  • CL22 22-22-22-52 timings give low-latency response
  • 2 V operation keeps power draw and heat low
  • 260-pin SO-DIMM form factor fits standard laptop slots

Capacity and form factor

This PUSKILL module adds 8GB of DDR4 SO-DIMM memory to a laptop. The 260-pin layout fits standard notebook slots and the 1.2V operating voltage matches typical mobile platform requirements. It is a straightforward upgrade for users needing more system memory.

Thermals and power draw

Running at 1.2V keeps power consumption low, which helps preserve battery life and reduces heat inside the chassis. No heat spreader is fitted, so the module relies on the laptop's internal airflow for cooling. Under normal workloads the memory operates silently.

Latency and timing impact

The CL22 rating with 22-22-22-52 timings defines the access latency at the rated 3200MHz frequency. These figures determine how quickly the controller can read and write data. Builders who need tighter timings or ECC error correction should look for a different specification.

Questions about this item

How do I install the 260-Pin DDR4 SO-DIMM and which step do people often miss?

Power off the laptop, remove the battery if possible, open the memory compartment, align the notch on the 260-pin module with the slot key, insert at an angle, then press down firmly until both side clips click — the step most people miss is pushing until the clips lock audibly.

What maintenance or replacement will this 8GB DDR4 module need over time?

No scheduled maintenance is required; the module has no heat spreader and no moving parts, so replacement is only necessary if a fault develops or you later need more than 8GB of memory.

What limit appears first when the 3200MHz CL22 memory runs under sustained load?

The CAS latency of 22 cycles at 3200MHz sets the response-time floor, so sustained workloads hit latency-bound throughput before thermal or voltage limits become a factor.
