I'm new to Folding@Home, but am really interested in helping out. If I understand correctly, the folding procedure works by utilizing idle cycles of the CPU. So no matter what you do with your PC, folding won't interfere CPU usage. Correct?
Recently I got an idea with my friend and that is to build a powerful PC funded from part-time jobs and use that PC as a dedicated folding PC. What I want to know is that if it is possible to make the folding procedure utilize all available CPU / GPU horsepower
Happens all the time, I have 3 pcs that do just that. They are called farms. There's no need to specialize anything, the less you use the pc yourself, the more that goes into folding. But if you're in Word document, your CPU usage is just about zero anyways. Seriously.
This is the setup that you are dreaming about. It utilizes GTX295's, known for very high power consumption.http://foldingforum.org/viewtopic.php?f=38&t=8985
Maybe a threshold like 70% CPU and 80% GPU maximum usage.
Why? I admit if you're a gamer you may want to turn off gpu folding, though my roommate played games with it on and he never had a problem.
On the other hand I have tried the cpu limiting and it does work, but that process all uses cpu cycles, I found it to be inefficient.
CPU limiting is not useful, and GPUs have one 1 issue; In 2D windows usage they slowdown a tad, but never in 3D or games. The problem is slight but noticeable. I've never turn off folding because of it.
In an attempt to help all life I want to get on as fast as I can and building a dedicated folding PC sounds good. What do you think?
You're more than welcome. My pc #2 was made with leftover parts, but later as GPU folding caught on I found myself buying parts just to fold.
You have a number of things to consider.
Spare parts, what you have, then what to buy. Warning - it's addictive.
You pay for electricity? It will add to your power bill. How much? Well depends on what you build, and how many builds you have.
