I have the HEAVY ROM installed which is supposed to do 31-32MH and does.  However it will crash my system after just running for 1minute every time.  This is for both solo and Dual mining both with risers and direct on the MB.  The power draw at the wall is around 160-220 watts for the RX480 depending on solo or dual mining.  Don't just look at GPU-Z as its not reporting the PCI-E draw from the riser or MB.

The powersaving ROM at 29MH seems more stable.  Using Killawatt at the wall it's pull 185-190.  Deduct 55 watts for my system to get the RX480 card use.  Pretty impressive for 29MH using 130Watts with 16.7.3 driver.  When I upgrade to 16.8.2 I get the same performance but at 15-20 more watts usage.

Will try Boysie ROM next.  

Update - Same stability issues with Boysie's ROM which uses the most amount of wattage.   So far only the Powersaving 29MH ROM is stable for me.

Maybe your PCIE slot cannot support the 75W draw. You might use a powered PCIE riser to test the stability.


I think you may have missed the sentence where I mentioned I test both direct on the MB and via risers (powered).  I was chatting with other members on the Ethereum forum and it was working for them (MSI card) for over 2 days so it's something unique with my cards (XFX) perhaps since I'm using it on the same MB combo as everyone.  The Boysie ROM I was using was actually designed for XFX so I don't know what the deal is.  I even test it using a fresh new install OS, same issue.  Been running the LowPower ROM from this thread for 29MH at 130W since last night.  It works for Eth only with great power saving, it's not designed for Dual mining.  I need to get the Heavy version working as I want the highest hash rate for dual mining.

Nice stuff! Looking to get an RX480 myself so will see how things go

I shall wait until the OP gets the BIOS signed.

Otherwise it is too difficult for me as I have the miners in another place.

ok finally got the rom to work, had to do a full re-install of the drivers , copy the modded driver and then boot with option 7

not sure how to get option 7 to auto load on boot.

One issue I'm seeing

dual mining seems quite neutered compared to stock ? at 30 dcri I am seeing 24.5 eth and 360ish sc when before I was getting 23.5 eth and 420 sc

now if I mine eth only I was seeing high hash rates around 31mhs

Also the cards all now detect and 4GB I know others mentioned that as well, it does seem  that the core clocks are maxing around 980 which might be the reason for the low SIA or dual mining ?

Try this one Marvell, 29Mh otb, low power usage


Greetings
Thanks Eliovp , just tried this new bios and the cards defintlay seem to run cooler and more stable, howver I still get lower than stock when I use dcri over 20 for Sia coin.

I'm seeing around 22 mhs eth and 390 sia with my normal dcri 30.

With it lowered to 20 I get 26 mhs/eth and 200 SC

Maybe its my drivers ? I'm using the latest Driver 16.8.2

funny thing is when the miner initlally starts I see the expected rates : 26.5 mhs eth and 400 SC then it immediately drops down to 21 eth hmm
Your vram is probably overheating and throttling

Which version of the drivers are you using?

Here's what I'm seeing after flashing , unsure why no temperature are being reported - it's a stock powercolor rx 480



using the latest driver 16.8.2

not tried other drivers

Dual mining is only producing 23 & 350ish MH. However, solo is producing 31. Claymore is only reading the card as a 4gb. Am I doing something wrong to get such low dual mining?

that does not sound right you should be getting at least 27-28 eth and 400 sia, the whole point of dual mining is to keep close to max ETH hash rate and mine SIA as a bonus
tried dual and get 27 eth + 400 sia with temps rising, so i mine eth only...

What is the speed when you mine the ETH only? Is that the same 27 MH/s or the 31 MH/s mentioned by the OP?
eth only is 31

Does this ROM work for all Reference RX480 8GB cards?  I see some reference to Powercolor not working?  Also what is the latest tested Step by step process to get this working?  I see quite a bit of trial and error from the history but I'm not sure which 1 is the best practice to follow by after all the experienced gain from the testing.  Thanks.

29Mhs and low power - sweet music to my ears - will try this out tonight
