Computer Memory Solutions CM1024642400SO 8GB DDR4 2400MHz SODIMM for Lenovo IdeaPad 320 series memory upgrade

SKU CH-6CAK-BGPS9

8GB DDR4 2400MHz SODIMM module with CL17 timing and 1.2V operation, built for Lenovo IdeaPad 320 series laptops

  • Capacity8GB
  • Type260-Pin DDR4 SO-DIMM
  • SpeedDDR4 2400 (PC4 19200)
  • CAS LatencyCL17
  • Timing17-17-17
  • Voltage1.20V
  • Guaranteed fit for Lenovo IdeaPad 320 series laptops
  • 8 GB DDR4 module expands multitasking headroom
  • 2400 MHz speed with CL17 timing for responsive performance
  • Low 1.20 V operation reduces power draw
  • Single 260-pin SODIMM installs in the sole memory slot

System-Specific SODIMM Upgrade

This 8 GB DDR4 module is built for the Lenovo IdeaPad 320 series, including the 320R-14ISK, 320R-14IKB, 320-14ISK, 320-15IKB and 320S-14IKB models. It targets owners who need a single 260-pin stick to expand capacity without replacing existing memory. Builders working on other platforms or requiring ECC support should look elsewhere.

Sustained Load Behaviour

The stick runs at 2400 MHz with CL17 timings at 1.20 V, unbuffered and non-ECC. Under continuous workloads the memory operates at the speed of the slowest installed module or the processor limit, so mixing with slower sticks will reduce overall throughput. No heat spreader is fitted, so airflow in the chassis manages thermals.

Deciding Specification

Capacity is 8 GB in a 2Rx8 configuration, and the laptop provides one SODIMM socket with a maximum supported capacity of 16 GB, 20 GB or 24 GB depending on the exact model. A 64-bit operating system is required to address more than 4 GB.

Questions about this item

Does the 1.20V DDR4 module run hotter or draw more power than lower-voltage alternatives during all-day use?

The module operates at the standard 1.20V for DDR4 SO-DIMMs, so power draw and heat are typical for this class and should not stress the IdeaPad 320 cooling.

My Lenovo IdeaPad 320-15IKB has one SODIMM slot — will this single 8GB stick work without a matched pair?

Yes, the laptop has one socket and supports up to 24GB; a single 8GB stick installs directly and runs at 2400MHz CL17.

If I keep the original 4GB stick and add this 8GB module, will the system still run at 2400MHz?

All installed memory runs at the speed of the slowest module, so mixing with a slower original stick will drop the 2400MHz module to that lower speed.
