16GB DDR4 2133 ECC Registered module

This 16GB DDR4 2133 module is built for servers and workstations that require error-correcting registered memory. It operates at PC4 17000 with a CAS latency of CL15 and a voltage of 1.20V. The 1Rx4 rank organisation suits dense multi-slot configurations.

288-pin registered DIMM without heat spreader

The 288-pin DDR4 form factor fits standard registered DIMM slots in compatible server platforms. Registered buffering reduces electrical load on the memory controller for stable operation across populated channels. The absence of a heat spreader keeps the profile low for tight chassis spacing.

ECC protection for data integrity

On-die ECC detects and corrects single-bit errors to maintain data accuracy in critical workloads. Registered signalling improves command timing margins in multi-module arrays. No additional accessories or software utilities are included with the module.

Otázky k tomuto produktu

What does the DDR4 2133 (PC4 17000) rating cap the data rate at in practice?

The module runs at 2133 MT/s, so the peak transfer rate is limited to the PC4 17000 bandwidth ceiling.

What physical slot and clearance does the 288-pin registered DIMM require?

It needs a standard 288-pin DDR4 DIMM socket; the module has no heat spreader, so it fits in tight server bays.

How is the 1Rx4 registered ECC module installed, and what step is often missed?

Align the notch with the keyed slot, press firmly until both retention clips click, then verify the BIOS recognises the ECC and registered mode.
