16GB DDR4 2133MHz module

This 16GB DDR4 2133MHz module is a single 288-pin DIMM rated at CL15 and 1.20V. It is built for desktop systems that accept unbuffered non-ECC memory. The stick uses major-brand chips and is tested at 2133 MT/s to deliver dependable capacity for everyday workloads.

HP part-number cross-reference

The module replaces HP part numbers 797347-591, 798035-001, 834933-001, 840819-001, T0E52AA, T0E52AT, Y3X96AA and Y3X96AT. Matching these references lets you confirm compatibility before purchase without guessing supported configurations.

288-pin unbuffered DIMM build

The standard 288-pin DDR4 DIMM fits regular desktop slots and operates at the JEDEC 1.20V level. Unbuffered construction keeps the signal path direct, while the single-rank 2Rx8 organisation works with typical consumer motherboards that support 16GB per slot.

Questions about this item

Will the 1.20V DDR4 module need any voltage adjustment or replacement as it ages?

The module runs at the standard 1.20V DDR4 voltage and is unbuffered non-ECC; no voltage adjustment is required and the chips are tested for long-term reliability.

What limit appears first when the 16GB stick runs at 2133MHz CL15 for hours?

The CAS latency of CL15 at 2133MHz sets the timing boundary; sustained throughput is capped by that rated speed and latency.

How much heat or noise does the 288-pin DIMM produce during all-day use?

As a passive 1.20V DDR4 DIMM with no fan or moving parts, it generates minimal heat and zero audible noise under continuous load.
