I've been on the search for the cheapest yet best [email protected] machine for my home.
One particular reason why I am so interested is because I've been affected by losing my mother to cancer, its probably the nastiest diseases I know of, it honestly takes to many lives, this is why i'm so interested in building a rig just for [email protected]
Now down to business, My research lead me to various sites and resources and found some very useful articles, one thing is certain Nvidia is by far the top performers of all graphic cards.
There seems to be older articles about farming and building the best folding rig but nothing to recent, they all date back to 2009 and I found one from 2010. So this leads me to building a rig gives me the most points for money, I understand watts can be a factor but for me its the points in the end so I've put together a rig that puts out the most points per day with staying under budget.
Before I get into things lets make this clear, there are many options to building a [email protected] rig but this particular build I will state what hardware I would choose over some of the higher priced hardware.
One piece of information I couldn't let go and that was... building a multiple GPU folding rig is very different from building a gaming rig with multiple graphics cards, youâ€™ll need a motherboard with multiple PCI-E slots, as each GPU runs an individual folding client, it isnâ€™t necessary to buy a CrossFire or SLI-certified motherboard. Reason for this is because SLI and CF cannot be used to make a dual GPU card or cards perform like one super GPU. The SLI and CF link does not have enough bandwidth to support that functionality. Run one [email protected] GPU client for each GPU your graphics card has.
In addition, because folding isn't as bandwidth intensive as gaming you can also run folding on a graphics card installed in PCI-E slot with eight PCI-E lanes or fewer without a loss in performance, this means you can run graphics card on every PCI-E slot available.
CPU performance isn't necessary for a GPU folding client, however, if you're planning on installing more than three to four graphics cards (or cards with multiple-GPUs) you'll need a more powerful CPU. Keep in mind that each CPU core can run 2 GPU cores, so an eight GPU system will require a quad-core CPU to run optimally. Make sense?
First off, you need to make sure the PSU has sufficient PCI-E power plugs of the right type (6- or 8-pin) for your graphics cards. In my case I'm using graphic cards that done use PCI-E plugs.
You will also need to invest in some RAM and a hard disk for your folding rig and an optical drive to install Windows, but as none of these components has a direct effect on folding, you may as well buy the cheapest one you can find, or recycle components from an old PC.
Here is where its gets tricky, picking the right card (cards) for your particular build may differ from me but in my case I'm going for the cheapest yet highest point given card to date.
There are many graphs online which explain what card performs better ppd vs by the total power consumption.
This is just a personal choice I made for "as is" This isn't meant for upgrading for newer versions of GC but rather keep this tucked away and just keep as [email protected] rig.
My Hardware Choices and why.
I chose this motherboard because its AMD and had the 790FX chipset which I know can handle multiple GCs with out causing errors.
The CPU, this was a no brainer. I chose AMD Athlon II X2 250 for obvious reasons CHEAP and its all this rig needs.
These Graphics Cards seemed to perform the best for the money, the Nvidia GeForce 9600 GSOs average 4100 ppd EACH so a combined total of 16400 ppd. Not bad for the price, I'm not 100% certain that this is the best choice because of the older articles I had read.
If anyone has something to add please do, I'm planning on building this at some point this year, its going to be one of goals so please any input and advice or corrections would be GLADLY appreciated.
