Hello I would like to know your opinion on the rig a 7gpu,

I have to mount a rig with motherboard msi z170 pro carbon + 7 rx 480 nitro +

I get 210mh with eth only.

But in dual mining I find my rig not very stable, a lot of bsod and driver loss.

You have the same problem?

Would you advise for more stability? Huh Huh

Hi, i had a similar problem with dual mining, try going your core clock a bit lower when overclocking, this worked for me.
I mine with STRIX RX 570 x6.

Whats your power supply?   those issues are gpu instability due to either high Temperatures, too much undervolt, too high overclock, or unstable current.

I have a evga 1600w G2.

My OC:

Core 1200
Memory 2150
Voltage -50 in msi AB

I uninstall driver with ddu, and reinstall driver 19.9.1 to try.

You can always easily diagnose the problem by running the cards ALL STOCK
- Lowering your gpu clock  to stock or lower
- Lowering your memory clock to stock or lower
- applying default voltage.


If they still hangup, start removing one card at a time.

If you still have problems, it may be a driver/software problem

most of the time is the motherboard the problem here, are you sure thta motherboard can support 7 gpu? maybe there is too much wattage needed for the motherboard in dual motherboard to fee 7 gpu and it can't do it, so the system restart to prevent damage

Thank you for your answers ,

But even with coreclock of 1150.

It reboot regularly, and I do not see any error log file.

In simple mining eth no problem,

I have problems only in eth / pasc

Even with eth / sia I have less problem.

The most stable is 6.

If you want 7, I suggest you use Evga as your power supply.

What does manufacturer of PSU have to do with it? Nothing.

Just reduce amount of OC you have as when dual mining you are maxing out your GPU and it gives errors that crashed miner and system. Run all cards stock and slowly increase OC until you notice any crash/instability. Then go back a step and leave it there.

Thank you for your answer,

What is strange is that before ca walk very well,
