A-Tech 16GB DDR4-2133 ECC UDIMM 2Rx8 CL15 288-Pin Server RAM

SKU CH-KB7G-DSF8G

16 GB DDR4 ECC unbuffered DIMM at 2133 MHz with CL15 latency for servers and workstations

  • CAS latencyCL15
  • Memory rank2Rx8
  • Product type288-Pin DDR4 SDRAM
  • ECC protection guards data integrity in servers
  • 16 GB DDR4 module runs at 2133 MHz
  • Dual-rank 2Rx8 layout increases memory density
  • Standard 1.2 V DDR4 voltage lowers power draw
  • 288-pin UDIMM fits compatible server and workstation boards

Target Server Memory

This 16 GB DDR4 ECC UDIMM module is built for servers and workstations that require error-correcting unbuffered memory. The dual-rank 2Rx8 organisation and CL15 timing suit platforms qualified for DDR4-2133 operation. Desktop and laptop systems cannot use this module.

Standard Voltage Operation

The stick runs at the DDR4 standard 1.2 V, so power draw and heat output remain within normal limits for registered server DIMMs. No additional cooling or voltage adjustments are needed when the host platform supports the rated speed.

Tested Reliability

Every unit undergoes quality-assurance testing before shipment to verify dependable performance in compatible systems. A lifetime warranty and US-based technical support are included for the life of the product.

Questions about this item

How do I install the 288-pin DDR4 ECC UDIMM and what step is often missed?

Align the notch on the module with the slot key, press firmly until both retention clips click, then verify in BIOS that the 2133 MHz speed and ECC function are recognised; the missed step is checking the motherboard manual for the correct channel population order for dual-rank 2Rx8 modules.

What maintenance or replacement will this 16GB module need over time?

No scheduled maintenance is required; keep the server interior dust-free to maintain airflow around the 1.2V DIMMs, and replace the module only if memory diagnostics report correctable ECC errors rising above the platform threshold.

What limit appears first when this dual-rank 2Rx8 kit runs sustained workloads?

The CL15 latency at 2133 MHz sets the bandwidth ceiling; under continuous load the memory controller will hit its maximum throughput before thermal throttling becomes a factor on these 1.2V unbuffered DIMMs.
