A closed case will need very powerful fans, drawing a lot of power, decreasing global efficiency.

Yep. Closed case > small space for airflow > needs more pressure.

8 chassis cooling fans that are 24W each

So I've been browsing around graphics cards, it's become apparent some manufacturers will use more power for the same clocks of the same make/model of card as another manufacturer.

Say a Asus 970 clocked at the same speed as a Gigabyte 970, the Gigabyte will use more power.

Is there anyway to figure out what card uses more power without actually testing it yourself? I noticed the power connectors are not the same across all cards in the same make and model. However, I have noticed that this isn't always a direct correlation to the power draw either. This can vary wildly too.

For instance some of the 960s have a six pin, others have a eight pin, and still others have two six pins. I don't know if this means a double six pin will pull infinitely more power then a single six pin, but it would hint at it. It could be the single six pins just don't have the right amount of power connectors for the maximum draw as well.

Look into the BIOS of the card from here or do your own tests to see efficiency.

Other than that, PCIE-E 1X can output 10 watts, PCI-E16x can output 75W, 6-pin can do 75W and 8-pin can do 150W.

2884  Alternate cryptocurrencies / Altcoin Discussion / Re: Litecoin halving is near, will the price increase after halving? on: July 23, 2015, 09:51:15 PM
Pretty much everybody expects the halving so I think people overvalue the immediate significance of it so it likely won't increase much.

From another perspective, every single day there are roughly 389 BTC worth of LTC being mined. But considering the daily volume (at the moment) is 16178 BTC or $4.5million , it's safe to say that even if that 389 BTC worth of LTC would get dumped everyday, the market could easily soak that up without it having any effect on the price. So halving that 389 BTC will only have any significant effect on the price is a physiological psychological one if people en masse fail to realise the math behind what I just pointed out.

Edit: typo
Fair enough.
However, don't you you think that the volum  will decrease ~1 month after halving? Since the  supply is decreasing, thwre has to be some fluctuation if not a major one.

With the numbers from my quoted post the number of coins that won't be mined anymore after the halving amounts for 1.2% of the daily traded volume. The volume at the time of writing this is 7890 BTC which turns the same number into 2.46%.
So while the volume fluctuates a lot, I think a conclusion can be drawn; the halving should have a negligible effect.

However, I think the price will change a lot more than that but mostly because of psychological reasons and market manipulation.

I personally don't hold LTC as I think it's too scary to invest in it because it seems its market is heavily manipulated so while people are accumulating LTC and waiting for a prince increase, the whales might exploit that so we might see a price decrease.

I'm curious to see what will happen though.

Personally I think anything GPU-based for fair distribution as not everybody have ASICs or botnets (CPU):

x11, x13, x14, x15, x17, jackpot, qubit, nist5, fresh, groestl, myr-groestl, quark, luffa, m7, blake (any), keccak (sha-3), heavy/hefty1, fugue256, deep, s3, spread, dmd-groestl, lyra2RE, pluck, whirl (any), zr5, skein (any), yescrypt, scrypt-jane, etc...
2886  Alternate cryptocurrencies / Altcoin Discussion / Re: How soon will Monero market cap pass XCoin/DarkCoin/DASH? on: July 21, 2015, 11:46:41 PM
Useless? I don't think so. Market cap is fundamental number.

And what way is it helpful other than one being bigger than the other must mean it's a better coin?

I could create a coin with billions of coins per block and setup a bot to buy a couple of them at 1 sat/coin so I'd have a coin with as high marketcap as bitcoin. Would that be representative about the health/quality/popularity of the coin? No. Volume can be manipualted as well but it is a bit useful while marketcap specifically in crypto I think is completely useless and people overestimate it for no reason.

If you have high marketcap but low volume, it doesn't matter how much all the coins would worth with the snapshot of the current price because low average volume means the market is weak and the price of the coin can be easily manipulated. Which is what marketcap is based on - current price.

But if you only look at volume you can get an idea about the health of the market.

Marketcap is a useless number in crypto. Volume is more representative.

5.6MHASH@38W. Low clockspeed/memory speed




Is this a particular 750ti that has such low wattage? Is there some way to find these specific models? Some people in here were reporting like 68w.

Also 750tis have ridiculous overhead as far as systems go, but given that efficiency is almost double the 970s, that's a eyebrow raiser.

I've said this before and say I say it again; software reported power consumption numbers cannot be trusted.
The smi reported 38, 45, 46 watt cap figures are not representative of how much the cards can pull regardless of having a 6-pin or not.

If Sp_'s SMI figures were correct the 750 Ti would be 48% more efficient than a 970. That is laughable. That would be 6.78 W per mhs for the 750 Ti and 10.06 W per mhs for the 970 (to be fair the 157 W is a low fluctuation and the 970 is using slightly more on average so it has lower efficiency or higher W/mhs).

750 Ti's without 6-pin, with stock speeds and unmodified BIOS with release 55 are using 57.5 watt per card which is a measured figure while SMI is showing 38W. The real and measured efficiency of the 750 Ti is therefore 10.26 watts per mhs which is more in line with the 970 as expected.

Use a kill-a-watt or a multimeter or a UPS that reports power consumption but do not take software reported figures for granted.

2890  Alternate cryptocurrencies / Altcoin Discussion / Re: Preventing Botnet Mining on: July 21, 2015, 01:45:07 AM
When I read about ASIC resistant mining, it's pointed out that botnets can be used to mine the coin. Could adding something like CAPTCHA prevent botnets from mining?  Is there any ASIC resistant mining that already takes into account botnets?  We shouldn't give up ASIC resistant mining simply because of botnets, that's a cop-out answer.

I think that ASIC resistance is extremely important, as it lowers the barrier to securing the currency, giving all an equal ability to mine, not just the few elite.  There has to be a solution to botnets.

Monero making solution smart mining. Many more members mining reduce impact of botnet hashrate

https://forum.getmonero.org/1/news-and-announcements/112/monday-monero-missives-20-december-8th-2014

"This is a feature that will evolve over time, but at its most basic it is something that will allow everyone running the client software to support the network in an unobtrusive manner. Smart Mining detects your CPU usage, and if your CPU is idle and you aren't on battery power (for laptops and/or connected UPS devices) it will begin mining. As soon you switch to battery power or your CPU activity picks up it will pause mining until it sees it is safe to start again. You still set your Monero address for Smart Mining, as always, and whilst your chances of solving a block may be relatively small (for now;) it is still an easy way to support the network without needing to purchase expensive equipment. This work is complete (for Linux) and is currently being tweaked to work on our other supported operating systems. Ongoing process can be followed here: https://github.com/oranjuice/bitmonero/tree/smart-mining"


That doesn't sound like a solution to preventing botnets from mining.  I'm wondering about ways to authenticate a miner using some form of human input, like a captcha does for the web.  To start mining, you have to verify that you are a human doing it.  If someone has hacked a bunch of computers, they must first get the user to preform an action before the mining network will let them mine.  This would prevent a botnet from hiding in the background of a hacked computer, mining away.  Something along these lines is what I'm wondering about.

As I said botnet owners generally point the infected computers towards their stratum proxy. So potentially thousands of infected computers connect to one point which can be pointed at any pool as a single connection like if you were to rent rigs on miningrigrentals that also redirects the rented hashrate. So for all the computers in a botnet only one captcha would be needed by the botnet/proxy owner.

Unless you create a pool which only allows a custom miner to connect with that has a captcha built into it. But why would anyone use that? And even if there was an incentive to use such a miner, people would eventually hack the miner so that it wouldn't require captcha or that it could be used on a normal pool.

Depending on which group of miners you want to favor, I think the best bet would be if coins would use algos that are the fastest on GPUs, very slow on CPUs and there's no ASIC yet.
I'd imagine the vast majority of infected computers only have 1 mediocre CPU and 1 mediocre GPU while mining rigs have 1 weak CPU and 6 powerful GPUs so a GPU friendly algo might make the biggest difference.
2891  Alternate cryptocurrencies / Altcoin Discussion / Re: Preventing Botnet Mining on: July 20, 2015, 10:20:05 PM
Botnets can mine anything, ASIC resistance have nothing to with it. It's just happens that ASIC coins are the least profitable for CPU/GPU botnets for obvious reasons.
And botnets usually going through a proxy so the pool has no way of knowing if a miner is a botnet or just a GPU farm as they can only see one connection from coming the proxy.

I also don't see how monero smart mining is a solution as most botnets work the exact same way to try hide themselves from the owners of the infected computers.
Most algorithms are also unprofitable to mine with CPU's if you have to pay for your electricity (unlike botnets) so deliberately mining with more CPU's and therefore wasting more electricity in order to somewhat offset botnets is a borderline retarded idea.


Smart Mining is kinda a solution as it could make the mining less profitable, so the botnet or some botnets may find another thing to get money from.

By deliberately wasting electricity with CPU's in order to increase the difficulty a bit? Who would do that? If that would have any effect, botnets would just mine something else like Lyra2RE as they seem to do now.
But as soon as the difficulty would drop or the price would increase they would be back at it again. Besides, making mining less profitable also decreases the network hashrate which is not ideal.


Well if it would have an effect, maybe other coins would follow making everything less profitable, so the Botnet may switch away from coins at all.

Decreased profitability would also mean higher centralization since only the big farms with cheap electricity could continue mining with a profit and the average joes with small to medium farms with above average or even average electricity prices would have to eventually stop mining which would mean less hashrate, less nodes, less network security and less people involved.

Dogecoin was very popular at the end of the last year.
And a bit in the early this year (2015)
Current market cap of the doge is $ 16,870,438 which is pretty good
From all conis it is the 5th after DASH and before Stellar was a pretty coin too.

Dogecoin really?

C`mon guys there are 100 billion of it and still growing, its a hyperinflated fiat dogturd, it doesnt even resemble the traits of a cryptocurrency.

I don't get why and how doge is still relevant but I don't think instamined dash is any better.
2900  Alternate cryptocurrencies / Altcoin Discussion / Re: The Dogecoin, Dash bout on: July 19, 2015, 04:20:54 PM
I don't like either of them but I'd say that marketcap is pretty meaningless. I think volume is way more important but unfortunately coinmarketcap only tracks the last 24h. A long term volume graph comparison might be more interesting.
One is messured in 1m the other in 100k   ~3to1 the last big spike is less the 400k vs more than 1.2m


Thanks. It says a lot.
