Capacity & form factor

This is a single 32GB DDR4 SO-DIMM built on a 260-pin printed circuit board and rated for 3200 MHz operation at PC4-25600 bandwidth. It runs at the standard 1.2V and uses unbuffered, non-ECC architecture with CL22 latency timings.

Upgrade fit

The module suits owners of compatible laptops, notebooks or all-in-one systems that accept a 32GB DDR4 SO-DIMM and need a direct replacement for the Crucial CT32G4SFD832A part number. Buyers whose devices are limited to lower maximum capacities per slot or that require registered or ECC memory should look at something else.

Deciding spec

The 260-pin DDR4 SO-DIMM form factor is the single specification that determines whether this module will physically install and function in a given machine; verify the slot type and maximum supported capacity before purchase.

Questions about this item

Does the 32GB DDR4 3200 CL22 module throttle under sustained heavy workloads?

This DDR4 3200 CL22 SODIMM runs at the standard 1.20V JEDEC voltage with unbuffered, non-ECC operation, so it does not generate the extra heat that causes throttling on overclocked or over-voltage kits.

How much heat and fan noise will the 1.20V 32GB stick add during all-day use?

At 1.20V the module stays within normal DDR4 thermal limits, adding negligible heat and requiring no extra fan speed in a typical laptop chassis.

My laptop only has one free 260-pin DDR4 slot — can I install this single 32GB module without a matched pair?

Yes, the 1x32GB configuration works as a single module in any compatible 260-pin DDR4 SO-DIMM slot; no matching pair is required.
