you are ventilating open air/oxidation and chip chinese pcb and here is result.Winter times even you think dry there is many particle in air can make oxidation fast, chinese pcb are not protected from oxidation.and also it looks like water leak happened.and also measure humidity outside too.Rigs dry air fast so measuring it inside will be not accurate.

How about your room temp.? Maybe you are living on a cold place that is why it still getting corrosion.

The ideal temp is around 60 and 75 degrees Fahrenheit if you get lower than 60 some components will always fail.

Perhaps thermal shock due to temperature variation is causing condensation. Extreme variations in room temperature cause this effect.

your meter shows 40 for humidity

you are not near salt water

not show why you have a corrosion issue.



Ie 65% humidity it is a no brainer

Near the sea or a bay  also make it easy.


But 40% humidity is decent

this is a gpu question it belongs in alt coins.  I asked the mods to move it.



Buy a temp/humidty gauge

show it to us

also are you within ½ hour drive of salt water?  Such as an ocean or a bay.

Can anybody share the telegram commands they use for multiple rigs?

Use the screen utility in linux to keep the script running even if you close your ssh session.

Hi Guys

Firstly, @Kasmetski for the amazing work on this rig resetter. It's exactly what I was looking for after weeks of headache with my rig hanging and I must drive 40 miles to reboot!.

I have purchased a Raspberry Pi 3 Model B and installed Raspbian just now. I have also enabled SSH and changed the password for user Pi for security.

Now, I am on Github but I'm not sure what to do from here...

Should I run: to download the file to the default directory?

After this, github mention to run:

But I checked in Github file list I don't see any auto-hard-reset-arm7.tar.gz filename.

Please help, sorry for the noob question... I'm sure I am overlooking something.

Basically it's normal for them to crash from time to time. It depends how frequent however.

I would just lower your memory clock to like 1900Mhz and it will hash at 27.5 but it will be stable at least. Not all GPUs can hash at 29Mhs.

For your power consumption you should undervolt each GPU by 100mV and it should still be stable and consume much less power and be much more cooler.

When I say custom straps, I mean straps that someone has encoded for a particular card, not a simple copy/paste.  I think ohgodagirl does custom straps for $$$.

I would use windows for initial setup at least.  Only modify straps, don't modify anything else in bios.  Run miner.  Use overdrive or afterburner to increase memory clock until you either get memory errors in hwinfo or the hash rate stops increasing, then lower the mclock a bit.  Lower cclock until hashrate decreases.  Last, lower core voltage as much as possible while maintaining stability, then increase it a little.  Sometimes modifying the core voltage automatically modifies the memory voltage too.  If not, then lower memory voltage as low as you can while maintaining stability (check for 0 memory errors), then increase it a little.

Once you've determined the proper settings, you can use them in linux by either programming them into the bios, or setting them in the claymore command line.  There may be other ways, I don't mine eth on linux.

If you don't lower the voltage, your rig will draw way too much power.  Properly undervolted, an 8x rx470 rig shouldn't require more than 900W if mining only eth.

You may not be able to push them to 30 mhs without custom straps, although 29 is usually doable.  But you need to accept whatever hashrate you get that is stable, even if it is 28-29.  Not all cards tune right up to 30 without custom straps.  And even ones that do, they may not be stable, and it will probably cost you more in the long-run to push your cards to their absolute limits.

In general, people who are relatively new and don't entirely know what they're doing expect way too much and push their cards too hard.  If you don't really know what you're doing, and instead are just following guides/instructions online, you should play it safe and be conservative.  Under those circumstances, 230 mhs at 900W, and stable for weeks or even months, should be doable.

Good day, but what you do not like the Windows?
As far as I know the operating system does not affect the speed of the cards.
You need them to properly disperse and flash, the network has a lot of information about this.
But the main thing do not forget to keep the original BIOS firmware.
