Server Memory Upgrade Kit

This OWC kit delivers 64GB of DDR4 3200 ECC Registered memory in two 32GB modules. It is built for the Dell PowerEdge XE8545 server platform and operates at 1.2V with CL22 latency. The modules use 288-pin RDIMM form factor with 2Rx4 organisation. They are designed for workloads that require error correction and registered buffering.

Suited For Enterprise Servers

This memory suits administrators upgrading or repairing a PowerEdge XE8545 that specifically requires registered ECC RDIMMs. It will not work in standard desktop PCs or consumer workstations that accept only unbuffered non-ECC modules. Buyers who need load-reduced ECC memory or unbuffered DIMMs for other platforms should look elsewhere.

Verify Server Requirements

Confirm your PowerEdge XE8545 supports DDR4 3200 registered ECC RDIMMs with 2Rx4 rank configuration. Check that all existing DIMMs match this capacity, speed and registered type to avoid mixing incompatible modules. Ensure the system firmware is current for full compatibility with the 64GB kit.

Questions about this item

Does my Dell PowerEdge XE8545 need to support ECC registered RDIMM memory for this 64GB kit to work?

Yes, the kit is 288-pin DDR4 ECC registered RDIMM; it only works in systems that accept registered ECC memory and will not function in standard desktop or unbuffered slots.

Can I add these two 32GB modules alongside existing DDR4 3200 unbuffered DIMMs in the same server?

No, registered ECC modules cannot be mixed with unbuffered or load-reduced memory; all installed DIMMs must be the same registered ECC type.

How can I verify the kit is running at DDR4 3200 CL22 after installation?

Check the BIOS memory information or OS tools such as dmidecode; they should report 3200 MT/s speed, CL22 latency and registered ECC status for each 32GB module.
