I often find OP ask for help with troubled GPU's Rig with a bit info they gave. Just tried to make it clear, that kind of post won't help.

Applies to anyone asking about troubled GPU's Rig and tried to find the solutions.

First, we're not a mutant with mind-reading ability, and we can't read your minds.

Second, Troubleshoot isn't simple. Not so simple while you hit Enter with your foot finger.

...and many more reasons.

So, please describe to us your problems as clearly as possible.

Describing your devices and software, including:

• GPUs (including Series, Type, Brands, Memory sizes, Memory type, everything that you know about)
• Motherboard (including Series, Type, and everything that you know about)
• PSUs (including Series, Type, Brands, Wattage, etc.)
• Processor (including Series, Type, etc.)
• RAM/Memory (Including Sizes and everything that you know about)
• Storage Drive (Including type and whatever that you want to tell us)
• Risers (whatever, as clear as possible)
• Operating Systems you are using.
• GPUs driver you are using in the current situation.
• Overclocking Utility software (Including setting you are using)

Some people assume this info above isn't needed, but I can say for sure, it's essential things.

Describing your problems, including:

• Your act that was causing this trouble, in other words, what you are doing with your Rig before you get in trouble. (If this trouble suspected caused by your act before)
• If this trouble comes itself, just describe to us as clearly as possible.
• What have you tried to do to fix that problem? Tell us as clearly as possible.
• Add pictures when possible.

Don't forget to Say thanks, when solved and lock the thread after.

Additional tips: If possible, provide testing tools needed and also devices spare (PSUs, RAM, Storage drive, even mouse, and keyboard).

Maybe someone wants to add more info required, go ahead. It now seems enough.

If it's a duplicate post, I'm sorry! Just tried to make this forum better. Let's start with little things, if you don't care, Ciao Adios!

Increase virtual memory (Pagefile) at least to 16GB, greater would be better (adjust to your storage capacity).

For normal uses it's fine. It would be different for 24/7-365. But I absolutely agree with "to keep PSUs cold", that's why I'm adding more cooling systems near my rig. I'm using Peltier since Air Conditioner isn't my options, lol.

that's better


It would be safer and would keep both of your device (PSU and GPU)  and another part also in good condition, at least for an extended period.


With 1200 input and 1100 output, of course, you should choose Evga with 1300 Wattage.

Wow...Phill
You have a lot experience with many PSUs brand. Yeah, agree, whatever its brands, when pushing to the limit would break faster. And some brand has excellent durability when given a bit nor middle push, and the other would get a bit damage such as melted.

glad to hear that.
Good choice then you aren't made dizzy with the driver issue. Ah.. you are so lucky, sell old one then get the new one faster.

Who are you then?
Are you OP's alt account? Sorry, no offense.

Back to the point. Yeah, that's what I've done with my rig that has the same issue with OP's rig.

One other method that I know is copying a driver file to one different driver version but seems isn't working well for me.

OP - do it yourself, if you are using downloaded bios mod, possible you'll get in trouble. If you aren't familiar with manual mod bios, just use one-click version (like people above said). Even, if you are too lazy with one-click and you find someone that want to modify your bios, give them the original bios of your cards.

Using VPN would increase your stale shares. Like mentioned by a few people above, when you are using VPN, it would be increasing your latency to the pool server (assuming you are pooled mining). Most of your Shares would be late to pool server (we called it as Stale Share).


Try it then go back here after.


NiceHash isn't mining pool, but they are a Hashrate marketplace. If you feel stable, may someone that renting your Hashrate will be troubled.

I'm doing it with 16.9.2 and 17.xx. Mixing R9 and RX series, My R9 get the best performance using 16.9.2, but RX needs the newly driver.

Clean your driver, then install one of your drivers first, until the end of step will be better (but I don't, only up to extracting process). Then install the 2nd driver, up to extracting process only. It is the way to get a folder named "Packages" on each driver series.

Update all of your cards manually through Device Manager. Select driver version for each card in AMD folder on Drive C. Example, your RX 580 need driver (A), so select driver (A) on AMD folder, then select driver (B) for your Vega.

Blue Screen mostly caused by an incompatible driver or may driver signature check. So, if your cards have been mod, don't forget to patch it.

In the current situation, I agree with the suggestion above. Except you want to expand more setting with your cards. With more power space you can expand your cards setting, without worries.

That's it.
For new series like RX one dummy video output in one rig, it's enough, or straight to which card that troubled.

For old series like R9 family, sometimes need a few dummy video output.

I guess you are using AMD cards, am I right?
It's happened to some AMD cards. But don't worry, a dummy video output without connecting to monitor is more than enough. You can use HDMI adapter or something else that you can use on your mining cards output socket.

Efficiency means how much power from the wall would be drawn by the PSU at a current output power.
You must give more power spare at your PSU. Look what I've done with my RM1000i:

In certain situations, your cards will draw more power from your PSU, ex. When your cards adjust fan speed to keep temperature, and it will draw more power.

Point taken!
Really, I like what you do. When we know the key, with whatever devices we have, we can do Solo Mining. Keep going!

It seems they try to do "Solo Mining" to their own mining pool, so they were asking you to build private mining pool, right? xxcsu has given you the link to do it.

I meet someone that do solo mining on ETH. 31,5 GH/s from 900 GPUs, solving around 2-3 block a day.


You can see its post here: https://bitcointalk.org/index.php?topic=2861658.msg32772992#msg32772992

Never mind!

Technically full patch wouldn't adverse effects for mining process, Pixel Clock and Refresh Rate patching, used to allow higher resolutions and refresh rates. While the mining process using computation mode, so high resolution, and refresh rate didn't affect much in the mining process

Atikmdag patcher used for modded bios cards, to bypass driver signature check by the system so that the system will recognize those card. Unverified driver signature may be causing BSOD.

If your hashrate 50% or more from the Global Hashrate, 15 minutes "may enough", but also you need to consider coin's Block Time. Based on my experience, ideally one hour.

Have you tried one only card plugged?
Did you find something strange on cards or PSUs, melted or whatever? Just for making sure no physical damage.

You can start with standard troubleshooting. Check all cards one by one (plug cards one by one to mobos).

---

And you can report all of the progress here. All members here would help you.

As long as your cards made a profit, even if just a bit profit, no reason to stop it, right?

---

Yeah, make sense.
OP - may you need to check your card's temperature.
