Crucial CT16G4SFD832A 16GB DDR4 3200 laptop RAM

SKU CH-H3V4-9V2HS MPN CT16G4SFD832A

16 GB DDR4 SO-DIMM at 3200 MT/s, downclocking to 2933 or 2666 MT/s, CL22, 1.20 V

  • Capacity16GB
  • Type260-Pin DDR4 SO-DIMM
  • SpeedDDR4 3200 (PC4 25600)
  • CAS LatencyCL22
  • Timing22-22-22
  • Voltage1.20V

Capacity 16GB

  • 16 GB capacity adds headroom for multitasking
  • 3200 MT/s speed raises data throughput
  • Downclocks to 2933 or 2666 MT/s for broad compatibility
  • 20 V operation cuts power draw by up to 40 %
  • CL22 timing delivers low-latency response

Capacity and Form Factor

This 16 GB DDR4 SO‑DIMM uses a 260‑pin layout built for laptop upgrades. It suits owners of compatible notebooks who need a single module to reach 16 GB or to populate a second slot for dual‑channel operation. The unbuffered, non‑ECC design matches standard consumer platforms. Buyers who want more storage or registered ECC memory should look elsewhere.

Voltage and Efficiency

Operating at 1.20 V, the module follows the standard DDR4 voltage for mobile systems. Crucial states the 3200 MT/s design can reduce power consumption by up to 40 % compared with earlier DDR4 speeds, helping extend battery life during typical workloads. No active cooling or additional power phases are required.

Speed Behaviour Under Load

Rated at 3200 MT/s (PC4 25600) with CL22 22‑22‑22 timings, the module delivers its specified bandwidth during sustained transfers. If the platform only supports 2933 MT/s or 2666 MT/s, the RAM downclocks automatically to match. Faster burst access speeds improve sequential data throughput when the controller can sustain the higher rate.

Questions about this item

How do I install the 260-pin DDR4 SO-DIMM and what step is often missed?

Align the notch on the module with the slot key, insert at an angle, then press down firmly until both side clips click. The step often missed is not pushing far enough for the clips to lock.

Will the 16GB DDR4 3200 module need any maintenance or replacement later?

No routine maintenance is required. The module has no moving parts and operates at 1.20V. Replacement is only needed if a fault develops or capacity needs increase.

What limit appears first during sustained heavy workloads on this CL22 3200MT/s memory?

The CAS latency of 22 cycles at 3200MT/s sets the baseline response time. Under sustained load the memory controller may downclock to 2933MT/s or 2666MT/s if the platform cannot maintain the higher rate.
