32GB DDR4 3200 desktop module

This 32GB DDR4 3200 CL22 DIMM uses a 288-pin layout and runs at the standard 1.2V. It is built with major-brand chips and carries a non-ECC unbuffered design for typical desktop workloads.

Installation and common issues

The module seats in a standard DDR4 DIMM slot and requires no extra cables or drivers. Most problems arise when the motherboard cannot train at the rated 3200 speed, so the system may fall back to a lower JEDEC frequency until the BIOS is updated or settings are adjusted.

Suitable for Dell SNP732YDC/32G replacements

This stick matches the Dell part numbers 732YD, AB120719 and AB133484, making it a direct swap for those systems. Buyers with laptops, servers needing ECC, or boards limited to lower DDR4 speeds should verify their platform specifications before ordering.

Questions about this item

How can I verify the module is running at 3200 MHz with CL22 after installation?

Open Task Manager or a hardware monitor such as CPU-Z and confirm the memory frequency reads 3200 MT/s and the CAS latency shows 22.

What ships in the box and is anything else required for installation?

The package contains one 32 GB DDR4 288-pin DIMM; no extra cables, brackets or software are needed — just a free DIMM slot on the motherboard.

Which capacity and speed version should I select for a Dell system that lists part numbers 732YD or AB133484?

Choose the 32 GB DDR4 3200 (PC4-25600) module; it is the direct equivalent for Dell part numbers 732YD, AB133484, AB120719 and SNP732YDC/32G.
