HI all,
i had the same issue with the release version of HiveOS, i have reflashed the SSD with Beta 146 and it is working.
However should i update the GPU Drivers? i am using Sapphire Pulse 5600XT and getting 40mhs per card, i think perhaps they can do a little higher?
When i try to wget the drivers it seems it cannot find them, it sits for ages doing nothing.
Mod the BIOS, I was getting 50mhs per card as a standard, With the BIOS mod Im getting 57 just under 58 mh/s per card. Makes a big difference over the amount of cards you have. You will also draw less Watts in the end.
Edit: This is with RX5700’s
These are 5600XT not 5700XT, not sure they can do 50mhs let alone 57mhs heheh
haha yeah, I made the edit just after… But Im sure you will still be able to push just that little bit extra out of them with a BIOS mod. Go look at voskcointalk.com for a Modding guide. I followed that to the T and thats my results. 
Oh and mine are not the XT version. They the standard version 
Oh awesome thanks for the heads up! will definitely check it out
same is happening to me, but with 6 gigabyte rx 5700. They are mining perfectly fine so as long as nothing wrong happens i wont flash the bios or update those drivers
help please
Hi there, What I did to fix mine was put them into a windows PC and check drivers and see if the card actually works. after I got them working with the correct BIOS and drivers I then modded my BIOS. Is the card new or was previously mining? I am also mining on the Beta version of Hive. That also helped me get the correct Hash rates
aynı sorunu yaşadım. o kartı tek çalıştır bakalım çalışıyor mu? biosu bozuktur kesin. bende öyle oldu yeni bios attım düzeldi.
The problem was solved when I switched to teamredminer thanks
I am also having this Unknown GDDR6 xxx-xxx-xxx issue. I purchased a batch of 8 xfx rx 5600 xt thicc ii and when I went to load the 5th it gives this error. I thought maybe it was the card but it happened with a card that previously showed up. My other rig is running just fine with 7 xfx rx 5700 xt triple dissipation. The set up for both rigs was the same. I can’t get my 5600 rig to take more of my cards though.
Same issue here with 5600 XTs. I can only get four to work in my rig. When evener I add a fifth I get the Unknown GDDR.
Hi man, any updates ? Im having the same issue as you in my 5th card.
Hi man, any updates ? Im having the same issue as you, my 5th card doesnt work, its Unknown GDDR6
If you have not done so ensure that in BIOS settings you have ;Above 4G Encoding’ set to ‘Enabled’
That was my problem.
Have you try this command?
hive-replace -b -y
Like this video:
Hello
I have talk with HiveOS to solve this probleme. He gave my solution and it was successful for my RX 6800.
"Try to update system image.
To remotely upgrade your Hive OS image
You can log in to your worker with Hive Shell:
And enter the command:
hive-replace -y --stable
The Hive OS image will boot, unpack, and install automatically.
Please note that if you have a slow Internet connection, downloading may take a considerable amount of time.
To prevent the Hive Shell session from interrupting (by default, 30 minutes) perform periodic actions in the window (for example, a mouse click)
After the update is completed, the rig will automatically reboot and the last stable image will be installed"
