Thanks Phil.

Decided to keep the cards. Added 4 to the daily rig and all 4 ticking over nicely on those oc settings. Quiet as a mouse.

Rig wise I've ordered a pair of p2 1200w and emailed evga for additional 6+2/6 cables. Issues solved. The I'd for the help/advice.

Yeah, no issue. Did consider the stock zotac but its a blower which I assumed wouldn't be the best for cooling and noise.

yeah  2x jack 8 pin are not good  for your setup.

most of us don't max the cards  and the cards only go to 180 watts maxed

even these are nice

https://www.amazon.com/MSI-GTX-1070-TI-AERO/dp/B076QDSVB4/ref=sr_1_3?

set to 75% tdp and fans at 75%

they will do close to 500 sols at zec

with 180 core
660 memory

75% tdp and

75% fan.

if you use risers  give them a little extra room  say a 4 inch gap once installed

best way is use 1 pcie cable into the card and into the riser  with an extension like this

https://www.amazon.com/Cable-Matters-2-Pack-6-Pin-Extension/dp/B01DV1Z4EQ/ref=sr_1_8_sspa?


the dual cable powers the card and the riser.  and 1070 ti will be using around 125 watts for the one cable total.

that is why a single eight pin 1070 ti  card is better.

What's the rule of thumb for powering the Risers? Is sata a no go?

Might just split the lot into two 6 gpu rigs...

Ditch asrock h110 for x2 ga-z270p-d3
Evga 1600w on each.
Vga 1-6 with 6+2/6 to each gpu using included gpu 6 to 8 pin adaptors.
Vga 7-9 powering x6 risers using 8pin to dual 6 pin adapters.

Two. Amp, not amp extreme.

well the psu is a mismatch to those cards.

return the psu or return the cards

hint return the cards

2x 8pin = waste of money

many 1070 ti's  use 1 x  8 pin.

the entire idea of 1070 or 1070 ti is

one 8 pin jack.

as you now see.

no one should be mining large rigs of 9 cards with 2 jack eight pin 1070 ti's

can you return the cards?

can you get these

Looking for advice on psu setup.

Currently have 9 1070ti which use 2x8pin.

Originally was going to use an asrock h110.

Got a 2kw superflower psu in the daily which i had intended to use in the following config:

Psu has x9 8 pin plus cpu 8 pin. (Similar to evga 1600w)

6+2/6 to each gpu. Each /6 with the dual 6 to 8 pin included with the gpu.

All risers powered with sata. Risers are 6 pin with sata adapter.


Have been advised powering the risers with the included 6 pin to sata connectors is a big no no

Struggling to decide on best setup for powering the rig.

Splitting into two 6/6 rigs also an option.

Gpus are zotac amp.

If the inteded setup is not advised, what's the most cost efficient setup....

first off alt coins not here

next zotac amp with

two fans

or with three fans
