1001  Alternate cryptocurrencies / Mining (Altcoins) / Re: is there a consistent relationship between mining difficulty and coin price? on: December 29, 2017, 09:38:57 PM
I have contemplating about this and even consider capturing data however havent had a chance yet.
I presume if the coin price plummets then people will lose interest and move to other profitable coin and as a result, falling coin's difficulty would decrease but so far I havent quite noticed that with zcash. Sometimes it seems opposite is happening.
But I'd really need to capture long term data over long enough time range to see any relationship and/or pattern being observed.

No, there is no direct relationship between the two.

There IS a direct relationship between both of those and PROFITABILITY though.

Price rises DO tend to fuel higher difficulty over time indirectly, as PROFITABILITY increases and folks build more rigs to take advantage of the profitability increase.


Many folks "chase the profitability" into coins that briefly spike on profitability - it tends to even out most coins over time fairly closely but often takes a day or two and sometimes might take a week.
Folks that don't "chase the profits" STILL benefit some as hashrate leaves the coin they're on to "chase the profitability" - and they don't lose any mining income while they are switching their rigs over to another coin.


When I look at whattomine, I NEVER look at "current profit" - I normally look at 24 hour average as a minimum, and more commonly at 1 week average, before I decide if it's worthwhile moving my farm to something else.
Other folks are more "gotta max out to the limit"....


To be explicit, as it's been asked before - difficulty does NOT cause price rises, it's the other way around but not directly, and there is a lag factor involved (a really BIG one the past year and some on Bitcoin and Litecoin due to limits of ASIC manufacturing, a lesser but significant one for some months this spring when most GPU coins shot WAY up and rig-building couldn't keep pace).

The Titan V tensor cores are Floating Point - dunno if they can be used at all for Integer type work like ALL CRYPTOCOIN MINING uses.
They also are optimized and designed to do "matrix math" - which has NOTHING to do with the straight adds/rotates/move the date work used in Cryptocoin mining.

nheqminer hasn't been updated for a long time - it's not a good basis for comparison any more.
The current miners to compare are EBWF, this one, and that new BMiner thing for Windows.
I forget if Zawata's new miner works on equihash at all, if so might want to include it in the list.

 It'll be pulling more once you put GPUs in and have the CPU actually doing some work - but not likely to be a ton more, that's a low-power CPU and most mining software doesn't put a high load on the CPU.
 Do keep in mind that a system at "idle" often turns the CPU clocks down a lot for power savings...


1004  Alternate cryptocurrencies / Mining (Altcoins) / Re: Mining farms for heating houses? on: December 29, 2017, 09:15:35 PM
Depends on how much power the rig uses and how much heat the room NEEDS to stay warm.
It's definitely providing heat, even if the fans are at only 25%.

 I kept an old poor-insulation mobile home warm through 2 IOWA Winters (the first one of them a record-setting cold winter) with my mining gear - and had to keep 2 windows at least cracked open with fans running in them to avoid OVERHEATING the place that second winter.

 That wasn't "one rig" though....

What AMD driver are you guys using for mining?

What is the latest version? Do they plan to release a new version of blockchain driver in near future?

Block chain version - 17.40 or whatever it's listed as.
AMD has stated they do not plan to do another version of that driver, they APPEAR to be incorporating the changes in that driver into the "mainstream" drivers the past month or so.


 Memory ability to overclock VARIES, sometimes from chip to chip.
 930 935 940 and rarely 945 seem to be the most "common" clocks that Vega56 memory will handle on a stock card.

 Welcome to the Silicon Lottery, where most miners live pretty close to the edge!

1080 not TI is almost the same price as 1070ti in local stores. What do u think should I prefer for one small rig at home with 4 cards. What power block capacity would be enough for this?
thanks for answers. Wink

I have to warn you that there is a problem with 1070ti with neoscrypt algo, the performance is really low - same as 1070 card, no boost
but if you will not mine coins on that algo - tale 1070ti, properly overclocked it will be only 5-10% slower gtx1080

 Heavy memory limited algorithm most likely, same as ETH where the 1070 ti ALSO has pretty much identical hashrate to the 1070.


 I don't hate the 1080 - I just have yet to see an algorithm where they are the most optimal choice.
 They're usually CLOSE to 1070 / 1070 ti / 1080ti on a hash/$ basis though - and details vary with the card and the SETTING you run the card at, sometimes they're VERY VERY close sometimes it's an easily noticeable difference.

My Zotac 1070 minis IME pushes the same hashrate as normal 1070 cards to a point, but tends to be a hair slower when pushed close to the max TDP of the Zotac since they run hotter and can't boost QUITE as high.
My Zotac 1070 ti mini MATCHES my EVGA SC 1070 ti cards when used at "max efficient" settings, I've not tried it at any other operating point.
My Gigabyte 1070 ITX cards (before most of them DIED) pushed very close on hashrate with anything else at the same settings but a HAIR slower.
My MSI Aero ITX_sized card was a hair slower than anything else at same settings, and had WORSE cooling than any other 1070 I have used (including an ASUS Turbo blower model).

Can't speak to 1060 cards as I don't own any.

Overlock GTX 1070 can increase hashrate to 510~520+ Sol/s, each card.

But it's may be unstable(crash, black screen etc.), you need to do some test, find the right settings of your card.

 Overclocking memory on a GTX 1070 doesn't seem to help noticeably IF at all on equihash mining - overclock CORE does help some usually.

 Might depend on the specific card though.


My Gigabyte 1070's and 1070ti's definitely benefit from both core and memory overclock.  I have done extensive testing and both seem to increase hashrates independently, around 5 to 15%  I only mine equihash.

 I didn't say anything about 1070 ti cards here - and do keep in mind I'm the one Voskcoin credits with the "+200 +700" settings he used in that first 1070 ti equihash rig video of his. 9-)

 Many of my 1070 cards ARE Gigabyte, and dropping memory from +500 (as high as they go and stay stable) to -500 had ZERO effect on hashrate.
 Might be power level related, since I'm running them around 105 watts for EFFICIENT mining, not pushing them for max hashrate.
 Might also be a difference between LINUX and Windows or the specific drivers, but I doubt that.

1009  Alternate cryptocurrencies / Mining (Altcoins) / Re: How can i mine using my Laptop? on: December 29, 2017, 06:21:54 AM
Unless you are using the laptop to control USB miners, where the actual WORK of mining is not being done by the laptop, VERY VERY BAD IDEA.

 Laptops are NOT designed for high-power usage 24/7 like mining imposes on a machine, you probably WILL kill the laptop fairly quickly if you try to mine on it.

This is also probably the 50'th time AT LEAST this question has been asked since I first started visiting this forum.





Only the 50th?  You've been here much longer than I have and I feel like I've seen this question 50 times.

 Must have been a typo, I am pretty sure I meant to type 500th.

 
1010  Alternate cryptocurrencies / Mining (Altcoins) / Re: Sixth alt coin thread I forgot to mod last thread. on: December 29, 2017, 06:17:01 AM
1080's have a tiny bit better than 1070 Ti's?

If you aim for max efficiency, 1070 ti will at least match and usually beat 1080 hashrate in the 100-110 watt power range at the same power usage.
This depends on the card model and sometimes the specific card, I've only seen ONE match situation on "same model" cards, my Zotac Mini 1080 vs my Zotac Mini 1070 ti - but that's a case of the 1080 Mini I have being THE BEST 1080 I have in that power range by a bit.

If you push for higher hashrates at the cost of efficiency, the 1080 starts outhashing the 1070 ti typically around 120-125 watt level but never outhashes a same-model 1070 ti by the common 10% cost differential, presuming same power level on each card.

 *IF* you can get a "same model" 1080 for the same price or within 2-3 % of a 1070ti, it's probably worth doing IMO - otherwise no.

I'm running a 6GPU rig GTX1070's hashing good 2,655 Sol/s. Running PSU 100%.
Do I really need to change the clock settings?

It's not that Ubuntu has poor AMD support - it's that AMD has poor LINUX support since the move to AMDGPU-PRO when it comes to those of us doing compute-type work.

1013  Alternate cryptocurrencies / Mining (Altcoins) / Re: Suggest GPU on: December 29, 2017, 05:58:35 AM
7970 = R9 280x as I recall.

 They're so-so ETH miners, ballpark 14 Mhash as I recall, with "proper" overclock settings.
 Fair ZEC miners, I want to say ballpark 300 sol/s

 Power cost IS an issue with older cards like that, but they should be profitable as long as you're not paying crazy-high rates like Hawaii or much of Southern California.

 Might also look into using them on the Milkyway BOINC project to earn Gridcoin with - Tahiti has VERY good FP64 performance that project needs.

1014  Alternate cryptocurrencies / Mining (Altcoins) / Re: How much would it cost to build mining rig? on: December 28, 2017, 09:56:20 PM
The PSU should be a EVGA or CORSAIR 1200 watt , fully modular and Platinum rated like the Hx1200 from Corsair, this PSU can keep up 5 cards even if they are running near 200 watt but that is not the case because when you are mining Ethereum they are consuming 135 watt each from GPU-Z or MSI afterburner app.

I would advise you to buy 6x 1060 GB 3GB for 1200 USD which would be a better choice, the consumption would be much lower than with RX 580 and you can mine Zcash to get approximately the same amount as for 5x RX 580. Make sure to buy a good motherboard for mining, like ASROCK H81 PRO BTC which supports 6 cards easily.

 The ONLY Corsair line I will even look at is the AX - the rest all use CHEAP JUNK "fancy name" sleeve bearing fans that do not last at high loads.
 The AX line happens to be basically the old Seasonic SS-series Platinum rated power supplies with some very minor changes (same platform as the Seasonic X-series Gold supplies).

 EVGA G2/P2/T2 line is good, but I don't know if they still make them.
 Their newer G3/P3/T3 line has those junk "fancy name" sleeve bearing fans, I won't even LOOK at the things.
 EVGA GQ line uses junk "fancy name" sleeve bearing fans.


 The H81 Pro works well, but it's Socket 1150 which is getting hard to find decent low-cost CPUs for.
 I have no idea what they changed on the "rev 2" of that board vs the original, but since the original is long out of production it doesn't matter much any more if you don't already HAVE the original.
 I think they make a H110-based update to that board that is socket 1151 and otherwise pretty much the same.


 The GTX 1080 isn't a real good mining choice - it's not BAD, but it gets beat on efficiency by the 1070ti on NVidia-friendly coins and the 1070 beats it hands down on ETH - not that the 1070 should be mining ETH anyway, it makes more on other stuff.
 1080 isn't a BAD choice - just not optimal on hash/$ or hash/watt though close vs the other NVidia options.

 AMD high-end Polaris cards do well on Ethash coins (ETH/ETC/related), fair on Cryoptonight (Monero), and tend to not be all that good on much of anything else (probably some small niche coins they do well I don't know about though) though not BAD, just not optimal....

1015  Alternate cryptocurrencies / Mining (Altcoins) / Re: Seems there is a couple different versions of the Nvidia 1080ti on: December 28, 2017, 09:45:12 PM
The EVGA SC Black is my favorite GTX 1080 ti model.

 It doesn't cool as well as the MONSTERS like the Aorus or Duke or Amp Extreme, but it cools WELL ENOUGH and then some if you are aiming for efficient mining, and the 8 pin + 6 pin power connectors setup is a LOT easier to deal with on a multi-card with than the higher-end cards with their dual 8-pin connectors.

 I also appreciate the relative LACK of worthless funky LED lighting - I wish they'd get rid if the part that lights up on the top of the card, but that's relatively minor compared to a LOT of cards lately.

 The LEDs might not eat a noticeable amount of power, but it takes MONEY to do the design work AND to incorporate the LEDS and their circuitry and connectors into the card, which makes the card more expensive by SOME factor.

 The ASUS Turbo (blower model) is my second-favorite - if it cooled better it might turn into my favorite though, as it's usually the lowest or one of the 2-3 lowest priced cards available at any given time.

 Both cards get my attention at least in part due to their BALL BEARING FANS.



1016  Alternate cryptocurrencies / Mining (Altcoins) / Re: Some Newbie GPU mining questions on: December 28, 2017, 09:40:43 PM
If I have to mine on Windows for some reason, I vastly prefer to use 7 over 10.

 Heat generation is going to depend on the power the rig draws.
 For an easy comparison, a common portable "room heater" draws about 1500 watts on it's high setting.

Lowest devfee = you pay US to use your miner?

 Genoil IS free after all....



 Pretty much EVERY legitimate cryptocoin miner program gets "false positive" virus warnings from at least ONE major virus checker - BUT those warnings are normally "heuristic" warnings, NOT "specific virus" warnings.

 "Online virus checkers" tend to go overboard - they have to justify their existance SOMEHOW after all....

1019  Alternate cryptocurrencies / Mining (Altcoins) / Re: Suggest GPU on: December 28, 2017, 09:27:26 PM
That website is a joke - no facts presented, just blurbs.

 The "best" card depends a lot on what you want to mine - and which has the best ROI varies, often day to day and sometimes hour to hour as difficulties and prices change on the various coins.

 RX 470/480 pricing of late when you can find them at ALL have tended to be higher than pricing on the newer RX 570/580 - performance is more or less a tossup between them, depending on the coin and memory size as much as the model in some cases.
 Outside of Ethash (ETC/ETH/related) mining and POSSIBLY Monero mining, they're only so-so on hash/watt and hash/$ - but they've VERY GOOD at Ethash mining and fairly good at Monero.
 Might be some other "small niche" coins they rock that I don't know about, but when you're talking altcoin GPU mining ETH and ZEC are the BIG TWO - all others are small in comparison.

 Vega - outside of Monero and EVEN THEN only if you can get them at fairly close to MSRP on the reference cards, they're beat badly on hash/$ on everything else I've seen hashrates posted for.
 On Monero though they are the current KING if you don't get gouged badly by the price killing your hash/$.

 GTX 1080 ti - is the highest hashrate on a lot of coins, but is often beat on hash/watt and hash/$ by lower-end Nvidia cards like the 1070 ti - though it's usually CLOSE, and it can make rig management easier to have fewer cards.
 Not a BAD choice, just not always the best depending on your goals.

 GTX 1070 - it's flexable and can mine a lot of different coins well, but almost never the best by any measure.
 Call it the "Utility Infielder" of mining - good at many things, but not a star at any of them.

 That site doesn't even mention the GTX 1070 ti - the current KING on mining Equihash coins (ZEC/ZCL/ZEN/related) efficiently (Titan V beats it on hash/watt but is HORRIBLE on hash/$) and quite good at the other members of the list of "Nvidia friendly coins".


 Then there is the issue of "the next generation" tending to shake things up - right now, that's the upcomming NVidia 20xx "Volta" cards, due out in a few months (one comment by an EVGA employee in their forums I remember was talking about "Feb/March" as a timeframe for the first consumer Volta cards).
 Based on published mining tests on the Titan V, it looks like the Volta cards are going to be roughly 25% more efficient than the current Pascal line - and AMD isn't going to have an answer to them at all for months after THAT.

1020  Alternate cryptocurrencies / Mining (Altcoins) / Re: ANYONE USING NORMAL FAN FOR COOLING??? on: December 28, 2017, 09:06:56 PM
A standard Lasko/Galaxy box fan only eats 50-60 watts ballpark if it's on it's HIGH setting - it eats a LOT less on low (probably 20 watts perhaps less), which flows enough air to keep a FEW rigs cool.

 Most case fans that blow noticeable airflow at all eat 4+ watts PER FAN, and you generally need more than one to keep a SINGLE rig cool.

There's a reason my newest "rack/shelf" unit is designed to run 6 rigs with 2 standard box fans to move air through the unit.

 The box fans are also a LOT less expen$ive than buying a BUNCH of case-type fans to achieve similar airflow (even my Hamfest Special used NMB fans were $2 each, and that's VERY cheap for a good server-type case fan - new ones commonly hit $10 ballpark EACH).
