    Default Important: clients for single-core, multi-core or GPU systems

    This mini guide is to help those new to folding choose the correct client and be aware of the options available. This guide does not currently contain any information about the client option available for Linux, but there is a multithread client available for both 32 and 64 bit variaties along with the standard single threaded versions.

    You should be aware that the graphical client is single threaded, it will not make the most of a dual-core system. If this is how you are currently folding but you have a dual core system, scroll down to dual core CPU's and consider this method for a 100% speed increase.

    If you have an X1900XT or above, don't bother with the CPU clients, choose the GPU client instead even if you have a quad-core CPU as it is upto 40 times faster than the CPU based clients.

    --- Windows CPU clients ---

    Single-Core CPU's (P4's, A64 etc)
    If you have a single core CPU (P4, Athlon 64 or lower) you should choose the basic graphical client. You can find it highlighted in a light grey on the download page at the folding website.

    If your new to folding, i would suggest you use the graphical client as it's much easier to use and get familar with, but if you have a dual-core CPU and are feeling 'ard, you should definitely read below and do this instead.

    Dual-Core CPU's (Pent D, Core 2 Duo, Athlon X2 etc)
    Currently there is no multithreded client for Windows BUT there is a way to get both cores running at full capacity, so those of you with dual-core systems will get double the performance by using this method.

    The graphical client cannot take advantage of dual-core systems, it will only use one core giving you 50% CPU utilisation, however, if you run the text only client you can get 100% utilisation and double your speed. To take advantage of this do the following:
    1. Uninstall the graphical client and download the "No nonsense" text-only console client.
    2. Create two folders called 'Folding 1' and 'Folding 2', place the FAH504-Console.exe into both folders.
    3. Click on the exe in 'folding 1' and you'll be asked some questions, answer as follows unless you know better or have folded before:
    • User Name: enter your forum name
    • Team Number: enter our team id (52950)
    • launch as a service? N
    • ask before fetching work? N
    • Use internet exlorer settings? N
    • Use Proxy: N
    • Allow receipt of work..? Y = 1GB+, N = less than 1GB.
    • change advanced options? Y
    • core priority? Idle
    • CPU usage requested? 100
    • disable assembly code? N
    • Pasue if battery..? N (unless using laptop)
    • Interval between checkpoints? 5
    • Memory to idicate? largest amount you can or just press enter without answering
    • Request work units without deadlines? N
    • Set -advmethods flag always? N
    • Ignore any deadline onformtion? N
    • Machine ID? 1
    As already said, you don't have to follow these settings if you know better. After you've done this the client should download the work and start folding. If so go into folder 'Folding 2' and repeat all the above steps only this time when asked for the Machine ID choose 2.

    Once both clients are running you will get 100% CPU utilisation and will double your work output when folding

    What about Quad-Core?
    If you have a quad-core machine or higher you can simply create more copies (folder 3, folder 4, etc) with the same settings but with a unique Machine ID all the way upto eight cores. tip - simply name the machine id after the folder number to keep track of which Machine ID's you've already used.

    --- Windows CPU+GPU clients ---

    Work in progress, this quote from anandtech may at least help explain this a little until i complete this section.

    Modern GPUs such as the R580 core powering ATI's X19xx series have upwards of 48 pixel shading units, designed to do exactly what the Folding@Home team requires. With help from ATI, the Folding@Home team has created a version of their client that can utilize ATI's X19xx GPUs with very impressive results. The Folding@Home team is saying that the GPU-accelerated client is 20 to 40 times faster than their clients just using the CPU. Once we have the client in our hands, we'll put this to the test, but even a fraction of this number would represent a massive speedup.
    ----GPU folding update----:

    For some time now (around a couple of years) there has been the GPU 1 Win v6.0 (text or GUI) client supporting ATI HD X1xxx cards but support for this is coming to an end.

    In its place is the GPU 2 Win client supporting ATI HD 2xxx/3xxx and beyond. this is currently in open Beta testing so occasionly runs into trouble as the version increments but is generally shown to be solid.

    Upcoming is the GPU 2 Win client supporting Nvidia GPUs. This is currently in closed Beta testing with the expected open Beta due probably July '08

    EDIT: 18th June 2008

    The Nvidia BETA Client is now available (Details to follow)

    So I join and set this up. Does it work like a screensaver... ie. cut in and start running automatically during periods that system is idle? Then what happens when I need the processing power for tasks? must I switch it off or do I get priority?

    edit : more .....What should I read for info re folding on a work computer not connected to internet?

    I've set it up for four cores now and at first I too started to get these errors but my just levelled out and started to work.

    Folding folder 1 is working on 1 wu and 2 3 4 are working on a differnt one ? :S

    Stanford have released the new GPU2 client for NVIDIA cuda graphics cards...that is 8xxx and 9xxx and a couple of others

    I hope to try this this weekend

    Be ADVISED these are first release BETA clients that need specific drivers to be present and while they may work on VISTA they have XP optimisations just now
