@Isnobad great tutorial, following it I have reached 480-490MH/s with my RX550 2GB (more than I could with Win 10).
But I have one issue, I cannot see GPU temp or fan speed anymore (before doing the changes here I had 400MH/s but the GPU was seen as RX560 and I could see temp and fan speed), the rig stats show as I have the GPU offline, and I have only CPU’s. What to do?
EDIT: I see now in agent-screen this error:
cat: ‘/sys/class/thermal/thermal_zone*/temp’: No such file or directory
MH/s 
mh, ok? “based on a fresh flashed Hive” ?
http://download.hiveos.farm/hive-0.5-32-20180228.zip
Maybe:
boot up Hive,
Stop Miner, (!)
Shutdown,
Boot (no miner active)
go SSH
apt update
apt upgrade
apt install lm-sensors
sensors-detect
(y to all)
reboot
my 550 was at 63.8 h/s, then I followed the guide, and it is way better, but still not as BLKro says. I cannot achieve anywhere near 400 h/s. What am I missing.?
Totals (ALL): 459.3 456.0 0.0 H/s
Highest: 459.9 H/s
@StarLog You have not read the whole thread, not even the first post if you are using Claymore Dual. You need to be using sgminer or xmr-stak with 2 threads per GPU. I for one am using xmr-stak with the following AMD config override:
“gpu_threads_conf” : [
// gpu: Baffin memory:1664
// compute units: 10
{ “index” : 0,
“intensity” : 432, “worksize” : 12,
“affine_to_cpu” : false, “strided_index” : true
},
{ “index” : 0,
“intensity” : 432, “worksize” : 12,
“affine_to_cpu” : false, “strided_index” : true
},
],
“platform_index” : 0,
For sgminer something like this should work (not tested myself):
“rawintensity”: “432”
“gpu-threads”: “2”
“worksize”: “12”
@Isnobad I had a fresh install but went back and reformatted the usb stick and reinstalled from scratch, not it works, but I still see the GPU as RX560 although it is an RX550. At least now the temp is showing, and it’s been hashing away nicely for 3 days now, with 480H/s constantly (not MH/s 
)
@BLKro I am not sure how to change the screen to reflect xmr-stak. This is what I am getting after applying your config override.

How do I change the Custom Tuning from Claymore to xmr-stak.
I cannot change the wallet to get ride of claymore.
I cannot now attach another image to this thread so making a new response below
This is for above comments.
So if I remove your override, the xmr-stak runs the miner, what am I missing in the override.?
Thanks for the help, this is my dev rig, once I get this working I will apply many more cards.
Try changing platform_index from 0 to 1
Also to get rid of claymore is unnecessary, but you can do it by deleting every info from every box in the claymore tab… It is sufficient to select xmr-stak as miner in the rig options.
Same thing after changing, and reboot…

xmr-stak exited, waiting to cooldown a bit
Looks like you’re on the new xmr-stak, try this:
“gpu_threads_conf” : [
{ “index” : 0, “intensity” : 432, “worksize” : 12, “affine_to_cpu” : false, “strided_index” : 1, “mem_chunk” : 1,
“comp_mode” : true },
{ “index” : 0, “intensity” : 432, “worksize” : 12, “affine_to_cpu” : false, “strided_index” : 1, “mem_chunk” : 1,
“comp_mode” : true },
],
“platform_index” : 0,
but also update to the latest hiveos which should have xmr-stak 2.4.2 (.0 and .1 are buggy)
Well, it atleast liked the config. Not sure if I am getting the max…
Only getting 142 h/s on the GPU, not anywhere near yours.
When I download the vbios, where is it stored.? I cannot find it.
I think you need to mod the bios for the higher hashrates. At least mine are modded, don’t have an unmodded one to compare to your’s.
After you click download vbios, click reload up top after a few minutes and you should see this:
Click to save the file to disk.
Please tell me the correct config for 5 cards on xmr-stak 2.4.2. If you do not touch anything, everything works, but a small hashed.
BLKro,
I finally got a mod’d bios that works in windows and here.
Does this look good?
This is the one I wanted to upload, WHY does it not let me delete the post, or the picture, and add another.?
@StarLog to me it looks ok, could be a little bit better but each card is unique. One friend has 2200 mem clock, and has 550h/s while I can only go to 1900… and I have 480h/s
