I havn't actually experienced that with zpool.  Using calculators and a conservative average hash rate I have always come out slightly more than I expected.

There was a few days a week or so ago when it went a bit screwy though.

I use a similar fan to what you are using directly at 2x 1080ti FE.  Because one of them was sucking warm air off the back of the other one it was getting 20C hotter.  After putting one of those fans blowing air in between them the hot one dropped 20C and the cold one dropped a small amount.  So overall I was able to drop their fan speeds.  Ideally I need a bigger gap between them.  They are blower style but I have them in an open air rig atm.

Yes direct DGB and no BTC converting. My first idea was a weekly exchange. But i bet on high value next month. Time will say if I make a big lose 
I mine on suprnova. Zpools exchange rate is worse then the real value. So even when you go DGB and exchange then you will make more.
Okay Thank you. Thats calm me a little bit down.
The noise of the Fans is no problem. Maybe the Fans will not live so long with 24/7 100% but then I take the warranty.
I bought 2 Noctua nf-a14 ippc 2000 and will crank them on the hottest card. Lets take a look if it helps.
Yes to Change the TDP is a way. Will try to modify the voltage curve to sqeeze the Rest out of it

Are you mining DGB also?  I have been buying a bit.  Looking at DGB on the market the price jumps around so much  BTC is generally stable/goes up apart from recently.  Can someone give me some insight on why mining the coin directly is better than say converting earnings directly to BTC (which is usually stable)  then buying whatever coins you want such as DGB only when the market dips as DGB espeically seems to dip and rise heavily in a 24 hour period.

Can you get more coins this way?  I assume you are mining Zpool  skein and getting paid out in DGB instead of BTC so the value of the mining is pretty much the same or are you doing it some other way?  On zpools it says you can get paid in other currencys at your own risk what does this mean hah!

I have personally directly mined eth and Zec and that was worth it.  But again they are pretty stable/mostly going up unlike DGB.

I'm mining and not converting - it's a risk we're willing to take - if it pays out it be be a nice doubling of mining earnings so we don't mind.

For lower TDP we're actually thinking of running at lower 50-60%tdp but that reduces earnings as well.

Let's say you're running 80A of cards - roughly 37 1080Tis

@75% we're roughly at 25 KH/s @ 80A
@50% we're roughly at 17 KH/s @ 57A

That's about a 3k loss so we'll be running everything at 75%

If we do the same 80A @ 50% TDP it would require 13 more cards and NET about 2k/mo more, but 13 1080Ti's would cost around 10k so 5mo ROI @ current rates for the increase in cards (not counting base of Rig so basically add another $125 per 1080Ti)

So you are not converting to BTC going directly to being paid in DGB?  I'm not too sure about that strategy .   I have dropped some BTC in DGB by buying it when the price dips heavily on the exchange.  Mining to BTC has paid off too while the price was down as it has gone up ALOT in the last 2 weeks so all that BTC mined previously is worth more now.

Time to buy a bit more DGB I think.

That temp is fine though I personally prefer to run under 60C but I think most aim for under 70C.  I dunno is maxing the fans is a good idea but if you can handle the sound it doesnt really use noticable extra power.  Best thing you could do is lower you TDP which will drop the heat alot.  You could go down to 60 and not really lose much unless you have free power.

It is winter here.  I run all my cards 60-75 TDP, and fan speed 50-65.  It keeps the temp down alot droping the TDP.   So in summer you should drop to 60% (some even go a bit lower) for the efficiency.  But it depends on how many cards you got because sometimes because of the return/power price it doesnt pay to be efficient it pays to get the best mining rate you can while still maintaining a good heat.  A  "Ghetto" fan would help.

Right now though the mining returns pretty much best to be around 60-70 compared to a few weeks ago I could crank it a bit more.

I've read 70's is fine.

disclaimer: I'm reckless

I have some cards that run @80c - which is pretty much every POS MSI Armor I have so I could care less about those - but they've been at 80-85 24/7 the past month - since they have 12mo warranty and I've got spare cards in case they go down All is well. Every good Jew always has multiple spares - I'm a good Jew

4 x 1080ti Full @ Skein DGB.
I hope the price rise next month.
Thats my bet 

But i have a question. The summer heat make actual some problems. The core is 65C @ 100% Fan and 85 % TDP.
I will try some Ghetto mod in the next days. But is this temp Okay?
Thank you very much

It doesn't like 65 core @ 100%  Can handle +50 @ 100% but I get more sol at +75 75% TPD.
Does not like +75 core 85%
Is fine on +70 80% TDP.  So I think +50 is pretty safe bet.

Thanks for the tips.

What is everyone mining right now.  I am doing pretty much just ZEC.   But I see mining ZCL, Hush or Zencash could be more profitable?  Just not stable?  I have given up on skein for now as zpool is slightly anoying as well as the price.

try
80% tdp
+70 core

the aorus is factory overclocked and pulls solid power 300 watts

I would not push that card  to the point it keeps crashing

so if 85% tip
and + 75 core = crash  do not set it that high.

This one is in a rig all by itself because I use it for gaming.  Has a EVGA 750W PSU.  It doesn't instantly turn off instantly crashes screens go blank and computer and card stays powered at whatever fan speed it was set to.  I shoulda explained that detail.

So I don't think it is anything to do with the PSU, yes it is an auros.  Some google shows most people can't go over +50 core.  So I was just wondering if I can run it at 75% power and +75 but not +75 and 85% power if that is safe or not.

For big setup like 1080ti, best to have 3 or 4 GPUs on a rig and get a good PSU and cooling.
At 70-75 TDP, you should get good mid-600sols per card well under 200watts with good efficiency 3.x
Cool, stable hash and undervolted is the secret to success.....

The 1600w EVGA is always on my test rigs so that it can take anything that i push at them.
Eventually this rig will be powered by a 1200w server PSU and 100% ZEC mining with nvOC Linux.

That's a beast of a PSU 

Was looking to change my setup to 4 1080ti's and was curious about what PSU is out there to do it with....guess I know now.

Newegg is showing it at around $360 out of stock, some others have it higher. Is this purely for density sake?  Wouldn't it be economically better to just make another rig for 2 cards and save on the PSU by using a 850W or so?

1200w/1300w to be safe

4 x Gigabyte Aorus
160core/100mem/PL=195@3000sols@870-900watts
MSI-Z270A-Pro, 4gb RAM, i3-7100, EVGA-G2-1600w
nvOC NVIDIA Linux

LAN did not work when launching smOS and nvOC Linux.

But Windows is OK.

I wonder if this board is a Windows only board.

Phil?

four 1080 ti's  could be 300 watts each if they are aorus

so 1200 x .85 = 1020 watts    so if you have a 1000 watt psu it may not cut it

if you hit the overcurrent protection on a psu rail (or whole psu) the psu just shuts down entirely. the rig does not crash, it just powers off.

at least on good psus, dunno about junk, but rigs should be running top shelf psus.

It seems to be a power cut off, you may be ovecharging one of your power rails.

I finally have all my settings where I want them thanks to everyone in this thread Phil etc.  My 4 1080ti's are mining away on ZEC (skein is not good right now).

One thing I am a little worried about.  When tweaking the TPD core clock and Memory clocks, if it crashes is this going to cause any damage to the card?

For one of my cards I have the settings at

TDP 70%
Core +75
Mem + 0
Fan 55%

Temp is 50C so no issue there.  But if I try to go above 85% TDP it will crash.  On 75% it is fine and has been running for around 1 week no issues.   Is it safe to keep running at +75 core even though I know it causes crashes to happen almost as soon as I start mining for anything above 85%?

I wish I have a link to all Philipma's account so I can know what to mine daily. Phillip, will you consider setting up an Telegram or Whatapps group where we will pay subscription monthly to know what you coin you switch daily? I will the first to sign up.
