Decoding info I saw, but dont understand it, dont know what these values mean.
So ubermix will work also on RX 470 4GB with Samsung memory?
I have also 470s with Hynix and Micron, if you want to test it, let me know...

I have Uber-Mix 3.1 on RX 480 8GB and RX 470 4GB they mining almost same on XMR.
I will PM you file with timings, you can test them all and let me know which one is best.

It's decoded from HEX but also those numbers and letters like 777000A means lot of things, there is another tool to decode this to correct specs. It looks like this. Again all is in that first post I've posted here.

Code:

####SEQ_WR_CTL_D1####
DAT_DLY = 7
DQS_DLY = 7
DQS_XTR = 0
DAT_2Y_DLY = 0
ADR_2Y_DLY = 0
CMD_2Y_DLY = 0
OEN_DLY = 7
OEN_EXT = 0
OEN_SEL = 0
ODT_DLY = 0
ODT_EXT = 0
ADR_DLY = 0
CMD_DLY = 0

And so on it's long Cheesy

So, I have used the BIOS provided and I verified in GPU-Z that the memory is DDR5 (SAMSUNG) on all cards. Bad news. Somehow it is STILL hashing only at 17MH/s now! Even if I restore to original BIOS which was actually exported from ATI Flash and not GPU-Z. Now, what doesn't make sense is how come it does not return to the original hash rate even though I flashed to the original BIOS. Additionally, I did update to EthOS 1.2.2 from 1.2.1 and everything went smooth. Does modifying BIOS in Windows also require special configuration in EthOS (I assume so and I do have global mem set to 1250 and just set globalcore to 2000).

I am completely lost as to what is going on. I do have 3 more identical cards sealed in the box which I am going to open, benchmark to check if they get to 24MH/s and extract the BIOS to hopefully restore to 24 and not lose money by being down.

All help is much appreciated if you can solve this for me, I would love to send you a donation.

I don't mine ETH neither have RX 5xx series and ETHOS... It should work if this bios is correct one. Try 1300MHz clock and 2000Mhz memory this should be running like hell. Could you try to mining in Windows? Also in Windows you maybe need wipe drivers after flashing. It sometimes doesn't work very well. Try flash orig bios, reboot, then modded one and also run DDU. Reboot and install AMD drivers, apply patch and reboot again. If it's still not working there is problem with card or with bios.

That 470 4Gb where you have UberMix 3.1 is Samsung mem? I just really wonder if I can use it on 470 gfx. Everywhere is written it's for 480/580... I would like to try that on my Samsung 470, but dont want to brick it

On my 480s the 3.1 is much agressive and I am getting mem errors fast. I am trying now 3.2b (didnt't found 3.2 final non beta) and it looks more stable but on higher frequences...
