SRBPolaris V3.5 - BIOS editor for AMD RX4XX and RX5XX cards

[bardacuda]

I just tried them and the signature check fix doesn't seem to work anymore.

I just tried them and the signature check fix doesn't seem to work anymore.

It works, cause all it has to do is remove the little yellow triangles from the system/devices part, and not to allow you control fans/voltage/etc..

 tested with new amd drivers with DAG correction. Works on all my rigs.

Yeah apparently it just doesn't work on Win7

Hello,

I have 3 RX480s that I've been mining (ETH/SC) w/Claymore in my gaming rig, to give me time to learn the ropes before building dedicated mining rigs. They're all still at defaults, but I'd like to:

• lower their power use, and
• see if I can bump their hash rates up.

The cards that I'd like to explore modding the BIOS on are:

• XFX RX 480 RS 8GB 1288M XXX HS BP (RX-480P836BM/RX-480P8L),
• PowerColor RED DRAGON RX 480 8GB GDDR5 (AXRX 480 8GBD5-3DHD), and
• Gigabyte RX 480 WINDFORCE 8GB (GV-RX480WF2-8GD)

I've read through this entire thread. You're welcome to tell me to RTFM again, but I'm not entirely comfortable that I wouldn't brick the cards. I've looked at the default BIOS roms in SRBPolaris, and they're all recognized. Is there a source on these models on what settings ppl have found ideal? Do I just need to experiment, and hopefully not destabilize the rig repeatedly?

Any tips or resources you can point me toward would be greatly appreciated!

P.S. In case other device, etc. stats matter:

• MSI GTX 1070 X Gaming as my main GPU (gaming),
• SAPPHIRE Vapor-X HD 7950 3GB 384-Bit GDDR5 mining (b/c I haven't gotten rid of it yet). 
• MSI Z87-GD65 Gaming motherboard,
• i7-4770K (3.5 GHz)
• 32 GB (G.Skill (4 x 8GB) DDR3 PC3-19200 2400MHz TridentX)
• Windows 10 Pro
• SK hynix 500GB SSD
• Barracuda 3TB x6 (RAID5)

To mine ETH you need mostly memory speed. So you have to copy lower memory straps to the higher ones, increase memory speed and lower core speed a bit to reduce power consumption. all this can be made with SBPolaris.
About the 1070, you can mine ETH with it. Check memory brand to see how much you can OC.
I think most people use the 7950 to mine ZEC.
You don't need all that RAM.
Also, be aware of your PSU, because there's a lot of power hungry GPUs there.

Forgot to include my PSU on that list. Sorry.

Hi All,

I have 12 * Saphire RX570 Nitro+ 8GB OC cards split across 2 rigs running Linux and have copied the memory straps, amended the default core and gpu speeds and so the first part is fine as the cards are giving me an average of 24.8Mhs using the config 1281/2150.

However, when it comes to undervolting, I've tried using SRBPolaris to do this by setting the voltage at 850 however after saving the rom and flashing, after a reboot of windows the card is still drawing 147w.  If I then manually undervolt in Trixx by -150 then the draw comes down to 114w which is much more acceptable.

As my rigs are running Linux I need to undervolt via bios mods hence the plea for help as I'm obviously doing something wrong, I just don't know what.

I've read lots of references to having to HEX edit the bios to do this, if this is the only option, can someone point me to an article that will educate me in how to do this (safely) as I thought that either PBE or SRBPolaris were writing the necessary changes to the .rom file and therefore not clear on what the HEX editing will do that these utils are not?

Apologies for the noob questions, this is my first setup and am very eager to learn!

Cheers

the values in my core voltage are like these "65288". i edited it to a value of 900v but its still pull a lot of Watts

Do you, by any chance, know how to read a 1070 bios? I'm interested in finding where the memory straps are located in hex.

Do you, by any chance, know how to read a 1070 bios? I'm interested in finding where the memory straps are located in hex.

I think I know how to read it (at least partially).
Why do you want it?
Custom 10xx bioses can not be flashed without HW programmer anyway.

[doktor83]

but then again, are those edited bioses working after flashing with a programmator?
I mean, some checksum in the bios itself has to be fixed too, no ?

[cvsea]

I may have found a way to sign the rom.
But I can't find the location of the straps + there is the problem of fixing the checksum.

https://ufile.io/jkezu If anybody cares to give it a try.

I don't; my owner does - not likely to get that info.

You owner has been very generous so far...
Damn shame, you could have made a killing modding pascal.

I think you need to find and parse three tables in case of nvidia: 'memory type' table which lists memory types supported by bios, 'timings' table which lists all timings without memory clocks and memory type and 'map' table which maps memory clocks+memory type to 'timing' id.

'timings' table starts at offset 0x2e40a from bios start, 'timings' are

Ok...this is clearly above my knowledge. How would you go about optimizing the straps?
I might be wrong, but we could use this https://gfs.nvidia.com/ to get the modded rom signed.

Don't have gtx's now to test if it work.

This is obviously not only for me but for the community as well.
Perhaps doktor83 can make something of it...the tool is there. Who shall be the first to crack the mighty Pascal!?

This is obviously not only for me but for the community as well.

Major part of community here is 'endless horde of noobs who done nothing but want profits'.
Sorry I don't give a f!!k about such community and consider expression 'for the community' a swearing.
