Oh yeah claymore eth 8.1!!

Just dropping a note of thanks to Tytanick for his smOS and SRR.

Today is a big day for me because, just completed SRR for all my rigs, housekeeping of rom mods for all rigs, standardized all USBs/SSDs, upgraded my old hubs to gigabit switches, cleanup the network cabling, etc.....  for the past week nearly 100% uptime daily and full speed 45K sol/s total hash for ZEC (3.6GH ETH, 115Khs XMR) - thanks to SRR keeping each rig alive.  I can say, my small farm is almost lights out operation now and I remotely manage the farm from home more often now. More time with family, more sleep time and working comfortably from home.

smOS and SRR are really a good combination and have generated me good income - hope we will see the best mining OS becoming even better with useful features to help miners be successful in mining. This is one of my best investment and ROI.

Also, would like to add a word of thanks to Eliovp for his amazing custom roms for my RX480s, R9-Nanos and Pandaminer.

Accualy it looks and works nice, thx
I will look into it and if nothing will came up better then i will implement it.
Still thinking if separate window (tab) for chat wi good idea or should id implement something that ill be integrated into SMOS dashboard.
But still i cant pack all things into this dashboard

Also i am thinking should i allow wiring without logging.
There are trolls everywhere, so i am thinking ...... what you say guys ?

Hey tytanick, one of my rigs I am going through re flashing.  I notice when I do reboot from ssh I get alot of green OK's and 1 red saying failed unmounting /tmp and the last ok I see is a green ok reached target shutdown, but it never shuts down.  I have to manually power the rig off and start it.  Odd thing is one of the other rigs, I just went through and re flashed and it never hung.  Not sure what the issue could be. 

Just to be completely clear here.

Before others start to fly and think they can undervolt..

0 - 7 are the DPM stages for the core clock.

You don't undervolt, you just set your core differently on a specific dpm stage.

As an example.

Open up polarisbioseditor, you'll see that there are 8 stages for the core clock. 0 -> 7



As you can see here, on the left you have the preset core clock settings and on the right you have the voltage settings.
300Mh being the only one with a preset voltage offset.
The other 7 will be auto calculated by the GPU. (By adding Global VDDC Offset in the rom, this can be manipulated).

What happens here isn't really "Undervolting", the only thing that does happen is that driverwise the core clock of a specific dpm stage is being modified, therfore the voltage remains the same as it was previously on that specific dpm stage.

So you are basically forcing a specific core clock to run on a specific voltage.

It's like this example:



Which is

1. Definitely not stable in most cases as it's not being autocalculated anymore.
2. Not how it "should" be.

It's a way, i'm pretty sure it'll work okish, but i'm also very sure, if you start messing around to much, your gpu's will fail.


That's the difference between forcing voltage or adding a global vddc offset in the rom where the voltage controller starts calculating from a lower voltage offset.


Just to be very clear here, it is "not" possible to really "undervolt". This can only be achieved in the rom itself.

Oh and for the Fans, or better, the haters, i'm not bashing anything here, i'm just writing down facts.

Greetings!

Yep, Eliovp is right.
Its not the real "THE Unvervolting" but its just thing when gpu can use powerstage from for example 900MHz and overclock this stage to 1100MHz.
It works as undervolt, there are positive results but i also would not call this undervolt.
So i made corection, now its called "Powerstage"

Anyway it can do little more magic but still the full power is in custom bios.
Here is list what can be done with GPU bios using hex editor:

This can do anyone:
1a) overclock
1b) lowering powerstage in my OS
2a) simple copying timings form 1500 to higher values via PolarisBiosEditor

This can do only pro like Eliovp, wolf0 and few others:
3a) adding voltage offset (if its not present already)
3b) changing offset to lower and lower values (this is more less simple opreation)
2b) applying true custom timings (if you have the timings its simple, hard is to make those )
