[Searching] ROM for Sapphire RX 470 Nitro+ 8GB

Hey guys,
I got a question.
I saw a lot of threads here about custom ROMs for RX 480 and 470. But I can't find any good, stable and tested ROM for the Sapphire RX 470 Nitro+ 8GB.
So my question is: which ROM do you use?
I use Ubuntu 16.04 with AMD GPU PRO drivers for my rigs and I want to stay with Ubuntu because of some reasons, so everything needs to be done in the ROM (undervolting and underclocking, I'm using claymore so I'm able to overclock without any problems).

Sad to say, after dualbooting for a while, I left Ubuntu 16.04 (which I would have preferred )for Windows10 as it consumed less power for roughly the same hashrate. If there's a way back sometime in the future, I'd be happier.
they seem to differ so much per card
one card for msi will hit mem 2k/900mV next wont break 1920 till 1010mV
one sapphire will scream just changing the straps and needs serious undervolting/optimizations next will need a slight boost to mem
because of what they can do i pretty much optimize every card by itself
The only 470 8GB ROM I've found is this from @uray

I haven't tested it and uray doesn't reply to my questions about this, so I don't think, this will work safe...
Probably we have to mod our ROMs by ourselves.
Just the strap 1750 -> 2000 and raising the ceiling for the RAM OC.
I'm now testing myself, when I got a stable ROM, I'll let you know!
I did undervolted a little today. 1000 mV core & 975 mV ram.
I don't want my rig to have anymore downtime than necessary. So i'm happy currently with the temps/power usage.
Plus releasing a ROM with undervolting done to it could make someone's life suck if it wasn't stable for their particular card given the ASIC quality.

Probably @boysie can give us an advice about this!
What results are you guys getting?
Best for me so far and 24hrs stable is:
Hashrate: 29.6 Mh/s
GPU only Power Draw (Gpu-z): 77.1 W
GPU Temp: 55°C
So M8thos have you attempted anything yourself? Any results?
Which adjustments have you made with Trixx and WattMan?
Is there a solution for Linux? We are only able to overclock, no downvolting or downclocking...
Currently I'm at 109 W and 122W
