Dell-Compatible 8GB DDR4 RDIMM

This 8GB registered DDR4 module runs at 2133 MT/s with CL15 latency and 1.20 V operation. It uses a 2Rx8 organisation and ECC error correction for data integrity in server workloads. The 288-pin RDIMM form factor matches Dell part A7946644 and is built with major-brand DRAM chips.

Suited for Dell servers needing ECC registered

Ideal for administrators expanding capacity in compatible Dell platforms that require registered ECC DDR4 at this speed and rank configuration. Not suitable for systems that accept only unbuffered UDIMMs, for boards limited to higher or lower data rates, or for builds needing larger single-module capacities.

Straightforward DIMM installation

Align the notch with the slot key, press firmly until the retention clips engage, then verify the module is recognised in BIOS. Common issues include mixing registered and unbuffered DIMMs in the same channel, populating slots in an unsupported sequence, or exceeding the platform's maximum supported capacity per channel.

Questions about this item

Does my server need a 288-pin DDR4 slot to use this 8 GB RDIMM?

Yes — the module is a 288-pin DDR4 RDIMM, so the motherboard must provide a DDR4 DIMM slot that accepts registered memory.

Can I mix this CL15 registered stick with older unbuffered DDR4 modules I already have?

No — registered and unbuffered DDR4 cannot be mixed on the same channel; the system will not post if both types are installed together.

How do I confirm the stick is running at 2133 MT/s after installation?

Check the memory speed reported in the BIOS or an OS tool such as dmidecode; it should show DDR4-2133 (PC4-17000) with CL15 timings.
