Dell PowerEdge HS5610 HS5620 memory kit

This 512 GB kit contains four 128 GB DDR5 4800 ECC registered RDIMMs built for Dell PowerEdge HS5610 and HS5620 servers. It runs at 1.1 V with CL40 latency and a 4Rx4 organisation. The modules are JEDEC compliant and carry no heat spreader. They are intended for workstation, server and NAS platforms that require registered ECC memory.

Installing registered ECC RDIMMs

Installation follows standard 288-pin DIMM procedure: power down, open the chassis, align the notch and press until the latches click. The kit will not work in standard desktop boards that accept only unbuffered memory. Mixing these registered modules with unbuffered or load-reduced ECC DIMMs is unsupported and will prevent boot. No extra tools or firmware steps are required beyond the server’s normal memory configuration utility.

Suited for Dell PowerEdge HS5610 and HS5620 upgrades

This kit suits administrators expanding memory in the listed PowerEdge models or building new configurations that specify DDR5 4800 registered ECC. It is not for desktop PCs, laptops or any system that requires unbuffered or load-reduced memory. Buyers needing different capacities, speeds or form factors should look at other system-specific kits.
