the 480LowEnergyOK.rom is the most efficient

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

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?

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

Thank you!

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)

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%.

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.

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.

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" ).

Sure thing and you're very welcome.

Try latest drivers, heard that they aren't that bad when on Windows 10 (i cannot confirm this "yet" though..)

i get 29,7mhs eth and 327mhs sia, gpu-z showing 96w. -dcri 22. sapphire rx 480 nitro+ OC. with new drivers 16.9.1 you can adjust power limit in MSI AB... using win10..
claymore dualminer 6.4

Mm, i tried them, from the moment i started mining with my lowered rom that i'm using now the system froze, even after i raised the voltage a bit it still froze, only after raising it with almost 62mV it stayed stable.. so i quickly reverted back to 16.8.

Although, have to say, i tested on a win7 machine, i'm not sure, but it could be so that on win10 those drivers perform better. I'll definitely need to check that out!

Thx!

Yes, I use Sapphires. It could be brand related but I doubt it since its reference version - all brands should use the same supply from AMD.
