That 470 4Gb where you have UberMix 3.1 is Samsung mem? I just really wonder if I can use it on 470 gfx. Everywhere is written it's for 480/580... I would like to try that on my Samsung 470, but dont want to brick it 
On my 480s the 3.1 is much agressive and I am getting mem errors fast. I am trying now 3.2b (didnt't found 3.2 final non beta) and it looks more stable but on higher frequences...
Yes, I have Asus Strix RX 470 with Uber-Mix 3.1. I'm testing it right now, after few hours stable at 2030Mhz it can go even above 2100MHz but almost no difference...On my 480s the 3.1 is much agressive and I am getting mem errors fast.

I have Asus Dual RX 480 8G with 3.1 and it has same hashes as the RX 470, but other Dual O8G didn't working more than few minutes with 3.1... and 3.2 had a lot lower hashes so I'm returning this card.
It doesn't matter what core the card has only it matters memory manufacture!
I bet if you could run 3.1 on 1800 or 1900Mhz it will be better than 3.2 on 2000-2100Mhz.
On 3.1 I was able to run at 2025 resulting 29.5 Mhs, on 3.1 at 2050-2100 resulting 30.7 Mhz. At the moment stable for just 2 hours with 0 mem errors -> now testing it through the night, in the morning lets see if it is a jackpot...
