Title: >4 GTX 1070 Windows 10 Post by: moonpigman on June 24, 2017, 12:27:25 AM Hi,
Anyone been able to get 5 or 6 GTX 1070s to detect under windows? I've successfully got rigs with 6+ AMD GPUs but can't seem to get the NVIDIA cards to the same. Currently setup is: -G3950 celeron -8GB DDR4 -60GB SSD -4xMSI ARMOUR 8GB GTX 1070 -MSI Z270-A PRO MB -EVGA GQ 1000W Gold+ PSU As far as I know (correct if wrong), a 5th GPU should run on 1000W? I know 6 won't and next week I'll be dual running two x 750W PSUs to handle it but for test purposes I believe 5 1070s should run in 1000W at stock settings. I have tried enabling 4G in BIOS, PCI Gen 1 in BIOS Cannot seem to get the card to even show in device manager in Windows. Tried swapping Risers to new ones, power cables etc. How can I determine if this is a PSU issue vs other issue? EDIT: We tried a few more risers and cables and now it shows up so I think it was a dodgy couple risers. 4G Enabled and PCI Gen 1 on MSI mobo all 5 display in DevMgr and mine now Cheers Title: Re: >4 GTX 1070 Windows 10 Post by: Epicit on June 24, 2017, 01:00:37 AM I had kind of the same issue. 2 1080's 2 1050ti tried to add a 970 it just wouldn't keep it. I saw it randomly in device manger. This was with a 1000w and an 850 tried everything power wise no luck yet.

Solo mining ETH. 30.5 M/H per card. 784 watts from the wall. Title: Re: >4 GTX 1070 Windows 10 Post by: gctom on June 24, 2017, 09:29:47 AM Windows installed in uefi mode?
That did the tricks for me.

Solo mining ETH. 30.5 M/H per card. 784 watts from the wall. 30.5 MH/s per card with just 784 from the wall? :o) Can you maybe tell me your OC settings? When i pushed my card to 30.5 i was at 175W ;D |
