Topic: My #1 GPU Mining Rig - Let Me Know What You Think! (Read 650 times)

You have to watch it for when it is mining for dev fee.

 --fee is effective - but it's not as cut-and-dried as it could be, due to how EVERY miner I've seen that imposes a fee for use does so.

 --fee set to 0.2% might not actually GIVE that low, but it's noticeably lower than the default 2% does from when I was monitoring it to check.


 It's unfortunate zawata never got his FREE zec miner up to speed to be competative....

 It would also be interesting if wolf0 decided to build a ZEC miner - might still be fee but performance would probably beat anything current.

EWBF has 2 - 3.8%? I Didn't know that .

Hi QuinLeo,

How do you know the real fee is just 0.2%? And how to set that fee?
As I remembered EWBF's miner has the fees of 2% and somebody did tests to figure out that this miner has a average fees of about 3.8%, and the command --fee seems not effective.
Thanks!

Did some OC and left my rig for the night.

Power 85%, Core +85, Mem +400 - This was the most stable setup so far.

Here are the stats for zCash from nanopool:

Let me know your tips

 Rig density on the 1060 is WAY too low for me to bother with them on anything except PERHAPS ETH - if I was doing any ETH mining at all.

 1070 ti is the current efficiency champ for ZEC/offshoots that is affordable - technically the Titan V is more efficient but at $3000 a card it is a TOTAL FAIL on hash/$.

 The Titan V does indicate that the new Volta upgrade cards will probably be 20-30% better efficiency over any current Pascal card - but gotta wonder if NVidia is going to bump the price on the new cards given that they'll be noticeably better than anything AMD.


 The Zotac Mini 1080 ti SHOULD be efficient if you run it at a low enough power level - try it in the 150-180 watt range where it's cooling system should be able to keep up.
 I wouldn't buy one due to the apparent lack of ball bearing fans (their AMP Extreme line brags about it's ball bearing fans, but their other cards are suspiciously silent on the subject) but if you already have it might as well use it effectively.


 BMiner on pretty much ALL of my rigs will not even load - since it's a Windows-specific program and I'm a major fan of the RELIABILITY of LINUX in a mining environment (and the very few Windows rigs I still have are getting moved OUT of Windows due to the low stability of the junk).
 I've also not been real impressed with it's posted hashrates - barely better than EBWF but you lose most of all of the improvement to the FIXED fee.
 Same issue as with DTSM except that some of my testing has shown DTSM giving SAME OR LOWER hashrate as EBWF on the same card at the same power setting.

 EWBF miner is quite happy to run at a 0.2% fee (which I consider a LOT more reasonable for a widely-used mining program of comparable performance).

ZOTAC 180 TI Mini is slow. zCash 707 Sol/sec. and my 1070ti are 509 Sol/sec.

ZOTAC was almost 2x the price! I fucked up ....... and learned my lesson.

it's better if you also go for the non-mini version of your gpu as they tend to throttle a lot, and i don't think 250gb is really necessary, 120gb is enough for big virtual memory for certain coins

Thank You guys so much for the help!

I'm running now on 80% Power.

3.33 Sol/W so far Small improvement.

Decrease the power limit to 85% and observe the hashrate for 1-2 hours. From there onwards decrease in 2% steps to fine the optimal settings. Keep in mind that not all the cards will behave identically so it might be that you need individual settings for best performance.

try not to go over 70C. just keep em cool. give em some fresh air my rigs have also the fans not on auto. i was playing around with each gpu to keep em under 70c

OK. Will try with more OC. So far it's all stable. GPU temp is around 68-73C per card.

was just reading what you wrote

I’m a little late to the party but went overkill on the CPU but glad you fixed the PSU. Your really need to play with your OC settings and you will be able to get much better hashrates.  I would try even up to +150 core +600 memory and see if it’s stable at 70% if you got Samsung memory in your GPUs it might be possible.

My PSU is:

EVGA SuperNOVA 1200 P2, 1200W, 80 PLUS Platinum

I'm OK .... i think

Will change Power Limit. Thanks!

Yes, you will get much better sol/watt ration with almost same speeds. try for each card individually. if you use MSI afterburner it is called power limit
and please try to swap out your PSU for a better one

Wow expensive rig, your processor is overkill i think, pentium is enough 
Equihash algo i recomendation you to mine Bitcoin Gold, i think this is more profitable than ZEC
Good luck sir

I already did +100 Core and +500 memory on all cards using MSI AfterBurner. What's a TDP? Power consumption?

u need to play with your settings to get the best bang for the buck (efficiency) try to use +150 core and +400 memory and tdp 75% and check your results

My Rig is online.

Now i'm mining zCash

Thanks.

It's best to upgrade my rig with 1070 TI or 1080 Ti in the next 2-4 weeks or maybe go with more 1060?

I guess you bought good premium hardware and rentability of it will about 8-13 month

Hardware ordered!

Thanks for all the tips.

I switched PSU to EVGA SuperNOVA 1200 P2, 1200W, 80 PLUS Platinum (220-P2-1200-X2)

And GPUs:

MSI GeForce GTX 1060 6GT OCV1 6GB GDDR5
MSI GeForce GTX 1070 Ti Gaming 8GB GDDR5
Zotac GeForce GTX 1080 Ti Mini 11GB GDDR5X

My goal is to learn as much as i can. That's why I decided to get different GPUs to see how each one performs and what to expect.

I will use SMOS on a USB stick.

Will keep You posted as soon as I finish my build.

EVGA G2 line is the Superflower "Leadex" platform, IIRC.
Not sure on FSP, haven't had any experience with them.
Corsair - depends on who MADE it, some are Seasonic made and I think they might have one line that is SuperFlower made, the rest tend to be lower quality to junk.

When it gets right down to it, there are perhaps 10 companies that actually manufacture standard ATX type power supplies - and most of the "well known brands" are NOT on that list.

I dunno about the mini version but all zotac's with 2 or 3 fans use good and reliable ball-bearing fans at least im sure for the AMP/AMP extreme version (dual-ball bearing EKO fans on those)

I also agree with your choice of PSU's, seasonic and EVGA are very good brands, i would also add FSP and superflower in the mix, very good too. Corsair's are ok, but the quality is variable.

Cooling on the Zotac Mini 1070 ti is ok, but not great - the 1080 ti version is going to be VERY VERY iffy on cooling.
It's also a question on if Zotac uses ball bearing fans (they don't say they DO, so probably they DON'T) = early fan death for anything else in a mining environment.

i5 for the CPU is overkill, but you did state "gaming rig" as a backup plan so it makes some sense in context.
Set it up to do Monero mining or some such will help some on the cost difference.

IMO go with at least a Gold rated power supply - and IMO one of the EVGA G2 or Seasonic X-series over anything Corsair (some Corsair models are good, many are JUNK, and I've given up trying to keep track of which are which).

 If you're looking at 6 1080ti cards, you need AT LEAST a pair of 850 watt PS unless you are going to run them a much lower than stock TDP *AND* can set the power limit RELIABLY.
 Otherwise, use at least 1000 on 3 cards + rest of system and at least an 850 on the other 3 cards - and at full TDP for 1080 ti cards more like a 1100+ and a 950+ to handle the power peaks mining generates reliably.
 Dual 750s should be OK for a 6 x 1070 ti build as long as you're not pushing the TDP above stock, though an 850 + 750 would be better if you ARE going to run the cards at full TDP.

Your i5-CPU is very strong, I usually use just intel celeron g3930, 250Gb SSD is expensive as well, if you want to use it for installing wallet, it'fine, but if it's not the case, just use 64Gb or 120Gb. I dont know how many GPUs you want to build in this rig, normally I buy PSU based on the total GPUS' TDP, for example: 6*1070 has total 6*150W = 900W, I will buy PSU could handle 1200W (just guarantee PSU runs at below 80% loading).

Also you can use your CPU for CPU-only coins. That is good enough for lyra2z330 coins of scrypt^2 (like Verium). i5 7400 is quite power efficient CPU so you don't need to pay much more for the electricity. And of course as many already said here should upgrade the PSU

The power supply is really weak. He will not have so many lines to connect the GPU. You will need to connect a separate power supply. For guaranteed work 6 GPU I use a power supply 2225 watts. My first rig was working 2 GPU. This was the limit for my power supply is 750 watts. To the rest of the equipment I pritenzy not.

I see. Will look for 1000+. Thanks!

Go for at least 1000w PSU and gold rated, just in case you wanna expand your rig.

I’ve been doing some research for the past 2 weeks and i decided to build my #1 test mining rig or a gaming PC if i fail at mining .

My plan is to build simple mining PC with NVidia GPUs to learn how to mine. If successful i’d like to scale and add 4 more GPUs to the current build and add more rigs in the future.
#1 priority is to have fun with small and easy build and learn as much as I can in terms of mining, optimisation and overall strategy (hodl or trade mined coins)

I based my research on best YT channels:
