Compatible Replacement for G.Skill Modules

This 4GB A-Tech module is built as a direct replacement for G.Skill part numbers F3-12800CL9Q-16GBZL and F3-12800CL9T2-24GBRL. It uses DDR3 technology in a 240-pin DIMM form factor and runs at 1600 MHz with a CAS latency of 11. The stick operates at the standard 1.5V and is unbuffered non-ECC.

Suitable for Standard Desktop Upgrades

The module fits desktop motherboards that accept DDR3 DIMMs and supports a tested frequency of 1600. It is not intended for systems that require ECC or registered memory, nor for laptops that use SO-DIMM form factors. Buyers should confirm their platform supports DDR3 before ordering.

CL11 CAS Latency at 1600 MHz

The memory runs at CL11 timing at the rated 1600 speed. This latency figure determines how quickly the module responds to read requests and must match the timing requirements of the target system for stable operation.

Questions about this item

How can I confirm the module is running at 1600 MHz with CL11 timing after installation?

Open Task Manager or CPU-Z and verify the memory tab shows 1600 MHz speed and CL11 latency at 1.5 V.

What comes in the package and do I need any extra parts to install this 240-pin DIMM?

The box contains one 4 GB DDR3 1600 CL11 unbuffered DIMM; no additional components are required for a standard desktop slot.

Should I choose the 4 GB stick or a larger kit to match the G.Skill F3-12800CL9Q-16GBZL specification?

This listing is a single 4 GB module; buy multiple units if your board needs 16 GB or 24 GB total capacity.
