Server ECC RDIMM upgrade

This 32GB DDR4 module is built for the PowerEdge XE8545 and other systems that require registered ECC memory. It runs at 3200 MT/s with CL22 latency at 1.2V and uses a 288-pin 2Rx4 layout without a heat spreader. The stick is designed for server and workstation platforms that support registered DIMMs.

Not for desktop or unbuffered builds

Buyers who need memory for a standard desktop, laptop or consumer motherboard cannot use this module because it is registered ECC and will not function in unbuffered slots. It also cannot be mixed with unbuffered or load-reduced ECC DIMMs in the same system. Builders who require a different capacity, speed or rank configuration should look at other qualified parts.

Single 32GB module headroom

One module adds 32GB of registered ECC capacity, suitable for expanding a compatible server that has free 288-pin slots and supports DDR4 3200 registered memory. Total capacity and maximum speed depend on the platform's memory controller, slot count and qualified vendor list. Systems that require load-reduced DIMMs or a different rank structure will not accept this module.

Questions about this item

What server model must I already have for this 288-pin DDR4 3200 ECC RDIMM to work?

The module is validated for the PowerEdge XE8545; install it only in that system or in another server whose qualified-vendor list includes this exact part.

Can I keep my existing unbuffered or load-reduced DIMMs and add this registered 2Rx4 stick?

No — registered ECC memory cannot be mixed with unbuffered or load-reduced modules; all slots must use the same registered ECC type.

How do I verify the module is running at PC4-25600 CL22 after installation?

Check the BIOS memory information or run a tool such as dmidecode; it should report 3200 MT/s, CAS 22, 1.2 V and registered ECC status.
