Graphics CardsProcessors. Bitcoin subscribe unsubscribereaders 19, users here now Bitcoin is the currency of the Internet: It's prolly the guiminer interface or something. Windows will require a dummy plug on any secondary video cards because the OS won't see it unless it has a monitor plugged in. How do you perceive that something exist when one person tells you that it exist, and masses of people join that ONE person to confirm that it exists.
I mean I know that it will probably run on the machine, that's not my concern; my concern is, will it run fast so using all hardware on the machine, all CPU cores and all GPU 'cores'. It's prolly the guiminer interface or something. It seems a bit low given: July 12, I'm not sure why, but your card is showing a much slower speed on one of the cores. If that is not the case, your friend can, as a last resort, install the x86 software implementation freely available from AMD search for stream SDK. Difficulty is about times larger now than half a year ago, btw.
Stack Exchange in Review. The AMD design is better suited to this type of computation. I think you can fit 3 video cards onto some motherboards, but again, scaling it up can be a bitch. Stack Overflow works best with JavaScript enabled. So, in many cases, you can fit two s onto a standard motherboard.

Eric 5, 19 OpenGL only works on the video card. Is this how it is supposed to work in the future? OpenGL always supports a software path for when the hardware doesn't support certain operations.
Something similar will probably happen with OpenCL. I don't know enough about Apple's OpenCL implementation to know what it supports. I mean I know that it will probably run on the machine, that's not my concern; my concern is, will it run fast so using all hardware on the machine, all CPU cores and all GPU 'cores'. The short answer is it's too early to tell, especially in cross-vendor scenarios. Also, there can be orders of magnitude difference between between using all hardware and using all hardware optimally.
Catering to the memory architecture and optimal work group size and on the different platforms will be of critical importance to get the maximum performance out of your application. Also, I think you're prematurely optimizing now. OpenCL is "the way of the future" if you want cross-platform, high-performance computing. Focus on learning the details now and optimizing for your current platform. Thanks for that, I was writing a new question to know if things had changed since the first answer Thanks for any input!
Hi Adster, I am running a XFX 2GB card with an edited BIOS to have unlocked shaders but not speeds though the card is capable of running at them, I didn't want to risk running the memory at the higher speed full time.
The flags that I mentioned will work for you , they are specific to the version of card you have, in this case these flags are best used with AMD 6xxx series cards. You can set the flags in the GUIMiner extra flags area; however, you will need to edit the poclbm kernel file for the other optimizations. You can find those by searching the bitcoin forums for kernel optimizations. I hope it helps, let me know if you need any help in sqeezing all the mhash possible outta that card: I am running an Asus with the shaders unlock but not the bios.
I am running phoenix miner 1. Honestly, we just didn't test it because we skipped some cards. Looking back, we should have done one of them. Try here for a lits of cards and their Bitcoin potential: This is a great article, and pushed me over the edge to start mining.
Obviously we are all subject to different utility rates, so you couldn't give a cost-breakdown that would apply to everyone. However, I am curious how much the average cost of electricity would deduct from the profits in your chart?
Does the amount of system memory matter when mining bitcoins, or is the graphics card the only real limiting factor? Linux or Windows doesn't matter. Windows will require a dummy plug on any secondary video cards because the OS won't see it unless it has a monitor plugged in. I did an analysis of the energy costs, which really should be factored in: The AMD design is better suited to this type of computation.
The second reason is that There is a cpu instruction that is heavily used when mining, and the AMD architecture implements this instruction in a more efficient way. The is also a pretty glaring lack, because it is the one that would compete the most with the It is definitely not as good, but it is definitely far easier to obtain a then a I get MHash from my 2xs -- Pretty far below 80ish? This is also not justly correct that only a few people get access to it and most people of the world is not having a chance.
There is roughly about 8 megawatts being consumed. A diesel train engine generates 4 so the entire network consumes about the same as a train being pulled by two engines. I think it is your responsibility to deter readers more actively from investing in hardware in order to conduct bitcoin mining and distance yourselves from those activities.
It is easy for people to understand that they can make money from computing power, but it takes some very careful reading to understand that by design, this whole enterprise will become less and less profitable over time.
So I think it would be better to put the emphasis of the article on parallel computing performance and to use bitcoin merely for illustrative purposes. At the very least, you should factor in the energy costs in your profitability analysis, but in my opinion, calculating projections is misleading and even deceptive, given the facts about Bitcoin see below.
So my warning here: The calculations of "Days to payoff" and "1 year profit" in this article are misleading: Not only is the rate of bitcoin creation is deliberately being slowed as the total number of bitcoins approaches 21 millions, it is also getting more and more difficult to accumulate enough computing power as the number of participants in bitcoin mining is increasing as people reading this article and others will start setting up their own mining operation.
The only effect countering this deterioration in profitability would be an increase in the dollar value of the bitcoin, which is uncertain and unpredictable. Read over the first two pages of the article again to understand WHY this happens but just know the results you will see below are based on an instance in time during this writing process!
Plus a virus which specifically only attempted GPU mining would be alot easier to hide in the windows environment since most users are unlikely to be monitoring GPU usage levels when simply web browsing etc.
A virus which intelligently slowed its mining attack if the user was trying to do something GPU intensive gaming , in order to hide the system use and keep the user from noticing massive in-game slowdown, could likely mine away unnoticed.
I do not fully understand the setup in regards to mining as a pool though, which is what you would ultimately want all your zombied systems to do. I guess it is probably not 'that' difficult to setup a pooling setup given how many continue popping up, plus presumably someone writing a virus specifically targetted at hijacking GPU cycles is probably a decent enough coder.
What price did you use for power in your profit calculations? Your profit after one year will be negative if your price for power is more than about 35 cents, assuming constant difficulty. All Nvidia cards will operate at a loss unless your power is very cheap or free. Difficulty is about times larger now than half a year ago, btw. Power cost has become the most important factor in mining profitabilty. For european readers, the power use is a bit more important.
Which means a system like the beast using 1kw of power will cost you 0. I'd be interested in a little more information. Do you know if the optimizations you mentioned the flags should work for my ; you said they are gfx card version specific - did you mean vendor specific, or just specific?
