Compatible DDR3 module for Gigabyte Z77 boards

This 4 GB DDR3 1600 CL11 DIMM is validated for the Gigabyte GA-Z77X-UD5H and GA-Z77X-UD5H-WB WIFI motherboards. It installs as a single 240-pin stick running at 1.5 V with 11-11-11 timing. The module uses major-brand chips in an unbuffered, non-ECC, dual-rank 2Rx8 layout.

Suits owners of these boards adding

Builders upgrading a GA-Z77X-UD5H or GA-Z77X-UD5H-WB WIFI system can use this stick to reach the board's 32 GB limit across four slots. Buyers who need ECC or registered memory, capacities above 4 GB per module, or a heat spreader should look at other options.

DDR3 1600 speed with CL11 latency

The memory operates at DDR3 1600 (PC3 12800) with a CAS latency of 11. This speed grade matches the highest frequency the compatible motherboards officially support, so the module will run at its rated specification without manual tuning.

Questions about this item

How can I confirm the 4GB DDR3 1600 module is running at 1600 MHz with CL11 timings after installation?

Enter the BIOS or use a tool such as CPU-Z; the memory tab should show 1600 MHz and 11-11-11 timings at 1.5V.

What does the package contain and is anything else required to reach the board's 32GB maximum?

The box includes one 4GB 240-pin DDR3 stick; to reach 32GB you must purchase three additional 4GB DDR3 modules to fill all four sockets.

Should I choose the 12800 1600 MHz version or a slower 10600 1333 MHz module for this Gigabyte GA-Z77X-UD5H board?

Both speeds are supported; the 12800 1600 MHz module will run at its rated 1600 MHz CL11, while a 10600 1333 MHz module would operate at the lower speed.
