[UPDATE] RX480 (Ref) 31+Mh, Custom Rom - VDDC OFFSET + Custom timing

[AzzAz]

Thanks again Heliox
now i am using your low power rom, i replaced main parameters in my original roms with your settings and left other (like subvendor ID and .. ) unchanged also i left memory at 8 gb.
now my cards (3 asus and 3 gigabyte) hash around 30.5,  work around 70-80 C at 65% fan speed , gpuz shows between 90-100 watt.
other parts
asrock h81 btc
16 gb ram
g 3220
1200 oc power

whole system drawn out 1150 at wall , i think i have should missed something because other report better power consumption.
also wattman doesn't accept changes for power limit and or core freq.

I appropriate any help

You are pretty ok, gpu-z is unreliable. i.e. Testing my 470 OC STRIX: ATM: gpu-z: 85W. Killawatt: 150W ( 180W-system 30W )
To add: Almost same as my 480 OC STRIX... with 25% more hash. Only 470 produces significantly less heat.
Yet to measure 480 reff with Elio's 29lowEn. rom ( working as a charm on 5 cards ) - everything 16.9.1 Win 10 ( also "as a charm" ).

I have found these:
480LowEnergyOK.rom
RX480-30MhOTBLowEnergy.rom
RX480-31.8HighPower.rom
RX480Mod.rom
Am i using the correct one for low power 480LowEnergyOK.rom? Can you tell me hashrate & gpu-z watt of the other?
From my measurements 480LowEnergyOK.rom should be called 480_29mhash_85watt.rom
I have not yet tested for hours so is this the correct rom for low power?

RX480-30MhOTBLowEnergy.rom gives me 30.6Mhs rock solid 24/7 on my ten 480 8Gb cards.

[Cryptozillah]

Just got a couple of "cheap" 470 4Gb reference cards up.
Kicking myself a bit for buying 480s actually.
28+Mhs on custom roms.

Cards used: Sapphire Radeon RX 470 4Gb Reference
http://www.sapphiretech.com/productdetial.asp?pid=0582294D-5A90-4EF0-B5E1-5EDC1C3ACBE1&lang=eng

Rom used: http://www.megafileupload.com/k2gu/470_4gb_sapphire_modded_bios.rom

Mem overclocked to 2000Mhz = ~28+Mhs

Sorry for offtopic but this info can be handy fot the ones that cant descide if they want to buy 470s or 480s.

24+ hours running steady at 29.1 gpu 0 and 28.9 gpu 1. XFX 480 reference. 75 C on each cards with fans at about 60%.

[akaloith]

using 480LowEnergyOK.rom with 16.9.1 and CDM 7.0 mining at ethpool.org, running approx 2 days now - very stable holding 29MHs per GPU.

This 16.9.1 seems to be the life saver....

Your cards (I think you have Sapphires) held it well even with previous drivers. I'm trying to understand what causes the drop in hashrate of my XFX.

This is why I asked akaloith about stability of hashing

yes its steady for 10 hours. i tweaked the fan and the temperatures and now get a 72 C at 2500rpm. I have gigabyte reference but i believe all are same. maybe bad asic quality? check it on gpu-z. mine is 75% (not so good)

Obviously you have all these roms - could you please upload them somewhere and share the links with us?

Thank you!

all the rom links are in authors Eliovp last posts

of course i dont have the right to reupload others work

Hey guys.

I've also been playing around a bit to find an optimal setting Hash/watt.

This is where i am so far.

Will probably get it better though :p

Eliovp what about this? not stable? any rom for the above?

That is what GPU-z says, but not real power...

of course real power is more. just something to compare. i saw my plug on the wall and could also see the raises in watt. from 320 it even reached 400. its better than nothing. dont like it? dont see it
my power meter on the wall confirmed that the lowest power usage come from 480LowEnergyOK.rom while maintaining 29mhash

Appreciate it

[sigwo]

Are there any ROMs for the Sapphire Nitro+ 4GB RX 480? I tried the 480LowEnergyOK.rom and I get the error 'UVD not responding, trying to reset the VCPU!!!'

Luckily there is a VBIOS switch I can flip

EDIT: Also, any 4GB ROMs for the MSI RX 480?

[ps_jb]

Could you please specify in topic that it is for 8Gb card? Otherwise many people mistakenly try to flash 4G cards

GPUz reports the power used by the graphics chip itself.  A watt meter is able to report the power (delta) of the whole card: graphics chip, memory chips, VRMs, etc.

Each memory chip probably consumes about 5W of power or so.  These cards probably have 8 or 16 chips on them.

nice result, currently im using 480LowEnergyOK.rom, in dualmining i get 28mhs+300mhs with 102watt
i think it's still profitable than use only ethereum mining

Hello,

i have an ASUS RX 480 (GPU Device Id: 0x1002 0x67DF 113-D0090101-100 67DFHB.15.50.0.0.AS01 (C) 1988-2010) Card with the
BIOS Version: 2016-06-14 04:43:00   015.050.000.000.000000   PCI-E

When i try the modified BIOS, i get the Error "invalid Sub-ID".

Then i tried the modification (Memory Clock, etc.)  with the Polaris Editor manuell, but then the System don't accept the Card.
In Windows 10 the Card will be displayed with a problem, in my Linux the card won't detected.
Has anybody an idea?

Thank you very much.

Best regards

Zimbo
