Cryptocoin Mining?

[geokilla]

Just as an update/FYI, I have now found some pretty good settings for my PowerColor 7790 (factory clocks: 1030 GPU, 1500 VRAM). I'm getting a little over 245Kh/s with:

--thread-concurrency 8000
--gpu-engine 850
-I 18
-w 128
-g 1

And it's running cooler now (68C instead of 72C at stock speeds). So the "set GPU speed to ~.57 of memory speed" mantra can actually hold true. Funny how I misunderstood this advice before; I guess I was thinking there was no way that underclocking my GPU would help. I was getting ~220Kh/s at the stock 1030MHz clock speeds.

Wish I knew where my Kill-a-watt was, but this thing is supposed to pull ~100W max IIRC. I picked it up on Newegg during Black Friday sales for $90. Would have been $70 if I had mailed in the damn rebate in a timely manner...

Wait so what speeds and hash was it before and what's it now? Both before and after is still 1030MHz GPU core.

Just to put out some numbers:

Assume the mining computer uses 300 watts, you leave it on constantly (24 hrs a day) and your electricity costs 7 cents a KWh. Your computer would cost $183.96 per year in electricity alone, so you could mine constantly for 1.63 years before spending $300.

I'm not sure how much a 7970 could make if mining constantly for one year and eight months, but it may not recoup all $300 in that time based on diminishing returns. It's just pretty crazy that some people have made like $300 in a month using a 7970 way back when before the difficulty increase, and the electricity would have only cost about $15 per month.

Everyone's power cost and equipment is different, but the average USA electricity price was 12.31 cents/kWh as of Oct. 2013 (it's probably a little higher now, as you can see from the trends in the link below). A 7970 oc'd to 700 kH/s with typical rig components (CPU, mobo, RAM, PSU, drives, optical drives, etc.) eats more like 325 watts at the wall. So by those numbers which are more realistic than dirt-cheap 7 cents/kWh prices, a 7970 rig would eat slightly over 96 cents/day, taking 312 days to eat $300 worth of electricity.

In actuality, that 7970 will eat $300 in electricity even faster for people who live in jurisdictions that have tiered electric rates. Tiering means the more you use, the more you pay. For instance in the SF Bay Area you are given a paltry base amount of kWh in the first two tiers of electricity usage. If you stay within that range you pay about 15 cents/kWh (there isn't much difference between the first two tiers' prices). But the moment you go above that range, you pay 35+ cents/kWh. The MARGINAL electric rate is really what you want when computing mining costs--you want to compare what your electric bill would have been without mining, and compare it to what it is if you do mine.

Anyway the exact amount of time it takes a card to eat its cost in electricity doesn't matter for the purposes of my post, which was that the GridSeed Scrypt ASICs are roughly 6 times more energy-efficient than current video cards like the 7970. That's why people are willing to pay a premium for ASICs. Obviously if you have free power you would be less interested in an ASIC.

I thought the "--gpu-core 850" switch set it to 850MHz? ~245k with 850 setting, ~220k at stock 1030. Memory stays stock at 1500. I tried messing with it a bit, but it seemed to get unstable.

EDIT: Oops, I meant --gpu-engine, not --gpu-core.

WTF?

I got more with a higher core. Remove the --gpu-core setting.

When I had my Asus 7790s, I underclocked both GPU core and VRAM in order to get it to 250kH/s. Overclocking it certainly did not help at all with the hashrates. I returned them for a refund even though they were $70 each after $40 MIR (limit 2) because at 250kH/s, it's pretty much a waste of a PCI-e slot.

I meant --gpu-engine, not --gpu-core. In any case, I played around with it a lot, and if I got above ~900 then my hash rate went down by about 20kh/s. Just for grins, I took out the setting just now, and it's sitting at ~220.

What's their payout now? Does anyone have numbers (hashes to bitcoins)?

I've been getting about 0.015 BTC every couple of days on ~1.3 - 1.4 mh/s. I wasn't on middlecoin 24/7 however as I switched between different coins..

My first payout was Jan 8 and I've been paid 0.06 BTC so far over 4 payments.

 

[holden j caufield]

Currently mining Doge. I get about .8 LTC a day with a 2.2m/h setup. That's when they aren't going down, losing connection with the stratum/pool (which is 95% of failures).

Is Doge still that profitable? I got ripped off at some pools, and some kept going down so I've been away since they dropped. I've got about 4mhash now and it's only worth about 1 LTC a day.

I know value has gone down significantly, but, between November and December last year with mining LTC & DOGE using 1.8 mhash I cleared a BTC per month.

Definitely can't do that now with my hash rate though it seems.

What pool you mining at? I have 3.2 Mh/s and based on Coinwarz it's pretty close to what I get mining just Doge

I'd get ~.5 LTC/daily if I went with wemineltc... just a guess, but that seems about right. I use fast-pool.com which seems* legit. I thought netcodepool was legit, which I still think they are, but they got hacked. So once I get my paltry stash off there I honestly don't care as I setup daily cashouts. Doge has surged in popularity and value because Coinye was a complete let down. Though I wonder if it will come back. I've a few coins so we will see..... just check coinedup.com for current values.

as stated above, fast-pool. silverforce (who posts here quite a bit) recommended it to me. coinwarz is bogus. don't trust it....it's metrics don't value daily value, which is what matters. Plus the multipool miners (like middlecoin) really fuck everything up. just saying: don't trust it. you will see what I mean if check it over time while actually mining/trading.

 

[UNhooked]

I mine at fast pool but noticed 3 deposits to unknown addys. It was about 30K doge so wasn't alot.

I quickly changed my pwd and have been good since.

I just wish they had lower payout threshold. 10K is too much for me to keep it at a pool.

 

[slashbinslashbash]

dogehouse has auto payout at 500 doge minimum. Has been quite stable for me and one of the larger doge pools, often at 20%-30% of the net hashrate (currently at 7.18GH/s out of 35.96).

 

[taltamir]

why would you use anything but largest pool?
The larger the pool the more collective hashpower it has, the more likely it is to get a nonstale. Pools compete not cooperate.

Except for 51% attacks, so don't pile in the same pool as half of the miners. Spread out the hashpower but yes, definitively use one of the pools with 10% or more hashpower.

Yeah coinwarz is touchy since it tells you estimated values based on the value of coins and their difficulties at this very moment. However, you can follow the history to get an idea, plus watch what's consistent. Some of the bum coins keep hopping to the top with each pump and dump but after the dump they are back on the bottom. Basically you have to be vigilant.

About the dogecoin pools, definitely switch pools. Some pools lose members to the other coins and to more profitable coins. The bigger pools will have a couple percent of rejections, not 95%! I think it has changed since the inception and you have to check the statistics now and then.

Heh...

Very news: Much trade.
Dogecoin, "an open source peer-to-peer cryptocurrency, favored by Shiba Inus worldwide" now accounts for more transaction volume than every other cryptocurrency combined, including Bitcoin, Litecoin and Quarkcoin.


In other words, I'ma let you finish but dogecoin is the most-transferred cryptocurrency of all time (sorry Coinye).

One bitcoin is worth around $825 as of Jan. 14. One dogecoin is worth $0.00031, or basically nothing. The total market capitalization of all bitcoins is over $10 billion, while the total worth of all dogecoins is over $9 million.
While there's 12.25 million or so bitcoins, there's ... um ... 27 billion dogecoins. The average bitcoin transfer is worth $9,339, while dogecoin hovers in around $105.80.
In other words, bitcoin is being used for big boy purchases and large-scale transfers, while dogecoin is primarily being used to transfer small amounts of money around the world. The dogecoin subreddit even has a bot that randomly hands out 100 dogecoins to users or instantly transfers them between users at their discretion.
So what's it useful for? Mostly fun! According to Spelunk.in's Pinguino, "dogecoin is very very silly, and very fun. Currently, people are mostly buying Steam games and the like with it."

In order for a 51% attack to occur, over 50% (50.000001% counts too) of hashing power has to come from an individual or group who is cooperating in using a modified client that is meant to perform something illicit (either double charge, or reject the other 49% of the network's hashing, in effect stealing new coins as they are hashed from the other 49$)

If random pool X gets to 51% hashing power with random individuals who each use the default unmodified client then it won't be a 51% attack and nothing bad will happen.

coinwarz is useless since it only tells me the value based on crypsy and everyone says that that site is crap, it is full of technical issues which in effect means you will not be able to sell your coins in a timely manner, expect to lose a lot of money.

Coinwarz flips to vicurex too, I think it has a backup if cryptsy hasn't responded or if the vicurex data is fresher. Is there are better exchange then cryptsy?

Cryptsy works fine, it seems a little slower at certain times.

I think people have problems, perhaps understanding that if they try sell coins, it works with a queue.

Say there's a buy order with 5 BTC, when you put a buy order in at the same exchange rate, it will sell the 5 BTC first and then yours. People miss out if they come to the end of the line and the course changes direction (which happens frequently with doge at least). Just because it hits your exchange rate doesn't mean your coins sell, until the queue in front of you empties. I found it to work well for the very little I've tried.

I don't know yet, its on my agenda to research this subject properly.
There are far far far too many scams out there.

 

[wand3r3r]

For those of you dabbling in NXT coin which requires a Java Runtime Environment (JRE).

I'd keep my wallets somewhere else than on the machine with Java, and keep the JRE up-to-date.

I've traded a lot of altcoins (as well as LTC) on CoinedUp since early December. No trade fees and no problems beyond the occasional downtime. That's not to say they won't go tits up at some point, but for now it's my favored exchange.

One concern there is the live id, there was at least a claim that a user had identical id's due to the open id and their acct. was emptied. There are plenty of risks at any exchange, particularly the smaller ones. They seem to work, however I wouldn't "store" large sums there.

Login auth is through Google OpenID. I created a unique username and password specifically for that purpose and have never had any issues.

 

[slashbinslashbash]

I would not "store" any amount of coins on any exchange, pool or other third party. Once I'm done exchanging, everything's back to my wallets. I do not doubt the honesty of most of these sites, but I do doubt their security. Nobody's perfect, and there are some very intelligent and determined hackers out there.

It's like the old saw about robbers and banks; Why do the hackers attack the pools and exchanges? Because that's where the coins are.
