Compatible DDR3 upgrade for Gigabyte Z77 boards

This 16 GB kit contains two 8 GB unbuffered DIMMs built for the Gigabyte GA-Z77N-WIFI, GA-Z77P-D3 and GA-Z77X-D3H motherboards. Each module runs at 1600 MHz with CL11 11-11-11 timing at 1.5 V. The kit targets owners of those three boards who want to add or replace memory without compatibility guesswork.

Sustained-load behaviour at DDR3 1600 CL11

The modules operate at standard JEDEC voltage and timings, so they maintain their rated 1600 MHz speed during extended workloads without requiring manual voltage increases. Unbuffered 2Rx8 organisation and the absence of a heat spreader mean thermal headroom depends on case airflow rather than on-board cooling. Systems filled to the board’s 32 GB maximum will see the same latency and voltage characteristics per module.

Straightforward two-stick installation

Installation follows normal 240-pin DIMM procedure: align the notch, press until the retention clips click, and power on. The board accepts 1066, 1333 or 1600 MHz modules, so the kit will down-clock automatically if the BIOS defaults to a lower speed. Builders who need ECC, registered DIMMs or capacities beyond 32 GB total cannot use this product. No heat spreader is included, so tight clearances around large CPU coolers are not a concern.

Questions about this item

Does the 1.5 V DDR3 1600 kit run hot or need extra cooling when the system is on all day?

The modules operate at standard 1.5 V without a heat spreader, so they stay within normal DDR3 thermal limits during continuous use.

My Gigabyte Z77 board has four slots — do I need to populate all four for this 2 x 8 GB kit to work?

No, the 16 GB kit is a matched pair that works in two slots; the board supports up to 32 GB across four sockets.

Will these CL11 1600 MHz sticks downclock automatically if I keep my older 1333 MHz modules installed?

Yes, the motherboard supports 1066, 1333 and 1600 MHz speeds, so mixed modules will run at the lowest common frequency.
