There is a mod somewhere for sapphire RX470 4gb reference style. It works well. We can find it easily. (it's one megaupload)
I found a boysie mod for sapphire rx470 nitro 4gb too, but it didn't work for me because there are different clock version of the nitros.
Havent found the mod for mine.

After the ROM mod, trying to attempt any finetuning in AB 4.2 or 4.3 will crash the rig or become unstable.
For 480 case, messing with wattman is no picnic too and I could only get 33% reduction in -mV.
But using the ROM mod as it is, can already achieve 29MHs, low power - just under 1000w for 6xGPUs and considerably less heat.

Without using his low-power rom and using a different one, I have a 6 card rx480 rig doing > 29.1MH/s for each card pulling total 882w at the wall.
That is using Windows and the rom and applying -100 mV drop and it's rock solid (also Biostar motherboard).
That adds a lot of savings when you have multiple rigs!
the current SM Linux @ 6x480 @ 730watts with Heliox rom is running well and integrated with Claymore Ethman monitoring so I am happy with that.
I probably consider your approach too (Boysie's rom?) further power savings but my intention is to move away from Windows as much as possible.
No plans to dismantle this rig since its already ROIed -- but all future build will default to the 4GPU build.
Do you know any details of the mod? I have 470s (non MSI) so its hard to find a rom. So far I´ve only done the 1500er strap mod by myself but I´d like to save some power of course ;-)
honestly I havent seen 470 mods -- maybe you can start with the 480 mod thread here... the 480 thread is here https://bitcointalksearch.org/topic/m.15910357

What is SM Linux? Not using Boysie's, using Jukebox's bios. I would *love* to use Linux (it's what i'm most comfortable with) but the power saving from using Windows means at this point I don't have much choice unless I can somehow figure out how to do -100 mV drop for each GPU.
simplemining.net = SM Linux, tytantic's custom build image with ready to mine function, controlled from web master console. All the needed miners are available claymore, SA, optiminer, wolf etc.
nanos and 390s are very easy to do -100mV using AB but I give up on 480/RX cards -- thats why have to resort to mods.

most of the mods are "algo-optimised" - no good 4 profit-switcher.

What is the best, proven AMD Crimson driver version to use for mining ETC/XMR/ZEC? I see that 16.12.1 has been out a few weeks and 16.12.2 out just about a week, but are these recommended yet or would a more proven 16.11 be better for mining?
I use 16.11.3
really ? - I use 16.10.3 - works fine with RX-4x0 and R9 390 - even 4 gaming

Hope everyone is making money on XMR -- all my 33 rigs are on Dwarfpool XMR.
Yup, XMR all the way.
My long term goal is move to all Linux for stability and further power savings (6x480 takes 1000watts on Windows, but only 730watts on Linux)
Please explain how you managed to save power using Linux when you can not do -mV drop.
the RX480s were originally mining ETH during ETH hey days
All my 65 x RX480s are modded with "29MH480LowEnergyOK.rom" from Heliox/Eliovp
Used the same cards on ZEC and XMR, in addition to ETH with no issues and still achieve good wattage.
Settings on Linux is at "stock" no settings in simplemining or ethOS.
Under windows you can lower power consumption considerably with Trixx or Afterburner. I'm trying to gauge how you come to the conclusion that Linux uses less power than Windows.

Putting this same rig but under Linux (ethOS or SM), kill-o-watt show 730w for the same rig.
Both systems if mining ETH with Claymore 7.4 Windows or Linux achieve same 29MHs per GPU.
Without ROM mod, and just -100mV or -96mV with AB, with 6xGPUs, just under 1200watts in Windows.
Did not try Linux at that time because I havent tried ethOS or SM or meddling with AMD drivers in Ubuntu was just too complicated for me.
Until this guy called Heliox got his Nanos modded and shared with members....
Yes, all my Nanos are also modded with Heliox rom mods but I could manage only the -100mV version in which was already a saving in power but could have done more.
My only GPUs that are not modded and yet the best performer currently are the MSI 390s - solid like a rock, finetuned with AB4.2 -96mV and OCed slightly, delivering 30MHs per GPU in ETH. Solid in XMR and ZEC too.
The only downside are 390s are power hoggers and all 5 rigs (5xGPU x 5 rigs) uses 1600w EVGA-G2s which cost me a fortune.
Thats why I am never going back that alley and stick to the 4-GPU Biostar Z170 gold standard like Phils for future builds.... unless Panda Miner becomes a reality.

Win 10, 2 rigs with 10x RX 480 cards total
Claymore's XMR miner works 3-5 minutes and stopped
So have to stick to ETC
RX480, Win10 on XMR v9.6 -- use Crimson 16.11.3 or 4 to stabilise the rig.
Claymore need to improve the Polaris support for v9.6 miner

Hope everyone is making money on XMR -- all my 33 rigs are on Dwarfpool XMR.
Here is something to share, and hope it will save you time and effort...
Before this all the GPU rigs are on ZEC, ETH and XMR, spread across Nanos, 390s and 480s.
During the full swing to XMR, 3 rigs started to act up and I think its riser and driver related....
During ZEC, ETH mining -- the rigs are very solid and stable, good drivers and optimised speed, basically running well to my satisfaction.... but its suddenly not stable on XMR (working well before)
Instead of trying to meddle with Windows and Crimson drivers to make it work - I decided to use the magic sub stick which have saved me countless of midnight oil sessions before.
If you have not heard of simplemining.net before, suggest you visit his page.
My farm is all Windows due to learning curve on Linux and also poor AMD driver support in Ubuntu, etc.
My long term goal is move to all Linux for stability and further power savings (6x480 takes 1000watts on Windows, but only 730watts on Linux)
OK back to the usb solution, burn an image on a usb stick (prefer on usb3 for speed) from simplemining.net. Choose your image; RX (amdpro driver) or Non-RX (fglrx driver).
It will self update to latest version and start mining as per your miner app of choice in the master web console.
This fix got all 3 rigs to mine to Dwarf using Wolf XMR Linux miner which is very stable. You can also use Claymore but its using outdated v9.1 Linux build.
Anyways, this saved me a lot of time.... indicating that if it didnt work in the first place... and working now with Linux.... then the culprit can only be Windows... not the riser.
Good mining everyone.

before I forget my new evga board is acting up. so I kind of think only the biostar is good.

@vg54dett I think there is an asrock or something else what country are you in?
here is the asrock not sure it will work
http://www.newegg.com/Product/Product.aspx?Item=N82E16813157649
the biostar that works for sure
http://www.newegg.com/Product/Product.aspx?Item=N82E16813138421
the evga that was a real P.I.T.A. with 3 bios changes needed but it works with an m2 ssd and four cards
http://www.newegg.com/Product/Product.aspx?Item=9SIA1UH4R24324
note this evga has been a bit shaky .
So to be honest so far the biostar is the king.
I may order the asrock today not sure if I will
Thank you Phil,
Unfortunately, I can't find any of the 3 MB at a decent price in any EU country
Almost the same (or worse) as ordering in the US and paying shipping + customs...
