I found my 6 GTX 1070's at 60% power profile (120 core, 720 memory) consumes 760W which on the Silverstone 1000W PSU (1100W peak) will do the same (i.e. restart) occasionally. I only run two riser cards off each SATA power rails and two off molex rail as well. Benefits of gold or platinum rated PSU certainly matters, so when I can afford it I'll like upgrade my PSU to prevent the issue of my mining rig restarting.

Says it quite clearly here: https://www.gigabyte.com/MicroSite/462/mining.html

Don't worry I had the same issue but after carefully reading the important steps and settings here: https://www.gigabyte.com/MicroSite/462/mining.html I managed to get it to work. Think the setting that caused issue was Compatibility Support Module (CSM) option. It says to have 'Disabled' but from memory I had to have it 'Enabled' before my 60GB SATAII  SSD would boot Windows.

The other important steps to follow, some already suggested were:
1. Update BIOS - latest version 25a here: https://www.gigabyte.com/Motherboard/GA-H110-D3A-rev-10#support-dl
2. Change “Max Link Speed” setting from “Auto” to “Gen2” (M.I.T / Miscellaneous Settings / Max Link Speed)
3. Enable Mining Mode (Peripherals)
4. Change "Initial Display Output" setting from "PCIe Slot1" to "IGFX" (Peripherals) - initially I wasn't using on board graphics but seems best option to free up resources.
5. Change “Above 4G Decoding” setting from “Disabled" to “Enabled” if needed (Peripherals) - I have GTX 1070's with 8GB vram soof course I enabled this feature.
6. Windows Update turned off is recommended - I went one step further and ran Spybot Anti-Beacon link: https://www.safer-networking.org/2016/anti-beacon-1-6-available/
7. Go to Control Panel / System and Security / Power Options and select "Choose what the power buttons do". Click "Change settings that are currently unavailable" and disable the "turn on fast startup (recommended)" function.

Also wanted to mention the ability to run a 7th riser on the M.2 slot isn't supported on this model for those considering it. Chart clearly says 6*PCI-E only. If you're considering purchasing this motherboard I can't fault it like OP, although I think like anything it takes patience and doing some research before jumping to conclusions. Here's an interesting review link: http://1stminingrig.com/gigabyte-ga-h110-d3a-review-the-new-best-motherboard-for-mining/ Note down the bottom there are also comments about people overcoming similar issues.

Sorry to sound like newbie, but where is the awesome miner thread? Can you post a link please?

Thanks for the replies. Well I'm currently mining on MPH where I auto-exchange to either BTC or LTC since I'm GPU mining, and HODL ETH and ZEC when they're the most profitable coins to mine (according to MPH Coin Mining Profit Switching). I understand what your saying @fanatic26, when I first started out I was mining ZEC only on Suprnova.cc and it seemed more consistent between transactions, i.e. no time waiting for auto-exchange to go through. Although I do like being able to be paid in coins I can't necessarily mine with my current rigs (algo's like SHA-256 / scrypt etc).

So I found a post here: https://www.reddit.com/r/gpumining/comments/7ixtrv/awesome_miner_profit_switching_seems_arbitrary/ that seems to validate Goose-Tech's reasoning with slightly higher values for both Switching interval (60) and threshold (20%) recommended. The comment is also made: "I don't care about penny gains. You also have to watch difficulty changes. If everyone jumps to a new coin. The coin you are mining might get easier." Will try using these new values and report my findings. 

First time posting, just curious to know what (%) amount is the "sweet spot" for Profit switching threshold in Awesome Miner general settings?

Thanks to watching Goose-Tech https://www.youtube.com/channel/UCv7Rsd8A6cW_kInX2fkDevA videos on different methods of mining with Awesome Miner and Mining Pool Hub, I've seen higher profits already configuring my rigs to switch algorithms.

However in his video here:
 https://www.youtube.com/watch?v=jYXuxvj4xdI at around 31 mins he explains that he sets the Switching interval to 3 minutes, and a threshold amount of 15%. He goes on to say he does this because he found that the lower the threshold was, or if no threshold was set at all, it would constantly switch resulting in spending more time switching between different mining software than actually doing any kind of mining.

Has anyone else experimented with this setting, or have any recommendations? Thanks in advance.
