A-Tech 32GB DDR3L 1066 ECC RDIMM 4Rx4 for Dell A5272862 A5283563 SNPM77TYC/32G Server Memory

32GB DDR3L ECC RDIMM for Dell Servers

This 32GB registered ECC module runs at DDR3L 1066 (PC3L-8500) with CL7 latency and 1.35V operation. It uses a 4Rx4 organisation on a 240-pin DIMM and is built with major-brand chips. The part replaces Dell part numbers A5272862, A5283563 and SNPM77TYC/32G in compatible server and workstation platforms. Buyers who need non-ECC or unbuffered memory for consumer boards cannot use this module.

Sustained load behaviour with registered ECC

Registered buffering reduces electrical load on the memory controller, allowing stable operation when all ranks are populated across multiple channels. ECC corrects single-bit errors on the fly, preventing data corruption during long compute jobs or virtualisation workloads. The 4Rx4 density delivers high capacity per slot, though the increased rank count can limit maximum supported DIMMs per channel on some platforms. Systems that do not support registered ECC will not POST with this module installed.

Thermals noise and power at 1.35V

DDR3L 1.35V operation lowers power draw and heat output compared with standard 1.5V DDR3, easing cooling requirements in dense server chassis. The module has no onboard fan; thermal performance depends on system airflow across the DIMM slots. Under typical server workloads the memory runs within JEDEC thermal limits without additional cooling. Acoustic impact is negligible because the component is passive.
