512 GB DDR5 ECC RDIMM kit

This kit provides 512 GB of DDR5 memory across eight 64 GB registered DIMMs. It is built for workstations and servers that require error-correcting code and registered buffering. Standard desktop platforms cannot use this memory. It is not for systems that only accept unbuffered or load-reduced modules.

Sustained 5200 MT/s operation

The modules run at 5200 MT/s with a CAS latency of 42 at 1.1 V. JEDEC-standard timings keep performance stable during extended workloads. Registered buffering reduces electrical load on the memory controller. ECC corrects single-bit errors to protect data integrity over long runs.

Verify registered DIMM support

Confirm the motherboard or system accepts 288-pin DDR5 ECC registered DIMMs. Check that the platform supports 2Rx4 rank organisation and 1.1 V operation. Ensure the memory controller can address 512 GB total capacity across eight slots. Do not mix with unbuffered or load-reduced memory.

Questions sur cet article

How much power does the 1.1 V DDR5 kit draw when the server runs continuously?

Each 64 GB module operates at the JEDEC-standard 1.1 V, so the eight-module kit runs at the same voltage as any compliant DDR5 5200 registered DIMM.

Does my motherboard need DDR5 slots and a registered-DIMM memory controller to use this 512 GB kit?

The kit requires a platform with 288-pin DDR5 RDIMM slots that support ECC registered memory; standard desktop boards without a registered controller will not accept it.

Can I mix these 2Rx4 registered modules with load-reduced or unbuffered DIMMs already in my system?

OWC states the modules cannot be mixed with unbuffered or ECC load-reduced memory; all slots must use registered ECC DIMMs for the kit to function.
