Unknown GDDR6 sapphire 6800xt SE

[Pedar57]

Hello guys

I have installed SAPPHIRE nitro + 6800xt SE on my rig but can’t get any hashrate due to “unknown gddr6”. I even reflashed my hive usb with latest HIVEOS stable version BETA image. Nothing happened.

I have used Intel G5420 cpu and Asus b365 plus motherboard. I even used Gigabyte b365 hd3 motherboard. Nothing happened.

Please help.

Thank you. I just downloaded Beta image last night and flashed a new 16 gb USB memory. It didn’t work.

What is the Linux kernel version on Image that you’re installed?

[Pedar57]

System type linux
Kernel
5.4.80-hiveos

[HaloGenius]

You downloaded OLD version

Latest Stable image has signature 5.4.0-hiveos #118
Latest Beta (which currenly even older than Beta) 5.4.0-hiveos #99

I’m pretty suggest download Stable Image from web site!

Beta Image

May use the latest drivers and experimental features.
Added support AMD RX 6000 series (“Big Navi”).

I downloaded zip version of Beta image.

Thank you. I will try again.

Thanks for your help.

I downloaded Stable version (not beta image ) and reflashed. My Sapphire 6800xt cards are now up and running. No more " unknown gddr6".

My kernel version:

System type: linux
Kernel: 5.4.0-hiveos #108

Hey there,
I have a couple of Sapphire 5600XT with samsung memory (113-D1891011-O05).
I tried manually editing their default bios by copying the 1550 lines to the higher mhz ones.

When i flash the bios back to the cards and reboot hive i get this “Unknown GDDR6” and the cards wont mine at all.
I need to reflash the original bios in order to get the cards back to working.
(my cards dont have a dual bios switch - not one i could find anyway)

I am on Kernel 5.4.0-hiveos #108 and version 0.6-204@210608.

What’s the suggested course of action here?
How can i get the bios to get recognized?
If i have to update the Kernel version, can you walk me through it?
Is there some ready bios out there for 5600 samsung memory 113-D1891011-O05?

Thanks in advance.

PS:
I had the same issue with another MSI 5600xt with micron memory, where i ended up flashing the Red Panda Miner BIOS, which worked great, gave me 4 extra MHs but around 30w+.

Unfortunately I cannot find the equivalent bios for my Samsung cards, so i have to solve this and get them recognized with the manually modded bios.
