I must admit to use Ethos with 7 gpus mining eth, 480 Nitro+ 8GB.

My 1200W PSU uses 1.27kW(!!) at the wall while mining with 28.86hs

What is the best bios to get the power down - i already tried some, but no success ...

Sapphire RX 480 Nitro+ 8GB 11260-07? Memory samsung?

has anyone used these roms with equihash(zcash)? I mine for most profitable and so my system goes back and forth between eth and equi. Was wondering what you got. I mine claymore's permutations.

i did a search in this thread and didn't find anything. summer time is approaching and in need to reduce my heat signature, but keep the same or better output.

For the 4x0 cards, it is better to mine ETH.

that doesn't answer the question asked.

Hey guys,

my card is SAPPHIRE NITRO+ RX 480 8GB OC, win10, Crimson 16.9.1
I have few questions please
I would like to flash the card with Jukebox v4.rom file. I can flush rom file with 256KB, but v4.rom file has 512KB.
I've copied the values from v4 to a previous silent rom file (256KB), but after some time - its crashing
any idea?
Thanks in advance!!!

VDDC Offset + Basic Custom timing
------------------
Here's a nice update for those who have Reference cards.
In the package included, i've put 4 roms with VDDC offset.

1. -50mV
2. -69mV
3. -81mV
4. -100mV

You can of course adjust these however you want, if you want to have an even tighter undervolt you can search the rom for this --> "8D 00 F8(-50)00" and replace the F8 part with EE(-112) for example.

These roms also have a custom timing included. It's a basic one but it will give you a very high increase for XMR.

Greetings and have fun!

Dear Eliovp

My card is Sapphire RX 480 Nitro 4gb (not nitro+)

Im can apply this rom ?

Can help me ?

Thanks
Almir

I don't think so, it "could" work but not necessarily and I wouldn't try it. it's easy enough to use polaris bios editor to mod your own rom there are guides or just ask for help

Hello,

I'm setting up my first rig and have (6) XFX RX480 8GB Black Edition cards. When I open my bios in Polaris Bios Editor, under timing I am not getting the same numbers as described in the examples. For example the first line is 26916491. Therefore I do not know which line to copy and past for the modification.

I tried applying one of the bios files supplied by the author, but when I did that Windows 10 would not recognize it. I had to boot into the command prompt and install the default bios to get it working again.

Can you help?

Thank you,

Brian

I modded my bios yesterday after this I cannot see temp readings or gpu frequency in gpu-z. anyone knows why?
asus dual 4gb
Thanks

Usually a driver signing issue. The original poster has the fix. Download the program called "Atikmdag Patcher", run it, patch, and restart. Sometimes I have to do it twice to get it to work.
Also, make sure you're using 16.x.x drivers, as the 17.x.x drivers won't work with modded bioses without some work.

Thanks, tried it but still no readings from gpu-z

I have this problem if the card is not plugged in directly. Once I plug the video card in to a monitor, then GPU z will detect it. Very annoying. Not sure what the fix is here.

Having some issues with a Power Color Red Dragon RX 480 8GB found here:
https://www.newegg.com/Product/Product.aspx?Item=N82E16814131704

I've tried the 30Mh, 32, and the low power ROMS. The first problem is that they were all 512kb, where my bios is only 256kb. My fix was to use polaris bios editor and copy the exact voltage, clock, and memory timings into a duplicate copy of my stock bios. None of these worked and windows just crashed.

I've tried the ROMs posted here:
http://1stminingrig.com/best-bios-rom-sapphire-nitro-rx-480-8gb-oc-mine-ethereum-30-mhs/

I've tried pretty much all of the ROMs created by boysie
https://forum.ethereum.org/profile/discussions/17803/boysie

There are also some ROMs posted at anorak.tech that I've tried that were specifically for this card:
https://anorak.tech/t/anoraks-vbios-collection-optimized-settings-for-performance-power-saving/13/3

None of these have worked. For now, I've flashed back to stock because I can at least get ~24mh/s.

Anything I'm missing? I'm very new to mining and coming off of a success high of getting my MSI RX 480 4GB from 22mh/s to 29mh/s.
EDIT: Adding more information. Pool mining using Claymore. Just testing with ethereum only mining. I've also tried multiple drivers. Pretty much every iteration from 16.7 to 16.11 and then the 17.x, even though those aren't supposed to be able to run on custom ROMs.

Here's my GPU-Z

Edit2: Copying my 1750 timings to my 2000 timings increased my MH to 28 on my stock rom using Polaris ROM editor. I'm hoping to get 30, if possible.

The roms here are for ref 480s.. the red dragon gpu is non-ref and may not be compatible with the ref bios's.

Is there a possibility to get a ROM for a 4GB version of the RX480?

Or is there one out there?

Guys, this rom works with Asus Strix RX 480 O 8GB? tryied to play with bios my self but do have interesting results under ethos - few cards at 28-29 and other at 18-19

all cards are same with samsung chips (Ellesmere). Maybe any1 can comment on that or share a rom wiht undervolt included (not sure how to undervolt rx480 under ethos)? Thx in advance for you idea/roms/solutions

My Custom Asus Strixx RX480 8GB Samsung.
http://wikisend.com/download/348864/Strix_Kuna_v9.1.rom

I'm running 1150/2060, of course You can go up 2100 and more. Set memory voltage to 950 with some tools. GPU voltage is automatic from P5 level.

did u try it on ethos as well? it seems that i get somekind errors with this rom... seems like it doesn't understand decreas of voltage of 950mV at 2000Mhz... or may be there is another issue?

Don't know for ethos, in windows use WattTool and there set 950 or less for memory voltage for each card, manually and later, if stable with a batch file.

windows not convenient, anyway flashed bios to have 29-30mh-s (running at 1310-1150/2150-2060, different cards different setups but it's stable for 24h) only option left is to try to decrease voltage under ethos but it seems that the option is Experimental at present version and doesn't do anything with RX480 Sad

or i'm doing something wrong?
