Cryptocoin Mining?

[KingFatty]

Hey guys. Appreciate some insight:

- Motherboard: MSI 970 (2 x 16 PCI-E, 2 x 1 PCI-E)
- CPU: AMD Samperon 145
- RAM: Crucial 4GB DDR3
- PSU: EVGA 750w (80+ Gold Certification, ave 89% efficiency)
- CASE: Open air plastic milk crate

He is asking $1500. It looks like the cards go for $350 each on ebay.

NO way. I think $700 is justified for the two video cards, but how does he get to $1500?

Look at the selective list of items I quoted above after deleting the video cards and operating system. NO way is a motherboard+RAM+CPU+PSU worth $800! Plus they are AMD motherboard and CPU, making them very little value.

Maybe those parts would be oh around $125? So that leaves another $675 to account for. Hmm, I guess he has a solid gold milk crate encrusted with diamonds for heat dissipation?

Do not pay someone an extra $675 to assemble some low-end computer parts into a milk crate.

Instead, just buy two video cards and put them in your computer. Sell your 6950 if you need to make room; you can still get good money for the 6950 because it can mine. Otherwise, maybe you can just get some "risers" and add as many video cards as your current computer supports.

Thanks for the insight guys.

He has it listed on ebay, and so far has $1,100 worth of bids, but it hasn't met his reserve yet.

I might offer him $1000 cash. $700 for video cards plus $300 for the rest of the stuff along with coming to my house, setting it up, and showing me how to use it. But with the ebay bids doesn't make sense.

I'll just reassess if I want to buy my own video cards and make my own rig. I live 5 minutes from a microcenter so can get everything but video cards for dirt cheap.

Hey guys. Appreciate some insight:

I am currently just mining days and evenings (work/sleeping) with my gaming PC (single 6950). Very small time. Just got into it a few months ago. However, being a tech guy, I'm fascinated by this process. I also think it could be a fun hobby. So, I've been looking to expand, for 2 reasons:

1) hopefully make money
2) learning/enjoyment

A guy on my local craigslist has the following for sale:

- Motherboard: MSI 970 (2 x 16 PCI-E, 2 x 1 PCI-E)
- CPU: AMD Samperon 145
- RAM: Crucial 4GB DDR3
- PSU: EVGA 750w (80+ Gold Certification, ave 89% efficiency)
- GPU: 2 x Sapphire Radeon R9 280x
- OS: SMOS Linux bootable from Usb
- CASE: Open air plastic milk crate

He says the cards are two weeks old and everything is running great. He gets 1420 kh/s with about 500w power consumption. They are running at 1.161 volts each. The rig is running SMOS Linux from a bootable USB stick (included) and doesn't require keyboard, mouse, monitor, assuming you can start it up and SH (shell) into it (I don't know how to do that but he said he'd help set it up).

He is asking $1500. It looks like the cards go for $350 each on ebay.

What would be a fair price for this setup?

How many BTC per day would I get at 1420 kh/s? My electricity cost is $.075.

I appreciate insight/suggestions!

That guy is making at least $400 profit.
80 or so for mobo+30-40 for CPU+50-55 for RAM+120 for PSU+800 for GPUs=$1080-$1085 NEW.

Obviously, there is some payment for the labor costs he is willing to offer, but $1500 is still stretching it.

He probably means ssh, and it is pretty simple. You use putty or WinSCP if you're using Windows. You need to know the machine's IP address and user info. You use Xming if you want to run apps via the X window server(don't need it for mining).

Do this:

4x Sapphire 270
http://www.newegg.com/Product/Produc...82E16814202090
$230 each = $920

Biostar H81 mining board
http://www.newegg.com/Product/Produc...82E16813138394
$70

Intel G1820 Celeron
http://www.newegg.com/Product/Produc...82E16819116974
$50

2x 2gb DDR3
http://www.newegg.com/Product/Produc...82E16820231274
$45

EVGA 750w PSU
http://www.newegg.com/Product/Produc...82E16817438007
$85

Grab a cheap flashdrive and boot Linux. Need to buy 4 1x - 16x PCI-e adapters for around $15 each as well. This will get you 1.6 - 1.7 kh/s for $1230 plus the cost of the flashdrive.

This system should profit around $175-200 per month with your electric costs at current prices and difficulties. Rough estimate.

After doing some serious research into investing into another rig, I can confidently say you can also go the route with 750tis for more or less the same price, same 1.7-1.8mh/s but much less power consumption.

I wasn't sold on that concept at first myself but I've recently seen a rig with 6 750tis pulling less than 400watts from the wall on full load hashing more than 2mh/s peak and the only reason it wasn't 7 of them was because some glitch made the last card not run at full speed. This is also running on software that's not yet fully optimized for maxwell too; the guy who curates the cudaminer code claims that he's been receiving help from nvidia engineers who've implemented a bunch of optimizations not yet in the latest commit.

I actually stopped by my local MC today and they had MSI 280X Gaming for $349.99. Ironically, the MSI 270X Gaming was $300+ ($319 or $329, I can't remember)...

At $349.99 it's a pretty nice deal. At least 50 bucks cheaper than anywhere online, unfortunately I can't justify the purchase (until I sell my 7970) nor can I flip it for a reasonable profit because of the 8% sales tax, so I passed up on the deal.

You could also wait for the Radeon 265s to come in stock @ $149 and get roughly 10% lower hashrate (compared to the 270s) for 35% less $$$.

That guy is making at least $400 profit.

I wouldn't necessarily call it profit if he is asking for $1500 on ebay and the bids are only up to $1100. After all the shipping and fees, he will be lucky to pocket more than $200 worth of profit if he manages to sell for $1500.

plus he has to run the risk of return . as not working properly on day 44 of the 45 day return period is something buyers do.

The poster I quoted mentioned craigslist, a site in which doing transactions with shipping are likely to end in disaster and hence they advise you to only deal locally. The cost of gas and time might be real, but there aren't any middleman fees like the ones Ebay charges. Things are also sold as-is. It is a healthy profit if someone bites on the deal. Again, his labor costs might be real and worth charging, but at the same time, old parts should not be going for the same or higher price compared to new parts.

DOGE has dropped to only 140 satoshi... I'm tempted to sell all my DOGE now...

 

[philipma1957]

anyone mining vertcoin? A few people have asked me to check it out.

If anyone here does vertcoin please advise a good pool.

and what would i do with a pair of:

280x's = how many coins a day
290's = how many coins a day

I'm mining vertcoin on SuynnyD's pool:
vert.poolminewith.us

Here is pretty good vert mining calculator:
http://www.verters.com/vertcoin-mining-calculator
mining vert gives half (around 40%) of regular scrypt mining hashrate

Strange thing with vert is that difficulty is going up but the price slowly goes down which is opposite to what should be happening.
I think vert coin is good longterm investment and it may be a reason why people are not so excited about it. They are more interested in pump&dump scam coins.

 

[hondaf17]

Thanks for the commentary about the rig that guy is selling. It's still at $1,100 on ebay but it hasn't met his reserve yet so I doubt it'll sell.

I may offer him $1,000 cash, no fees, shipping, etc, if he comes to my house, sets it up, and shows me how to use it. The cards are worth $700 so $300 extra for power supply, mobo, processor, ram, delivery, his time, and saving me time from having to build the thing sounds reasonable to me.

Thanks for the suggestions.

Yup.... The markets will stay irrational for longer that you can stay rational, etc.

I believe it will go back up, but I don't know if it will go back up to 200 levels.... I bought a few @ 190, but nothing crazy. I'll keep holding to see what happens.

After that large increase in BTC --> USD value I assumed their would be a lot more interested buyers, but it looks like all that are interested and actually willing to buy a coin or 2 have done so. Maybe BTC will stabilize? Booooooooooooooooooooorrrrrrrrrrrrrrrrrrrrrrriiiiiiiiiiiiiiiiiiinnnnnnnnnnnnggggggggggggg.

In the future you should check the costs of everything yourself in order to familiarize with prices. Just take each individual part, for new go to amazon or tigerdirect and for used just check ebay prices. Not buy it now's, but what actual auctions are going for or the LOWEST of the buy it now's for that items... they are "worth" typically slightly less than that.

I made a post about these mining rigs earlier in the thread. It's crazy that people will bid on this stuff. The problem with selling them though, is that the only people that would actually buy them wouldn't have the first clue how to use them properly so you will get tons of complaints, questions, negative feedback, etc.

If you want to mine effectively and for anything other than short term, you'll need to build yourself IMO.

You need to know how the rig is setup, how to deal with heat, how to adjust/fix. Buying pre built miners is shooting yourself in the foot unless you are buying something that is Falcon-NW quality.

You'll need to tweak and get familar with a miner to get the most out of it. First step for that is to build your own.

It might make sense to buy a miner if you really know what you are doing and want someone else to spend the time finding and putting together parts, but otherwise building a miner is invaluable experience for being successful mining long term.

Build yourself.

Overdue the PSU in wattage and efficiency

Overdue the cooling

Make sure you know what shorting a PCI ex plug involves and then find a motherboard that doesn't require that to get 6cards going. Most immediate ones springing to mind are MSI's Z87 line, the G45, G55, G65 for non shorting requirements.

 

[Z15CAM]

Overdue the cooling

With what 2x's 290X's under water?

Is that a profitable mining rig?

 

[Attic]

More along lines of air movement and or AC solution.

I see a lot of guys have a rig in crate/frame/ect with poor air movement between/under/over the cards. Need to move a lot of hot air away and someone who hasn't built a multi GPU miner before has no idea the amount of heat they'll be dealing with.

Should note that I don't think running gpu fan's at 100% 24/7 is a good solution for managing GPU temps.

I feel like a good solution would be a milk crate sandwiched by box fans. Let the GPUs run on auto.

 

[hondaf17]

Damn. Think I'll just get a used 6950 on ebay for $150. Tinkering around with overclocking it have the GPU clock up to 920 yields a 452 kh/s but it does get up to 85 C.

 

[Attic]

The box fan size i'm used to would be big enough to place behind or in front (depending on natural hot air release from the gpu) and use just one to smash away the hotness. Placement placement placement.

But i'm starting to warm to the idea of the 750ti more and more. Less heat, less watts, for decent hash. My next rig i'll most likely tinker with 4-6 of those.

Maybe one on the top would work.

I excited for what kind of hashing power maxwell will bring.

 

[frowertr]

As bad as Klondike is handled, I can't keep from thinking it might be wise to mine it right now. The diff is low and I think it's only a matter of time before it gets added to Mintpal/Cryptsy/Coins-e. Adding it to any of those three exchanges would bring a spike in prices that would be ripe for a "dump".

 

[geokilla]

I pointed 6 MH/s at Scryptguild for comparison purposes. We'll see if it lives up to the hype...

Any results?
