to use that bios you have to change that AMD Driver right? What Crimson Version are you using?
You have two options.1. Manually disable signature check, there is alot of guides for that around.
2. Use one of the latest drivers that dont use signature check. Not sure about the performance with those drivers though.
I use the 16.8.2 driver

No need to push them that hard, you would generate a lot of heat, wear out the fans soon and maybe even burn your risers seeing how much power Polaris pulls through the PCIe slot.
Just copy the 1375 memory strap timings to all subsequent straps and voila, dual mining ETH/SIA 27.35/246 Mh/s at low low clocks of Core 1050/870 and Mem 1870/870 while drawing under 120W at the wall.
Do you run the 4Gb reference card ?Just copy the 1375 memory strap timings to all subsequent straps and voila, dual mining ETH/SIA 27.35/246 Mh/s at low low clocks of Core 1050/870 and Mem 1870/870 while drawing under 120W at the wall.
Yup, the RX 470 OC reference silver colored card with backplate.
I checked the rom i use in Polaris bios editor today.
All that is done with it is using the 1500 strap so i guess it is no point of redoing that.
What clocks do you run your memory at ?
I need to go atleast 1950Mhz to get over 27Mhs

Nice speed for that cards.
What settings did you applied? 1500Mhz memory strap? Which clocks & volts?

Real powerdraw not checked yet due to power meter tied up in my storage, probably around 150w per card. This rig is not optimized for low powerdraw just speed and stability.
Im curious about the whole system power draw

as per the builds and the cards used the total power used is probably somewhere between 850-900W i guess

Noob error... The difficulty on this website is far from being acurate. Check on Dwarfpool the "Frontier Diff". That is the actual difficulty.
PS : I'm not saying this to you, but to prevent some people to think they'll mine much more than what they'll get :/...
I wrote "at this diff/price"
I did not saw it, but in any case, even now I don't understand. You meant at this difficulty or at this price ?
For me it is pretty irrelevant though because i wont sell one single ETH in the coming six months atleast.
I just wanted people to get a clue about what the rig is producing.

Not a bad build considering the price of those cards. why are you OCing the memory so much?
To push the cards above 27Mhs, on stock clocks they perform around 25MhsI can push them even more to get around 28Mhs (close to 2000Mhz) but i dont want to push them too hard.

I added some more 470s when they where on sale here.
One of the cards perform a bit bad compared to all my other 470s of the same model. It is one of six cards that not perform like all the others, i guess it is just a bad sample.
I had really big problems getting my 480s to work flawless with the H81 boards but it seem like it is working better with the 470 cards somehow.
Setup:
OS: Windows 10 Professional
Custom Alu frame
Asrock H81 BTC Pro
Celeron G1820

HDMI Dummy Plug
64Gb ssd
Powered USB risers (one riser per powerline)
4 x Sapphire RX 470 4GB Reference (Custom bios, mem oc to 1960Mhz)
