8GB DDR4-2666 ECC UDIMM with CL15 timing and 1.2V operation for compatible Dell servers
This 8GB DDR4-2666 ECC UDIMM is built for Dell servers and workstations that require error-correcting memory. It suits administrators who need to maintain data integrity on supported platforms without replacing entire systems. The module is new and validated for 100% Dell compatibility.
The unregistered 1Rx8 stick fits a standard DDR4 UDIMM slot on compatible Dell motherboards and runs at 1.20V. It frees an additional slot for future expansion while delivering PC4-21300 bandwidth. Buyers who need registered or load-reduced DIMMs should select a different module type.
CL15 latency and major-brand chips from Samsung, SK Hynix or Micron provide steady throughput during extended workloads. The ECC function corrects single-bit errors continuously, helping prevent silent data corruption over long uptimes. Modules are supplied as identically matched sets to avoid timing mismatches.

The module runs at CL15 CAS latency, which is the timing constraint that appears first during continuous memory-intensive work.
At 1.20 V the stick draws minimal power and runs cool enough for passive server airflow, with no active cooling required on the module itself.
The board needs an unbuffered DDR4 slot that supports ECC UDIMMs at 2666 MT/s and 1.20 V operation.
