 Okay simple :

 I have  290 in ebay ebucks
 I have   250 in Amazon gift cards
 I have  100 in best buy credits.

I have an empty mobo  a z170  

with :

 intel i7 6700t
 windows 7  ultimate
 a 1tb ssd
 an evga 750 p2

two slots no risers
two risers

this rig worked well mining with 4 cards -----Windows 7
this rig worked well mining with 4 cards ----- smOS

So I can  get 3 nvidia cards  using my monies for ebay, amazon, best buy.

I do not want  anything but 1080 8gb or 1080 ti 11gb  I will mine zec

Please let me know if you have  a 1080 8gb  what  is the zec hash rate and power use.
Please let me know if you have  a 1080 ti 11 gb   what is the zec hash rate and power use.

Price does not matter  the 1080 ti 11gb costs more  but does it hash a lot higher then the 1080?

I only will have a 3 card rig  so highest hash  is most important  but of course if 1080 ti  is marginal  maybe 1080 is better.



I am not allowed to do a give away thread the rules state this in alt coins.

So I won't give a prize away for the best ideas.

No prizes ???

Would you sell me something if I have a good idea ;)

You have  a Best Buy  credit for 100 usd?

Just buy a nvidia 1080 from them  test it and return it.

Not a good idea at all.

Sleazy in fact.

I am looking for  people that are running nvidia for zec to chime in.

I want a top of the line card  which is the 1080 ti or the 1080

this is the Msi gtx 1080 8gb  new

A bit of data here to get you started - http://cryptomining-blog.com/tag/gtx-1080-ti-zec-efficiency/ (http://cryptomining-blog.com/tag/gtx-1080-ti-zec-efficiency/)

So the 1080 ti gives around 560 to 580

On efficiency settings.

Since I want a one or two card  or three card rig this is helpful.

Thanks

It's a baseline and just a starting piece of data that you might of found interesting.

Here's a video of an overclocked MSI 1080ti pulling ~760

This is a still from the video showing the clocks etc. - https://i.imgur.com/EjJGn2H.png (https://i.imgur.com/EjJGn2H.png)

a 1070 is better than a 1080 on cost/watt/hash ratio, why you choose the 1080? for density?

Good luck!

the rig will be 2 or 3 cards when done so density is important.

I am assembling a 1080 rig...will post info here about my findings

Thanks  I am debating to buy this one now


https://www.newegg.com/Product/Product.aspx?Item=N82E16814137069

then add this one

https://www.newegg.com/Product/Product.aspx?Item=N82E16814137113

if i can suggest you one brand, buy palit super jet stream, they are the best one, fabulous cooling and very silent, also hash faster than other with same setting(core clock go higher), thanks to an additional 10watt

unfortunately they cost a little more than the average

I know you're looking for more specific information as far as specific brand an oc settings of each 1080 or 1080ti card but Nichhash has a nice little calculator with generic cards and numbers.

https://www.nicehash.com/?p=calc

link please

if that 1080ti is already here in my country i would buy it....the 1080ti founders here is more expensive than that MSI 1080 ti (all 1080ti's here are still founders edition.)

I'm going for Zotac 1080 amp extreme. my judgement is based from that card having better (huge) cooler and higher clocks.

also gonna try for ASUS ROG STRIX-GTX1080-A8G-GAMING..(it is on its way thru shipping, just bought one)

manufacturers have different 1080s and they have different clocks.

after building a 1080 rig, if i'm satisfied with nvidia I'll build another rig for 1080 ti..

i think if you can go for 1080ti instead of 1080 rig..they are both GDDRX5 and the margin of performance between 1080 and 1080ti justifies the price(huge enough)....unlike the 390 and 390x price back then.

I have  these two on notify:

2 of these cards  should get me 1200 hash  on moderate settings

4 rx 480's  8gb  do 1200 hash  which is  4 slots vs 2

price is about 1500 nvidia  vs 1000 amd


power is about 400 nvidia vs   600 amd  not sure about this figure

1080 ti founders can hit 700 plus hash(i think i read it in 1080 vs 1080ti thread), these 1080 ti have higher clocks so at moderate settings, maybe it stays at 700 hash at least..that would be 1400 hash for 2..power and space wise, i think it is a win win

found a 1080 ti here...gigabyte aorus 1080 ti extreme edition which is about $120 more expensive than the 1080 ti's you mentioned...I might try one.

I purchased this one today


https://www.superbiiz.com/detail.php?name=ZT-G1080TF


cost me 720  and I get a very small discount of 14 so 706 net.

If I down clock  a one card rig at the wall should be 200 watts or less  doing 600 hash.

I have 16 rx 480's  doing about 4500 hash and about 2250 watts

and 2 rx 480's in 1 rig at the solar array

so   3 h to 1 watt =  nvidia
and 2 h to 1 watt = amd

I won't go all nvidia  but I think adding two two card rigs is a no brainer


You need to understand  I have 7 mobos running

I have 2 idle mobos fully ready.

Most people are not going  to build a two card rig from scratch.  I am building not building 2 card rigs

I had 11 four card rigs  I sold off all my rx 470's  leaving me with 18 rx 480 8gb cards using 8 rigs  and 3 empty mobos  ready for cards.

Actually I also think that it's about time to run Nvidia gpu in the daily usage rig, I have a farm with 41 RX gpu and another one with 17 GPU.
My daily rig at home running Dual RX480 all GPUs already ROI'd so it is not bad to test the other camp, not sure if I should do dual 1070 or single 1080.

go big  get the 1080 ti ;D


over 700h  when pushed
https://www.youtube.com/watch?v=yGXZDQYEN_w

Interesting ... I was thinking I have enough RX470 cards ... and maybe time for a little Nvidia mining.

They're quite a price, but also have good resale value, will be interested to see what you get out of it when it's up and running.

I love the idea of having that top dog inside my gaming rig especially since it is paying for it self so I can justify the price, however I can't justify spending big box for reference cooling, in a week or two there will be better offerings with 30-50$ more

then you should wait  as the 1080 ti  can do well over 700 h  

or on a low clock 600 and 200 watts.

I do have the

msi red led on auto notify---------  I like the rx 480 versions of it. I have 9
asus strix 3 fan on auto notify---- I like the rx 480 version of  it.  I have 6


I have 2 empty boards  waiting for cards.  If I were to get 5 1080 ti's  they would be close to 3500h

You mean those Red LEDs ?

No Sir, i dont know them . I have 5 rigs of 7 GPUs RX480 Gaming X , Best RX GPU . I have had 40 Nitro's 470 Upgraded to 480 MSI X. Better than 480 Nitro+ , better than RX480 Devil , and better than Strix and XFX.

Try to Hunt Evga GPUs , Best customer support and RMA service .

Personally i am limited to Amazon since it is the only store that ships to Egypt and pay all the customs and tax and in advance and deliver to your door step without headache .
Currently amazon options = none .

got my ASUS ROG STRIX-GTX1080-A8G-GAMING

OC to 2000 core and 5000 ram...getting only ~560 sols, driver 375.95, EWBF's CUDA Zcash miner 0.3.3b

zotac 1080 AMP extreme is coming by tomorrow.

I was expecting ~600 sols..

still looking for best drivers and settings, tweaks..

maybe that zotac will be my last 1080...will try 1080ti ~700+ sols is far from ~560 sols

yeah the 1080 ti  seems to be a lot better


11/8 = 1.375   x 560 = 770

the max  I have seen for a 1080 ti was 746 on the youtube link.

looks like it is simply a case of more ram  11 gb for the the 1080ti  vs 8gb for the 1080

I am going to slowly add up to four cards  over the next 2 months or so.

playing with asus OC..i was able to see instances of ~590-600 sols but stability has not been tested yet...

zotac amp extreme has a higher factory clock and bigger cooler...might get stable at 600 sols minimum.

anyway it's nice trying nvidia and seeing huge hashes for a single card :D.... excited to try 1080 ti..

we are at the same phase..will add slowly 1080 ti in 2 months..1080 ti's are quite expensive (that makes the upgrade a bit slow)

seems too low hashes for 1080 ti (640 sols?)...i think i may get the my 1080 here stable at ~590-600 sols

using EWBF here, not NiceHash Excavator

I think this is the founder edition and no oc..

Some advice on Zec. The cap is small and nvidia could pump the coin easy to sell the 1080ti.

So buying some Zec could be wise



Yeah and it is about max hash per. Watt

So trying to find max hash was not what they were trying to do.

Still 600 h at 200 watts is very good.

Also only one slot.

My pandaminer would do around 2200 to 2300 using 1100 watts.

Three of these should do about 2000 h at 700 watts

Price would be lower the the older b1 pandaminer

Newbie question - but why ZEC only?

nvidia  whales on zec  far better then amd

more hash less power.


at best amd is 2 h per 1 watt

nvidia is 3 h per watt

or
 .500 watts a h for amd     doing zec
 .333 watts a h for nvidia  doing zec

it is a clearcut winner  for zec.

found a deal on a zotac 1080


http://www.ebay.com/itm/381941454927?

it is 489 newegg is the eBay seller

the same card on newegg is  529


https://www.newegg.com/Product/Product.aspx?Item=N82E16814500414

I paid a lot less as I had 265 in ebucks  so I got a 1080 for around 255 out of pocket as I paid 34 in tax


this is the shortest 1080 card on the market.

I think I will be able to squeeze 3 cards on one of my biostar z170's

I now have a zotac 1080 ti and a zotac 1080  on order

so at this point the 1080 ti and the 1080 were about 985 out of pocket.

in theory i will do about 1100-1200 h  and maybe 375-425 watts

Gigabyte 1080 GV-N1080TTOC-8GD for $419 on ebay
http://www.ebay.com/itm/291974688954 (http://www.ebay.com/itm/291974688954)

nice price

planned in buying that zotac 1080 mini but backed out because I've seen a youtube video comparing it to galax HOF, temps of that zotac mini is ~20c more

will wait for your hashrate on your zotac mini 1080 card...will the temp get better with under volting, down clocking and still get good hashrates.

So  Phil  you have those  6 slot biostar rigs correct?


You could do slot  1 and slot 4 and slot 6.

A full sized  blower style  1080 ti  slot one

A full sized blower style   1080 ti slot four


The short  style              1080  slot six

that would let you run  fairly cool  and riser free with a small sized build.

Maybe 700 + 700 + 600 = 2000 h for zec

we will see how this works out.

@ theyankeeswin


yeah

  slot 1------     slot 2------      slot 3 -----    slot 4-----   slot 5 ----- slot 6

1080ti ________empty______empty _____1080ti ____empty ____ mini 1080


this is the plan.

I have a psu and a booster mobo ready for the cards.

I have one 1080 on order
I have one 1080 ti on order
I don't need the second  1080 ti to see if this will work.

If I put the 1080 ti in slot 4
and the mini 1080 in slot six  and it gets too hot  I know it won't work.


my zotac 1080 ti is  10.50 inches long

Max GPU Length

Card Dimensions (L x H)

the mini is  8.31 inches

I believe this will allow full air  for the longer 1080ti 

so goal would be 610 + 610 + 480 = 1700 at 540-600 watts
look at the z170 from biostar below

https://i.imgur.com/1bEAshu.png

for me I will go for biggest and baddest card in the lowest pcie slot, because there is nothing below that card to hinder anything.

Newegg has this in stock


https://www.newegg.com/Product/Product.aspx?Item=N82E16814125954



So I now have these 3 cards on order

https://www.newegg.com/Product/Product.aspx?Item=N82E16814125954    Aorus 1080 ti             net cost    760  taxes

https://www.newegg.com/Product/Product.aspx?Item=N82E16814500414   Zotac 1080 mini          net cost    260  on ebay with ebucks

https://www.superbiiz.com/detail.php?name=ZT-G1080TF                           Zotac 1080 ti              net cost   706  after a 2 %  discount.


______________________________________________________________________________ Total =  1726


I am hoping  for 1700h  at  545 watts

this would be  around  15 usd a day  and use 14 k-watts a day  my summer rates are nuts  once I adjust for cooling cost  I push  19 cents.  so that is 2.80 a day

15.00  -2.80 = 12.20 a day   profit with 19-20 cent power will be possible  that is a 150  day pay back

running my 1080 zotac amp extreme

both my asus and zotac 1080 appears to be stable ~570+ sols  with OC

the zotac amp extreme is massive it is bigger than my sapphire and MSI R9 390's, it's so heavy that it tends to tilt and lift its other side from the pcie socket, i zip tied it...found another use for my nut and screws lol

https://s7.postimg.org/ok5d6cf6j/IMAG0066.jpg

I have enough of 1080's

1080 ti massive hashrate for a single card is irresistible

I think zotac offers another 1 year extension for manufacturer warranty or more if you register your GPU, you might want to look into it..more years the better, specially when buying an expensive card  ;)

funny my mini sized zotac 1080 just came in

Yeah me too  here are some photos.
I opened garage door  and due to cool weather the room is only 80f

600 watts  this means I will need to get a bigger psu then a 750 watter.
as  the 600 watts is with a 72% power setting
it reads 759 watts at 100%  that it too much so  I will switch out psu later today

That Aorus does look big ;D

I noticed that  ZEC  is moving to .058 btc from .050 btc

Maybe you are right and Nvidia bumped it up a bit all the 1080 ti cards sold out.

http://coinmarketcap.com/

It went from 12 to 11th place.

Just like you said  it is only 72 million net worth  and Nvidia is worth more then 30 billion  they can bump up ZEC anytime they want to.

Hey guys,
I got 5 rx 480s (and one 1070), 480's sweet spot is 1200 mhz base and 2250 mem clock (it doesn't go higher), they do around 300-300 sol/s per card.
Yet my 1070 does 460 sol/s, so I'm gonna make another rig with 1070's.

I'm looking for a maker which doesn't have warranty void shit if thermal paste is changed (msi has that for example),
so I ran into 1070 mini http://www.gigabyte.com/Graphics-Card/GV-N1070IXOC-8GD#kf
I can get it pretty cheap, my question is - does it perform as well as the "normal" 1070?
Does it overheat? I want to change the thermal paste cause some tests show -5 to -10 celsius and +100 on clock speed if good paste is used.

What do you guys think?

Back side image:
https://content.hwigroup.net/images/products_xl/355405/2/gigabyte-geforce-gtx-1070-mini-itx-8gb.jpg

I've seen cards from msi and asus with warranty sticker on screws, so changing thermal paste voids warranty..I don't know about gigabyte..

I noticed Zotac don't have those..so I'm going for Zotac..waiting for 1080 ti amp extreme, my mining room is getting hotter so I'm investing in space (higher hashrate per card=1080ti) and bigger cooler (extreme edition)...basically I'm paying more for density and cooling..

TIP: to remove screw with a sticker, you have to use a vise grip (smaller nose to avoid hitting stuff when you turn it) on the screw but cover it a paper towel or a fine cloth.....I'm successful at MSI cards for 3 times already  ;)

Yeah 1070s are nice. But the better 1080 ti's  like the Aorus do 700h in Thier sleep.

If I could get six Aorus 1080 ti's at the right price I would buy them.

They would fit on my z170 mobos easy.

I could do two on each mobo do 1450h per mobo.

Around 450 watts per mobo.

Haha, great tip! I'll try it out ;)

@philipma1957 - yes, I agree, but I think 1070 has a better ROI, especially if you can get one for $350.
It can do 460 sol/s at a sweetspot, and use like 140W.
Cheapest 1080 ti I can find in EU is around $730 without shipping, and it does around 630 sol/s on ZEC while using 250W?

So, how about my 1070 mini question?
I'd get 6 of them, strictly for ZEC, good idea?

well if you control heat by setting at 65-75 power settings why not.

Remember in my case I have a lot of amd cards if all nvidia coins drop.

So I am hedged. 

 and the  vise grips trick can work. 

@phillipma1957


Is it possible to mix a rig with amd and nvidia?  I'm rather impressed by the speed/watt ratio of the nvidia. I may try one or two out soon. I just bought 12 480's to run with the biostars. But I have some pc's with a couple unused ports. If they are possible to mix I just may purchase a couple of these ti's. Do you or anyone have any exp with mixing and stability of the rig upon doing so. TIA

Edit. Also I'm noob when it comes to nvidia. Can these been ran at full speed thru a riser?

2nd edit. I see now you have it connected via riser. (Overlooked that first time thru your photos). I assume with them being below 512 bit data transfer i.e. r9390x it would work the same thru riser.

You can mix a rig, but the process I went through was annoying and you have to install both sets of drivers.

Thanks for the feedback. So no real tricks or hacks to make them work? Are there certain nvidia drivers that work best with mining software?  I.e. 16.12.2 work best for Polaris cards on claymore. Anything like that with nvidia.

I got a lot  info from this thread


https://bitcointalk.org/index.php?topic=1707546.0


I use drivers 378.78 

I hardly know anything  in the world of nvidia

but  I am getting 1850  h for zec  and using 616 watts     at the kill-a-watt meter.   and I know that is my hot meter  my other meter would read 580 or so.

This rig has amd drivers loaded  I could see if I can add a rx 480 to it later in the week.

I would be curious to see If I can run eth with the rx 480 and zec with the nvidia's

I am using 1 riser  for the 1080 zotac mini  the two 1080 ti are in full slots.

hahaha, the company produces consumption measuring device and calls it "kill-a-watt"? :D Golden!

On topic - that is a really nice hashrate. From 5x480s I get 1530 hash, while using 800W (it's the sweetspot),
Nvidia blows AMD out of the water with zec.

Anyways, I read a lot online about the mini cards, gamers and "casual" users hate them, they say they throttle more easily,
their fan runs on higher RPM etc etc... so I'm back to square 1, I'm thinking about getting the full size ones, price is the same...

Thanks for the info.  Going to be looking forward to building up a rig with nvidia just for sh%#s and giggles :) gonna have to work on getting the best price for the cards.  Ive got a load of shirts to print over the next few days then ill have more time to look into it.   Phil would you be interested in a few of those cases i have to put your rigs in for the summer? (https://bitcointalk.org/index.php?topic=1859550.0) I can imagine that room be getting rather hot when outside temps start getting up there.  I dont want anything for them.. just cover ship cost.. Ill gut them to reduce weight leaving you with the parts i kept to build it.  If you want the ras pi's you can have them as well.  Ive got way to many of those darn things.  The a1 weigh about 40-50 lbs a pc loaded.  Im building my second one with the other biostar mobo i have.  Should be completed today.  temps got to 80 f yesterday and the one i built in that thread ran at 60 % fan top heat on card was 55c.  Those that are in my milk crates ran upwards of 72c at 80% fan.  Big difference!..  Let me know we can work something out.  As always appreciate your info.  Very valuable.  Thanks again

BR

okay  just checked  the cases. 

I need to do a few things, before I say yes to two cases.

Please remind me near April 28th.

 I should know  what I am doing with the move of gear to the solar array.

.

No problem. I'll get them gutted in next couple days and give ya an idea what it will weigh so we can figure shipping. Don't worry about paying shipping ahead of time. I'll cover it till ya get them. I know your good for it.

BR

 As opposed to my 1070s at about half the cost of a 1080 ti and about $100ish less than the 1080 that manage over 400 on all of them (abet with VERY MILD overclocking - stock would probably be 380-400 range though, and perhaps 350ish at "most efficient" settings).

 I do not have a rig with Nvidia coexisting with RX series AMD, but quite a few of my rigs have 1070(s) coexisting with a wide range of older AMD APU/GPU cards (HD 7xxx series or A10 7860/7890).

 My go-to cards at this point are Gigabyte - the 2-fan full-size cards https://www.newegg.com/Product/Product.aspx?Item=N82E16814125875, and their micro-ATX very short model with the single fan.

 The EVGA cards I have work fine too, but don't seem to run QUITE as fast.

I've got a 1060 6GB humming along at 320+ and hoping to grab a couple of 1080ti's shortly.

Do you guys mine directly to ZEC or just use nicehash and have it converted to BTC?

for now nicehash to btc

Brand and power at the wall please?

To be honest the performance on your RX 480 isn't that great. I do 1470 h/s on 600 W (At the wall) with 5x 480. And my bioses are not even optimized for zec mining !

So what i'm concluding from this experiment is that 1080 ti are very efficient (620h/s for 180W, 3.4 h/W), but they are around 3x the price of modded RX 480 (300 h/s for 120W 2.5h/W) or a modded R9 Fury (~450 h/s for 200W, 2.25H/w ).
So we got 30% increase in efficiency for a price multiplied by 3, that doesn't seem like the sickest thing after thinking about it.
As far as I understand the problem with nvidia is that we don't have a lot of control over voltage and memory timings, so we can't really exploit the cards power to a 100%, also the miner's are maybe not yet fully optimized.
Meanwhile with AMD cards almost everything is tweakable enabling miners to optimize their card for the sole purpose of mining. Just look at the R9 fury that is built on 28nm and achieving almost the same efficiency as a card built on 14nm !

Given these i'm pretty sure vega will blow the 1080 ti out of the water on zec mining once we unleash our modding community. I'm sure they are already fully prepared.

well .. I get my nvidia gpus to 3.6 sol per watt easily .. no bios modding (warranty issues) etc
since power is expensive here I´d rather take gpus with a rate of 3.6 than double the hashcount but only 2.5 per watt

Well it also means the ROI is slower, but you are right, it depends on your personal constraints (electricity rate/space available/heat dissipation). Also keep in mind that nvidia cards can only mine equihash at this efficiency, right now.

Also phil did you manage to mine with AMD and Nvidia cards on the same mobo ? It  should work but you never know :P

yeah  but  You need a better cpu  not a cheap celeron.

In my case summer mining  with  amd is a no go.



 I have never seen a five card  amd giving 1500 h at 600 watts at the wall

but  I have seen  a four card amd giving  1210 h at 570 watts at the wall.




I can do  1800 h at 570 watts at the wall with the 1080 ti (3 pieces)

So I added about 600 h for no  watt cost.

and here is the lowest price yet for a 1080 ti


http://galaxstore.net/GALAX-GeForce-GTX-1080-TI-Founders-Edition_p_123.html


659 + 15 to ship to NJ = 675

Why is that?

well when I did it with the celeron  the gear got laggy as I ran  2 mining  programs.

EWBF_3.3b for nvidia zcash

Claymore for amd zcash

when I did it on the i7 6700t  no lagginess.

Oh wow you americans and your sick gpu deals...in france the custom 1080 ti models barely arrived and the best price i've seen so far is 750€ on founders edition, usually they are around 800€. Of course if you got deals like that it's a no brainer :P

I'm running 5 rx 480 @ 730W at the wall on ETH, so yeah I run around 600W on ZEC, maybe 630W because I measured when the miner just started and the fans weren't running at cruise speed yet. That's the power of -100mv on core and modified timings...
I also saw someone that managed to get 500 h/s with custom memory timings on a R9 fury (HBM) but these guys don't give you the bios for free.

Modding your card is a personal decision, indeed if you don't mod your AMD cards (that looks like it's your case), you better buy nvidias. But for me that enjoy tweaking, optimizing and sending cards to RMA, the buying is not that obvious with vega coming along in june...basically I need really good deals

Yeah  but France has good health insurance ,nice food,nice wine and in general a  fairly good country to be in.

We Americans get bargains on electronics,  but if you get sick  it is very expensive.

My wife and I spend just about 10k each year on health insurance and health care. We are 60 and 61  our health is decent not a lot wrong with us.

 My neighbor  Has a wife and 3 kids.  He spends 28k on health insurance premiums and health care. His kids have some illnesses that cost $$$

Hey Phil, what TI models already arrived in hand.
I have pre ordered 3 cards and not sure which order I should keep.
Founder edition 756 Euro with shipping date 19 April
MSI armor 773 euro
MSI gaming X 822 Euro
Both MSI to be shipped on May 13
We are talking about at least 20 days wasted if mining between the founder and the other options, some founder should be calculated at 650 Euro.
Armor have no backplate ( Huge Down)
Both MSI won't fit inside my itx Case (thermaltake core v1) so I will have the change the case.
Do you agree that founder is the best way to go?
Only choice better than founder and fits inside the case is  the Evga SC2 and yet it is no where to be found

Phil inspired me to get a MSI 1080 GTX for my daily driver. Just set it up with nicehash miner and getting 406 H/S.

Can I get much more out of it if I read up on how to tweak it??

You can do better than that :)

Grab EWBF's miner from here - https://drive.google.com/open?id=0B9EPp8NdigFianNlcUh0YWFhOVE

Then run it with the following command: miner --server equihash.usa.nicehash.com --pec --user YOURBITCOINADDRESS --pass x --port 3357
You might want to change servers to whatever is closest. Check on nicehash's website for pool addresses.

Then try MSI afterburner to adjust clocks and memory speed if you want to fine tune things :)

my 1080  using ewbf and msi afterburner does 505h

power          75%
core         +150
memory   + 350
fan manual   75%

i point ewbf at nicehash

mine zec and auto convert to btc

Wow 28k on health insurance  :o That's the annual salary of a junior engineer ! How many 1080 ti is that ?  It's true frenchies tend to forget how they got it easy ! We always complain but the life is pretty sweet here. As my father says "I've visited many countries and the only place I'm happy is France". I've travelled a bit myself and I get homesick pretty quickly if I don't have my cheese and my wine  :D

I am Italian/Norwegian American

But was in the USN  for  5 years so I have been to a lot of countries.

   Italy, France  food and wine = priority.
 So they were the two  nicest places for me.
Maybe Mauritius  was in third place. A beautiful Island paradise in the Indian Ocean

Thanks! This takes me from 407 to 470. Will have a play with Afterburner now.

Finally had time to tweak my two Geforce 1080ti FE cards for ZEC mining (EWBF 0.3.3b), the best I've come up with is:

Total rig power draw: 346W, total hash rate: 1272 Sol/s (3.67 Sols/W)

GPU0: 148w @ 641 sols (4.33 Sols/W)
GPU1: 151W @ 631 sols (4.17 Sols/W)

Afterburner: 60% Power, +240 Core Clock, -300 Memory Clock, Fans @ 60%, GPU Temps 56°C and 47°C

Not sure if I can do better ... but run out of 'tweaking' time ... things to do.

Here are my settings for a MSI 1080GTX 8GB


Thanks for the TI settings Devon.
I managed to find an EVGA 1080 Ti 11gb on sale for USD758 which is pretty cheap in my Country. Should have that up and running by Thursday :)

 Mine were all Pacific - I have fond memories of Thailand and Hong Kong/Kowloon (sp?), mixed of the Phillipines (Subic Bay, Olongopo, and Subic City) and Japan, don't really remember the stop at Korea, and UNfond memories of the shipwreck that left us unable to make it to Singapore and the I/O planned part of our WestPac tour (I was looking forward to Australia, but NOT to Diego Garcia), instead we limped back TO Subic for patches so we could limp to Japan (Yokosuka) for temp repairs then a few months tooling around the Pacific 'till later back to Japan for a complete bow replacement.


 Ranger and the Liberia Fortune are no longer in the Guiness Book for the largest collision at sea, but we were there for a short while (got beat out when 2 of the 600,000 ton class oil tankers collided).

197 days at Diego Garica  .     You were on the Ranger  my cousin Peter  was there late 70's to early 80's  he was a Data Processing tech.  as was I on the USS Dixie Ad-14

 If it doesn't work, try one of the Gigabyte "ITX" 1070 cards in slot 6 - they're a good bit shorter than the Zotac, much less anything else.

https://www.newegg.com/Product/Product.aspx?Item=N82E16814125893


 I end up with cards at 2-5-7 on my 3-slot motherboards, so same effective spacing as you're using - and no cooling issues for the middle card as it has one fan completely unblocked even on the 2-fan Gigabyte or EVGA cards I have.

 If your cousin was a DT on Ranger in the '79-'80 timeframe, I probably knew him by sight if not by name, as we would both have been in OE division.
