Bitcoin Forum

Hello everyone! I hope this is OK to post in the newbie forum.

I have just heard about mining bitcoins and I would like to start doing it. Here is my situation:

I own a small business. Basically I run a computer lab, I have 32 high-end workstations in a room that anyone can rent out. Usually startup teams will come in and work in the lab. I have them all set up on a Gigabit network and they all have GPU's (nvidia unfortunately) with OpenCL and CUDA set up on them.

Lately I have been renting out only a few machines and the rest of them are sitting there idle. I'd like to use the idle GPU's to mine bitcoins! I pay a flat, yearly rate to the building owner for electricity so cost of power consumption is irrelevant to any profit I may make.

I am a systems administrator and programmer by trade so I feel it should be easy for me to get started. I've read the basic guides via google but I feel like I don't quite have a realistic grasp on how I should set this up. With my setup (32 GPU's), would it be feasible for me to mine bitcoins on my own? How do I distribute the work?

Any advice is appreciated.

better mine litecoins, it will takes months for your computers to mine a dollar worth of bitcoins.

Indeed that is what I was afraid of. What would be a realistic profit from litecoins?

hi
first, dl the Litecoin wallet
then sync it.
look at https://litecoin.info/Mining_hardware_comparison
for all your 32 PCs nvidia gpu
dl CudaMiner for mining on all the PCs
register on a Litecoin pool
set 32 workers
set 32 CudaMiner
set your Litecoin adress for payment
and go for it !

The 32 GPUs would be great if they were radeons.  Nvidia GPUs dont mine well at all.  Without changing the GPU's, you could do some CPU mining for some of the scrypt coins.  Check in the "Alternate Cryptocurrencies (https://bitcointalk.org/index.php?board=67.0)" section and the Bitcoin Wiki (https://en.bitcoin.it/wiki/List_of_alternative_cryptocurrencies).

Not sure which coins are designed for "CPU" mining only, but I remember seeing some info about that in the past.

Litecoin is a very good one to mine, but i would recommend this site to help you find out


http://www.coinwarz.com/cryptocurrency

Basically enter the amount of KHS  you get and see the results. The profits do change alot so be aware of that.

I would recommend this application to mine with:

http://guiminer.org/guiminer-scrypt.html

what cards are in these machines? and do they have 1 card each?

Do not mine bitcoins with those GPUs.

You'll do much better mining LTC with them.

Thanks for the advice so far! Is there a simple test I can run to figure out my KH/s on a single GPU?

Well, here is a good list of estimated KH/s for almost every GPU out there.

if you know the nvidia gpu go to
https://litecoin.info/Mining_hardware_comparison
you will see the Khash/s
X32 , it can be good for mining with CudaMiner
that's what i said in my previous post....

If you don't care about electricity cost then it won't hurt you to try and mine some altcoins. Download cudaminer to max your results for the nvidias.

Do not mine SHA-256 coins like Bitcoin with consumer hardware, it is not profitable anymore. Mine scrypt coins like Litecoin with GPU's and CPU-only coins like Primecoin with CPU's.

This, you can always trade easily the mined altcoins to Bitcoin
