32GB DDR4 2666MHz desktop memory

This single 32GB module uses DDR4 technology at 2666MHz with CL19 latency. It is built as a non-ECC unbuffered DIMM for standard desktop systems. The 1.20V operating voltage follows the DDR4 specification.

32GB capacity and 2666MHz speed headroom

The 32GB capacity provides ample space for heavy multitasking, large datasets and memory-intensive applications. At 2666MHz the module delivers solid bandwidth for everyday workloads; latency-sensitive tasks may benefit from tighter timings or higher frequencies not offered here.

288-pin DIMM build and major-brand chips

The 288-pin DIMM fits standard desktop slots and uses major-brand chips tested for reliability. Unbuffered design keeps installation straightforward without registered-buffer overhead. The module targets compatibility with Dell part numbers AA846134, AA849194 and SNP983D4C/32G.

Questions about this item

Will this 32GB DDR4 2666MHz CL19 module run alongside my existing 2666MHz sticks?

Yes, this unbuffered non-ECC DIMM operates at the standard 1.2V and 2666MHz speed; it will run at the lowest common speed and latency of all installed modules.

How can I confirm the 32GB stick is recognised at the correct 2666MHz frequency after installation?

Open Task Manager’s Performance tab or check the BIOS memory information screen; both should show 32GB total capacity and a 2666MHz operating speed.

Does the package include only the single 288-pin DIMM or any extra brackets or cables?

The box contains one 32GB 288-pin DDR4 DIMM; no brackets, cables or additional hardware are supplied.
