Eight 64 GB DDR5 ECC registered DIMMs deliver 512 GB at 4800 MHz with CL40 latency and 1.10 V operation
Capacity 512GB (8 x 64GB)
This kit provides 512GB of DDR5 memory across eight 64GB registered DIMMs. It is built for servers and workstations that require ECC error correction and registered signal buffering. The modules run at 4800 MHz with CL40 latency and 1.1V operation. Desktop and laptop systems cannot use this memory.
Each module fits a standard 288-pin DDR5 DIMM slot and installs with a single keyed insertion. Server platforms often require specific slot population rules per channel; the system manual must be followed to avoid boot failure. Mixing ranks or skipping required slots are the most common causes of unrecognised capacity or stability errors.
The DDR5 4800 standard caps transfer rates at this frequency, so bandwidth scales only by adding channels or modules. Registered buffering adds one clock cycle of latency versus unbuffered memory, which slightly reduces single-thread responsiveness. ECC overhead also reserves a portion of each burst for parity, lowering usable throughput compared to non-ECC configurations.

Other versions of this model
Same family, different memory, cooler or clock — compare before you commit.
Check the BIOS or UEFI memory information screen; it should report 4800 MT/s speed and CAS latency 40 for each of the eight 64 GB modules.
The box contains eight 64 GB DDR5 288-pin RDIMMs totalling 512 GB; no cables, brackets or additional hardware are included.
Select this 512 GB kit when your platform supports eight registered ECC modules at 1.1 V and you need the full 512 GB capacity; otherwise pick a smaller kit matching your slot count.
