16GB DDR4-2666 ECC UDIMM at CL15 and 1.2V for Dell AA101753 compatibility
This 16GB DDR4 module is built to match Dell part number AA101753 and delivers ECC error correction for data integrity. It targets administrators and workstation owners who need reliable capacity upgrades in compatible Dell platforms. The unregistered design fits standard UDIMM slots without requiring registered memory support. Every module uses major-brand DRAM from Samsung, SK Hynix or Micron.
Operating at 1.2V, the module runs at the standard DDR4 voltage to keep power consumption low and heat output minimal. Passive operation means no fans or moving parts, so the memory adds no audible noise to the system. The CL15 latency at 2666MHz provides efficient timing without raising voltage above the JEDEC baseline. Thermal load stays within normal limits for dense server or workstation configurations.
The UDIMM form factor installs directly into available DDR4 slots on supported Dell motherboards, freeing registered DIMM slots for other uses if the platform allows mixed populations. ECC capability protects against single-bit errors without requiring a registered memory controller. No additional cooling hardware or BIOS configuration beyond standard memory detection is needed. Buyers who need registered RDIMM or LRDIMM modules for higher-density configurations cannot use this unregistered kit.

Power off the system, open the chassis, align the notch on the module with the slot key, press firmly until the retention clips click, then verify in BIOS that the 16GB capacity and 2666 speed are detected before closing the case.
No scheduled maintenance is required; keep air vents clear so the module stays within its 1.20V operating envelope, and replace only if system diagnostics report correctable ECC errors rising above the platform threshold.
The CL15 latency at 2666 MT/s sets the throughput ceiling; sustained heavy traffic will saturate the PC4-21300 bandwidth before thermal throttling becomes a factor on an unbuffered 1.2V DIMM.
