ThinkComputers has posted pictures of some rather insane crypto-currency mining rigs. If you want to know why AMD GPUs are so expensive right now, this will give you an idea. :eek:

Crypto-Currency mining has really taken off over the past year or so. So much so that we have seen a shortage of AMD graphics cards that are used for mining this currency. There are even motherboards and PC cases made specifically for mining. While many people mining are just using 1-2 graphics cards there some pretty insane setups.

Assuming those are all R9 cards in that pic, I'd hate to see his electric bill. :D Looks like he has around 100 cards.
 
Wow!!! Just think about all the cheap cards that will be for sale when these economies crash!!!!!!!
 
Well considering 100 r9 290x would be around 100 mh/s at that speed he would make about 600-1000 dollars a day he makes more in 2 weeks than I do in a year...

Also the only 2 things that could possibly make video cards cheaper again would be if a asic for scrypt came out and was faster than these video cards for a fraction of the electricity the video cards use. Or if the EU un and us banned the use of cryptocurrency. At this point in the game the us is close to adopting it as a currency as we are slated to have bitcoin ATM distributed in the us tiger direct.com overstock.com and others are accepting it directly...

There is an asic for scrypt, its ~$250 for 330kh/s @ 7w for the 5 chip version (the circle ones). It'll do dual mining also at 300kh/s scrypt and 5gh/s sha256 @ 60w, but that's pretty crap when compared to most sha256 asics.
 
So which currency is looking to be the next big up and comer?
Could anyone possibly message me what they believe is a good synopsis of what's going on in the current market? I am out of touch - completely it feels...?
 
Just to clear up some confusion, this thread is linked to the front page and is not in the Front Page News forum. For anyone (like me) that didn't realize at first.

Crashes don't matter, as long as tehre is the next cryptocurrency. The more interesting thing will be how awesome will the r9 cards be as soon as the revision comes out that mines a bit more efficiently.
 
That's a sick setup. AMD does build some nice cards for doing other things than game on.
 
If I ran that in the UK, chances are I'd get raided for running a pot farm!

Either the power company would tip off the cops or the police helicopter would pick up the heat scan.
 
Dumb question. House hold breakers are 15 amp which means about 1500watts per room unless you are weird and have multiple breakers per room. So how the hell are these people even running these things? Even if it was 1 breaker per 6 card 1200 watt setup, some of these rigs are 100+ cards in a room. An old house has a 100 amp service, a new house has a 200 amp service. So how the hell are they wiring these things?

I'm sure there's some creative and not so creative solutions. On one extreme I'm sure, in some cases, you can have more power service installed. On the other end I wouldn't be surprised if some of these people are installing bigger breakers and running extension cords all over. A lot of solid wiring can handle 20A but it obviously increases fire risk if there's a fault/weakness somewhere. I've put 20A loads through 15A extension cords a couple times and it works ok. It's not really good for the equipment either to do that.

This is slightly off-topic but related, I think. I had a neighbor down in FL who bragged his electricity bill was low. It was found after some investigation that he jacked into his neighbors electrical system. I'm thinking some of these miners are doing the same. :D

Automatic coin hopping pools that quickly switch to the most profitable altcoin at any given second. this has forced the wide adoption in altcoin code of the "gravity well" dynamic difficulty adjusting algorithm. Coins to watch in the alt space;

LTC (of course)
DOGE (I am as bewildered by this as anyone)
Zerocoin (the actually anonymous BTC fork)
Megacoin (the innovator that brought the gravity well to the scene)

and to a lesser degree

FRY, GLC, KDC, LEAF, LOT, MEOW, NOBL, SBC, SMC

I can't wait for all the cheap CPUs that will flood the market when the fiat ponzi scheme crashes and the stock markets close.
 
I was thinking about the electricity load as well. But if you can tap into the main breaker (power company/house one) and with a little electrical engineering knowlege, you can build a fairly high current "new" break to supply a very high load. If you are willing to drop $50k on these cards alone, then im sure cracking open that main breaker is nothing. Now what happens is when AMD releases the next GPU that will do 1.5 Mh/s....cheap upgrades for us all!

economies will not crash, there will always be some sort of mining to do. Its more of doing it efficiently rather than availibility.

I dunno, what condition are these cards going to be in after running at 90c 24 hours a day, 7 days a week? I wouldn't touch one.

they dont run them at 90c that causes hw errors i keep mine at 70c or lower... It is hard to say people think their used shit is solid gold so likely they will be priced what new cards msrp for instead of half or less than half msrp. And there are people who argue that the only wear is on the fan it is a perfectly good card but my thoughts are if im picking up a r9 290x, 7950, 7970 or 7990 for 300 i don't care if they mined on it as long as it is fully functional.

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).
 
My cards hover around 72-74c, about 30-40% on fans. Stacked on an open air rack ~ 5 inch apart, 14 cards to a shelf, with box fans blowing on them. I've run my GTX460's harder doing BOINC and Folding@Home since they launched at 100% fan speed. Just recently replaced the HSF on them, just because I felt like it.

Oh and 15A is 15x120V which is 1800W
Click to expand...

A breaker will blow in 4 hours at rated capacity. And i was accounting for droop and the power supply. Doesnt really matter since you cant run 2 riggs off of 1 breaker anyway.

I wish i had 120v, im 108-130 depending on the time of year...:(
 
ViperGrendal said:
I just wanted to add after thinking about it, house service is 240V and a lot of power supplies can run 240v. If you had a 60A 240V source that's 14KW. Some home pools/spas are wired for just that.
Click to expand...

Guess if you disconnected your pool heater and knew how to convert 4 gauge 240 to 10 outlets you could run say 80 cards...

That brings up another problem, can you imagine dissipating 14kw of heat with just some box fans etc.

I was wondering when one of these comments would show up. "I have no idea what i am talking about so i will assume its a scam and know that they will crash!"
 
So, the previous poster's question got me curious about electric power source, and I found this on SCE.com (my power company here in Southern California):
https://www.sce.com/NR/sc3/tm2/pdf/1346-E.pdf

Southern California Edison Company (SCE) hereby transmits for filing the
following changes in its tariff schedules. The revised tariff sheets are listed on
Attachment A and are attached hereto.

PURPOSE

This advice filing revises Section B.4.d. of Rule 2, Description of Service, to increase
the maximum breaker size allowed for 120/208 single-phase service from 100 amps
to 200 amps.
Click to expand...
So, technically, all homes here in California should be 200 amperes since this proposal in 1998. The household owner would only need to upgrade their circuit breaker box to handle it if they aren't already.

Maybe something like this:
http://www.homedepot.com/p/Square-D...-Load-Center-with-Cover-QO160M200PC/204246798

$354.00 from Home Depot.

Then, install these: 20-amp circuit breaker for each circuit/outlet of your house.
http://www.homedepot.com/p/Square-D...-Single-Pole-Circuit-Breaker-HOM120/100045009

And, install these: 20-amp GFCI electrical outlet
http://www.homedepot.com/p/Leviton-...I-Duplex-Outlet-White-R02-N7899-0KW/203427638

20A x 120V = 2400W per outlet

Assuming 6 cards maximum per motherboard and 6 R9 290X video cards using two power supplies (3 cards per 1300W PSU*) using an AMD Sempron 145 and a cheap AMD 970 board, we're needing two separate outlets to power this. (2600W > 2400W per 20A outlet, so separate outlets.)

* Antec 1300W PSU - $334.99 (Gold Award from HardOCP).

So, let's see... let's go with an even number of 36x R9 290X ($598.55 each)-- $21,547.80 total (before tax and shipping).

That'll be 3 cards per outlet, thus need 12x 20A outlets at $16 each-- $192.

And, 12x 20A circuit breakers-- $42.

Add, $354 for the new panel plus electrician installation (if you're not the do-it-yourself type or a licensed electrician...) and rewiring since 20A requires a different kind of wire-- 10- or 12- gauge, and we're probably looking at maybe $2500 average for my area, $2900 including the new main breaker panel.

Total costs:
Computer + video cards = $27,218
Miscellaneous parts (PCI-E risers, shelves, etc.) = $300 (?) (rough "guess-timate")

Main breaker panel, installation, and re-wiring = $2,900
Outlets + circuit breakers = $234

Total = $30,652 (tax, shipping and other miscellaneous costs not included/factored)

​
Let's assume 830 kH/s per 290X, so 36 x 830 = 29,880 kH/s

At the current Litecoin value-- $15.46/LTC-- and difficulty-- 3206.904, we get 281.15 LTC a month, or $4346.58 a month. (Using the calculator from WeMineLTC.com.)

That person will have paid off the $30,652 investment in 7.05 months.

In one year, that person would earn $52,159. Subtracting the initial investment, it'll be $21,507 in pure profit. Adding another month or two and he/she could set up a second group of 36x R9 290X cards and earn nearly $9000 a month if LTC value holds at $15 to $16 per LTC, or $108.000 in one year.

Converting the LTC to BTC, that's 7.08 BTC a month. (Using BTC-E.) Selling that would be $4,311.72 a month from BTC if using BTC-E.

So you want everyone to lose money because?

1.you are jealous that you missed the boat to make a lot of money quick
or
2. You are butthurt because online retailers spiked the prices of GPU's due to influx in november-december last year. Ever heard of supply VS demand?

Aw look, the haters are out being all jealous and talking shit. How cute.

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.
 
I forgot to factor in the electric bill.

With 12x 1300W PSUs (3 per card) at 24 hours per day usage, we get 374.4 kWh.

At my current average kWh rate from SCE of $0.16/kWh (Tier 2), we're looking at roughly $1800/month in electrical bills before taxes and any other fees SCE wishes to charge me.

So, let's say $2000 to even it out. Profit per month becomes $2346.58.

The person would have paid off the investment in about 13 months. After that, it'll be $28,158.96 per year after electric bills are factored in.

What will you do with an extra $2346.58 a month (or $28.158.96 a year)?

Yeah those are not fully on the market yet.

each gridseed chip does 70kh they have a couple packaged miners around the 300kh/s mark each and they also do sha-256 at the same time so 60kh scrypt plus 1.6mh/s sha-256 per chip most come with 5 chips and are sold in lots of 10 all are based off the gridseed chip.

Gridseed GC3355 X 5
5 * 70 kh/s = 350 kh/s * 10 = 3.5 mh/s @ 5 * 5w = 25w * 10 = 250w

But few of them have been delivered and as far as i know they are in a holding pattern of not quite on the market yet...

also the price is 2205 plus import tax per lot of 10

plus most alt coins have code to protect against asic...

290 series are bad for mining,

the best are 280x and 270x (7950 if u can find them as well)

a 280x and 270x setup will break even in around 4 month in LTC.

i am currently at 14 MHash, and i'll be adding 6 r280x soon to come up to 18 Mhash.

i am using servers PSUs to being down the cost.

if u go with 1200w PSUs plus they will cost u a fortune.
