Mixed GPU Rig Issues???

[dirtydeeds]

Hey Guys,
         I just started mining January and was able to piece together a few rigs.  The rigs that have all identical cards are running flawlessly for days. But, I have 2 that keep crashing after like 6 hours or so.

I am losing my mind!
 
I posted the below specs about 2 weeks ago in another thread and I think I posted in the wrong area because I didn't get to much of a response.

One guys said that I have bad risers......since then I have replaced the risers and updated the bios got shorter extension cords...But still these 2 rigs crash about every 6 hours. 

Any Ideas at all? 

Running them on SMOS with ewbf-0.3.4b mining zclassic

Both rigs use the following hardware:

GIGABYTE GA-Z270P-D3 LGA1151

Intel BX80662G4400 Pentium Processor G4400 3.3 GHz

Ballistix Sport LT 4GB Single DDR4 2400 MT/s (PC4-19200)

Lexar JumpDrive S75 64GB USB 3.0 Flash Drive

VICTONY GPU Riser Adapter

EVGA SuperNOVA 850 G2, 80+ GOLD 850W

Also 5 intake fans per rig on  open air cases.

Rig #1 uses the following cards:
4 x Gigabyte AORUS XTREME GeForce GTX 1060 6GB
2 x Gigabyte GeForce GTX 1060 Windforce OC 6GB

2 x EVGA GeForce GTX 1060 SC GAMING, ACX 2.0 (Single Fan), 6GB

options:

   --server us-east.zclassic.miningpoolhub.com --port 20575 --user dirtydeeds.$rigName --pass x

Not overclocked and still crashing after a few hours or less.  I am feeding 90volts to the 1060s and 100volts to the 1070s.

No more than 2 risers per sata cable.

PLEASE HELP!

Any suggestions?

have you tried 8gb ram for the mobo's? I use minimum of 8gb for all my rigs, which all mostly run dual channel ddr3 8gb, I think I have 1 rig that is doing single channel but that's because I goofed. I don't see any of the silly problems majority of noobs seem to experience, only thing ive had to experience so far is not enough power for the gpus and that's it

maybe try an ssd instead of a pendrive too, those were never made for what you are trying to use it for

This might be worth a try.

For some time now I have been running all my cards separately as individual miners rather than the whole rig (6 cards) as one miner, I am running 2 6 card rigs.

That way if it is one card causing the problem only that card shuts down and not the whole rig. This also highlights which card is causing the problem and it can then be investigated on it's own.

Just a thought to try..... I use ccminer so it is easy to set cards individually.....
