No, I dont want to run them at 100% Phil.  Btw i did small benchmark on my 1080ti Aorus on digibyte-skein :

https://gyazo.com/c568b5b6aae68b51bf4b5c3ae780e0f6

X axis is power limit
At 70% power limit we're losing only 9% hashrate

I will buy risers with PCIe power connectors.
Thanks a lot guys!

Powered risers are a must so that any extra juice required by GPU will come from PSU and not the motherboard. You can see many horror stories online when power overdraw happens esp older cards that has high tdp.... fried motherboards, damaged slots and GPUs are the results... or worse case fire etc

Back in the Litecoin days circa 2014... you have mobos like Asrock H81 Pro BTC that needs a powered molex to the motherboard -- because back in those days .... risers were flimsy ribbon type and some of them don't have power or unreliable hazardous power connectors. If you use H81s today, you dont need to use that onboard molex power as long as your risers are powered by PSU.

The best risers that I have so far are those provide by yslsyung, v6 risers with PCIE power connectors and beefy shielded USB3 cables. I previously used v3 risers with 4-pin molex to SATA power connectors -- although still ok to use, I prefer the PCIE powered ones for best performance and standardize it with PICO and server PSU solution.

what do you plan to do with the gpus  run them at 100% tdp?

if you do it is not safe.  and you really should not run a six card build.

run a 4 card.


you do under stand that a 1080 ti  will pull 250 watts at 100%  and 175 watts at 70 %


6 x 250 = 1500 plus 100 for the entire rig = 1600  watts which will fail

6 x 175 = 1050  plus 100 for the entire rig = 1150  watts 0 worries.    my idea is good.

There is a sale at Newegg and one of my group member got hold of the following...

Given the circumstances of 1080ti going off the shelves like bats out of a cave, any decent 1080ti will do -- above reference specs at minimum for reasonable price ~ sub 800$ -- I suspect that given this model's huge size, medium clocks (vs Extreme version like Auros etc), Newegg will be keen to move these out so that they can stock better and smaller OC gaming versions..

Well a 1080ti is basically the same apart from various gaming OC solution by vendors that will make them go at higher clocks.

At this price, I don't mind medium performance 1080ti, set 4 of them up and hang them like smoked salmon powered by 1200w PSU will be worthy mining beast.

Just saw it jump 50Gh from when u posted this - guess folks got their UPS deliveries today lol

*** lol 11 min ago when I posted the 50Gh bounce it was 130 I think ... now it's at 180 and rising - looks like fluxing pretty hard now back down to 100Gh hah

What is the difference? They're both pci express adapters powered by molex to sata cable? Forgive me if i cant see something obvious. Atm running 2xti through these risers powered from molex cables from psu fwiw.

As for the psu and gpus, thanks a lot! I was afraid i cant simply use these 6 to 8 pin adapters because i have read they might not be able to suppoy enough power.

Edit: sorry i see now. These risers have pcie power slot. Are they a must?

no good  you must use the pcie ones

i will find a link


https://www.amazon.co.uk/Kyerivs-PCI-E-Powered-Adapter-Extension/dp/B06ZYCRX7B/ref=sr_1_1?

Hey.
Yes i bought these
https://www.amazon.co.uk/gp/aw/d/B01MG8XQDX/ref=mp_s_a_1_2?ie=UTF8&qid=1495846337&sr=8-2&pi=AC_SX236_SY340_QL65&keywords=pci+riser&dpPl=1&dpID=51M-U-7HepL&ref=plSrch

there are options give me some time to get links

you will be using 6 risers correct?

which risers?

you get 9 pcie cables

4 of them  are 8 pin   so that runs 1 card  and leaves you 2 empty 8 pin cables



5 of them are 8 + 6   so that runs 5 cards   huh? how? wtf?

https://www.amazon.com/Cable-Matters-2-Pack-6-Pin-Adapter/dp/B01DV1Z32Y/ref=sr_1_2?

so you now have all 8 pin jacks in the 6 gpus done

with 2 eight pin pcie cables  buy 2 of these

https://www.amazon.com/11-inch-PCI-Express-Female-Splitter-Sleeves/dp/B01LVZBJML/ref=sr_1_1?

and you have fully powered 6 cards and 4 risers.

leaving you with 2 riser that will use separate sata to pcie for power.

you must have risers that use pcie jack to do this.

And this is why my rigs are 3 or 4 cards not six.

Hey guys. Firstly thank you for your input, all these posts helped me a lot.

Im building a 1080ti rig (i want 6x).
I bought an EVGA 1600W P2 PSU. It has 9x vga power slots so i thought it will be allright but it turned out it has only 8pin->6 + (6+2) pin VGA cables. My Aorus 1080ti's have 2x8 pin slots so i dont have correct cable. In such case they advise just to use separate power cables from PSU to power each 8pin port, but this way i will be limited to 4 cards ( 2cablesx4cards=8 , and i have just 9 vga slots).

What are my options ? Return at least some Aoruses and replace them with Founders edition? (it has 6+8 pin port like my vga cable)? Buy some third party cables? Maybe use some sort of adapter?

Ah! I knew I forgot something. been so busy setting up all the new cards that I forgot i needed to grab your batch! So yeah running nemos not yours. I'll try yours out for sure when i get to my girls house!

Thanks a bunch

I was out for the whole day  just got home.

4 rigs running and 1 is crashed.

I did the entire set of rigs at 50% tdp  as a prep for summer mining.

11 amps dropped  to 8.5 amps and hash also dropped  by the same ratio for the most part.

I need to see which rig crashed.

 The only thing to worry about on the 1080ti are the rumours that NVidia might drop prices some on the 2xxx "refresh" when it shows up - but that appears to still be months off, you should make plenty to make up the difference by then even if you don't manage to pay off the 1080ti in that timeframe.


 It looks like I timed my last "rig parts" purchase near perfectly, as BTC started sliding some a few hours later.
 8-)

 (edit) and WOW has it slid a lot since I made that purchase.
 So nice to be psychic for once!

 Even if all cryptocoin drops 50% over the next month (edit - that's starting to look POSSIBLE, I was just doom and glooming when I originally posted that comment), most miners should STILL be way ahead on profitability over the last half of last year and the first couple months of this year - and those that didn't use the recent "surge" to finance expansion are just losing out (unless they're severely power-limited, in which case they should have been retiring older less-efficient ASIC and GPUs and liquidating them in favor of newer more-efficient ones).


 DGB profitability has been bouncing all over for the entire week-and-change I've been tracking it - way too small a total network hash on ALL of it's options, even a single mid-range miner like I am can have a noticeable effect on it.
 

 The AORUS cards are beasts - very high clocks, very high-end cooling for air-cool cards - if you can handle them being 2.5 cards wide and the needed spacing they look like the best option on the high-end (water-cooled stuff gets too expen$ive to be cost effective, with the POSSIBLE exception of those folks in hot+wet climates that can't use evap cooling to get the hot down to a tolerable level).


 IRS compliance being "binding" has been challenged in court a few times - with ZERO successes.

 At this point the applicable precedents are all "you WILL pay taxes or you WILL pay the penalties or you are a criminal".
 While precedent is not BINDING on a judge, it is a very rare case that a judge will rule AGAINST an existing precedent where there are ZERO contradictory precedent to work with and quite a few in favor of a particular interpretation.

Nemos batch or my batch?  My auto-batch swapps algos almost instantly;  as long as the PC can handle one instance of ccminer launching for each algo;  all at once....

Well... 9.6Gh of that yesterday was me and the new 1080ti's- and later tonight I'll be setting up another 4Gh at my girlfriends house ... hers are going to be only 1070's so maybe I'll point them to something else but I'm not sure yet.

Nemos miner I tried to just run the start bat but I get trouble connecting when it tries to switch algos, it sometimes searches for 5-10 minutes to finally catch a new algo which is kinda nuts.

DGB on yobit: -16%
AUR on yobit: +2.6%

Its down a tad;  plus another 20Gh just jumped on since last I checked yesterday....

There are some slumps;  but the good days are totally more than the bad...  You just see it faster because of the faster block times on this algo.

FYI: ZEC is -11.9%; so it seems all the whales are dumping alts to invest in BTC for the slump.... (guess)

Awesome thanks a ton!

For Skein currently it's not doing well for me - I'm on ZPool and for the past 12 hours it looks like it tanked for me - daily calculations on current earnings is only:

3.830636066 mBTC per 1 GH/s =
1 1080Ti @ 800 MH/s = 3.064508852mBTC or $6.96 @ current rate.... that's a pretty significant drop

So which 1080 ti do you guys recommend?

These would be my options:

Gigabyte AORUS GeForce GTX 1080 Ti Xtreme Edition, 11GB GDDR5X, 352 bit
Gigabyte AORUS GeForce GTX 1080 Ti, 11GB GDDR5X, 352 bit
MSI GTX 1080 TI GAMING X 11G, 11GB GDDRX5, 392-bit
MSI GTX 1080 TI ARMOR, 11GB GDDRX5, 392-bit
ASUS GeForce GTX 1080 Ti STRIX GAMING O11G 11GB DDR5X 352-bit
ASUS GeForce GTX 1080 Ti STRIX GAMING 11GB DDR5X 352-bit

Any thoughts appreciated. Thanks

I use afterburner on all rigs except one I use firestorm from zotac  which is like msi afterburner as that rig will not let afterburner work right and after a complete install of everything from start it still said f u to me. so I  Installed firestorm works about the same as afterburner.

So on a 3 1080 ti rig  I synch the 3 cards in afterburner


for skein

70%
150 core
0 memory
75% fan

for zec
70%
200 core
0 memory
75% fan

thats on all  of the 8 founders edition cards

on the 1 aorus  it has a higher core   so   I do 125 for skein and 150 for zec

I also have 4 msi aero  1080ti  the clocks are higher on core so I do 140 for skein and 160 for zec.

pdu question  the correct setup will let you power cycle  from anywhere in the world via an eth cord to the router.  and if you have smOS  and the mobos are set to power up when power is restore it is easy.

if you have 1080 ti's  no smos  I know the rigs will  power on via a pdu recycle you then need a scrypt to start it mining.


Since my summer rates kick in June 1 . I am doing a low power test today.

I set all cards to 50% vs 70%.

The Psu meter dropped from 11 amps to 8.5

So 2640 watts is now 2040 watts .

This is good as ac bill and mining bill will both drop

As will hash rate.

But heat will mange better

Sorry for confusion, I bad read the message.

Flminer asked for windows 8 question, and I thought it was about win 10.
So my link was about 8gpus on Win10.
Didn't expect to start a windows debate !
