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 Grin, 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.

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.

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 Wink

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.

Guys, I'm in search of advice. I have a Sapphire Nitro rx480 card (non plus model, Micron memory) 11260-20-20G. All the modded ROMs I've ever tried make the Claymore's miner work for about a minute or two at 30+Mh/s before crashing the Windows 10. The recent one from this thread (thank you, doktor83!) worked for about 15 minutes at 29-30Mh/s before crashing the drivers and rebooting. So, can't make it work in stable mode.

I also have a strange problem - the Watttool 0.92 doesn't show anything for my card, everything is zero. Also, neither Trixx nor the GPU-Z show the GPU temp. The latest version of Windows 10 with Crimson 16.9.1 drivers (newer drivers do not recognize the card with the custom bios for some reason).

Also, what is the reason that some of the modded ROMs are 256KB when the original ROM dump is 512KB?
I need to know if it is the problem with the card or I'm doing something wrong. The card is hashing at 25Mhs on default ROM (see the link below for the original ROM).

Bad drivers or you too much overclocked cards, probably memory errors.
You better not use modded bios you can do your own, much safer. Link to guide in my signature.

Hello guys!

A little help needed here Smiley
My card is an ASUS RX470 STRIX GAMING 8GB OC with micron memory, and I'm doing dual mining ETH+DCR with claymore. And using afterburner for tuning.
I tried a lot of variations but my best was 25MH/s ETH + 780 DCR. (or 26MH/s single)
drivers: 16.9.1, 16.9.2, 17.5.2
gpu: 1000, 1025, 1040, 1050, 1100, 1150, 1200, 1250
mem: 1750+
straps: 1500, 1625, 1750

At the moment I'm mining with 16.9.2, 1100gpu, 1900mem, 1750 straps (this seems stabile and the best so far)
Highest was 28.5MH/s with 17.5.2, 1200gpu, 2100mem, 1750straps, but GPU failed over and over again.

Also tried WattTool, and copied the settings Insider posted, but could not get better result at all, and most times my pc crashed.
There you go Smiley

I have sent everything to BuriedONE Blockchain Youtube channel, he will make video for it soon
Good luck Smiley

My goal would be 28-30MH/s if possible. I would be glad if you guys could help me.
