Hi there. I don't know what the problem is as I'm having the same. Though I'm getting somewhere. Open after burner and detach your monitor. Make sure you can see all Gpu Power draw, and remove temperature so it doesn't take up as much space. Find your Gpu which looks unstable, then figure out which one it is. Now turn down your comp and simply switch it with another 1 on the PCI slot in your motherboard. Eg. Card nr 4 goes into slot nr 5,and vise versa.

This stabilized all my cards. And I haven't had a crash for 24 hours now.
Also, I stooped using any cards that's not Pascal.

There is no need to go with such a high wattage power supply for a new rig (assuming new cards). I run rigs with 6 x 1070's @ 100% TDP on an EVGA 1000 watt power supply with no issues. I do have mine connected to 240v for a bit better efficiency but it works fine on 120 as well. Every new card that comes out from now on will likely draw less power than its predecessor even with the big guns. Nvidia's Volta is due early 2018 now, and AMD well who cares but they are trying...

Also, you get the best efficiency when using 85-92% of the available watts. A rig that draws 900W on a 1300w supply would be @ 70% and a waste of electricity and extra heat for the conversion.

You're extremely wrong. Do a bit of research before you throw out an opinion you have no clue about.

It is quite easy to locate the power curve for almost any new power supply.  The best thing to do is figure out what your expected draw is, and compare that to the power curves.

for example an EVGA SuperNova P2 1000 is most efficient around 400 - 500 watts



So, if you were drawing 400w from the supply you could expect a draw at the plug around 420 - 425w (93% efficiency).

If you were drawing 1000w from the same supply you could expect a draw around 1080w at the plug (92% efficiency).

Lucky I live in a country that the power standard is 240v.

But on the downside, power is expensive so i always buy platinum+ power supplies and try and run them as close as i can to there maximum efficiency point.

i'm having a problem here. I don't know if it's because i'm using the latest driver from Nvidia
or if is because i'm using the latest version of windows 10, Windows 10 pro creators edition.

it's showing this error: http://imgur.com/a/xkFbs
i've tested all the miners you can think . the only one working right now is the eqm_V1.0.4cWin64


can someone please help me ?

obs: Yes i've checked my .bat file they're ok with the pools , and yes i did open the ports in the modem and router and shutdown the windows firewall and any windows antivirus.
and any antivirus at all.

I really don't know what to do.

Can you post your .bat file contents?

Yeah sure. here:http://imgur.com/a/IpnQY

I'm new to mining
Using GTX 1080Ti and I'm getting 750sol/s using EWBF's CUDA Zcash miner Version 0.3.3b.
Comparing with Nicehash excavator which gets only 700sol/s
My OC settings are:
TDP: 118%
Core Clock:+150
Memory Clock:+650
Temp: ~ 71C
Aggressive fan curve

Note: I have no power cost that's why I'm trying to get maximum speed.
