The bios is set to optimized defaults.
I could try testing the sticks using memtest86+ if you think it would help?
The fact that all 4 sticks will work one at a time leads me to think that the memory is not outright defective.
Will it boot from one stick, REGARDLESS of the slot you use? Or is it possible you have at least one dead slot?
Here is the support site for your motherboard: GIGABYTE - Motherboard - Socket 1155 - GA-Z77X-D3H (rev. 1.0)
I just looked at the manual. You should download it if you haven't.
Look at page 16.
The manual says that using 2 sticks, you should install one stick in the slot farthest away from the CPU and the other stick two slots closer to the CPU (second closest slot to the CPU).
I assume you are aware of the notches in the sticks and that they are seating and locking properly?
Have you confirmed that your memory is on the supported memory list? http://download.gigabyte.us/FileList...a-z77x-d3h.pdf
Memory that is NOT on that list should still work if within basic specifications.
If you have proper memory, properly installed, I would contact Gigabyte support to see what they have to say.
