I'm fully aware of the issues of moving - I just DID so last summer.

 If you're going to be serious about long-term profitable mining, though, you NEED to get somewhere with low electric cost.

1942  Alternate cryptocurrencies / Mining (Altcoins) / Re: Best GPU's to mine ZCASH with? on: October 08, 2017, 05:31:19 PM

Really cus my G1 does 500+ easy. Im pretty sure if you get your hands on a good 1070 it could come close to a 1080 maybe within 5%.
Mind you electricity for me is free though but I dont want to invest a lot (wont be buying the Vega cards anytime soon).
I'd stick with 1080Ti or 1070 and forget about the 1080.

 I have never seen a 1070 that managed more than about 460 - SPECIFICALLY INCLUDING my Gigabyte G1 cards.

 You apparently have one that handles a lot higher overclocks better than most do, or you're looking at the "momentary peaks" and counting those as the hashrate where I tend to look at the AVERAGE hashrate instead, or you're in a VERY COLD ambient temp with your cards - or a combination of all 3.
 

 Even with minimal tuning and having "fairly high ambient temp cooling" limitations, most of my 1080 cards easily hit 530 and I suspect when I take the time to fine-tune them they will be able to push closer to 550 - and NONE of those are "high end" 1080 models, most are the Zotac Mini or the bottom-end Gigabyte 2-fan models which are definitely heat limited in my environment.


 On the other hand, with 1070 pricing getting back down into the pre-gouge range, the 1070 is starting to look like a better option even at the system level to the 1080 in many respects - and the recent climb in 1080ti pricing isn't helping any.


1943  Alternate cryptocurrencies / Mining (Altcoins) / Re: Nvidia 1060 vs 1070 vs 1080 vs 1080Ti on: October 08, 2017, 05:23:52 PM
With the 1070 finally getting back under $400 (Newegg pricing, saw 2 of them today at $399) it's taking back it's place as arguably the best NVidia mining choice for most algos NVidia is good at.

 1080ti pricing seems to have been going UP a bit lately - I can't remember the last under $700 listing on Newegg for one, been a month or so I think.

 1080 ti is still better from a "rig density" point of view, though, and any of the 1070/1080/1080ti options are close on both hash/$ and hash/watt when you figure them at the TOTAL SYSTEM COST AND POWER CONSUMPTION level.


 Gonna be interesting to see where the "1070 ti" specs end up at, and pricing on it, and where it falls in the efficiency and hash/$ spectrum - presuming it DOES actually happen.

Card keeps overheating.  Nvidia, linux CUDA.  Help Smiley
just mining on the supernova pool.


 Try setting the fans to something faster than the "factory stock" fan profile - which in all "good for mining" cards I've seen to date worries too much about "quiet" at the cost of "cool".

1945  Economy / Scam Accusations / Re: Is Syan a real deal? on: October 07, 2017, 05:43:27 PM
The S9 isn't best in class - Bitfury was showing similar efficiency to what Syan is claiming on their demo

Bitmain can also hit that efficiency with their chips and have shown it. I dont get how you can argue the S9 is not best in class right now by the numbers. Show me a bitfury miner I can purchase right now? Show me ANYONE thats ever seen a Syan? BW couldnt match efficiency in a retail product, neither could Canaan, neither could Bitfury, neither could Ebang....the list goes on.

 Bitmain has NOT shown that level of efficiency, though they've shown somewhat CLOSE to it on the first few VERY UNRELIABLE batches of the S9 - and stopped trying on the later batches as the miners could NOT operate reliably when pushed that close to their bottom voltage spec for max efficiency.

 BitFury chips are used in the Hotmine X5/X6 line of miners, among others I don't remember offhand.

 BW doesn't SELL retail, you're arguing strawmen there - and we don't KNOW what the efficiency on their current miners ended up at, their CHIP level claims however did in fact beat Bitmain and were in Bitfury territory for their "3'd gen" 14/16nm chip design claims.

 Canaan beats Bitmain HANDS DOWN on reliability, at a cost in efficiency.

 I never mentioned EBang, YOU are the only one bringing them up.
 Another strawman argument since I never made ANY claim about them at all.


 It's nowhere near as cut and dried "Bitmain is the best" as you claim.

1946  Bitcoin / Hardware / Re: how do you wire a 220v line for multiple miners in the US? on: October 07, 2017, 05:30:25 PM

With that in mind, I'm going to use three 741s on two 2400w PSUs.  That should be about 1800w for each PSU for three 741s.


 I ran my S5/SP20 farm the same way when I had it - 3 miners on a pair of Seasonic X1250 or EVGA G2 1300 supplies.

 Just make sure each hash board is powered from the SAME power supply and you should be good to go.

 It also gave me plenty of headroom to crank that SP20 HARD (it was the "middle" unit on it's trio/pair).




1947  Alternate cryptocurrencies / Mining (Altcoins) / Re: $800 Electric Bill . . + My Current GPU Mining Profitability on: October 07, 2017, 05:21:23 PM
13548 kWH for August. Effective rate $0.08265

$1119.80

 You should move.

 My last bill was under $600 (barely) for a bit over 13kwh usage.

 Hair under $0.046 all-up rate.

Where are you located / can pm if you’d like

On that topic where is the cheapest electric in the country? Or perhaps a top 5 list?

 3 counties in Central-Eastern Washington - Douglas, Chelan, and Grant.
 Residential and SMALL business rates in the first two are around 3 cents/kwh all up, Grant 4.5-4.6 all up (the rates are near identical between the 2 classes of service in each county).

 Large business rates in all three (200kw level for them all IIRC) is well under 3 cents/kwh all up.

 Most of each county is covered by a "County PUD" built fiber network that was originally set up for remote meter reading, but the counties lease access out to local area ISPs for end users to get connected to - usually on a 100Base-T Ethernet link (faster is available but I suspect it takes time to get the panel modified or swapped out).

 This is WHY there are a lot of LARGE major corporation data centers in Quincy (Grant County) and most of the largest cryptocoin farms in the USA are in the area (Gigawatt that used to be known as MegaBigPower, Zoomhash, Toomin Brothers, Columbia River Mining, to my specific knowlege and I KNOW I'm forgetting a couple and am sure there are others that are "under my radar").



 24,000 KWH / year is not much power - 66 KWH a day or well under 3KW total draw on a continuous basis.


 MOST areas I've ever lived in had lower "residential" rates than "small business" rates, but it varies depending on the specific power company involved. Never hurts to check into it, and potential other options like "Time of Day" rate that can often lower your power bill when they are available.

I use 3 phase all the way to the PDU  xy xz yz
As in the PDU's have 3-phase line-in and split it off to 3 banks of single phase pairs inside of the PDU's? That would be pretty damn handy...

 I think I've seen at least one high-end PDU do that, but I'd be more inclined to suspect he splits the 3-phase out to single-phase and feeds the PDUs from the single-phase.

 Liebart is comming to mind....

1949  Alternate cryptocurrencies / Mining (Altcoins) / Re: Mining Zcash on: October 07, 2017, 04:56:21 PM

Superb dude. I am not involved in mining big. I am research about mining and finally now arranging to go with the 2 altcoin mining rig one is for eth and one is monero. I will go with Nvidia 1070 TI cards 6 numbers in each rig. Will it profitable to mine Zcash with the specification I said. SSD would 64 GB and 8 GB RAM.

 GTX 1070 is overpriced at current pricing for ETH mining - you'd do better to build an ETH mining rig around AMD RX 470/480/570/580 cards now that they're commonly available under $300 again.
 SSD is a waste on a pure mining rig - I'd go with a low cost hard drive or a USB flash drive instead.
 8GB is overkill for a pure mining rig but does offer some future "room to grow", and it's not all that much more expen$ive than 4 GB any more.

 Yes, your planned rigs SHOULD be profitable on ZEC mining - as long as your electric cost is not crazy-high.
 I CAN'T say if it will achieve ROI though, way too many variables like "future ZEC pricing" that I don't know and NOBODY can predict, and I also have no idea what your electric cost is like.

Any insights/experience as to whether something like this

could work for powering a _single_ miner?

 Per the specs, it should work well even for an high clocked Moonlander.

1951  Alternate cryptocurrencies / Mining (Altcoins) / Re: Which Switch Brand/Model is best to go with on: October 06, 2017, 08:35:36 PM
Hello Friends

I am planning to buy Switches and need some expertise.

The plan is as follows

2 or 3 Internet Providers Cables goes in to  >>> Load Balancer  >>> VPN/Firewall Router >>>  Main Switch >>> Each cable from it goes to another Switch (which is mounted on the rack, that has 8 Rigs)


Internet Load Balancer


I am planning to go with PEPLINK Brand maybe 305 or 380. Or should i chose the lower models. Or any other brand you recommend


VPN/Firewall Router

Please suggest brand


Main Switch (Which of the below options is best) - Is Managed Switch better or Un Managed Switch ?

TP LINK  -  T2600G-28TS   -  Managed Switch
TP LINK  -  T2700G-28TQ   -  Managed Switch
TP LINK  -  T2600G-28MPS  - Managed Switch

DLink    -   DGS-3120-24PC  - Managed Switch
DLink    -   DGS-3120-24TC  - Managed Switch

From the above which one is the best option for the MAIN SWITCH


Switches on Racks (each rack has 8 Rigs) -

TP LINK  -  T2600G-28TS   -  Managed Switch
TP LINK  -  T2700G-28TQ   -  Managed Switch
TP LINK  -  T2600G-28MPS  - Managed Switch

DLink    -   DGS-3120-24PC  - Managed Switch
DLink    -   DGS-3120-24TC  - Managed Switch


Should i go with the Managed Switch or Un Managed Switch for the switches on the rack?



Thanks for your assistance. Please let me know if you suggest any other brand or model, so i can look in to that as well


Thanks.



 No need for a seprate "load balancer" - quite a few options available to go from 2 or 3 WAN ports to your local network in firewall/VPN routers and I've never seen one that could NOT be configured for load balancing.

 I would IGNORE Dlink or TPLink for switches entirely.
 Cisco (ignore their "small business" line of relabled LinkSys junk) if you can find them cheap, used 3Com when you can find them, Netgear "blue box" pro line in their GS series, all are MUCH MUCH MORE RELIABLE long-term.

 Managed switches on a mining setup are a waste of money, unless you can get them cheap - might be usefull if you insist on trying to remote manage you miners from outside your LOCAL lan, but otherwise don't bother.

I mean right now on amazon 1080ti cards are going for $945.. and you're limited to 2 per customer


 $700-$750 for an assortment of different 1080 ti models on Newegg.

 Still doesn't add up to 200%+ margin though.

1953  Alternate cryptocurrencies / Mining (Altcoins) / Re: X13 miners? on: October 06, 2017, 08:26:09 PM
The older Baikal miners (based on their original chips) were the ones that support X13 - the old Cube 900 etc models.

 I *think* I remember them mentioning that their new chip in their current miner can support X13 but they have not enabled that support in the firmware of their new miner yet.

When you factor in TOTAL SYSTEM price, the 1050 and 1050ti start falling quite a bit behind most cards that have widespread usage in mining.

 1070/1080/1080ti are good efficient and cost-effective cards on ZEC/ZEN/other splitoffs and some small niche coins using Skein/Groetsl/lbry type algos, but don't support as wide a range of algorithms well as the high-end AMD RX series cards.


It's hard to give a definitive answer to this sort of question because the parameters to make the choice VARY too widely, sometimes on an individual basis.

1956  Alternate cryptocurrencies / Mining (Altcoins) / Re: Any interest in non-standard width "server" cases? on: October 06, 2017, 07:58:35 PM
If your case was designed to fit in OpenServer style racks, there might be FAINT interest in it.

 Most folks that mine with "cases" on their miners want 19" due to it's widespread availability and relatively low cost.

1957  Alternate cryptocurrencies / Mining (Altcoins) / Re: How to test EVGA 1300W G2 PSU without ATX cable on: October 06, 2017, 07:57:04 PM
Didn't you keep the "power supply test adapter" that the EVGA G2 ships with?

 Rectangular plastic piece with a connector inside, a hair longer than the ATX 24 connector and designed to plug into it with pins 4-5 shorted to start up the PS like a jumper.

Also if the chip is 25% more efficient than the current best in class S9 you would think they would be plastering advertisements whereever they could. They could completely take over the bitcoin hardware game if these machiens were legit.

 The S9 isn't best in class - Bitfury was showing similar efficiency to what Syan is claiming on their demo - and there have been "upgrades" to both GF and TSMC processes since then that make the efficiency claims of the Syan unit reasonable.

 That doesn't mean they are NOT a scam - it just means that *IF* they are a scam, they're a well thought out scam.

 They're also not the first company to come "out of nowhere" with a new miner - a few of which have proven to be legit....

your settings for 1070 to get 425sols at 65% tdp?

how about settings for 1080ti to get 800sols at 80% tdp?
 

I can not do 800 sols with any 1080 ti


 Best I've managed out of my Aorus is about 790 - but that was PUSHING it with a bit over 100% TDP (105 I think, for 262 watts) and +150 core +100 memory.

 80% figure (200 watts) more like 720 sol/s ballpark, +150 and +100 (which seems to be the sweet spot for this card at ANY power level 75% or higher, lower it starts crashing at the +150 core setting).


 My Gigabyte 3-fan Windforce model overheats if I try to push it at all, it's currently pulling a little under 700 sol/s at 215 watts +120 core +100 ram (It's on a LINUX box where TDP is set direct as a watts figure not a % figure).
 
 ************************************ AND OMG ********************************************

 It's on a riser for cooling reasons - and still pulling about 70C at 80% fan at a ambient of about 85F, despite the reduced TDP setting.
