    If that's the one I updated like three weeks ago, then yes. I just checked my users/appdata folder, it says FAHCore_11, so I suppose not. How do I update that again?

    I'm now getting 2962.29, but I upped the shaders to 1700. Temps are at 52.0C.

    I suppose I could try switching out the GPU spots, I just dread doing that o.o

    Edit: I just checked to see where the file locations are of the .exes core and the f@h exes. The folding@home.exe *32 points to the same location for both instances. Is this correct? My Fahcore_11.exe *32 points to each respective gpu folder (labeled gpu-1 gpu-2 respectively lol).

    OK, you have created 2 separate folders for the GPU2 client and unzipped GPU2 into both folders. I then always create a shortcut from each folder onto the desktop. I rename the shortcut based on the GPU that I want to run. You must then go into the shortcut properties and alter the executable to read************.exe" -gpu x(space before - and space after gpu). Is this similar to what you have done? Also, are both cards heating up the same(touch the back of core test)?

    Yup, exactly what I've done. And both cards get warm :)

    Last 5 units of mine were ok, running the 5506 project, but different run/clone/gen.

    Do you still get points for early finish units?

    Yes, a guess so, because it uploads the fraction done.

    Any changes in PPD? If not, you may have switch slots and delete all clients and shortcuts for a fresh install.


    On another note, the quad GPU rig is averaging 21K(@ 400 watts power consumption) and has boosted my overall ppd to 56k+. I see others are stepping up also. Thank You for your efforts. Below is the Top 20. We need some solid depth in the lower ranks. Anyone have additional GPU plans? Remember, I still have a few S-939 Sli boards w/CPU + Ram for free if you can fold with them. Keep up the great work guys!!!

    I miss my opteron processor...

    I'll try swapping the pci slots this weekend, and seeing if I can notice a difference. If not, I think I'm just going to get another 9600GSO and throw them in an SLi build in the future. If so, I still think I'm going to be doing that, because I don't want to lose the performance of my 8800GT in other things due to the pci express slot running at x8 instead of x16.

    NVIDIA GPU2 PPD Thread

    I was checking F@H forum - http://foldingforum.org/ - and found the nVidia Table Comparison:

    I guess could be very handy for those wondering to buy a new GPU! :):):):)

    Well ive never really tryed to OC my 3850 yet. so if anyone here could tell me if there is anything i can do to get a good OC out of it that would be helpfull. \

    EDIT. Now i have use the overdrive option in the CCC panel but thats it. If there is any more tweaking i can do to this HD 3850 agp give me a heads up.thanks

    Well, folding 3 days strait on my compy. No restarts. Gotta love Server 08!

    So far getting about 5300 OOD with the 8800 GTX. I used to get 5800, but I think I crashed the drivers to much with the Shaders clocked that high. I think for now I'm going to leave my Clocks at the factory "Superclock" levels.

    New 1.19 Core available

    From F@H blog:

    Culprit found in NV core v 1.15 issues for certain hardware?

    Engineers at NVIDIA (notably Scott LeGrand) have come up with a theory for the EUE's seen in core 1.15 (and a few others in the 1.15 to 1.18 range) on certain hardware. They found that this core had code optimizations that drove the GPU so hard that it would draw a lot more electricity (one sign of this was running hotter). In some boxes, this was too much electricity and this lead to numerical instabilities. When the same machine was given a beefier power supply, the problem went away.

    We've been told that 8800's require 600W power supplies, but we're finding that even a little bigger (eg at least 650W) is important to leave some room for error. We are working to see if there is some way to detect this issue in software, but for now, if you're getting EUE's on the NV GPU client, this is something to consider.

    By the way, this will be very important for us to consider future code optimizations. NV core v1.19 removed some optimizations to solve this problem, but there are many cards which would run fine w/this more optimized code. If we can find a way to detect whether the card can draw enough power, we may be able to choose different code paths to allow for greater optimization for cards which can handle it.

    We're still looking into this. For now, if you're seeing issues with your card, please consider trying out a bigger power supply. We will continue to look to see if this is indeed the problem and what we can do to help the situation such that the code runs stably on all machines.

    In short, the 1.19 core results in less PPD(2400 less on my 8800GS's). It has popped up sporadically and has 511 points per WU. Just keep an eye out for it.

    its getting that time to upgrade gpu's Giving the time of year I do not want to spend a lot, looking to try maybe a trade plus cash. I will just get a single card for now.

    So how is the gtx 260 or 280 for folding? any other suggestions on cards?

    Thanks

    I think i may be experiencing this problem, although i've never noticed it before. Every 1 in 6 units crawls along @ 2940 PPD.

    It's running project 5748 (R4, C511, G8)

    My GF and I came across similar WU's infrared. Both cards dropped to about 50% on unknown cores for those WU's. But now they're back on regular ones churning at almost full speed.

    I will have to update clients and see what happens. :toast:

    Well guys it looks as if I will be getting my new Hardware by the end of this month!:rockout: I will be buying the ASUS maximus formula II paired with a E8500 E0 ( i have the CPU on my desk) 2gigs of Corsair Dominator xms2 ddr2 1066 and a Sapphire HD 4870 1gb card .. this will be my primary pc for gaming and multimedia.. and yes more ppds!!:toast:

    The current rig i have now I will be selling everything i can in order to buy another 4870 1gb card.. But in the mean tim If any of you could maybe help me trying to get a better OC out of this 3850(agp) that would be great. Untill all the parts are sold I will continue to Fold on it while gaming and folding on the new rig during sleep and when im @ work(I work at least 35+ hours now) So if anyone has a 3850 agp card and knows how to push it a little further .. hook me up! Other than that FOLD OUT WITH YOUR COCK OUT:rockout:

    Welcome to the new nVidia "GPU Core 1.19"

    :nutkick: WHAT A NUT KICK!! :nutkick:

    Please, just read what I found out:

    [23:57:48] Preparing to commence simulation
    [23:57:48] - Looking at optimizations...
    [23:57:48] - Created dyn

    [23:57:52] CoreStatus = 6E (110)
    [23:57:52] + Core out of date. Auto updating...

    [23:57:53] + 10240 bytes downloaded
    [23:57:53] + 20480 bytes downloaded


    Yes my friends. Looks like we won't be able to keep our 1.15 core. The 1.19 is being updated automatically.

    With the 1.15 core, I had my WU done in aprox. 1:30 hour. With the 1.19 is taken 2:20 hours. :shadedshu - :cry:
