32 GB DDR4-2666 ECC Registered RDIMM

This 32 GB DDR4-2666 module is an ECC registered RDIMM built for Dell servers that accept the TN78Y part number. It runs at 1.2 V with a CAS latency of CL15 and uses a 2Rx4 rank configuration on a 288-pin interface. The module is designed to maximise installed memory capacity in compatible rack or tower systems.

Suited for administrators expanding Dell servers

This memory suits IT teams who need to increase virtual-machine density or eliminate paging on existing Dell platforms that require registered ECC DDR4 at 2666 MT/s. It is not for workstations or desktops that only accept unbuffered non-ECC modules, nor for systems that demand a different voltage, rank layout or speed grade.

Verify slot count, maximum capacity

Before ordering, confirm the server’s qualified-vendor list includes the TN78Y equivalent and that free 288-pin RDIMM slots are available. Check the platform’s maximum supported memory per socket and any required population order for 2Rx4 registered modules to ensure the upgrade will be recognised at full speed.

Questions about this item

Will this 288-pin DDR4 RDIMM fit a Dell server that requires the TN78Y part number?

Yes, the module is built to the Dell TN78Y specification — 32GB, DDR4-2666, 2Rx4, CL15, 1.20V, ECC registered — so it matches the pin-out, voltage and timings that the original part provides.

Does the registered buffer on this stick prevent it from working in a system that currently uses unbuffered UDIMMs?

Registered and unbuffered DIMMs cannot be mixed; the memory controller must support registered modules, so the server must already be designed for RDIMMs.

After installation, how can I confirm the module is running at the rated DDR4-2666 speed and CL15 latency?

Check the BIOS memory information or a tool such as CPU-Z; it should report 2666 MT/s, CAS 15, 1.20V and ECC active for the new DIMM.
