5881  Alternate cryptocurrencies / Mining (Altcoins) / Re: GPU utilization on: February 26, 2016, 08:52:27 AM
I'm mining the x11 algorithm with my GTX 970 I have it set to only use 58% of the power with EVGA PrecisionX.
I wanted to try to lower the GPU utilization in order to save the wear and tear on my card as this is my main PC
Is there any way to lower the GPU utilization with ccminer?

or is utilization even the issue that I'm trying to correct if I want to save the life of the card?

Thanks in advance.

A GPU is a solid state device. No moving parts, no mechanics, therefore no wear and tear. As long as you keep to the default voltage and don't allow it to overheat it will last exactly the same amount of time running at 50% as it will running at 100%

 100% wrong.

 The hotter ANY electronic device runs, the shorter it's lifetime (on average) will be.

 Running it at 100% WILL make it run hotter.

 This is WHY manufacturers will VOID YOUR GUARENTEE if they can prove or have reasonable reason to believe you have overclocked a GPU (or CPU or any other device that has a clock that can be adjusted in it) - it puts quite a bit more heat stress on the components which shortens their lifetimes to quite a bit less than designed for.

I'm not yet 30, and have pretty much been listening to the same 5 CDs on crappy USB speakers since high school.

The problem is ... when you were in high school there wasn't any good music!   So I feel for you.

 3 Doors Down.
 Amanda Marshall.

 Just to name TWO excellent music makers from the early 2000s.

 I do concede that the majority of what I like to listen to is from the 70s, 60s, and 80s though - what most folks would call "Classic Rock" for the most part, with some oddball and off-the-wall groups thrown into the mix (Moxy Fruvous anyone?)....

 I wonder if there are more Gridseed 80 blade HS floating around than Antminer S1/S3/S5 ones - though I suspect the answer is probably "no", I also suspect a lot of the S5s and a few of the S3s and S1s are still in use. I also wonder how hard it would be to make a board that fit ALL of those options.

5883  Alternate cryptocurrencies / Mining (Altcoins) / Re: Gridseed Blade CRITICAL ERROR HELP MEE!0 on: February 26, 2016, 08:33:31 AM
I presume that's 6 amps per side on the blades - which is a bit marginal, but *should* be enough at the frequencies you're running them at if you're keeping the PS cool and they're reliable designs.

 I ran a couple of my non-fan blade sides on Zoomhash's 7-amp bricks for a long time without issues, but I had fans blowing on the bricks for better cooling.
5884  Alternate cryptocurrencies / Mining (Altcoins) / Re: Gridseed Blade CRITICAL ERROR HELP MEE!0 on: February 25, 2016, 10:00:45 AM
While the Gridseed blades may have defaulted to 750 Mhz, that was actually a pretty strong overclock given the VERY WEAK power setup on those things.
 Try dropping to 600Mhz or so and see if the problem continues.
5885  Bitcoin / Mining speculation / Re: Zeus Thunder X3 VS Antminer s3? on: February 25, 2016, 09:57:34 AM
To be blunt, both are outdated tech that are at best VERY VERY marginal to unprofitable even if you have very cheap electric.

 I really can't recommend either, though an S3 at least has a good rep for reliability and MIGHT manage RoI if you have free electric (and Sidehack is working on boards that should upgrade an S3 to competatively current sometime in the next few months or so).

 There's a reason Zeus quit selling miners - they never managed to make a competative product, and the ones they DID get made were very inefficient for the timeframe they came out (even their later X6 models couldn't match the Innosilicon A2 machines despite showing up quite a bit later).

5886  Alternate cryptocurrencies / Mining (Altcoins) / Re: NEW Home X11 Dash Miner for Sale DualMiner DM384M Legit or Not? on: February 24, 2016, 09:40:36 AM
It's entirely possible - but at this point it's either in pre-order status, or it's announced vaporware.

It's X11, per the announcement - NOT Scrypt. The company has other gear they sell that does Scrypt based on the old Gridseed GC3355 chip.

 The price seems a bit on the high side, and the legitimacy at this point is unproven.


 Cleverhash announed they were working on an X11 (and X13/X15 IIRC) chip quite a while back, but then apparently couldn't raise the funding to complete the work. There's nothing inherent to ANY POW type protocal that makes it impossible to create an ASIC for the protocal, the question is ECONOMIC viability = can a company SELL enough such chips for enough to pay for developing the things?
 If they start at 55nm, it seems much more viable for anything other than SHA256 or Scrypt (where the competition is already well past that stage), as development costs for an older process node like that are a LOT lower.....
5887  Alternate cryptocurrencies / Mining (Altcoins) / Re: Mining computer? on: February 24, 2016, 09:35:07 AM
The best would really to build a pc with 3 or 4 of the best video cards for mining Bitcoins in it.

 Error. No GPU will mine Bitcoin at a profit or even close, and even with FREE electric the cards will die before you ever made back enough to pay for them.

 Ditto for any other SHA256 based coin.

 Scrypt is almost as bad.

 non-Scrypt non-SHA256 coins are where to look at if using a GPU, though it appears that X11 (and possibly X13/X15) days of GPU mining for profit might be ending soon, *IF* the recently-announced ASIC miner for them turns out to be real and not vaporware/scamware.

 Unless you have VERY VERY cheap electric, or FREE electric, you won't make ROI on any currently available ASIC Bitcoin miner at this time. The upcomming 14/16nm full custom generation might change that.

 Scrypt with ASIC is viable right now even with not-real-cheap electric, if you go with any of the used A2 or Alcheminer units around, and POSSIBLY with the used Titan units around *IF THEY LIVE LONG ENOUGH* (the Titans are pretty notorious for their mining chips having dies go dead far too often, the A2 has proven to be a tank that just don't quit and the Alcheminers seem to have good long-term reliability as well but haven't been around nearly as long).

It's WAY too early for the effects of the halfing on Bitcoin price to be operating yet.

 What we're seeing now is more about the aftershocks of the Chinese markets being able to accept fiat payments again, that happened about 3 months back or so, coupled with the ongoing issues the Chinese economy is having.
5889  Bitcoin / Hardware / Re: Antminer S5 in a hot Texas garage? on: February 24, 2016, 09:18:14 AM
So I'm noticing the prices of the S3s and S5s dropping significantly.  I have 2 S3s and was thinking about adding an S5, but I have a few questions.

1. The S5 is as loud as a small vacuum, correct?

 Perhaps a small portable vacuum. It shouldn't be a lot louder than your S3s are.


2. I live in Texas where it's easily 100-105F every day from June-Sept/Oct and never drops below 80F at night during the summer.  I would want to put the S5 in the garage, which gets even hotter.  Would this be ok or would the S5 not be able to operate at such temps??

 Downclock it a lot. I ran mine during an Iowa summer without A/C, often seeing 90s, just had to downclock them some to avoid overheating and massive number of hardware errors.

 They stock clock at 350 Mhz, you should be fine and might even be a bit overkill running them at 300 Mhz (they'll go at least somewhat lower than that if needed).
5890  Alternate cryptocurrencies / Mining (Altcoins) / Re: [ANN] iBeLinkô DM384M ASIC Dash Miner on: February 22, 2016, 08:37:30 AM
I'd definitely want to see some of these "in the wild" before I put any money into them.

 Big case yet they seem to be using a 1U power supply - not real efficient use of space that.

 Cleverhash was working on an X11 chip (also X13/15 IIRC) but they apparently didn't have the funding to complete it.
 I do wonder if there's a connection.

 I doubt that DASH will change it's algorythm just because someone finally brings ASIC to it.
5891  Alternate cryptocurrencies / Mining (Altcoins) / Re: Start with mining help on: February 22, 2016, 08:29:51 AM
Gridseed actually DID make Scrypt miners - their GC3355 chip did both SHA256 AND Scrypt, but it's horribly outdated and a total money-loser on SHA256 now and it's at best marginal even at LOW electric cost on Scrypt - you'd never make your money back on any GC3355 based miner unless PERHAPS if you have free electricity.

 U3 is a SHA256 (Bitcoin) miner, you need to use a Bitcoin calculator like


 The U3 is also old and outdated, unless you have FREE electricity you'll never make enough mined Bitcoin to pay for it.

 Mining on a laptop is a good way to KILL the laptop, even if you have one with enough of a GPU to actuall mine with.
 I definitely recommend AGAINST that idea.
5892  Bitcoin / Mining speculation / Re: Mining Software, hardware, pool on: February 22, 2016, 08:20:58 AM
Bitmain and Avalon are currently selling miners, but IMO it's best to wait as there's a new generation of gear that's been announced to start showing up soon (probably the next month or two for the first units).

 I generally like Slush for a pool, but if you're serious about mining you should set up your own P2Peer pool node - I'll be doing that if/when I get back into mining.
 I used Elgius for a while, which was easy to set up but the pool itself wasn't so great.

5893  Bitcoin / Mining speculation / Re: how will 'micro miners' like 21 chips and bitfury lightbulbs work? on: February 22, 2016, 08:16:56 AM
The light bulbs might eventually show up - as a very small niche "fancy lighting" type product, as there's no way they're going to be able to target the "general lighting" market with the things. Not quite a non-starter but bloody close for practical purposes.

 Mining chip in appliances - total waste of time and effort IMO.
5894  Bitcoin / Mining speculation / Re: I am out of the mining game :( on: February 22, 2016, 08:15:15 AM
I made a profit on my S5s - barely - by selling them off "just in the nick of time".
I made a small profit on my SP20 by selling it off.

 Without those sales, I'd have lost money on mining Bitcoin (I'm officially out as of Monday when I ship the last of the S5s to Hawaii).

 I've actually made a fair bit on mining Litecoin so far, but that's been a bit rocky too - lost money on my Gridseeds, but made a fair bit back in GPU days and will end up still  ahead if I even achieve breakeven or very close overall on my A2s.

 The last few months, though, have been a nightmare for folks trying to get into mining and make a profit, unless they had VERY VERY cheap electric - and even then it's been iffy.

 The 14/16nm generation should be a game changer, though - instead of having a year OR LESS most commonly before the "next gen gear" hits and kills profitability on older gear, it should take a few YEARS before the 14/16nm full custom gear gets outdated.
5895  Bitcoin / Hardware / Re: Periodical Cleaning of Antminers on: February 22, 2016, 07:59:31 AM
Cleaning out dust accumulation should let the miner run cooler, which MIGHT let you overclock it a bit more without overheating it.

 Don't use an air compressor to blow out miners, they end up blowing WATER through the electronics = BAD THING.
 Might be OK if you have a water trap on the compressor and blow out the accumulation for a minute or two BEFORE you use it to blow out the miner, but even then it's a bit iffy.

 Vaccum cleaner is a MUCH MUCH safer idea, and makes less of a mess too!

5896  Bitcoin / Mining speculation / Re: i i want to start a project Mining on: February 22, 2016, 07:56:31 AM
Are you talking 1 BTC per month NET after electric cost, or GROSS before counting electric cost?

 Also, you are aware that the difficulty of mining gets adjusted appx. every 2 weeks or so, and it has usually gone up meaning you need more mining hashpower to earn the same gross income in BTC?
5897  Alternate cryptocurrencies / Mining (Altcoins) / Re: Safe to heat house with ALT coin mining rigs.?? on: February 21, 2016, 08:20:02 AM
I have been heating my home most of the time for the last 5 years with a group of computers (did litecoin mining on them for a year or so, 'till ASIC took over, then turned them back to my RC5/GIMPS efforts).

 This past winter, I've had to keep 2 windows (with thermostatically-controlled fans in them) OPEN all winter, due to the addition of some A2 Terminators and my several-month-long S5/SP20 mining farm (sold the last of THOSE units off today).

 You just need something reliable, miners work fine as "electric space heaters" if you buy reliable ones (and power supplies) or design and set up mining computers for reliablility (overclocking is a BAD IDEA anyway for mining, it's very inefficient).

 Also, on motherboards, if you're going to mine on them get versions that put heat sinks on the power circuitry. It's a MAJOR plus for reliability on any motherboard that's going to be running 24/7
5898  Alternate cryptocurrencies / Mining (Altcoins) / Re: GRIDSEED G-BLADE Overclocking 7Mh/s, improvements and repair on: February 21, 2016, 08:16:30 AM
Zeus or Gridseed vs. A2 based gear though is an even more impressive win for the A2.

Zeus was too inefficient when it was released to be competative, the ONLY thing it was better than was the GC3355-based gear - and that was more because Gridseed's board-level design skills were horrible, and their insistance on their stupid "dual mining" concept, than anything GOOD about the Zeus designs.

 Who the heck is / was "Joe Bloggs"?

 Also, your figures on the Gridseed blades are off based on the ones I had. I was routinely seeing under 100 watts for mine at anything up to about 5 Mhash, a bit over (110 perhaps) at 5.4

 Dunno why you are talking about burnout on USB ports, the gridseeds did NOT soak a significant amount of power from their USB connections - and their power ground was via that shitty barrel connector for 12VDC, not via a USB port that had ZERO connection to the +12vdc circuit (unless you were powering the blade from the same PS as you were running the miner software on).

 I never saw an issue of the Gridseeds struggling to get through a block - you must not have been on a well-designed pool or had them badly misconfigured to see that sort of issue.

 The REAL issue with the Gridseed blades was the shit design on the power circutry - if they'd had a decent design on that, they'd have been quite reliable.

5899  Alternate cryptocurrencies / Mining (Altcoins) / Re: don't use X11,many peopel use fgpa mining X11 coin on: February 21, 2016, 08:06:54 AM

I see someone has just ordered a nice amount of scrypt asics and wants us to mine scrypt instead of a asic-proof algo.

 NO algo is asic-proof.

 Some just don't have enough return for anyone to bother making an ASIC for them.

 Cleverhash WAS working on an ASIC for X11 (and X13/X15 IIRC) but they didn't come up with enough funding to actually make the thing, as of the last word I saw from them.

 And no, Scrypt ASIC *CAN NOT MINE X11* - original poster is lying through their teeth about that.

5900  Bitcoin / Mining speculation / Re: Why doesn't someone just design a miner, which will ROI and profit in a year? on: February 21, 2016, 07:59:51 AM
The main issue with the "design a miner" concept is CHIP AVAILABILITY.

 Designing custom ASIC to do cryptocoin mining is NOT cheap, and none of the current chip makers are selling chips at all unless you come up with a rather large up-front amount of cash to buy them (of those willing to sell AT ALL).
