Server-Specific ECC RDIMM Kit

This 512GB kit contains eight 64GB DDR4 3200 CL22 registered ECC modules built for the Dell PowerEdge XE8545. It is intended for administrators upgrading or repairing that specific server platform. Standard desktop systems cannot use registered ECC DIMMs and will not accept these modules.

Pre-Validated Eight-Module Set

The kit delivers a matched population of eight identical 2Rx4 DIMMs so the server can be filled in a single step without mixing ranks or speeds. Each module is tested to JEDEC PC4-25600 specifications at 1.2V, removing the trial-and-error phase of sourcing individual sticks.

Registered ECC Requirement

Only systems that require DDR4 288-pin registered ECC memory with a CL22 latency profile can use this kit. Buyers whose platforms need unbuffered ECC, load-reduced DIMMs, or a different DDR generation cannot install these modules.

Questions about this item

What maintenance or replacement will the 512 GB DDR4 3200 CL22 ECC RDIMM kit need later?

The modules have no heat spreader and run at 1.2 V, so the only routine maintenance is keeping server airflow clear; no user-serviceable parts exist on the DIMMs themselves.

What limit shows up first when the 8×64 GB registered DIMMs run sustained workloads in the XE8545?

The first limit is the DDR4 3200 CL22 bandwidth ceiling of the memory controller; once all channels are saturated, latency and throughput cannot exceed the JEDEC PC4-25600 specification.

How much noise, heat or power does the 288-pin 2Rx4 kit produce when running all day?

Each 64 GB module operates at 1.2 V with no onboard cooling, so heat output is low and silent; total power draw scales with the eight DIMMs but stays within standard registered DDR4 thermal limits.
