Hi guys, please can you explain:

1. How Overclocking > Powerstage settings works?
2. What's the default value?
2. Is there possibility to disable this function (if i understand, i can modify voltage control directly in bios)?

My system is unstable even with default settings a i can't figure out where is the problem (i suspect it may be Powerstage settings).

I use Sapphire Nitro+ RX 570 gpu's.

Thank you.

Is it better now ?
Anyway there is no proxy.
In those cases you should use vpn if your provider is getting blocked.
Cloudflare is blocking your ip and has propably good reason
I know its not you but cloudflare treats whole ip or class like threat

This tool doest work with amdgpu-pro its only for fglrx so R380 gpus.

The second way isnt good bedause recompilling eberytime kernel would make no sense

Tytanick, did you try underclocking and undervoting describe here?

https://www.phoronix.com/forums/forum/linux-graphics-x-org-drivers/amd-linux/918649-underclocking-undervolting-the-rx-470-with-amdgpu-pro-success

I do not see any modification under /usr/src/amdgpu-pro-16.60-379184

Tytanick, would be great if you added this to the utils folder !

All scripts in utils + system config could be changed by me in auto update -thats why i dont want anybody to change something by himself
Also i cant guarantee anything that you mod in system will presists.
I would have to look in everyones rig if they made sone changes It is impossible. Thats why i dont support it and thats it
You are doing custom things but you dont know when it could be changed by global update.

Tytanick, sorry I should have worded differently.  I was not asking you to push updates, I just wanted to validate that if I spent the time to update them myself that your auto updates would not overwrite what I did.

Fixed It Last Sata plug on the cable was shorting out, Simply used a new cable on the 6th gpu and wallah Perfecto all 6 cards running! Thank You anyone who helped by giving suggestions!

Thank you.

if you open a github repo for the codes, we can help too. Just consider it.

An Update on the rig, Last night I built a 6 Card Msi Armor 570 4gb rig for myself. 6 cards work perfect right out of the gate! This morning I was trouble shooting the rig, I went card by card all was well until i added the 6th gpu. fails just like before. I take the 5th gpu out and leave the 6th, Works fine. Take the 6th gpu out leave the 5th, again works fine. Swapped mobo slots aswell and still no dice. Pretty stumped and just thinking this is a one off mobo that doesn't like 6 cards.

I think i can implement this into R OS version like i did with RX OS.
Its stimple few lines. I will add this to my todo list

tytanic, I connected to my miner with ssh and found the sh scripts in /root folder.
Now I can modify the clock setting script to set the clocks individualy. I have 3 cards (r9 280x) and not all of them are the same brand and I have some cooling issues so I'd like to downclock the hotttest card to make them run cooler.
I need
1050/1500
1000/1450
850/1350

I can make this by modifying and harcoding the clocks values but I think they may be overwritten with automatic updates.
Anyway that you can add this functionalty to the system?

Maybe you should put those scripts and other codes in a github repo so we can contribute.

You can press update button yourself.
I wont push this change to all rigs becasue it can cause may problems but mostly it should work fine.
Press it yourself


I guess you need custom bios mod with proper timings.
I am not taking care of it.

Somebody had try this tool to set Vddc voltage in Volts?

tytanick, is their an issue with updating the drivers in smOS.  I show 16.30 but would like to go to 16.60 and I dont know when you update your os remotely if it overwrites the driver change.

tytanick,

The new kernel fixed an issue that popped up in relation to the newer AMD drivers. I referenced the ethereum forum link where ogodagirl said to use the ethash-new.cl kernel. That said, when I tried to just copy over the kernel file, the build of seminer-gm wouldn't recognize this new kernel.


Anyhow....time for tale of the tapes.....

After more than 12 hours of undisturbed hashing, it looks like Claymore is still the winner in average hashing efficiency. The two machines weren't equal but as close as I could make them at the time. Machine 1 had 3xRX470s with bios mods running the latest Claymore:
Reported, Avgerage, Effective
77.2 MH/s   81.8 MH/s   76.6 MH/s

The second machine had 2xRX470s with bios mods with the latest build of seminer-gm running the ethash-new kernel:

Reported, Avgerage, Effective
0 H/s   36.7 MH/s   39.6 MH/s

As you can see, it comes down to 25.5MH/s per card with Claymore vs 19.8 MH/s per card with Sgminer-gm. I'll test again some more in the future but for now I'm going to go back to Claymore even with the thrashing. Maybe things will be different with an equal number of cards in each machine or maybe the big difference was just better luck. Future testing will tell but I've got to rebuild some stuff tonight and I'm out of time to test with.

Hi T - can you update the sgminer-gm v5.5.5 -- kernels like "ethash-new.cl" are missing. Thanks

some fact-finding from decayinjack a few post below:

===
The compile of sgminer-gm included with SmOS didn't have the new kernel but the latest compile from source did. You'll want to build from source and then move both the kernel and sgminer binary over. I tried using just the kernel but the older version of sgminer didn't recognize that it was there.

I'm having the same exact problem he is. My RX 580s average approximately 3.5 mh/s less on smOS compare to windows. Now, I'm not foolhardy enough to throw around absolute statements concerning the root cause of smOS's relative poor performance running my RX 580s relative to windows based solely on my own observation, two people's observations, or even three people's observations. Maybe you should give reserving judgment and avoiding jumping to conclusions a try. You may like it.

I have a rig with 4 Asus 470s and 2 Asus 570s.  Works fine. No problems. No need to update drivers or kernel.

There's something else wrong with your rig.

on v1095 I am still maxing out at 24.5 mh
