Dual 32 GB DDR5 4800 CL40 ECC registered RDIMMs for Dell PowerEdge HS5610 and HS5620 servers
Capacity 64GB (2 x 32GB)
This OWC kit supplies 64GB of DDR5 4800 ECC registered RDIMM across two 32GB modules. It is built for Dell PowerEdge HS5610 and HS5620 servers that require registered memory with error correction. The modules run at 1.1V with CL40 latency and a 2Rx8 rank structure. They will not work in standard desktop computers or alongside unbuffered or load-reduced DIMMs.
Replacing smaller registered DIMMs with this 64GB kit increases total memory without changing the memory type your server expects. The jump is worth it when workloads exceed the capacity of the existing modules and the platform supports the full 4800 speed. Mixing with unbuffered or load-reduced memory is not supported, so all slots must use the same registered ECC specification.
Each 288-pin module seats in the server's standard DDR5 RDIMM slots with no extra tools. The most common issue is mixing registered ECC with unbuffered or load-reduced DIMMs, which prevents the system from posting. Confirm every populated slot uses identical registered ECC modules before powering on.

Yes. These 288-pin DDR5 ECC Registered DIMMs are built to the JEDEC standard for the PowerEdge HS5610 and HS5620, so they seat directly in the server's DDR5 RDIMM slots.
Power down the server, open the chassis, align each module's notch with the slot key, and press firmly until both retention clips lock. The step often missed is seating both modules in the correct channel pair so the memory controller sees the full 64 GB at 4800 MT/s.
The modules have no moving parts and no heat spreader, so they require no routine maintenance. Replace them only if a memory diagnostic reports uncorrectable ECC errors or if you upgrade to a higher capacity kit.
