With a $10 000 rig:



Only

188MHASH@quark

But with 30 970 cards (will cost around $10 000)

you get

540 - 570MHASH@quark

Testing sp-mod release 72 opensource

On the GTX 970 OC windforce G1 boost: 1505Mhz core clock I get

19MHASH in the quark algo.

The titanx reference is doing 20.8MHASH

(source http://cryptomining-blog.com/tag/gtx-titan-x-hashrate/)


But the Titanx costs $1000 and the gtx970 1/3rd of that..


So I get 3 gtx970's for the price of one titanx. and almost 3x the hashrate and income of the $1000 spent...

You can boost the core clock as well if you put the gpu in the p1 state.

p2 state: adjust memory
p1 state: adjust gpu boost clock

I think I will make code that does this automaticly with an option.. --Max-Boost --Max-memspeed

1. List all possible modes, parse the information and select the fastest for each gpu in the rig
2. Set p1 mode and set the max possible gpu-boost clock
3. set p2 mode and set the max possible memclock clock

The NVIDIA api is broken in x86 builds, so I will call the commandline from the c++ code in the same way I have done before. (windows only)

For 970 cards with 4pin+3pin connector, boosting is important to reach full speed. (but this costs more power)

Other cards will probobly trottle and perform worse..

(f.ex all the gtx 970 mini cards, and the 970 cards that are made small to fit in a small box.)

I tried it some months ago on a 970 and it worked, but you loose the auto clock tuning based on temperature and fan speed, which you may or may not like ;-)
I personally like it and ended up with better hashrate using the default settings than changing it with nvidia-smi, but YMMV.

Hi all, could this thread be relevant for Maxwell based mining? Supposedly there is a trick to boost memclock safely using nvidia-smi.

And the altocoins are up, and the mining profit meassured in BTC is up..

and the price rebounded ;-)

According to  http://coinmarketcap.com. Bitcoins  has been traded for  $259,625,000 in the last 24Hours. But this webpage doesn't include the biggest chinese exchanges like OKCoin, huobi, BTCChina and Bter

The bitcoin USD market is just a small fraction of the world market. In the recent rally  more than 1 billion$ worth of bitcoins has been traded in a couple of days.

Another interesting point is that there is Arbitrage between the CNY exchanges and the USD
   
Huobi (china) $431.73/ (2740.21 CNY)
Bitstamp       $389.98

Bitcoins are 10% more expensive to buy in china than in Europe / America. Perhaps because somebody is buying in china and selling in europe..
Perhaps someone is moving fiat currency trough the bitcoin blockchain between borders without having any governement control...

that could be the case mate ...

which ever way - we are all be speculating anyhow ...

the beauty about it all is - that btc IS moving - and moving very well at the moment ...

if you injected another few million dollars ( like the winklevoss bros did a couple of years back with their $11million ) - then the movement would be very nice upwards again ...

ive never really been hung up about btc / fiat prices ... coins are coins are coins ... you can use them all if the service giver is willing to accept the coin you are willing to trade ... so its no major issue on this end ... i just like to watch - beats the hell out of sports ...

btc however IS a serious confronting notion to the big players in this world - the ones that do control markets ...

so if it ever came out that 'they' were involved in the fiat price fluctuations - i wouldnt bat an eyelid over it ...

give me my partner - good food - my place - my farm - and my sports car - and im a very happy guy which ever way it turns out ...

Perhaps allowing ethminer to run on the 750ti's?!

I'm not sure it is being pumped. Pumping altcoins is relatively easy but bitcoin takes a lot more capital. Not government
size, not megacorp size, but players currently bigger than anyone else currently in the crypto market to be able to
manipulate the price of a USD 6B security by 100%.

Like I said before I'm liking the idea that the Chinese are turning to bitcoin to circumvent currency controls.
If so it's a big step forward for crypto.

lol yaah I suppose he could... Terrible profit margin though

I'm not trying to pick a fight here but I think you're wrong. If I was to bid in an aution for a security that is
exchanged on an open market I would submit my bid at the last possible moment for fear that the price
could drop and I could be left holding the bag with a bid above market. It's all about minimizing the time
between selecting a bid price and getting delivery. The longer the time the more that could go wrong.

If you don't believe this is the case let me tell you about when I worked for a low tech telecommunications
company (post office). Government tenders closed at 5 PM so every time there was a tender closure everyone
was told to skim through the last minute incoming mail searching for tenders (the envelope were highly visible).
Unlike Bitcoins, the cost of the contracts didn't change from day to day but the tenders still flirted with the deadline
even with the unreliable post office. With this bitcoin auction all you need to do is send a PDF which can be done,
liretally, at the last minute.

as with any bidding system - the winners are ALWAYS the snipers ... those that come in at the last minute ( in this case - day or hour ) and bid a ridiculously left wing figure to win the auction ...

registration and the like is of no consequence - they would have already set that up a while back - and because its private - no one knows what the other is bidding - but they sure as hell know what the current prices are - and the upward trend that its currently taking ...

this does NOT mean this is the reason for the increase in btc fiat price - nor does it mean that the ptb ( powers that be - ie govt and organizations ) are whaling themselves into a btc frenzy ... what this DOES mean is that the btc market ( like any other ) IS manipulated by the ones that CAN AFFORD to do so ...

the argument is not whether the the auction is the casue of the price rise or not - it is about the reason WHY its being pumped ...

if you think 6billion dollars is a great deal of money - it is ... to us ...

bill gates could pull that out in a single credit card swipe - or signature ( im being over dramatic about the credit card swipe ... well - i think i am anyway ) ...

but take a look at the REAL rich - those of rothschild and rockerfellers and such ... those that can benefit from a business transaction ( like a war ) and make a profit of 200BILLION and above ... think people and corporations like that cant sway the market? ...

bitcoin is THE thing that has revolutionized the transactive industry ... as much as 'they' make out that is not worth a pinch of salt ... its 'them' that have the power to buy in MASSIVE quantities and sell the same ...

we little fish can ride the wave - but i can assure you that is these really BIG fish - the wahles - that are making the biggest splashes ... ie - manipulating the price as they see fit ...

laws are not made to be broken ... but there will ALWAYS be those that will bend them just before breaking point ...

and those people / corporates are the ones that have the power to do so - and are IN power to do so ...

which is fine - as long as we all conform ( hence some of teh stupid laws they are coming out with for the crypto communities ) ...

until there is major change in th way we all THINK - then will be no change in the way we work ... so this will keep happenning time and time again ...

in any case - i guess we all have our own direction ...

so the hardworker clued up is worried and stressed over the days that come - while the clueless are living an ignorant happy life without knowing any better ...

sometimes i wonder which ihas the better quality of life ... hehehe ...

anyway - back to work for me ... more stupid heat issues - causing more breakdowns ...

hope everyone is having a happy btc wave day ...

I sure do. As I said that was an example. Even if the BTC bid is at $300 per coin, right now still a $130 profit per coin so the example still works.

Also 90-95% of bids was probably already received when the price was still at $240-$250 range. I seriously doubt anyone who tried to bid within the last 24-36 hours probably did not meet the deadline with going through the process.

As I said though. I seriously doubt this auction is driving up the price.

EDIT: On the registration fee it is not like you lose the $150,000 or whatever it is. They send it back.

You do realize that highest bid wins so $175 just a waste of the bidding registration fee. All the serious bids
will be submitted at the last possible moment and will depend on the BTC price at that time. Nobody is going
to get them cheap.

I seriously doubt the auction is tied to the price rise. I agree with sp_ it is something else causing it.

But could it play a small part, sure and this is just my conspiracy theory portion.

Say you personally bid $175 per BTC so you bid $7,000,000 and think you are very likely to win (again this bid was placed days or even w week or so ago).

Now these last few days you have been buying BTC here and there up to $350-$375 mark and the rest will start buying also raising the price or keeping it there. You win the bid get the BTC and dump them at $300 each or hold some. Net profit $5,000,000 pretty quick. Now if you had the cash to pay $7,000,000 up front for cheap coins the you can afford to buy some up here and there to get the price where you want it.

Again I am not saying this is happening but I honestly believe the Govt is not pumping the price of BTC for a higher bid, unless they are secretly taking bids after the deadline.

I agree again with sp_ something outside the auction is driving the price and I don't think it is Russia as they are trying to pass laws to jail people for using BTC.

if the price rises while bidding is open it will just attract higher bids, though not as high as the current price
fearing a price drop. I'm puzzled how the price rise is tied to the auction. If a large amount of BTC are
expected to come onto the market it should push the price down, not up.

I also doubt there is any goverment involvement in the pump. With a market cap of of USD 6 billion it's not big
enough to attract the big players in the world. There may be some bigger players enterring the crypto world, but
not that big.

I like the idea that people are moving to crypto due to currency issues in their country. I have read that Bitcoin
is very popular in Argentina for that reason. If people in a large country like China were to take an interest in
crypto it could move the price significantly.

The bidding process was a sealed bid, meaning you have no idea how many people are bidding and at what price.

You send a bid of say 5 million dollars along with the required deposit in cash of $250,000 (or whatever it was for this bid). The cash bid is sent to the broker and held in escrow until the bid is over and if you win then you must pay the remaining balance upon a said date.

Now these bids have been in for a while now. Not in the last day or so because of all the paper work and background check of the bidder. They are making sure that you are not a felon and other crime orginizations. There is a process that you must pass.

Now could the person or company that thinks they have the winning bid buy up the price of BTC the last few days to dump. Sure.

Remember the last BTC dump of BTC at $300 dollars per coin? They were sold through Coinbase and it was an orchistrated sale then and the coins was brought in within 5 minutes. There was absolutely no reason at the time to sell at that price because BTC was well over $300 but Coinbase made a statement that the seller was looking to cash out of their holdings of BTC. Just happened to be a few days or weeks after the 50K U.S. Marshal sale back then.

Again I see no reason for the U.S. Marshal or Govt to pump BTC for this sale as they are getting the amount that they have from the sealed bids.

Here is the link again from the last auction that had 50,000 BTC with a required deposit of $250,000

http://www.usmarshals.gov/assets/2015/dpr-february-auction/ 

I agree with you though that people are either making money or losing now or in the future. After this sale though maybe we will see where the price is at for the future, but I personally think whoever wins this bid cashes out before the end of the year.

so you are saying that a bidder will bid at 10% of the current fiat value - to win the auction? ... how does that work antonio? ...

if there is a HUGE pump happening all around you - then current bids ( private or not ) would be akin to the fiat value they can accrue AFTER the purchase - not after the bid ...

so if the current fiat value is high - would that not be cause enough to bid higher and higher again - to try and WIN the bid for a fiat 'profit' when you dump the coins? ...

remember that the 'sniper' wins the auction ...

but who 'wins' in the end? ...

the fbi account and the government coffers and all those that participated in the pump - thats who! ... as they usually do in a pump like this ...

but ... who really knows? ...

'we' play with little fiat ... these guys play with VERY VERY VERY BIG fiat ...

i watch and do my own thing - in the background ...

and its a fun show to watch ... and learn ... ...
