I have exactly the same behavior at one of my 1080ti rig... I still don't know why 3 cards from 6 are with the LEDs blinking white (I have 1080ti Aorus), although the cards are mining with no issue. The rig has 2 PSU and 2 cards connected to one + 1 card connected to the second PSU shows this behavior.... Does your cards are mining?

LOL Vosk (love your doge, what his name again?)

... I am no expert but for the multi GPUs 12/13/19 slots -- you will have PSU headaches esp for higher end cards (dual 8pins)

The rule of thumb is as follows:

The risers need to be powered and initalized by the mobo first.

Lastly, the GPUs gets power and sees all risers synch with mobo.

Therefore, your risers and mobo, need to be on 1 x PSU.

And your all your GPUs with the Delta.

I doubt it if you can go up to 12/13/19 x 1080tis -- unless you can follow the guide above and still have enough ports on the Deltas.

I think 8 x 1080ti on a riserless board like what Phil is doing is the gold standard now for perfect - highest density, highest hash.

Another solution that worked for me was a special cable that powers the GPU and riser at the same time (1 single cable) -- but that was on RX470/480 or 1070s -- ie. single 6/8pin). For higher end cards like 1080ti -- that will be more complicated.... you will run out of ports in no time on the Deltas.

Phil, sootha, Storx may have some creative ideas - anyone?

Since my ATX PSU is used only for the mobo, I use 2 x cables to power each molex just to be on safe side. I dont trust these 4pins molex.

My PCIE cables are custom made to power the RX470 and riser together - the RX470 rom modded so that single cable will not exceed threshold.

I have the H110 -- you need to power both molex on the mobo to make it work stable.

I can get away without the molex powered if I run XMR but once you mine ZEC or ETH, you need the extra juice and both 4-pin molex needs to be powered.

With all 13 x GPUs  (GA and Sapphire RX 470s)

Scenario 1: XMR - 1 Delta 2400w and PICO kit (consuming 1000-1200watts)

Scenario 2: ZEC and ETH - 1 Delta for all the risers and GPUs, and 1 x ATX PSU to power mobo and the 2 damn 4-pin molex (1600-1700watts)

I got a really good price on the 1800x   329  which made it worth buying.

otherwise the 1700x if you are lucky can be as low as 279

Currently mining xmr or aeon using my 1700x and 1600x. They are good. no need 1800x.

I agree with you on getting out of x11

What do you reckon dash difficulty will be after all those miners you mentioned are shipped?

 RX 470 Sapphire mining cards when you can get them at 270 ballpark, running ETH.
 1070/1080/1080ti are a very close tossup running ZEC or ZEN or LYRAv2 - and this calculation is close enough to change daily or even hourly.

 The "basket of profitable mining coins" right now is a large one.

 Not sure yet where the GTX 1070ti is going to fall in the list - from the specs I expect it to be a better ETH performer than the 1070 and possibly the 1080ti but a hair worse on ZEC than the 1080, abet at enough lower of a price point to make it competative.

 I'm going to be putting one on preorder later today, as part of my "next card expansion" plans.

 Still debating if I want to get one Vega 56 (now that the pricing is finally dropping some) to play with - I think it might have a niche in my BOINC/Moo Wrapper/D.Net/GRC effort as it should have similar keyrate to a 1080ti at a LOT lower price point but I am worried a bit about the power consumption.

 I like the Zotac Mini 1070, but they're pushing the form factor quite a bit for cooling on the 1080 version and I don't even want to THINK about how hot the 1080ti version has to run.
 
1070 prices have been dropping for a while now - they're ALMOST back down to Febuary levels and availability has been good for a few weeks.

my tired eyes do not see as well as they did when I was your age
slow shipping.
Slow response on rma's

 --- biostar took more then 90 days
--- gigabyte is also very slow.

evga is a pleasure on an rma.
intel is also really good.
frankly  gpus are kind of fun more then anything else.


asics suck.

slow to ship
break often
seller is almost always in china
rma's really suck.

For mining it looks like the 1070 Ti is pretty meh. Same ETH rate, little bit better core rate.. probably best to still go with 1080 Tis

What state are you in?
I'm paying 20.0907 AUD per kWh through powershop in Victoria.
