SK hynix HMA84GR7AFR4N-VK 32GB DDR4 2666 ECC LRDIMM 2Rx4 Dell SNP2WMMMC/32G

Dell Precision T7920 compatible 32 GB DDR4 module

This 32 GB DDR4 LRDIMM is built for Dell Precision T7920 workstations that require registered ECC memory. It delivers 2666 MHz speed with CL19 latency at 1.2 V. The 2Rx4 organisation provides high density for multi-socket server boards. Buyers needing non-ECC or unbuffered DIMMs for consumer platforms should look elsewhere.

Capacity and headroom at 2666 MHz

A single 32 GB module adds substantial memory headroom for virtualisation, large datasets and memory-intensive rendering. The registered design and ECC protect data integrity under sustained loads. Systems limited to lower maximum module sizes or slower memory controllers cannot use the full capacity or speed.

DDR4 288-pin registered ECC limits

The DDR4 288-pin interface tops out at the JEDEC 2666 MHz rating used here; faster DDR4 speeds are not supported by this module. Registered signalling adds a clock cycle of latency but enables the large capacities needed in multi-processor servers. Workstations that require load-reduced DIMMs with ECC are the target platform; consumer boards without registered support will not post.
