Brute Networks
16 GB DDR4-2666 ECC registered RDIMM with CL15 latency and 1.2 V operation, matching Dell part SNPDFK3YC/16G for compatible servers
This 16GB DDR4 module runs at 2666 MT/s with CL15 latency and 1.2V operation. It is built as a registered ECC RDIMM using a 2Rx8 organisation on a 288-pin form factor. The part matches Dell part number SNPDFK3YC/16G and is intended for servers that require registered error-correcting memory.
Registered buffering reduces electrical load on the server memory controller, allowing higher capacities per channel. ECC circuitry detects and corrects single-bit errors to protect data integrity. Modules use Samsung, SK Hynix or Micron components that meet or exceed OEM specifications. The 288-pin DDR4 interface fits standard server DIMM slots.
Brute Networks modules are sourced from the same major-brand manufacturers that supply OEM-branded parts, so installing them does not void the original server warranty. Lifetime warranty coverage is included with the module. Buyers who need non-ECC unbuffered DIMMs or speeds beyond DDR4-2666 cannot use this part.
