can you control arbitrary number of miner hosts? 100-s and 1000s with this with one click?

can you set core clock exact or is it an offset?  if it's an offset can you do individual gpus or is it global?

also for power, do you set mv or is it a percentage?

thanks

You can set core clock with space like: 1250 1200 1167 ....
For PWR is the mv value not percentage.

On linux is not possible or not very simple to undervolt Memory so in HiveOS you have DPM Core Voltage Mem State to undervolt. "Mem Voltage" VDDCI is not working (support?) on Linux....
You can try to play with powlimit on Claymore and that it...

Does anyone have experience with using hardware watchdogs with Hive OS?  If so, what are your experiences with them?

I was looking at these:

It looks like they are supported: (well sort of)

Based on my limited time with Hive OS, my understanding is that the series of event goes like this:

1. Hashrate watchdog it triggered due to hashrate dropping below set-point
2. Miner restart initiated
3. If miner restart doesn't correct issue, reboot takes place
4. If reboot fails, then hardware watchdog attempts reset
5. If hardware reset fails, then hardware power cycle takes place

But if you have a frozen rig and #2 and #3 don't work, how is Hive OS going to "reach" the USB watchdog to perform either 4 or 5?

Maybe the above is not how it works, and instead the OS on the mining rig sends a keepalive signal to the USB watchdog, and when that fails, a hardware reset is attempted.  And failing that, a power reset is attempted.

Over the years, I have had computers lock up so hard that the only thing that would get them back, was to physically remove power and restore.  I guess a USB watchdog can't do that unless the output from the on-board power relay was driving a much larger external relay that can kill power to the rig.

I know with SMOS, SRR (SimpleRigResetter) is the way to go for hardware watchdog, which gets around the issue of using a USB dongle that might not be reachable if the rig is frozen.  But as far as I know, SSR does not work with Hive OS.   So I was curious what everyone is using with Hive OS.

Thanks!

Halo i want to use Hive OS for my next RIG, but i have some stupid question.
1. How many card maximal to use on hive os? have limitation?
2. Can we Modding GPU Bios at Hive OS?

I think you're right and SSR will indeed work with Hive OS.

Looking at the Linux script, this is all there is to it:


So the script sends keepalive packets to SRR over the LAN, and if the stop coming, it will close the power pins on the mobo.  I guess the only thing that Hive OS won't do, is to be able to show a message that a given rig was reset via SRR.  I guess it will just show the usual "rig rebooted" and the rig will actually end up rebooting, even if frozen.

I just gotta say how much I love HiveOS.  Updated regularly and so many useful features.  Dimaferm rocks!

 

1 = 19 GPU
2 = You can backup bios and flash bios. Modding bios have to be done using windows Machine.
