    Hello Everyone,
    I'm trying to determine if I have an issue with my quadro 1000m graphics card on my W520. I believe I have a defective card, as I cannot run folding at home on the GPU but I can run it on the CPU at full throttle without any problems. I experience system lockups as soon as I begin to use the GPU as one of the slots on F@H. Do any I you guys have problems folding with the quadro on your W520s? I know the 1000m isn't as powerful as the 2000m, but it shouldn't be locking up.

    There are two GPU's in your W520. Have you tried to isolate if it's the Intel or NVIDIA gpu causing the problems with Folding@Home?

    It is using the Optimus card. I confirmed this by using a GPU monitoring tool with the quadro selected.

    Did you have any issues using the GPU while folding?

    It was my first time folding, I ran for about 4 hours. The cpu was at 100% and there were no issues using the Quadro 1000.

    Sounds like it could be gpu related.
    They do have a Folding Forum, maybe someone there can help.
    Hope you find the problem.

    I suggest to go into the BIOS and under the Display settings change the setting from Optimus to Discrete. Be sure and Disable the OS detection setting immediately below the graphics card setting.

    Test that and see how it works out.

    Yup. Tried fiddling with all different combinations of those settings but they all ended in the same result. I've ruled out a power supply issue, as I was curious if I had a defective power supply that could not handle a necessary amount of wattage. I ran the CPU flat out with no problems and then used the GPU exclusively for a trial run. They both consumed the same wattage according to Lenovo power manager but the GPU crashed and burned again. And it's not an issue with GPU core temps. GPU shark indicates the core is only reaching no higher than 70 degrees Celsius before crashing. I believe I have either a issue with the GPU or the video ram, as I've experienced lockups and bsod with anything even mildly taxing the graphics card on AC power. Even a script ran by Windows after driver updates on the quadro that was intended to rate the video card resulted in a bsod and crash.
