System-specific DDR3 SODIMM kit

This kit contains two 4 GB DDR3 SODIMM modules rated at 1600 MHz with a CAS latency of 11. They use a 204-pin unbuffered layout and operate at 1.5 V. The matched pair is designed for notebooks or small-form-factor systems that require DDR3 memory.

Standard voltage and unbuffered design

Running at the standard 1.5 V keeps power draw modest for typical office workloads and web browsing. The unbuffered construction adds no extra register delay, so the memory controller sees normal signal timing without additional heat from buffering chips.

Matched pair behaviour under load

Both modules share the same 11-11-11 timing, so the memory controller can keep dual-channel operation steady during extended sessions. If mixed with slower modules, the entire array will drop to the lowest common speed, which can limit sustained throughput.

Questions about this item

How do I install the 204-pin SODIMM modules and what step do people often miss?

Align the notch on each module with the slot key, press firmly until the side clips click, and verify the system reports the full 8 GB capacity in a 64-bit OS.

What maintenance or replacement will the 1.5 V DDR3 kit need over time?

No routine maintenance is required; if a module fails, the limited lifetime warranty covers repair or exchange against manufacturing defects.

What limit appears first during sustained workloads on the CL11 1600 MHz memory?

The CAS latency of 11 cycles at 1600 MHz sets the baseline response time that governs sustained throughput.
