16 GB DDR4 Load-Reduced ECC module
This 16 GB DDR4 module runs at 2666 MT/s with CL19 latency and 1.20 V operation. It uses a 2Rx8 load-reduced registered design with Chipkill ECC for error correction. The 288-pin DIMM is sold as a single stick from a quad-channel kit. It suits servers that require registered memory with reduced electrical load.
Load-reduced registered DDR4 constraints
Load-reduced DIMMs buffer both address and data lines, lowering the electrical load on the memory controller compared with standard registered modules. The DDR4 2666 interface caps bandwidth at the PC4-21300 rate, so throughput cannot exceed that ceiling. Mixing load-reduced sticks with standard registered or unbuffered DIMMs is not supported by the memory controller. Chipkill ECC corrects multi-bit errors but adds latency versus non-ECC memory.
Single-stick installation notes
Install the 288-pin module into a DDR4 RDIMM/LRDIMM slot aligned with the key notch; the load-reduced design does not change the physical insertion force. Systems must be configured for load-reduced memory in the BIOS or the module will not train at 2666 MT/s. A common issue is populating slots in the wrong order for quad-channel operation, which forces the controller to fall back to single-channel mode. Another issue is leaving ECC scrubbing disabled, so corrected errors are not logged.

Ερωτήσεις για αυτό το προϊόν
Should I pick the 16 GB 2Rx8 load-reduced module or a smaller single-rank stick?
The 16 GB 2Rx8 load-reduced design lets a server populate many slots without overloading the memory controller, so choose it when you need maximum capacity per channel.
What does the 2666 MT/s rating deliver inside a server?
The DDR4 2666 speed provides 21300 MB/s peak bandwidth per module, giving each core steady throughput for virtualisation and database workloads.
How does the load-reduced DDR4 288-pin interface affect real-world limits?
Load-reduced buffering reduces electrical load on the bus, allowing higher total system memory than standard registered DIMMs while keeping the same 1.20 V operation.
