BIOS and mods for Sapphire RX 480 8gb Micron Memory - 0.25 ETH reward for help

[reinerlee]

For all of you guys i made a custom bios from the one in the main post.
You won't need any wattool,wattman,afterbuner,trixx or any other software of that type, i set everything in the bios like Insider00 did with wattool, so :

Def gpu clock : 1144 Mhz
Def mem clock: 2150 Mhz

Mem straps 1625
VDDC (gpu voltage) set at 925mV
TDP 120w
Set fans to hold cards at about 70c, so you don't need fan regulation either

Before flashing remove ALL software that you used before for manipulating (wattool,wattman,afterbuner,trixx...).
Then clean all video drivers with DDU.
Flash bios.
Reboot, reinstall video drivers.

Test.

Enjoy

Do you mind create a rom that limits the MEM clock @ 2000mhz ?
I don't know what's going on with my GPU, maybe the room temperature for our place is too hot,
It's very unstable to run at 2150mhz for me. but solid stable at 2000mhz.


-------

Update:
I got it limits @ 2000mhz by using PolarisEditor for micron memory from this website.

It is hot weather in france and I have prepared dozens of bios with 10MHz steps, and 5W TBP/Maxpower, and my miner got few memory errors, and stepped back to 40MHz less, or to 10W less in TBP/MaxPower... it is happy now.

Now just need someone with real knowledge about Micron memory to make custom
strap instead just copy/paste

Thank you for your help, but are you sure this one will work ? have you tested it before ? i didn't flash it yet, but i used similar mod yesterday and didn't work, alot of people saying it's can't be modified, just want to make sure that u tried it before ?

thanks

I have not tried it however there is no reason it shouldn't work. If I had the card in front of me I would keep going even if that ment I had to start digging into hex. However I had to put together a separate machine running 16.11.5 to flash some of my samsung memory cards then when put back into a system running 16.9.2 they worked perfectly.

Side note if none of them work your not out anything however if they work and you chose to send me a tip that would be cool.

Woohoo, Who said Micron is sucks , Finally it's worked hashing at 30.3XX, after few edits in bios and Wattool,

Hello,

I do have a sapphire RX 480, with bios 113-1E353FU.O50 , also trying to find a bios that increase the hashing. Anyone around with this Bios modified and ready to flash?  Also more than happy to reward someone with the right file.

Please, let me know.
