Gigabyte RX 5700 XT OC REV 2.0 samsung memory bios mod issues

So I am having the hardest time getting my gigabyte 5700 xt OC with samsung memory to bios mod. I did all the normal steps using red bios edit but for the life of me cant get it hashing. I also cant seem to find any info on these cards with samsung memory. Does anyone have a working unsigned BIOS for this card? Any help would be appreciated.

I tried a lot of methods on all sorts of cards with Samsung memory. They suck! I ended up going back to stock on all my Samsung 5600 and 5700 cards. My Micron cards work great 58Mhash on 5700

Ah this makes sense then why I’ve been having nothing but issues trying to mod my samsung 5600! I guess il just leave it stock.

Yes, leave it stock for now. I haven’t figured it out for samsung memories. I heard other people have BIOS that works, I just don’t have it. So I’m leaving all my samsung cards stock BIOS and low memory clock setting. They say don’t exceed 910Mhz, but some cards only run at stock 875Mhz.

Hey I actually ended up rolling the dice today and flashed a modded bios for a Powercolor Radeon 5600 XT on mine and it works really well. I guess apparently even though my GPU says “Samsung” in Hive, it has a combination of Samsung and Micron memory chips.

I verified the part #s for the memory using RBE to check the stock bios against the modded bios, and they matched. I’m not able to undervolt down to 680mV, and get 41.5 mh/s when memory is 900.

Before I used to struggle to get 39 and usually would become unstable. I’m able to get 42 mh/s if I boost memory to 910 but i’m not quiet sure it’s stable so im sticking with 900 for now.

Hey everyone, sorry for the late replies. I was able to get help from Crypto Peasant over at red panda mining on discord. Here are the timings I am using for my Gigabyte RX 5700 XT.

I use the below for 1550, 1800, 2000, 2250. Been running this timing on all of my samsung 5700 xt’s, not just the gigabyte.
