I learned that from my buddy, who bought an ES card from CL that has that problem. He did some research and he said that's the reason. He said one could look at the board and tell if the card will have that problem -- I don't know exactly how though.

The only info I knew is, the card will work well except that though all(??, as there are typically 4 of them) NVIDIA HD devices show up in device manager they will all have a "!" mark. Also I am not sure if this really matters as the computer should almost always have other HD audio devices (typically true, since who will rely only on graphics card's audio devices??). Well, HDMI link now may not have audio signal -- again not 100% sure if this can not be worked around....

poor lappy... @__@ haha

This sounds more like a wrong file path/name problem... copy the rom file to where the nvflash.exe lives and run the cmd directly from that directory.

Is your card the original part in your system or you bought it somewhere else later on?

Prema, has your lappy recovered from the surgery?

Can anyone confirm if their ES version cards have audio issues? I heard that early versions of the ES card can't get HD audio devices to work and that is a HW/board issue, not a bios or driver issue...

Oh great, thanks!

I googled 'quadro inforom' and found an interesting pdf file.DA-00862-001_v20(1).pdf looks like inforom is something like a separate part of the rom image, and I had a remote impression that ECC is tied with that rom. Without a good inforom, nvsmi would not report ECC support. And looks like starting from k5000m inforom becomes part of the vbios rom. Not sure if a reflash of the vbios would remove inforom too. Anyway, I'd appreciate if a k5000m owner can try nvsmi and see if their k5000m cards have inforom info properly reported. Thanks!

By the way, based on my experience with multiple different quadro cards (desktop and laptop cards), I always see meaningful output when using 'nvsmi -q' for the following, or at least for the Image Version field. I never see a quadro card that seems to have no inforom information at all. Inforom Version Image Version : N/A OEM Object : N/A ECC Object : N/A Power Management Object : N/A

It's a DELL vbios ver: 80.04.33.00.35 I did a search yesterday and do see that k5000m supports ECC (see the link to the pdf file). http://www.nvidia.com/content/PDF/line_card/5409_NV_ProGraphicsSolutions_LineCard_FEB13_HR.pdf

I already tried nvsmi but got the following "ECC features not supported for GPU 0000:03:00.0.". Not sure why. It's just weird. The card is otherwise perfect.

I have a dell quadro k5000m but unlike other high end quadro cards I can't find an ECC state option in nvidia control panel. I suppose k5000m should support ECC? I searched online and read nvidia's official feature list, but couldn't find an answer. Some sites say it does though. Can any k5000m owner confirm if they can turn on/off ECC on their cards? Thanks!
