8GB DDR3 1066MHz kit for Gigabyte 890 series

This 8GB kit contains two 4GB DDR3 SO-DIMM modules rated at 1066MHz with CL7 timings. It is built for Gigabyte GA-890FXA-UD5, GA-890FXA-UD7 and GA-890GPA-UD3H motherboards. The modules run at 1.5V and are unbuffered non-ECC.

Installation notes and common issues

The kit is a matched pair for dual-channel operation and must be installed in pairs. The motherboard has four sockets in two banks with a 16GB maximum. A 64-bit operating system is required to address more than 4GB. If 4GB is installed the system may only recognise 3.5GB.

Who this suits and who should look elsewhere

Builders upgrading or repairing the listed Gigabyte 890-series boards will find guaranteed compatibility. Users needing more than 16GB total capacity, ECC error correction or registered modules should look elsewhere. The 204-pin SO-DIMM form factor will not fit desktop DIMM slots.

Questions about this item

How do I verify the kit is running in dual-channel mode at 1066 MHz after installing it in my GA-890FXA-UD5?

Enter the BIOS and confirm the memory frequency reads 1066 MHz with both channels populated; the board supports up to 16 GB total across four sockets, and a 64-bit OS is required to see the full 8 GB.

What exactly ships in the box and is anything else needed for installation on a Gigabyte GA-890GPA-UD3H?

The package contains two 4 GB DDR3 204-pin SO-DIMM modules; no extra cables, brackets or software are required — just seat the sticks in the paired DIMM slots.

Should I choose this 8 GB (2×4 GB) CL7 kit or a faster 1333 MHz option for my GA-890FXA-UD7?

This kit runs at the board's native 1066 MHz (PC3-8500) with CL7 timing; the motherboard also accepts 1333 MHz (PC3-10600) modules, but they will down-clock to 1066 MHz unless the BIOS supports the higher speed.
