Quadro 6000 Not Recognized in new Build

[CalebPetersen]

Hi all, I just put together a new computer with components listed below. A Quadro 6000 I bought off of eBay is apparently getting power as green LEDs near the 6-pin and 8-pin power connectors turn green when the computer is powered on (if either of these is unplugged, by the way, the adjacent LED will turn red). However, it's not recognized at all: if I power up the machine just with the Quadro, I'll never see anything on the monitor, and if I use an older PCI-express video card and go into BIOS, BIOS doesn't think that anything is plugged into the PCI slot occupied by the Quadro. I believe it's seated properly in the PCI slot, and I've tried both of my PCI-e 3.0 x16 slots. I haven't done any overclocking.

Specs:
-Xeon E5-1620 v3
-1x16GB DDR4 at 2133MHz
-NVidia (HP-branded according to seller, although I didn't see any HP logo) Quadro 6000 (not K6000)
-Some old random PCI-express video card
-ASRock X99 Extreme3 motherboard
-500W Antec PSU

I can boot of a USB stick, so all other components should be fine. I've looked for manuals of any sort for the Quadro 6000, and this was the best I found (a generic Quadro manual): http://www3.pny.com/File%20Library/Support/PNY%20Products/User%20Guides%20and%20Tutorials/NVS/NVIDIA-Quadro---NVS-Userguide.pdf

Thanks,
Caleb

Not sure if this is relevant but have you checked the Boot button (tab?) in the UEFI bios and looked for Launch Video OpROM Policy?
"Launch Video OpROM Policy
Select UEFI only to run those that support UEFI option ROM only.
Select Legacy only to run those that support legacy option ROM only."

Hey Ken, since the old graphics card that works with the computer is ancient (2007 model), it might indeed be forcing legacy OpROM, which might or might not conflict with the Quadro 6000 since it's somewhat newer (in fact, the HP model of the Q6000 has "UEFI" in the very name, so it probably is a non-legacy OpROM). In BIOS, Video OpROM was initially set to Legacy only; I changed it to UEFI only, disabled CSM, saved and restarted, and hit delete to go back to BIOS -- not only was my card not recognized in the "device manager", but the Video OpROM policy had been changed back to Legacy! I also tried changing it to UEFI, saved, then shut down right as it was restarting and removed the old board before powering on (in case the old board was forcing it to use the old OpROM). Nothing ever came on the screen when I attached my monitor to the Quadro 6000.

Thanks,
Caleb

Technically, my power supply isn't PCIe 2.0 certified (and I had to use molex->6-pin adapters because my PSU doesn't have a single 6-pin)... Is that a problem? The graphics card isn't running at load and the power LEDs light green so I would expect it would at least get recognized.

Also installed card in an old computer (pre-UEFI BIOS) along with the known-working old card and booted into Windows XP -- Device Manager shows only the old graphics card, no Quadro 6000 or even an "unknown device".

I'm not sure what to tell you. I hope someone with experience with this card will be able to help you sort it out.
