32GB DDR4 2933 SO-DIMM

This 32GB DDR4 2933 CL21 module is built for laptop and all-in-one owners who need a single high-capacity stick. It runs at 1.20V and uses the standard 260-pin DDR4 SO-DIMM form factor. The unbuffered non-ECC design matches the Hynix HMAA4GS6MJR8N-WM specification for direct replacement.

Fits a single SO-DIMM slot

Installation requires one free 260-pin SO-DIMM socket and a platform that accepts DDR4 2933 PC4-23400 memory at 1.20V. The module frees the second slot for a future upgrade and adds 32GB without populating both channels. No heat spreader is fitted so it clears tight chassis spaces.

Sustained workload stability

All modules pass quality assurance testing to verify reliable operation under continuous load rather than short bursts. The CL21 latency and standard voltage deliver steady throughput for multitasking and heavier workloads. Buyers who need ECC error correction or registered buffering should choose a different module.

Questions about this item

Will the CL21 latency limit throughput during sustained workloads?

CL21 is the rated CAS latency for this DDR4 2933 module; it sets the timing floor for every access cycle.

Does the module run hot or draw extra power during all-day operation?

It operates at the standard 1.20 V DDR4 voltage with no heat spreader, so thermals and power stay at baseline DDR4 levels.

What must the laptop already have for this 260-pin SO-DIMM to work?

A free DDR4 SO-DIMM slot that accepts 260-pin modules and supports 2933 MHz non-ECC unbuffered memory.
