Brute Networks 16GB DDR4-2666 Registered ECC RDIMM

This 16GB DDR4 module runs at 2666MHz with CL15 latency and 1.2V operation. It uses a 288-pin registered design with ECC and a single-rank 1Rx4 organisation. The part matches HP part number 840757-191 and uses major-brand chips from Samsung, SK Hynix or Micron.

For servers needing HP-compatible registered ECC

Suits administrators expanding capacity in systems that require DDR4-2666 registered ECC RDIMMs with 1Rx4 ranking. Not for workstations or desktops that accept only unbuffered non-ECC UDIMMs. Buyers who need higher speeds, larger densities, different rank configurations or laptop SO-DIMM form factors should look elsewhere.

1Rx4 registered ECC at DDR4-2666 decides fit

The single-rank 1Rx4 registered ECC organisation at 2666MHz determines whether the module works in your server. Verify that your platform supports registered ECC RDIMMs with this exact rank and speed before purchase.

Domande su questo articolo

Does the CL15 latency of this DDR4 2666 module become the first bottleneck during sustained heavy workloads?

CL15 latency is the rated timing at 2666 MT/s; under sustained heavy workloads the memory controller and bus bandwidth typically limit throughput before CAS latency does.

How much heat and power does a 1.2 V registered ECC DIMM add when running all day in a server?

At 1.2 V the module draws low power and generates modest heat; registered buffering adds negligible overhead, so a standard server airflow path handles it without extra cooling.

What server memory slot and chipset support must I already have for this 288-pin RDIMM to work?

You need a DDR4 288-pin RDIMM slot on a platform that supports registered ECC memory; the module follows JEDEC DDR4 2666 specifications for compatible chipsets.
