[OPEN] R20x: LTC/ALT Ultra Power Rig GB! $212 = 144-160 KH/s + DZ MC Exclusives

[Damnsammit]

7850 for $200 makes 400kh/s...

That's my thoughts as well...

I just got a 5850 on Craigslist for $60 and it's hashing at 330kh/s

But, with the group buy you don't have to factor in any time spent doing maintenence and the cost of electricity, riser cables, PSU cables, PSU/mobo/cpu/ram/etc (if you are out of PCIE slots), so I could easily see this being a good venture for someone who just wanted to get into Litecoins but didn't want to build a mining rig from scratch and doesn't have any PCIE slots lying idle.

You're asking for over $5300 for a 4kh machine?  Wow.

assuming high prices:
6x r9 280x @ 450/ea = $2700
Mobo, risers, cpu, ram = $350
1250w PSU x 2 = $600
3kw generator = $800
2000Va UPS (~30m+ uptime on a 2kw draw) = $800
Misc costs = $50

Total: $5300

I guess this makes sense...

Just pointing out the costs that would have to be associated to justify such a high cost per share.

Also... "Your share price includes acquisition of.... [USP and generator]"
This implies that they don't have that equipment yet, and besides, that equipment can't be shared if spec'd at the stated output.

Regardless, this seems to be very overpriced, but to each their own.

i'm considering getting 3 shares but it seems like such a big risk. in a month the difficulty will probably at least double.
at that rate (diff 5000+), 500KHS will get you 0.6 LTC a week.
but as we see, at the current rate of craze for litecoin, the difficulty bounces up 3 times in 10 days... and the leaps seem to be getting bigger and bigger.

as of right now, for that same price (roughly 0.6B for 3 shares) i can buy 16.6 LTC.

not trying to knock anyone down or anything, but something really crazy has to happen to the litecoin price in order to ROI on this, and with the current difficulties BTC is having i really can't see that happening easy just like that.

i'll keep monitoring but no buying as of yet.

but a huge thanks for even considering this, love you guys!

1 share = $212 = 144-160 KH/s for 6 months


you can buy a used 5870 or 6950... for and get double that at least.....

[DyslexicZombei]

Yeah, guys I love you but the economics on this are way off unless LTC goes through the roof.  Going to have to pass on this one.

well if it is 25 shares for a rig . you pay 12 bucks over head 300/25 if the share earns 50 bucks - 12 = 38 dollars back in 1 month .  at todays  difficulty .   ltc does go up and down in diff.  I won't decide until r9-r12 gets settled. if I get a buyout and divs I would buy a share here maybe 2.  I am certainly liking r17 more.   but remember this machine will sell for parts as it has great gpus inside of it. so it will have value even if all mining dies.    when I cashed in all my pc gear I sold 21 gpu's for over 4k.

The problem is that it will be tough to get ROI on just the shares.  You raise a good point the hardware itself in 6 months will be worth nearly 80% of their costs, because you can sell the hardware to just about anyone, and the hardware in question will still be top contenders in 6 months.

I just wish there was an easier LTC exchange to deal with the current options are pretty much horrible.  The only reason I would take part, would be to bank some LTC, and then get some of the BTC back when the hardware is sold.

no doubt roi on the mining alone almost certainly won't happen in ltc terms but maybe it could in usd.   but I am thinking you always can get 70 to 80 percent back on the pc/gpu aspect.  so this would not ever really zero out .  it is a different  mindset to invest in this.

that is why I want 1 share at worst 2 or 3 if I get a r9-r12 buyout.

This group buy doesn't seem like it's the same as the other rounds.  It looks like it is a 6 month mining contract.  Maybe I'm missing something, unless the coop votes to sell the equipment, there is no recouping the cost of the equipment.  A LTC miner can keep hashing much longer than 6 months and stay profitable.

Also, $300 a month for hosting is extremely expensive.  That is going to be a very large percentage of the earnings.  Hosting for the ASICs makes up only a small portion of earnings, that is why it's a great deal.  When hosting makes up more than 10% of the earnings, I say it's way to high.  As of today, running at 4 MH, it would take 6 days of mining to pay for the $300 a month hosting fee.  That is around 20% of the total earnings.

Valid points:

- the 6 month date is to re-assess things, we'll just continue mining if it appears to continue to be profitable, or we'll sell the rig to help recoup costs.
- these rigs are rated for up to 2.4-3 Kilowatts, so there's a *lot* of power (and noise) involved with running a quad GPU miner. There's also fans, and A/C to consider.

Also: there is labor/testing built into the price. This is different from other GBs as we're building our own custom, high performance Scrypt rigs for us to use and need to include a fair price for professionally insured, custom built, high end Scrypt rigs.

This allows us to sidestep/hedge against hardware shortages in the ASIC world (near term Bitcoin hashrate is still in short supply) and expand ALT mining ops as needed.

** We will be doing multipool, even multi-coin mining. I listed this as an LTC GB but we will definitely be mining some of the better known ALT coins when it makes sense, as we're big fans of triangular arbitrage **

Yes, you could. A used card, that may or may have not been beat to sh!t and overclocked to near death (because the owner only cared about selling the hardware before it failed as all stressed components tend to do prematurely)...

...which also assumes that you have an entire rig you either paid for, or you bought a whole new rig for, and that you and your housemates don't mind the noise/heat/cooling & power costs.

I went into this issue further when the forums were down: http://www.reddit.com/r/dzminercoop/comments/1soze8/about_our_new_ltc_rigs_and_group_buys.

This GB is for those that want to get into LTC/ALT mining, but don't want to build a rig, buy a rig, or deal with the noise/heat/cooling/power costs of a GPU rig or farm.

Like you: I could easily build this rig myself (and deal with all the inevitable cuts and scrapes). This GB wasn't really meant for you or me. However, OTOH: my wife would def. not be ok, with a 2 or 4 GPU beast running in the house and driving up our electricity costs (about 50 cents a Kilowatt hour here).

We're actually building Facility #2 (we maxed out Facility #1), which needs its own gas generators and Server grade UPS units with battery banks, and additional A/C installation.

These are high end, custom built machines, assembled and tested in 'Murica. We're only going to sell and host/ship, the best of the rigs (and will hold sub-standard ones aside to address later). Our prices are very competitive with what you would get from a custom rig builder such as Puget Systems, except that we're more focuses on the mining side.

AFAIK: we're the only sales outlet that are offering custom built to order R9 LTC/Alt rigs at this time.

- One more thing: instead of closed cases, we may use open cases that can fit 2 mobos and up to 8 GPUs, if there's enough stock available.

There is a litecoin project you guys might actually be interested that's right up your alley. Jaisonlee from these  forums is involved they are ready to go live soon.

Cool! Thanks bitterdog. I'll check it out, as that's definitely up our alley. There's a number of companies attempting to bring ASICs and FPGAs to the Scrypt market; it's like Bitcoin ASICs Gen1 all over again, except with Scrypt. I'm keeping an eye on this space to see who has a shot of making it.

Who knows who will win and who will not even make it to market. All I know is that whoever launches real hardware will have ASIC or FPGA Scrypt hardware that we'll likely sell.

BTW: I've always appreciated your input and your objective, even handedness.

Cheers!

Yeh do a knc, up the spec at the last minute.

[madpoet]

I guess the thing is guys that building a 6 GPU litecoin rig with 280s costs something like $2600.  That's ~4500 hash rate.  Assume $5/day for power which is pretty accurate.  That's $150/month for power.  Cooling is a $10 box fan   I get that there is overhead because of hosting fees, and I get that you want to make a profit.  But your rig cost is almost double what I would expect.  That's where I'm struggling.

[wpgdeez]

I'm running 10 7970's and am making way more money of sexcoin than LTC. I just bought 4 more 290's. 280's are a way better deal if you can find them. Running rigs does make a lot of noise and heat but if you can handle that you will come ahead in the end over this GB and will have hardware you own that you can resell and you don't have to rely on anyone else or vote on when you sell what you do etc.

I think DZ has a lot going on and am wondering when they will start getting in over their heads if they aren't already.

I read all the numbers and I said I have to try to get my leftover btc rig mining ltc.  so after 34-40 hours of trying to make it work.  I am pulling 650khs with a hd7970 rig can add a second card  I HAVE A HD7790 I will pop it in and get the rig to 1k.  Now that it is cold in New Jersey running a pc pulling 300-450 watts helps to warm the house.  If it was not for this thread I never would have got the rig to run ltc. My Thanks  to dZcoop.   Making money for me in all kinds of ways.  next i need to figure the lit coin block chain wallet out as it is a bit different then the btc chain.   I am earning about .3 ltc a day with 650  kh running.

Good to hear that you doing well. I may build my own system to play with

[philipma1957]

yeah it is a real pain to find a cgminer + catalyst combo for your card.  they vary.

 I have cgminger 2.8.3 with catalyst 13.11 running the sapphire with windows 7 ultimate and an asus maximus gene.

    but if you put in another card it may or may not work.

[wpgdeez]

You make it sound way harder than it is. I can build a rig from scratch in 2 hours including os load with steady hash rate no cuts, scrapes are any of the other FUD.

[testerx]

This makes no sense financially and if it's going to be hosted in a data center it should be using specialized GPU mining racks that can run more GPUs per motherboard/CPU.  You really need open racks and to use PCI-E riser ribbons if you want to build a GPU mining rig, using a desktop computer case makes no sense especially because heat is a huge issue with scrypt mining.  Also to be honest, scrypt mining is VERY finicky compared to SHA256 mining, you're talking about constant lockups and crashes if heat isn't perfectly controlled.  The amount of time that's going to go into keeping everything running is going to be much higher than with bitcoins and given how the Bitfury towers already caused a ton of problems I'm not sure the coop has enough manpower to keep racks of scrypt miners up and running.

Using what cards?  I find it is a pain in the ass sometimes trying to get different cards working together.  I had a 5830, 2x5850, and a 6950 in my rig and I had to try a lot of different versions of Catalyst and cgminer before they all wanted to work properly.

Then I tore that apart and am using 4x5850s and working on getting the parts for my other rig... put the 6950 in my sons computer so he can play stupid FFXIV
