PLEASE USE EXTREME CAUTION WHEN MODDING YOUR BIOS THIS IS A USE AT OWN RISK I HAVE NO RESPONSIBILITY IN YOUR ACTIONS IF YOU RESULT IN BRICKING ONES GPU

So I have decided on putting this thread together as they are many threads been created and being lost in time and hard to find.
I am listing every one I can find here, from old cards, to new cards. I will be starting new first and working back in time to the older cards. I will be also providing details to what bios is for what card and version and brand etc. No doubt some of you will find this useful feel free to bookmark will save you having to bookmark a million different threads :P

This thread has tuns of modded bios well worth reading though each page will try to pull all bios from thread when I get chance but for now basic info.

AMD R9 390

Sapphire RX 390 Nitro Claimed Hash speed 39MH. If someone brave enough would like some testing done and provide status for this as that is insane hash.

Great Idea -- look forward to seeing some more Bios options.

I haven't messed with any of mine yet but I expect I will in the coming weeks.

This can be great Thread , but also there is a chance a lot of ppl, will mess up they cards ...
Same model number non reference cards can have a different BIOSes !!!

I have a couple of  Sapphire RX 480 Nitro+OC 8GB , they have 3 different  BIOSes as of today 10/2/16
13-2E3470U.X4L / 13-2E3470U.X51 / 113-2E3472U.053  ... Rom files are not interchangeable . You can flash them to another nitro , but then your hashrate will drop to lower 20's or under  , or your card going to hash around 4mh/s and you going to get a lot of "GPU ... hangs in OpenCL call " error .

MY xfx non refernce cards ( i have around 20 ) come with 3 different bioses  , Rom files are not interchangeable
113-p10xt-ibu1288-W80 , 113-p10xt-ibu1288-W81 , can not recall the 3rd one now :)

 ;) This Thread should start with a warning !!! Used at your own risk !!! ;)

That link you posted for nitro 8GB OC is for a Nitro 8GB OC with bios 113-2E.3470U.S52 , if you are going to flash that bios to another nitro with different bios number , you can brick your card ... im not saying you will, but there is a chance for that :(

You missed my Nano Thread ;)

Greetings!

So I did ill get it listed in next few. Also to he guys saying warning indeed I will be placing on thread too use at own risk and make sure have backup of orignal bios if modding tweaking etc as much risk comes with modding bios :)

Yeah my thoughts exactly on what I was reading up on it and different version can brick and done myself in past on older cards being a little out but had dual bios so could switch and back up recover and start out again. Can happen. No doubt I will try to list as many can here but also scan though and have minimal risk in or bricking chance.

anyone got any .ROM for old GPU like 7950, 7970, or R9 280?

good topic, great

I was also interested in this question, modding bios,  - 280x, 285

Very good idea, thank you.

I will try to get the modded 280x bios versions found I have come across a few but looking at them it didnt increase the MH that much on them but gave a better power reduction will see if can find them for you at some stage.


With regards to yours should have a uploaded bios shortly.

7950/7970 :)

Yes good idea for old gpus too.
I'm also interested with 280x ones.
thanks !

Nice thread subject !

 ::)

What's available for R9 290 & HD 6970 ?

No idea at the moment, I will be looking over the weekend tho to see what their is as I have a other stuff to up for 280 and 280x cards need to make sure its in date and still updated or maintained or posted on :)

Now added in Sapphire 390 mod claims to be 39MH+ Will be interesting to see but someone posted proof how true and stable this is would like some hardcore miners with the card to come along and test.

Good job on this thread 8) I'd like to add it to my website's tools section: http://monerobechmarks.byethost5.com/tools.php

That's also mine :)

But again, that's just a seriously heavy OC. I wouldn't recommend it :p

If anyone has a 270 and 270x modded bios that would be nice :)

Hey, i'm trying to mod 295x2 BIO for eth mining. Alas i botched it by loading BIOS from 2nd switch position and uploading to 1st. I only populated 1250 mem strap to higher levels but surprisingly in both switch positions card behaves exactly the same - memory freq doesn't affect hashrate at all. Also in both positions same card is displayed as master (the one with lower ASIC).

So i started to wonder if this card has really dual BIOS or i did mistake editing mem straps timings, or maybe previous user already did it?

I'm also surprised that gpu clock has almost 1:1 effect on hashrate, like this card was GPU bottlenecked. My best settings are so far GPU clock 1050Mhz @ ~1,075 VDDC and 72 degrees. It gives me 60 mhash overall. Can't go higher because of temps or lack of stability when further reducing voltage. I've read people achieved 66-70+ mhash. Maybe my cooling lost efficiency, or they increased temp target?

I like the idea of this thread but instead of just linking the threads, maybe post a link to each available bios with a screenshot of settings for that particular bios. Or the polaris bios editor screenshot to make the bios yourself.

Also have the authors of the bios next to each with a BTC donation address.

Just my 0.2

You got any for that card that works well and a good balance something in the mids am at 32MH on mine without overclocking much and undrclocking card by -12mv and works well.

I saw that there is a bios for rx 480 ref 8gb, only 4 gb, or I do not find it I? :'(

They are lots out their but many wont share them as they made them their self but am looking around for ones that people provided and made public. I am considering doing some myself and learning the filed to mod roms but looks like a lot of work to get them working rock solid and lot of time that I currently do not hold. Soon as I find different version they will be posted here as I collect information.

Hi!,
    I was looking through the forum for a mod for the Sapphire RX480 Nitro+ 4GB and found this from Eliovp
https://bitcointalk.org/index.php?topic=1584617.msg16814666#msg16814666
He posted an open download link so it would be a nice addition to this thread.
I did not test it yet but i ordered 2 sapphires RX480 Nitro+ 4GB that should arrive in a little less than a week, after i figure out how to get the mod to work i could post my findings here.
If anyone else is ready to test this and post results, that would be great.
Until next time~
