so here is my red devil 8GB ROM (sorry not 4GB) for the RX480
I'm calling it v2 because its basically the exact same settings as my V2 rom for the ref 480
You should get 31MH ETH and 340MH SC with this and around 170w at the wall with a gold PSU @ 230v
Temps are silly good as this card has a fantastic cooler and heat sink system and runs around 40% rpm at 71-73c in a hot room and is very quite
mine shows 57w GPU power but I don't believe that for a sec and expect there is a bug some where either in the card or GPUz and I declare this data as rubbish.
this card has been rock solid with these settings and I'm very pleased with it.
enjoy and flash at your own risk.
this is using the 1750 strap in the 2000 strap. I haven't had time to poke around with other straps but will look at that over the coming week as I expect there is a good option for 29MH low power like the ref card

ps: don't forget to reset after rebooting from the flashing and lower the mem to 950, you also have the option of more mem if you feel yours can take it mine are happy up to 2250 but show mem errors in HWINFO so dropped um down for the reliability and less power

Lowering the memory volt to 950, I try lower it to 900 but seems only have small effect for the wall watt (quite strange).
memory 950 draw 655 watt on 4 GPU rig
memory 900 draw 645 watt on 4 GPU rig
Good rom @boysie , waiting for your v3 coz i think the card got more potential.
@boysie What PSU do excactly use?
in the rig I use to build and test it I have some corsair 750, that rig only has 2 cards, a ref 480 and a 8G devil 480.

I need best quality usb riser hehe thx
It turned out to have some goo and dirt on some of the first pins in the slot. I scraped it out with a small metal tool and then everything went fine:)
So basically you are good with any type that you can by except the one with floppy connector.
I used wattman to drop the mem voltages down to 950 on all cards, and i'm noticing occasional hashrate fluctuations on some cards. Is this normal?
Its strange because for the first 2 minutes, all cards are running at ~30.8mh, then some of them drop as you can see in the screenshot below...
FYI: 5 x 480 Devil 8GB, Win10 Pro, 8GB RAM, 16.9.2 drivers, Claymore 7.0, ethi 16, dcri 27
It does not matter that it seems stable even at 875mV, but your pool side hashrate shows 10% less and you can see millions of memory errors in HWinfo.
So bump up VDDCI & VDDC and give a negative offset to VDDC in watttool.
download HWINFO and look in the sensor info.
Are running ok
The power comsumption is 112w , im using driver 16.9.2...
