G.SKILL Ripjaws 8GB DDR3 SO-DIMM

This G.SKILL Ripjaws Series module provides 8GB of DDR3 laptop memory in a 204-pin SO-DIMM form factor. It runs at 1866MHz with CL11 11-11-11-32 timings and operates at 1.35V. The unbuffered, non-ECC design targets everyday computing and entertainment workloads on compatible notebooks.

Ideal for upgrading compatible DDR3 laptops

This module suits owners of laptops that accept 204-pin DDR3 SO-DIMMs at 1.35V and can run at 1866MHz. It is not for systems limited to 1.5V DDR3 only, nor for machines requiring registered or ECC memory. Buyers needing more than 8GB per slot or a different DDR generation should look elsewhere.

Rated 1866MHz DDR3 at 1.35V

The decisive specification is the 1866MHz speed at 1.35V with CL11 latency. Your laptop must support this voltage and frequency combination for the module to run at its rated performance. Each kit is 100% burn-in tested for stability.

Questions about this item

My laptop only has a 204-pin DDR3 SO-DIMM slot — will this module fit?

Yes, this module uses the 204-pin DDR3 SO-DIMM form factor, which matches that slot.

If I install this 1.35 V stick alongside an existing 1.5 V DDR3 module, what voltage will the system use?

The memory controller will run both modules at the higher 1.5 V, so the 1.35 V stick will operate above its rated voltage.

After installation, how can I confirm the module is running at DDR3 1866 with CL11 timings?

Check the memory tab in CPU-Z or the BIOS; it should show 1866 MHz and 11-11-11-32 timings.
