MINING RIG 6X GTX 1070 VOLTAGE ISSUES

[mmcruz1979]

Hey guys, I tried replace the risers, power cables, turn off 2 GPU's so 4 can be connected just to ONE PSU(i have 2), and nothing seem to fix the issue. The voltage go UP and DOWN so the machine lose speed. Any help? Please see the video in the link bellow.

How do you know you have voltage issues? You need to describe your hardware setup, what you have done to troubleshoot, and what you are talking about with voltage issues before anyone can give you any useful suggestions.

Ok,

My setup 6x 1070 GTX, asrock mobo, dual core intel proc. , 4gb memory ram, 2x psu evga 850w and 650w evga, 6x risers, ssd 64gb.

Please anyone?

it is because your gpu1 is working for your display rendering too while mining
plug your hdmi cable or monitor cable in mob and use igfx for display
it will sort your voltage issue and moreover increase the stability of your miner

I did this sunday, i turned on the bios primary video onboard video card and plugged a vga cable from the monitor to the mother board instead using the GPU video port. But i still have the same issue. IGFX automatic goes on when i use the onboard video card or i have to install it?

Thanks

I got  what voltage you mean . The problem is that GPU set against the Power Limit and drop the frequency and you see hashrate drop and the sawtooth on voltage graph in AB
 Try the following: At first unlock GPU voltage  management in MSI AB. Then correct the curve Voltage-Frequency (Press Ctrl+F and move plot points by mouse or keybord up-down. It would be like that:

But mine is not showing  curve, if you see the video at 1:07 you will be able to see my settings.

How I setup igfx on windows 10? I tried to download but doesn’t let me install because is not compatible.

Thanks
