8GB DDR3 SO-DIMM kit for Gigabyte boards

This 8GB kit contains two 4GB DDR3 SO-DIMM modules rated at 1066MHz with CL7 timings. It is designed for notebooks or small-form-factor systems using the Gigabyte GA-870A-UD3, GA-880G-UD3H or GA-880GA-UD3H motherboards. The modules operate at 1.5V and use unbuffered, non-ECC chips.

Sustained load behaviour with CL7 timing

The CL7 7-7-7 timing provides low latency for consistent responsiveness during extended workloads. Running at the standard 1.5V DDR3 voltage helps maintain stable operation without excess heat generation. The unbuffered design ensures direct communication with the memory controller for predictable throughput.

DDR3 1066MHz interface practical limits

The DDR3 1066 (PC3 8500) interface caps bandwidth at this speed grade, so faster modules will downclock to match. The supported motherboards accept up to 16GB total across four sockets, limiting this two-module kit to half the maximum capacity. Systems requiring 1333MHz (PC3 10600) will still function but at the lower 1066MHz rate.

Questions about this item

How much power does the 1.5V DDR3 kit draw when the system runs all day?

Each module operates at 1.5V; total draw depends on the motherboard's memory controller and load, but the rated voltage is 1.5V for both sticks.

What motherboard slot does the 204-pin SO-DIMM require?

The kit uses 204-pin DDR3 SO-DIMM modules, so the board must provide DDR3 SO-DIMM sockets — the listed Gigabyte models use 240-pin DIMM slots, so verify your exact model before ordering.

Will the 1066MHz CL7 modules work alongside existing 1333MHz DDR3 sticks?

The motherboard will run all installed memory at the lowest common speed; mixing 1066MHz and 1333MHz DDR3 is possible but the faster modules will downclock to 1066MHz.
