512GB DDR5 ECC Registered Kit
This 512GB kit contains four 128GB DDR5 4800MHz RDIMMs built for Dell PowerEdge R7615 rack servers. Each module runs at 1.1V with CL40 latency and uses a 4Rx4 organisation. The registered design adds a buffer that stabilises heavy memory loads in multi-socket platforms.
Suited for high-density virtualisation
Administrators expanding a R7615 to its maximum supported capacity will match the factory configuration exactly. Systems that require unbuffered UDIMMs, non-ECC memory or speeds beyond 4800MHz cannot use this kit.
Sustained load behaviour
Registered buffering and on-die ECC keep error rates low during continuous throughput workloads such as in-memory analytics or container clusters. The 1.1V operating voltage limits thermal output when all four channels are saturated for extended periods.

Questions about this item
What motherboard slot and voltage are required for the 288-pin DDR5 1.1V RDIMMs?
The kit uses 288-pin DDR5 RDIMM modules running at 1.1V; the motherboard must provide DDR5 RDIMM slots at that voltage.
Will the 4Rx4 registered modules work with other registered DDR5 DIMMs already in the server?
Yes, the 4Rx4 registered DDR5 4800 modules can operate alongside other registered DDR5 DIMMs if the platform supports mixed rank populations.
How can I verify the 512GB kit is running at PC5-38400 CL40 after installation?
Check the system BIOS or OS memory report for 4800 MT/s speed, CL40 latency and the full 512GB capacity across all four slots.
