OWC 128GB DDR4 ECC RDIMM kit

This kit provides 128GB of DDR4 memory as four 32GB registered ECC modules rated at 3200 MT/s with CL22 latency. It is built specifically for the Dell PowerEdge XE8545 server and operates at 1.2V. The modules use a 2Rx4 organisation and a 288-pin form factor.

Registered ECC design for server stability

Registered ECC memory adds a buffer and error correction that standard desktop DIMMs lack, so data integrity is maintained under heavy workloads. The kit replaces Dell part numbers such as 370AEVN and 75X1V. Mixing these modules with unbuffered or load-reduced memory is not supported.

Verify slot count and memory mode

Confirm the XE8545 has at least four free DDR4 slots and that the system BIOS is configured for registered ECC operation. The platform must support 2Rx4 modules at 3200 MT/s; otherwise the kit will not function.

Questions about this item

Will the 288-pin DDR4 RDIMMs need any periodic cleaning or component replacement?

No moving parts or user-serviceable components exist on these modules; the 288-pin DDR4 RDIMMs are solid-state and require no scheduled maintenance.

What limits sustained throughput first — the CL22 latency or the 3200 MT/s bus?

The 3200 MT/s data rate caps peak bandwidth; CL22 timing adds fixed access delay but does not reduce the maximum transfer ceiling.

How much heat and power does the 1.2 V 128 GB kit produce when the PowerEdge XE8545 runs continuously?

Each 32 GB 2Rx4 module draws 1.2 V with no heat spreader, so total kit power scales with all four DIMMs active under load.
