o tem izdelku
How can I confirm the kit is running at DDR5 5600 CL46 after installation?
Check the memory speed and timings in the server BIOS or a tool like CPU-Z; the modules should report 5600 MT/s with CAS latency 46 at 1.1 V.
What is included in the package and do I need any extra parts?
The kit contains four 64 GB DDR5 5600 ECC RDIMM modules for a total of 256 GB; no additional components are required for installation in a compatible Lenovo ThinkSystem SR780a V3.
Which capacity version should I choose for the Lenovo SR780a V3?
This kit provides 256 GB as four 64 GB RDIMMs; select it when your configuration calls for that exact capacity and 2Rx4 registered ECC layout.
