Server-Specific DDR4 ECC Kit

This 128GB kit contains two 64GB DDR4 3200 registered DIMMs built for the PowerEdge XE8545. It targets administrators upgrading or repairing that exact server platform. The modules carry ECC and registered buffering for data integrity in multi-socket workloads. Standard desktop systems cannot use this memory.

Registered DDR4 Platform Constraints

Registered DIMMs require a server chipset that supports registered signalling; they will not function in consumer motherboards. Mixing these modules with unbuffered or load-reduced ECC memory is not supported. The 288-pin DDR4 form factor fits only DDR4-compatible server slots. Buyers needing memory for workstations without registered support should look elsewhere.

2Rx4 64GB Density per Module

Each DIMM uses a 2Rx4 organisation to deliver 64GB at DDR4 3200 CL22 1.2V. This density and rank configuration determines whether the XE8545 can populate all slots within its maximum supported capacity. Verify the server's qualified vendor list for 2Rx4 64GB RDIMMs before purchase.

Questions about this item

Should I choose the 128GB kit or a different capacity for my PowerEdge XE8545?

The kit supplies 128GB as two 64GB modules, matching the 2Rx4 registered ECC specification validated for the PowerEdge XE8545.

What does DDR4 3200 CL22 mean for real workloads on the XE8545?

The modules run at 3200 MT/s with CL22 timing, providing registered ECC bandwidth and latency tuned for the XE8545 memory controller.

Does the 288-pin RDIMM interface limit speed or capacity on the XE8545?

The 288-pin DDR4 RDIMM form factor is the required interface for the XE8545; it carries the 3200 MT/s signal and 64GB per module without reduction.
