    Task manager works, but you must reconfigure at every re-boot. The software based versions have presets and you just click one button and done.

    I swapped out the 8800GS for an 8800T so now I have a pair of 8800GT's in my server. I finally got everything together last night after lapping my Q6600 and my Vendetta 2 heatsink. Nice and shiny but temps seem to be the same :wtf: Guess it was as good as it was going to get. Hitting about 62C on 2 of the cores and 57C on the other 2 while folding (3.6GHz @ 1.44V). I can live with that.

    Anyhoo... Here is ascreenshot of the numbers. Last night when I left it the 2 video cards were both working on 511 point units and getting about 3800ppd each. This morning one of them had a 384 point and the other just got a 511 point. These numbers look about right?

    I checked affinity and the 2 GPU FAHcore are set at core 2 and core 3 respectively. The SMP cores have 4 instances spread across all 4 cores. Anything I need to do to improve on the setup?

    Also, both 8800GT are clocked to 700 on teh core and 1750 shaders. If I back off on core can I push shaders higher and is that a better combo? For example is 650 core 1850 shaders better than 700 core 1750 shaders?

    Any tips or advice appreciated.

    Well, my second 9800GTX is now running. And I found that the reason the socket was faulty is because the home handyman, who used to own the place, grounded the socket through the built in vacuum cleaner also on the circuit. Solution? Change sockets! Subsequently also changed circuits. Still having an issue with the SMP client restarting from 0% upon closing the client, but I've been usually letting this sucker run. So without any further issues I shouldn't have to worry too much. Next comes overclocking, which will be my first adventure into that area.

    Why does my PPD go down when I have big WU? If it is to work 200 then it is 300, 1500-200PPD, and 2000- 111PPD.

    Bigger WUs take more power to process, so the CPU can do less PPD with a bigger WU. Usually the extra time is made up for the fact that you get more points for a large WU.
    My laptop just finished folding a 401 WU! Avareged 55 PPD, running at night. Somehow peaked at 346 PPD for an hour or so, don't know wtf happened there...

    Card Added

    Today I bought a new 8800GTS G92 to match the other I have.

    [​IMG]

    They were put together on a P5K, E6850 @ 3.2Ghz. Now I'm happy 'cos the SMP is folding well. Incredible 2 nVidia GPU Clients folding hard and the CPU usage only 2%~3%!!

    Before, this mobo was folding 2 ATI GPU Clients, that are too CPU demanding 50%~70% - not a chance for SMP.

    [​IMG]

    Tomorrow I will mess around my dual 9800GT rig. Adding a X6800 and setting up a nice SMP. :pimp:

    I was wondering for a while to do this modifications... finally the laziness drop-off my back and I'm doing it :toast: :toast:

    Finally got everything working right I think. I should start averaging 3000ppd now. Thanks for the help everyone!

    Oh, nice card mmaakk.:rockout: Those cards are becoming one of the better deals in folding cards. It's a shame they are hard to find/discontinued. Are you running Vista on the 88800GTS rig? Also, what Nvidia driver version are you running?


    It happens from time to time when the Assignment Server is experiencing high loads. Have you been able to get work since yesteday?

    Just out of curiousity what are people running the shaders at on their 8800GT for folding? My server is not used for gaming at all... only folding. I have a pair of 8800GT's in there and currently have core 700 and shaders 1750 on both of them. I am thinking they can probably do more on the shaders (like, say 1850 or so). If I reduce the core does that give me more headroom on shaders and is a lower core/higher shader a more effective folding solution?

    The 8800GTS rig has vista - 181.22 driver, but my 9800GT rig runs XP and the CPU usage is the same.

    I had posted about this matter when the 180 driver came out: nVidia solved the CPU usage with the 180.XX drivers.

    Not long ago I guess you posted something about that you're still using 176.XX driver. My favorite so far for win XP is the "180.84_geforce_winxp_32bit_english_beta.exe".

    This means that the servers are too busy or in maintenance. Don't worry it will solve by itself. Happens sometimes with me and really piss me off. :toast:

    Yep, I'm still using 177.83 on several rigs. I won't upgrade until I see a PPD increase. It take to long to load drivers for 4 gpu's per rig...:laugh:

    What version of SMP are you running? 6.20 or 6.23?

    Folding SMP mixed with GPU Client

    infrared gave this tip and works 100%:

    Fold with GPU Client in "low" priority and SMP in "idle". This way you can use all the cores for SMP without affecting the GPU folding performance.

    I have been doing for over a month with my gaming rig - GTX 260 and E8400. Works GREAT :rockout:

    I have my cards running at 702/1782/995 and 702/1836/995 actual speeds. Setting your shaders to 1750 will actually have them at 1728. They increase in steps of 54 MHz (I think someone actually posted the chart of actual settable speeds earlier, if you use rivatuner you'll see what I mean). Both of these 8800GT's have the 1.1V bios mod and some pretty damn good cooling, a bit ghetto but good. I also found that lowering the core clock didn't give me too much more headroom for the shaders. I lowered mine for less heat output since my PNY with the shaders @ 1782 will freeze if the temps get too high. Each card really is a little different, the best way to find out how to get your highest shader clock is to take an hour or two away from folding and experiment with different clocks and scan for artifacts with ATItool.

    Not SMP, just 6.23 console.

    Overlooked no longer. I just went back and viewed it & also left my thanks.:toast:


    I think I will try this today. Do I have to use the newer XP drivers for less CPU usage? I'll let you know how it goes. This is new territory for me, as I always keep my CPU and GPU clients on separate cores. Scary stuff:eek:

    Yes, using the newer drives you gain more CPU usage for SMP = +PPD :cool:

    Well, only a couple hundred before I mentioned anything :rolleyes: oops I really like running the SMP client in addition to the GPU's since I've heard they are more robust in the amount of positive work they do for the folding cause (something about the type of simulations they can run compared to the GPU, can't remember where I read that... will look for it after I walk the dog before it starts to rain/ice/snow here in about 30 min.) Only downside is the added power consumption.
