2041  Alternate cryptocurrencies / Mining (Altcoins) / Re: Does CPU matter when mining? on: September 28, 2017, 12:49:56 AM
SATA power connectors are NOT designed to handle the power draw of a GPU - that may be your issue right there if you are using SATA-power risers.

 They're only designed to handle 40 watts or thereabouts, the riser is going to be putting more like 70-80 watts of draw on them.


2042  Alternate cryptocurrencies / Mining (Altcoins) / Re: Using the additional 6 pin power connector on RX 580s? on: September 28, 2017, 12:46:19 AM
I always see it mentioned that you don't need to use both the 8 pin and the 6 pin power connector when mining.


 I don't know where you are seeing this LIE, but any card with multiple power connectors will flat out refuse to work AT ALL if they aren't both connected.

 Trying to run on one will totally mess up the power circuitry ON THE BOARD to the point the board probably wouldn't work at all and might FRY that power circuitry AND THE GPU AND MEMORY, even if it DIDN'T check for both connected in the BIOS code before the BIOS enables the GPU for actual usage.

2043  Alternate cryptocurrencies / Mining (Altcoins) / Re: Manufacturing Gridseed Orbs AGAIN on: September 28, 2017, 12:42:36 AM
Good afternoon all,

So after reading about how people are only getting 400 h/s to low mh/s using GPUs.
I am thinking about getting GridSeed Orb boards manufactured. If I can find a manufacturer to make them of course.
I figure if I could get these boards manufactured and then put into a blade configuration inside a case, these would hash great at a lower total power cost and initial cost for entry level scrypt miners.

Thoughts???


 Waste of time.

 The GC3355 used in the Orb is very very outdated on the SHA256 side - it was UNPROFITABLE even during the last few months the Orb was being MADE, which is why Gridseed shifted to making the "blade" and "GBlade" models that were Scrypt specific.

 The SCRYPT side is no longer profitable unless you have FREE electric.

 It took a "blade" 40 chips to ALMOST MATCH the performance of the Futurebit Moonlander II (which uses a SINGLE chip, I believe the same chip the Innosilicon A4 uses but the maker has never confirmed or denied that), and the power usage was ballpark 10 TIMES higher than what the Moonlander II uses.




 The algorithms folks are seeing 400 hash/sec out of on GPUs are NOT SCRYPT.
 Scrypt hashrates would be more like 1-2 MEGAhahsh out of most recent mid-to-high-end GPUs, and a few of the top end ones should be in the 3-4 Mhash/sec ballpark.

2044  Alternate cryptocurrencies / Mining (Altcoins) / Re: INTERNET REQUIREMENT FOR MY ASIC MINERS on: September 28, 2017, 12:36:33 AM
I have 2mbps down and 256kbps up Internet link. How many ASIC miner can I hook with it without any issue Huh? ( What will be maxout limit in number of miners let say Bitmain D3s)
I can also add a LTE hot spot with atleast 10mbps up and down, but wired connection are more reliable as compare to 4G and LTE hotspots.
 Thanks in advance.

 Lots.

 I ran a multi-ASIC + multiple GPU rig farm for about a YEAR on a junk Virgin Mobile 3G connection that saw 200kbps DOWN on good days without issues from the mining.

2045  Alternate cryptocurrencies / Mining (Altcoins) / Re: Ubuntu or Windows for mining altcoins ? on: September 28, 2017, 12:34:39 AM
which is more stable and gives you more hashrate ? shortly which is better ?

You cannot find many miner softwares for Ubuntu OS and I don't think your hash rate depends on the OS you are using. You have to use the best best mother board, processor and high gaming console graphic card to get the high hash rate while you are mining any coin. Try using windows itself to get the s/w supported to you.

 Most major mining software writers support Ubuntu.
 In fact, I can't think of one that does NOT (though Claymore was anti-LINUX for a while he changed his stance when he finally realized how much he was LOSING by not doing so).

 Hash rate generally isn't OS specific - the differences are minor at most, and are normally DRIVER dependent issues not OS specific ones.

 The main tradeoff is that LINUX is more stable, but the tools for overclock and undervolt are a lot more primitive and don't work as well as Afterburner for Windows.

 You do NOT need a high-end processor AT ALL for mining, and mining motherboards don't tend to work well as high-end gaming motherboards as mining doesn't NEED the throughput to the GPUs that gaming does.
 I ran my triple R9 290 based ETH rig on a Sempron 145 low-end single-core CPU for many months, and saw ZERO hashrate change when I upgraded that rig to a Athlon X2 240 dual-core (the only difference is that ETH's DAG file generation went quicker, but that normally happens BETWEEN blocks and doesn't affect hashrate).



2046  Alternate cryptocurrencies / Mining (Altcoins) / Re: Cleanly cutting square tubing on: September 28, 2017, 12:26:35 AM
Hacksaw + miter box.

Circular saw + metal cutting blade.

Table saw + metal cutting blade.

Square tubing is EASY to get square cuts on as compared to round tubing (though the miter box and table saw methods both work well on round tubing, the circular saw method is iffier).



2047  Alternate cryptocurrencies / Mining (Altcoins) / Re: Are CPU only coins possible? on: September 28, 2017, 12:22:09 AM
There is no way to limit a coin to CPU only - if it gets popular enough SOMEONE will write a GPU miner for it.

 The best you can do it make it a "hard on memory usage" coin, like Monero, or make it something like BURST where the hashes are PREcomputed then stored on a HD, and are complicated enough it's difficult to impossible to compute them "on the fly" fast enough to matter.

2048  Alternate cryptocurrencies / Mining (Altcoins) / Re: Any potential issue powering an L3+ with two EVGA PSU? on: September 28, 2017, 12:20:23 AM
From a power standpoint, those 2 PS should work fine.

 Higher-end EVGA power supplies some with a "power test" adapter that is basically a "turn the thing on" plug that plugs into the ATX power connector, works well in a mining rig setup.
 I'm NOT sure if the GQ line includes that adapter, all of my EVGA are G2 models (I refuse to own any more PS with a "sleeve" type fan bearing, no matter how fancy a name they put on it they ALL die too fast in a high temp environment).

After some digging I've found this, although it's pretty expensive.  Will it fully power 10 units?

 You won't FIT 10 Moonlanders on that, the ports are too tightly spaced.

What should a 290x go for in your opinion?

 Ballpark $150-200, but won't see them THAT low 'till ETH profitability drops quite a bit more.

2051  Alternate cryptocurrencies / Mining (Altcoins) / Re: Claymore's ZCash AMD GPU Miner v12.6 (Windows/Linux) on: September 28, 2017, 12:07:18 AM
Hello guyz,

Can i dual mine zcash and zencash? GTX 1070

 They use the SAME algorithm, that stresses the SAME parts of the card.

 The point to Dual Mining is one algo will be MEMORY heavy (ETH) the other will be CORE heavy thus allowing more full usage of the ENTIRE card.

2052  Alternate cryptocurrencies / Mining (Altcoins) / Re: Sixth alt coin thread I forgot to mod last thread. on: September 28, 2017, 12:05:25 AM
I hope that somebody makes one with ample enough spacing to run a full 6-8 higher wattage GPUs, such as GTX 1080 Ti, Rx Vega etc.

Looks like your prayers were answered :

Colorful recently launched a 8 GPU motherboard, similar to the boards in the Pandaminer and clones.


 And it's "standard" 2 card spacing, NOT wider for good cooling.
 Note that the Pandaminer was designed around PASSIVE COOLED mobile-type GPU cards - one of the reasons it has so many case fans - and thus it can get away with closer spacing while still having good cooling.


2053  Alternate cryptocurrencies / Mining (Altcoins) / Re: Sixth alt coin thread I forgot to mod last thread. on: September 28, 2017, 12:03:19 AM

i don't get what citronick is saying about "better heat control" but risers are imoprtant to make space between hot gpus, the closer they are together the hotter they get..

quality risers are good, most of my risers from late 2013 are still going strong.

Avoid the molex powered risers or any of the v1 to v5 risers.


 Why avoid Molex - the connectors can EASILY handle the needed 75 watts (the actual connectors are rated for about 150 watts IIRC) as long as the WIRING is beefy enough.

 Avoid SATA definitely, those connectors aren't rated for more than about 45 watts and WON'T handle the load.



 to rslx - if you're willing to wait, your best choice is to buy from the manufacturer(s) direct.

2054  Alternate cryptocurrencies / Mining (Altcoins) / Re: gpu bubble well and truly bursting on: September 27, 2017, 11:58:43 PM
just transferred zec to polo, will cash in and buy 3 more 1080ti, anyone wanna sell theirs cause whole cryptoworld is going to collapse very soon Cheesy

Dude stop copying. I just sold some too. Let them panic sell. We need gtx 1080ti going for $500 and less.

 Probability ZERO as long as it is the current "top gaming card".

 Be happy it's back in the $700 or a bit under range again, where it was in January.

2055  Alternate cryptocurrencies / Announcements (Altcoins) / Re: Gridcoin (GRC) - first coin utilizing BOINC - Official Thread on: September 27, 2017, 11:57:17 PM

in this post (in the comments) you can see what the new portfolio will look like in the next update: https://github.com/gridcoin/Gridcoin-Research/pull/517   


 Still wasting a ton of screen space.
 The third most irritating thing with the current wallet is the HUGE amount of wasted "white space" in it that makes it a PAIN to be able to see what's going on without completely overloading the entire screen.
 #1 isn't actually the wallet itself - it's the "have to keep tons of coin around to stake in a reasonable timeframe" issue.
 #2 is the frequent wallet CRASHES that have returned with the current version.
 #4 is the "I want to pop up FULL SCREEN IN THE MIDDLE OF THE SCREEN" when started, instead of following STANDARD WINDOWS PRACTICE of start up in the location and size the window was when it was LAST CLOSED.

 I get TIRED of having to REPOSITION AND RESIZE the bloody wallet every day or two due to the combination of the last 2 issues, AND having to re-UNLOCK FOR STAKING every time.

 Why doesn't the wallet AUTOMATICALLY stake instead of having to do that stupid "unlock for staking" every bloody time the wallet is started up?
 It gets OLD having to "unlock for staking" every bloody time the wallet is started up.
2056  Alternate cryptocurrencies / Mining (Altcoins) / Re: EWBF's CUDA Zcash miner on: September 27, 2017, 11:46:04 PM
I'm running a RIG with GTX1070 all with same overclock and power setting 65% power +100 GPU +600 MEM
and I have often crash with error code Thread exited with code: 46

anyone can help me ?


 Chips VARY - it's inherent to the semiconductor manufacturing process, and has gotten worse with each generation of process as the size of the "features" on the chip gets closer to the size of atoms the chip is made out of.

 ZEC isn't memory intensive, unlike ETH - try dropping the overclock on your memory ENTIRELY.

2057  Alternate cryptocurrencies / Mining (Altcoins) / Re: gpu bubble well and truly bursting on: September 27, 2017, 11:43:07 PM
The "bubble" has burst when we see new 1070's @ $320 or less, 1080's @ $420 or less, and 1080 ti's dropping into the low $600's

bubble bursting has nothing to do with cost of GPU. How do you even come to that conclusion ?  Huh

They are talking about the cost of GPUs, that started to go up in price at the beginning of the year (or was it March?) because of increased mining demand. Not a coin bubble. For a while it was impossible to find some GPUs.


 Late Febuary/early March timeframe for AMD RX 470/480/570/580 cards as I recall, about a month later the price on those got so high that the NVidia GTX 1070 and then 1060 cards started getting affected as well.
 Look for when the big ETH price spike started, add about a week for the initial GPU price climb to start, 2 weeks later the shortage was in full swing and the prices were going through the roof - then ballpark 5-6 weeks later is when NVidia started getting noticeably hit on the 1070, add a couple more weeks and the 1060 started getting hit noticeably.

 Never had a noticeable direct effect on the GTX 1080 or GTX 1080ti (By the time the good NVidia ZEC miners started showing up, prices had flattened out and the overall demand was starting to drop) but there may have been some indirect effect from gamers that WANTED the 1070 and decided to "move up" when the 1070 price got into 1080 levels, or due to massive widespread 1070 shortages.

2058  Alternate cryptocurrencies / Mining (Altcoins) / Re: Good Network Switch? on: September 27, 2017, 11:36:46 PM
Used Cisco, Netgear Blue Box, and 3Com gear tend to be good - I've got an old 3Com 100BaseT switch that I bought used at least 15 years back, still working reliably.

 I'm distinctly NOT fond of TP-Link or D-Link stuff, had too many issues with both over the years, though TP-Link seems to have done some work on reliability in recent years.


2059  Alternate cryptocurrencies / Mining (Altcoins) / Re: Anybody knows about "Antminer D3"? on: September 27, 2017, 11:20:24 PM
An interesting way to make money at the expense of customer naivety.
Why does Bitmain not want to send Antminer on a regular basis? https://shop.bitmain.com/ (sold out)
If they would send the devices up to date, then they would have sold a lot fewer devices, because day by day it would be a noticeable mining difficulty.
However, it is better for them to sell the maximum number of devices two months earlier, because it will not immediately increase the mining difficulty. Mining will fall drastically when the devices they send are connected to the network.
If the customer sees that it can get a lot of money, then he buys many devices right away and sends money two months earlier. If the same customer would see the day-to-day difficulty of mining increase, then he bought much less because the mining difficulty would increase dynamically with each sent device.

I don't think you understand what is really going on.  When they make the S9 or D3 they DON'T sell itThey mine with it for months making a large amount of money.  Only when the difficulty increases to the point they can sell it with what appears to be a decent ROI does it go on the market to the rest of the world.  Selling the miners is kind of the icing, not the main profit. 

Would you do it any different?  If I had a miner for ETH why would I ever sell it?  I would be making far more mining with it than paying to produce it in large quantities only to make 1k for each unit.  I have the only one, no competition.  Once the difficulty naturally gets to the point that I can make more profit selling the units, only then would you offer your "new" tech to the masses. 

 The large bulk of miners that Bitmain makes DO in fact get sold fairly quickly - days or weeks at most NO MONTHS.
 Most of the rest are part of their Hashnest operation.
 If they mined with them for 2 months then sold them, we would have seen a HUGH hashrate jump 2 months ago on X11 (for one recent example).

 If they WAIT to sell it, they have to DROP the price quite a bit BECAUSE the diff increased in the meantime - and the capitol investment in those miners is TIED UP SO THEY CAN'T USE THAT MONEY TO BUY MORE CHIPS FOR THE NEXT BATCH TO MAKE MORE MONEY WITH.


 YOU are the one that doesn't understand the economics of the situation for Bitmain.
 They don't have infinite cash to work with  - and foundries don't do "credit" with small operations IF they do "credit" at all (I doubt even AMD or Nvidia or Apple get "credit" terms with the foundies - Intel and Samsung don't need to worry about it as foundry owners).

2060  Alternate cryptocurrencies / Mining (Altcoins) / Re: Burst Vs Storj Sept 2017 on: September 27, 2017, 11:14:35 PM
Don't think I'd ever BUY HDD's for this but I have them already now.

 With one single exception, that's MY tactic.

 Gotta add the HDs to new rigs anyway, might as well make them big enough to be useful on BURST (at a SMALL increase in cost).


 84 drives in one machine is incredible - even Backblaze only manages 60 on their current Storage Pod design (though they've moved to at least 4 and might be moving to 6 or 8 TB per drive so their total pod CAPACITY is likely a bit higher than yours).

 32 TB of drive is slightly MORE expensive (at NewEgg pricing on the Seagate Externals) than most GTX 1080 ti cards - which pull in close to $3/day each at this point.
 Tradeoff is the ELECTRIC usage of that 1080ti will be in excess of 160 watts and more likely close to 200 watts to achieve that income level, while the 4 hard drives are eating around 50 watts AT PEAK and quite a bit LESS most of the time.


 Up side of those Hitachi (HGST) 2TB is they're likely to last a long time, I'm NOT fond of WD in comparison and I'm VERY not fond of most Seagate models for longevity (I don't have a large data set on Toshiba but the set I DO have has been quite negative, close to Seagate low levels).
