My #1 GPU Mining Rig - Let Me Know What You Think!

[EasternRig]

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.

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

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

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.

Thank You guys so much for the help!

I'm running now on 80% Power.

3.33 Sol/W so far Small improvement.

I see. Will look for 1000+. Thanks!

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

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.

[QuintLeo]

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

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?

 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).

[EasternRig]

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:

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!

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

[QuintLeo]

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.
