I'll be moving 3 of these cards to a new system this weekend -- sadly it'll be Win10 instead of Win7 it'll have a few factors different but I'm interested in seeing if it is better.

(also bumping old thread to get the spammers off the front page)

3 of the cards moved to a Win 10 machine; no boot delay :| Dare I upgrade my OS?

Different machine, different motherboard & BIOS?

At this point I've got 8 of the same make & model GTX 1070 in my cluster:

• 3 in a Asus P6T (Intel X58) Win7 machine that never had problems.
  
• 2 in a Asus P5Q-E (Intel P45) Win10 machine (taken from the original quad)
  
• 3 in a Gigabyte GA-990FXA-UD5 R5 (AMD 990FX) Win10 machine (the other two from the original quad)
  

In the problematic machine (Asus Rampage V Extreme) I've been running dual 980 Ti's (again) with no problems whatsoever.

The boot delay wasn't the only problem either; I'd get the occasional deadlock and it seemed like it was aggravating USB devices - my external sound card and webcam would sometimes need to be unplugged and replugged.

I've more or less given up trying to figure out why it doesn't work because I need this machine to be headache free for work; the 980 Ti's aren't very efficient but they're getting a good chunk of work done. I may be silly in the spring when Vega cards are out -- I was thinking of trying a pair and if they are okay filling in two more. 40 PCIe lanes and 8 real cores are a shame to waste on just 2 cards.

I feel you shaggie.

I have the same board and 4 EVGA 1070s in mine. It takes around 5 minutes for it to boot up. I get the impression that is it cycling as it gets ready to complete the boot. What I mean is this. I have in my preferences to turn off the illumination of the cards on startup. So once I press the power up button it will begin with all the GPUs lit. After about 2 minutes, 1 GPU illumination will go off...then about 1 minute later another and so on.. It will do this for all 4 cards. Then about 2 minutes after the last card has turned off the illumination, I will get the log in screen. So it looks like it is going thru some boot up recycling for each card before finally moving on to the login screen. Just thought I would share that with you.

That's super interesting that you have similar problems with that board -- thanks for sharing!
