Insane Crypto-Currency Mining Rigs

Hah, I knew creating a Mining/Crypto section would bring in the vocal dissenters. I just wish they'd add some value to the commentary.
 
You mean, instead of coming in, dropping a grenade and then taking off never to be seen again?
 
The smart money is 240V circuits. Power supplies typically run a couple % more efficient at 240V and it's typically a cheaper and easier upgrade since you don't need to run new wiring if you stay at the same current limit.

I hate to break it to you, but most of us who mine don't have a single card that hits 90C. Most of the cards are not in an enclosed case like gamers. They are in open air rigs that run a shitload cooler than anything used for gaming.

My hottest rig is open on TightVNC right now on my desktop and the temps are:
67C
69C
72C
76C
and Its been running for 48 hours.

Its funny how most people think that mining somehow destroys your cards. I've been mining since August of last year and I have RMA'ed 5 of my cards. 4 of the 5 were MSI cards the fans died on and three of them were almost 3 years old, (6870 cards).

Its funny how most miners compare it too people game on their rigs 24/7, when in reality that's farthest from the truth... and then throw lower 24/7 temps at you like it doesn't have any bearing on the life of the card...there's a reason you see cards for sale that now include "never used for mining". Stop the excuses...

Believing someone who is selling an AMD GPU that say "never used for mining" should be about as believable as someone selling a high mileage car saying "all highway miles".

It's only included in there because people (I'm assuming like you) care about it for no good reason.

I've been running computers full tilt 24/7 for the better half of a decade crunching whatever the popular distributed computing project was at the time using whatever was popular at the time cpu/gpu/etc. I've had one s775 motherboard fail on me.

Only part that should fail with regularity is the fans. But I've replaced a lot of case fans.

meh, I flogged my trio of unlocked 6950s at max hash for 3 years, all still running fine, IMO thermal cycling is more harmful than constant load

No good reason my ass...if you had one you mine'd for 3 years and one you didn't then tried to sell them with full disclosure, which one do you think people would purchase? Of course people like you miners are going to say it doesn't matter. I sure as hell wouldn't expect the card to last for 3 more years after that. Fan, gpu, or memory doesn't matter as its all out of warranty.

Are you butthurt you can't get a "dirt cheap" radeon card to mine yourself? You can't complain about GPU prices for gaming because nvidia is still a solid market for gaming cards. I'm willing to bet you are just someone who is too lazy to invest the time/energy/money to make crypto work for you. You are pissed that everyone else is making cash sitting on their ass, so you go into troll mode.

No and No. I am not invested in either AMD or carrying about what people do with their cards. Those who are mining are simply gambling. They hope they win and I hope they lose just for the sake of the absurdity and flat out mockery that has spawned after BitCoin reached ridiculous levels and people needed to create a new scheme to put their hardware to use.

It's a bubble that will pop regardless of what I think and people are eventually going to lose. That's called: markets.

But like the other guy said... you're too late. The smart ones have made enough to pay for their stuff already. Me? I have not only paid for my stuff months ago, but I will be able to pay for more to expand my setup, plus still have more left over to help pay for a new vehicle. I know it hurts you to hear that.

But, what I do is my own business... I don't give a flying rat's ass whether you like it or not.

You guys get waaaaay too serious. Not everyone hates you or is talking shit. They are simply voicing their opinion in general. If you take offense to that you need thicker skin because you're free to do whatever you wish with whatever you purchase.

Good for you that you made off like a bandit, but as I mentioned above eventually people are going to lose. Not everyone can be a winner just ask those gambling in the stock market. EVGA offers money to Fold for them, so it has nothing to do with people making profit from putting their gear to work. The mining thing has just gotten silly and any long-term chance it had as an alternative currency is quickly being diminished.

Don't take things so personally. Making assumptions that weren't even there to begin with: mountains out of mole hills.

Your analogy was completely off basis. Not only is it irrelevant to the original comment, you're assuming I'm jealous of nice things. lolwut?

Wishing someone harm and betting on someone to lose is completely different. Miners are betting on winning and others are betting that they lose. Don't step in the kitchen if you can't handle the heat. Individuals like yourselves must never have walked into a Casino.

Again your crypto cats jump to conclusions: anger, jealousy, vindictiveness, AMD's soaring prices, etc. My comment painted a picture of nothing. Obviously you don't understand how dry humor works on the Internet one bit and have taken something you're obviously passionate about and made it into something more.

The only conclusions to be made here is your delusional assumptions of what a person was really trying to say.

For those who don't read into things to this absurd level: I'm on the other side of the betting table.

[EDIT] This was a Front Page story, yet taken directly from the Mining Forum. My goal wasn't to offend those of you whose passion this is. I figured this would be a neutral ground which probably explains the confusion. I wasn't intending on coming here intentionally and shitting up your AO if that's what you think. Original comment wasn't intended the way it might have been perceived and I can now see why that is lol.

Those are some pretty good temps if they're 290Xs. From what we've seen of 290X testing, they pretty much ramp up as high as they can until they hit the 90c cut-off, and then stay there. If you're hitting the max boost bin and still only running at 76c, then props.

Or are they all the 6870s you where talking aboutl? I was pretty much assuming and referring to 290 series cards simply because people are really interested in the 290s but just can't get them due to the fact they've become the mining card of choice. Gamers really aren't clamoring for older cards at this point. When someone comes in here and wishes for altcoins to die so they can get a cheap card, they're thinking bargain priced 290Xs.

By the time that happens they will have been earning 4-6 figures for months years or gpu will have slid down to useless for this... honestly everyone who says aww it is a bubble is fooling themselves the dot.com bubble burst yet there are still dot.com springing up yeah they are not instant millionaires but they are still here bubbles are myths... i have been mining for 1 month i have 2 video cards if this shit bottoms out tomorrow what am i left with computer hardware so i stop mining go back to playing games.

Honestly AMD would do well to try to market/design towards miners enough to specifically make the gpu out preform asic... Hardcore miners have made the all of the amd cards fly off the shelves it would not surprise me if amd had eyes like dollar signs.

I can only imagine when asic make gpu mining for scrypt pointless amd crying over the huge loss.

The reward free money the risk piles and piles of computer hardware.

you have to realize to get the best hash from a card you don't do like you do for frame rate alot of times you overclock the ram and underclock and undervolt the gpu example my r7 260x hashes best at 750mhz core (stock is 1100) with 1600mhz ram (stock) when i do that i do get hardware errors and i need to adjust some other settings xfx doesnt let me adjust but it gets about 80 more kh stock i get about 189kh/s oh and when i put my card to the best settings my temps go down into the 60's where as at stock it is 70-71 my 270x hovers around 65c

have you seen the video of him getting approached my a protester asking where his money is at? The CEO just had a stupid smile on his face holding his frozen coffee in t-shirt during a blizzard in japan. All he was saying was for the guy to get out of the way. I hope he gets fucked hard financially.
 
Just how productive are those USB miners, i mean compared to vid cards they must not be that great..but obviously use alot less power and put off less heat.
 
the block erupters were the shit when they first became available, like all crypto hardware they did not age well
 
ya i just read this one example from Aug 2013.

A typical USB block erupter will get 333MH/s under realistic conditions. Today, a share is worth about 1/156 of a penny and 333MH/s will get you a share every 13 seconds. That comes out to 43 cents per day per erupter, not counting the cost of electricity. Difficulty is going up, and thus profitability going down, around 25% per month. So you can figure maybe $11 your first month, $8 your next, $6 the next, then $5, and so on. You might get about $50 before it becomes more trouble than it's worth.

But then why not spend $1400 on one of the butterfly labs cards?

Basically with their little $249 boxes by April, you loose money

Thats the whole problem with your argument. Its not a gamble and it cost practically nothing to get started to dip your toes in the water. Most of us already have a nice gaming video card, I just kept ordering more with the money i made. Im up to 12 gpus with 2 more on the way. I mined bitcoin a few years ago and made about $2200 total selling my bitcoin on average for $6 each. Yes, i was foolish but I never saw mining as risky.

1.) I am buying hardware I love, even if bitcoin died id still have these sweet 5870 / 7970 that paid off half their cost in the first 6 weeks. After mining is gone, they are still valuable to gamers. (i tend to sell complete gaming computers on craigslist rather then sell the gpu seperate)
2.) Bitcoin has been around 4 years now and the trend line is still way up, not only that but a bunch of successful asic resistant altcoins have spawned making it even less of a gamble.
3.) Mining is more profitable now then it ever was with bitcoin. Back in the day I had 7 video cards and my best month made $250 after electric. My first month mining litecoin alts I made almost $1000 after electric and even with drop in bitcoin price i project to make $900 in the next 4 weeks. When you buy used cards off craigslist for $100 or 290s at MSRP, they pay themselves off QUICK. so any hopes you have at laughing at gpu miners is pretty much doomed. You can however laugh at the fools buying asic devices that go obsolete long before they even ship. *cough* butterfly labs *cough*

That's pretty cool, actually. The mental image everyone gets when they hear "used for mining" is tortured hardware, if the cards are well cooled and potentially undervolted and underclocked as well, they'd be considerably easier to resell. Keep that in mind when you list cards in the classifieds.:D
 
DO WANT... I'm only supernewbtastic.. But, I do have (4) 290x on the way.. For gaming, with a side of mining.. Anyone have a PSU to recommend?

Get risers, full 16x for gaming or 1x for mining, either way, get powered risers. If you don't then you have to get expensive PC PSU's to power it, even if you got a server PSU to power the GPU's you'd have to be able to give the board 500w+ (assuming 125w CPU) of 12V power. Since you don't want to be maxing out the PSU you'll probably want to aim for ~ 50A of 12v power (600w), and that's just to power the CPU and the 4 pci-e slots, not the rest of the power the GPU's are going to be drawing from the second PSU you have plugged into them.

You're much better off getting risers and powering them all from el cheapo server PSU's, this way your mobo/peripheral PSU only has to be pushing ~ 20-25A of 12v power, which almost all PSU's do, and I'd bet that you have a PSU laying around that'd work just fine.

SilverStone ST1500 1500w

I have 3 of those PSUs running on 3 quad 290 rigs, no issues whatsoever. It has 8 25a 12v lines.

Total power draw is ~1400w @ the wall according to my killerwatt.

EDIT: Here is [H]'s review of this unit.


LEPA 1600w too, if you can find one in stock.

I've got 4 of the smaller 1200w units and they are still chugging along after 10 months of 24/7 mining.

What's the big idea with these powered risers? Do they simply act as additional power-injection so that the mobo/cpu PSU doesn't have to work as hard? Will they fit within a Caselabs M8? I think so, right?

I do have some old Dell PSUs kicking around at work...

I looked at Lepa, but I think I read a bunch of recent reviews that claimed they were ALL DOA or dying...

I found a new Cooler Master Silent Pro M2 1500W for $200, you guys think that is going to be suffice? I'm going to watercool the cpu/gpus, I know they run a bit more efficiently then, but enough to put me within the threshold?


I appreciate all the help guys!
 
Dammit! I feel like all of them have horrible reviews! What the hell... I wish seasonic went up to 1500... Should I go dual seasonic 860 or something? Money is almost no object.. I just want a stable, safe, and efficient system... What is the "correct" answer to this? I'm using a caselabs M8, so dual psu will not be an issue.. But is that considered the right way?
