    Hints & Tips on How To Get Extra PPD

    Here are some ways that you can get extra PPD (Points Per Day).


    1) Running websites, Java Scripts, and generally using your computer can atract spyware and adware to your computer. And of-course, they take up CPU cycles, memory, and other resources. You can remove these using Ad-aware or SpyBot Search & Destroy.

    2) Turn off all screensavers, background processes, etc. because they use CPU Cycles and other resources as-well.

    3) Keep your computer cool. When your computer runs hot, it slows down! So keeping your CPU under 65°C can help you.

    4) Settings to use when setting-up your F@H Client:

    • Disable Highly Optimized Assembly Code - No
    • Packet Recipt Size: Small, Normal, Big? - Big
    • Core Priority - Idle
    • CPU Usage Requested - 100

    5 Instead of using onboard video, get at-least a cheap video card to go in your PCI, AGP, PCI-E, etc. slot. - Onboard video output uses your system memory, can take up CPU Cycles, and slows down your computer. I was running onboard on one of my P4s and I put a AOpen Riva TNT2 32MB AGP that I got on eBay for $8 and I got a few extra PPD because of it. Also, I was getting 500 Point WUs (Work Units) on my Athlon 64 with 1GB RAM all of the time! but on my P4 with 512MB RAM I was getting 225 Point WUs, after I put in the Riva TNT2 I got a 775 pointer! and now I am getting better WUs.

    6 And the last thing is getting you to run your machine(s)! Running them 24/7 will get you the most points.

    I would like to see the difference in computing power between a CPU at 50 degrees and a CPU at 65 degrees :hatty:

    I would like to see that too, I might try that at the weekend.

    And also how it would affect PPD on different clients, also its quite a silly statement since each cpu different, I used to be able to run my prescot p4 at 75c before it would complain.

    It will be hard to keep as a fair test though.

    Also there are a hell of a lot more tweaks, most are posted in the sticky above, I shall add to it the results.

    I'm not sure if you're serious or not, but there will be no measurable difference what so ever. Theoretically it's possible as the colder it is, the less resistance provided by each transistor, which again leads to better efficiency (see how super conductors work). But in no way would this be measurable in a folding client, and not with temperature differences of 10-20 degrees!

    I was just being sarcastic. Sorry, I can be an evil pr*ck sometimes. :(

    Hmm, I'm not sure it is theoretically possible - I think (at least at today's speeds) the clock signal is sufficiently slow to accomodate the extra pS delay or so in transistors switching??

    Damn - I wish I could remember something about VSLI :)

    However I think that crossfire was referring to the slowdown that occurs in P4 and later generation chips when it exceeds it's operational temperature limit :)

    BTW Kudos to CrossFire for the idea of this thread and his efforts in holding this community together :)

    Sure, but the temperature limit for throttling doesn't kick in at 55c, and modern chips can operate at higher temperatures just fine. I would perhaps set the limit at around 65c or so. Hell, a stock Q6600 with the stock cooler will produce temperatures well over 60 degrees.

    Either way I was just being sarcastic about lower temps = better performance, I wasn't having a go at anyone.

    Yes John, apparently jokes and sarcasm don't work too well in forum posts ;)

    /me puts away gigantic leg pulling tongs :)

    4) Settings to use when setting-up your F@H Client:

    Disable Highly Optimized Assembly Code - No

    Packet Recipt Size: Small, Normal, Big? - Big

    Core Priority - Idle

    CPU Usage Requested - 100......

    How do you do all that then. where do u go to change it all ?

    When you are setting up your Folding@Home Client select yes when it asks "Change advanced options?"

    600mhz more clock speed gave me a 40ppd increase on the 2427 (on a p4).

    I don't mean to break in here, since I fold for another team. But if you want the points, I fold with a P4 630, P4 631, PD 920 and C2D 6320.
    They all fold SMP(windows) and are good
    for over 4000+ PPD
    The 630 is stock - 625 PD
    631 @ 3400 - 723 PPD
    920 @ 3200 - 1000 PPD
    6320 @ 2800 - 1900 PPD

    So if you want points fold SMP.

    Umm, sorry mate, but you can't run an SMP Client on a Single-Core Processor.

    You can actually ;)

    And if clocked high enough a pentium 4 will infact complete it by the deadline.

    What the hell? I thought we had this discussion already and came to the conclusion that you could not. :confused:

    I have been folding for four years. And doing SMPs on P4s since they came out.

    I also use XP on all machines, and run it
    as a service.

    Thats part of the fun. Doing it how it can't be done.

    But like I said, my 630 will make the DL
    without an OC - STOCK.

    If you run linux (I have used Ubuntu), then you get about a 10% gain in PPD.

    If you have any ?s, I'll check back and
    help you out.

    Happy New Year

    Keep up the fold!

    Yes, I've been trying to get a ethernet cable to run on my LAN port so I can run Linux on some of my machines. I can't use my Wireless Adapter. :(

    How can you change Packet Reciept Size in the GUI client?
