Picture of How to make money using your computer
Have you ever wondered if there was a way you could put your computer to work to make some extra cash?  Well guess what?  Now there is a website that has made this possible for everybody with a computer that has a newer video card!  In this guide we'll show a how to use the considerable computing power in your video card to make some extra money, even while you sleep.

There are just five simple steps to get started:

1.  Update your video drivers
2.  Register at http://www.compute4cash.com
3.  Download the Compute4Cash client
4.  Enter your account name in the configuration file
5.  Run the program in the background and watch the money accrue

Step 1: Update video drivers

Picture of Update video drivers
The Compute4Cash client requires some software components that only come with newer video driver packages so the first thing that we must do is update the video drivers.  You can download the latest drivers at the links below and follow their installation instructions:

For ATI/AMD video cards: http://support.amd.com/us/gpudownload/Pages/index.aspx
For nVidia video cards: http://www.nvidia.com/Download/index.aspx?lang=en-us

In order to use the Compute4Cash client you also need the latest VC++ package from Microsoft: http://www.microsoft.com/downloads/en/details.aspx?FamilyID=a7b7a05e-6de6-4d3a-a423-37bf0912db84

After installing these packages you will need to restart your computer to finalize the installation. 

Step 2: Download the Client

Visit http://www.compute4cash.com/index.php?downloads and download the Compute4Cash client.  It is a very small download so it shouldn't take long.  Once you have the zip file, extract it into any directory.  This is a good time to look over the README.txt, then move on to the next step.

Step 3: Configure the client

The Compute4Cash client has very little configuration and all that most people will need to do is change the account name.  The account name specified in the Compute4Cash.ini file is the account that will be credited with the work your video card completes so it is very important to make sure it is correct!

Open the Compute4Cash.ini file with notepad and on the line that says "ACCOUNT=" remove the default value and replace it with the account name you created on the Compute4Cash website.  Then save and close this file and move on to the next step.

@ these folks who are 'spreading awareness' about Compute4Cash -

Your information is not accurate regarding Compute4Cash and we would appreciate it if you would correct the misinformation you've been spreading.

Compute4Cash is not poclbm, it is an original C++ client based on the same OpenCL kernel, with a few minor modifications. Please stop inferring that it is a ripoff of someone else's code. The OpenCL kernel is public domain and the original author himself has stated in public that he has nothing against Compute4Cash.

Compute4Cash is not taking 50% either. With the current difficulty and market value, at $0.20/WU, Compute4Cash is only making about 20% and we have now implemented a variable rate that tracks the actual cost of a WU to help further reduce that figure. The variable rate is still under development, so it isn't perfect yet, but it will be soon enough. Compute4Cash's expenses are much higher than the nearly free-to-use pools so we require a higher percentage of the profits to stay afloat, and we offer a much nicer service than the other pools do so 20% is quite reasonable. As things stabilize and mature we will lower that percentage even further.

Now that you all have made the Bitcoin <-> Compute4Cash connection public we have publicly acknowledged and embraced this connection. We have added a few links to bitcoin.org on our site to help raise awareness around Bitcoin and we now offer to deliver payment in the form of Bitcoins for those who want them.

At this point the only difference between Compute4Cash and the other pools is really just the marketing/advertisement and we make the whole 'mining' experience easier for our users. Compute4Cash appeals more to people looking to make USD/EUR/LR/and so on rather than BTC, but BTC is available as well for those who want it.

Compute4Cash is still relatively young and it has been a bumpy ride for us so far as we mature and develop our service, and a lot has changed over the last couple of weeks. Before you post any more about Compute4Cash, please make sure you've got your facts straight. Thanks.

We're still trying to make people aware that compute4cash is essentially ripping off open source code and exploiting bitcoin to make money.

compute4cash is actually using your gpu power to make bitcoins (http://bitcoin.org), and then exchanging them for about twice as much cash as he pays you. Bitcoin is an online currency which you can exchange for cash, services, and other goods. The exchange rate is currently at about 1 USD per bitcoin. If you chose to do this on your own, rather than through the compute4cash middleman, you will make more than double the money.

compute4cash is being dishonest in telling you that this is used for computation or “data compression for the financial sector”

compute4cash is using an open-source miner called Poclbm (https://en.bitcoin.it/wiki/OpenCL_miner). At current difficulty and bitcoin price levels, the guy is making >50% profit on this. Any of you who are participating in the compute4cash pool, would do better on your own, using a free open source gpu miner. where better == about twice as much return.

I encourage you all to learn about bitcoin and cut out the middleman.

The following is a canned response generated by the people in #bitcoin-otc on freenode:

compute4cash is being ambiguous to the point of dishonesty, in telling you that this is used for "data compression for the financial sector".

You are factoring in the cost of the hardware as though people are expected to buy a computer to dedicate to Compute4Cash, but I don't think that is Compute4Cash's intention.

You certainly could go buy a load of 5970 cards to dedicate to this, and by my estimation it would take less than 6 months to break even (which is pretty darn good for a business which is what you'd be turning this into), and yield 100% return in a year, but I don't see anything on the www.compute4cash.com website that suggests people should buy hardware solely for Compute4Cash. It seems instead to be aimed at people who already have a newer video card to give them an opportunity to make a little "free money".

You are of course right about losing money in some cases, if someone has an older, inefficient video card, and/or their electricity costs or too high then they may not be able to net a profit at the standard rate of $0.10/WU. Everyone should be able to profit in every case with the promotional rate of $0.20/WU though, unless their electricity costs are absurd.

FYI, I only paid $520 for my Radeon 5970 around Christmas time :D They are going for $560 on Google shopping right now, but if someone really wanted to buy hardware to take advantage of this opportunity but didn't want to drop $560+, they could get a Radeon 5870 instead for $220 and probably get better than half the WU/hr rate of a 5970.

I do hope you have nothing on the computer that your worried about or is of a personal nature.

Who knows what this download is doing to your system or using your internet connection for??

Fancy a prosecution for spreading spam e-maile for example??

I think not - even if it is somehow legit.

Well it seems to do what it says - MSI Afterburner shows my GPU usage getting pegged when I run the program and it doesn't seem to use much network bandwidth. It is also a really small file so it doesn't seem like there is much room for anything other than what it claims to do. I haven't seen it attempt to connect to anything on the internet except www.compute4cash.com, so that's good.
It could, I am not saying it does, download spam ad retransmit using your connection to make the source. How would you know?
It does only transmit back to the host site. The SCAM however, is a bit more innocent i'm sure.

I'm guessing the creator is offloading the majority of the cost of running the computers and video cards to the user. Giving them back a small portion of what it's actually costing them, while they reduce costs by simply running run of the mill web servers instead of powerhouse number crunching machines.

I don't think it's fair to call that kind of business a scam, that sounds like regular 'ol business to me. In fact, that is how I would expect everything of this nature to operate.

I did a little math for my Radeon 5970:

5970 TDP = 300W, 1 kWh = $0.10
0.3kWh * $0.10 = $0.03/hr electricity cost

My 5970 nets ~2.08 WU/hr, 2.08*$0.20 = $0.416 revenue/hr

So my cost is three cents per hour and I make more than 41 cents per hour, net profit is 38 cents per hour, 24x7 = $64 per week, or $255 per month of profit. That doesn't seem to bad to me!

What else can I do with my computer to make this much money without needing any of my attention?
It's probably also important to note that the $0.20 is an introductory rate that ends this month... the shortest month of the year. Effectively cutting your profit margin in half as of March 1st.

And that $0.10 per kWh is not standard across the US. Many markets charge higher rates, upwards of $0.24 per kWh. The kWh rate also varies by time of day and of course by month. As you can imagine, during the month of July when everyone is running their AC units, the cost per kWh tends to spike pretty dramatically.

So let's run your calculations again with the average cost of electricity for say, the Chicago area. http://www.bls.gov/ro5/aepchi.htm

0.3kWh*$0.144 = $0.0432/hr cost

So let's take your next figure here.

5970 @ 2.08WU/hr *$0.10 = $0.208 - $0.0432/hr = $0.16/hr * 24 * 30 = $115.20/mo profit

Much much less. But still, essentially it's free money. Although keeping your video card under full load 24/7 also reduces the life of the card, and likely other components in your computer including but not limited to the power supply.

There's also the cost of the computer, and the Radeon 5970 which is up words of $700 for a single card. And you can't figure the cost of running just the card, but the whole computer has to be considered. Not to mention older less powerful, less efficient cards are more likely to be used. It's not really a "scam" but it certainly plays on people who don't think those kind of details through. Hence my comment on it being an "innocent scam."

And food for thought, the same calculations done with a Radeon 4850 have you actually losing 1/10th of a cent per hour.
Just a word to the wise about malware (i'm not saying this is maliciuous i'm just sending a warning): some of the simplest and most nasty viruses are written with only a few lines of code. with only a few extra KB a piece of software can change dramatically. Small file size is not a good measure of maliciousness.
