Pascal GPUs with Dell Precision M6600

Try driver 389.XX it’s from Dell 7710 I think on Dell website. Modify INF and it should work 

The driver version i used from gigabyte on p106m was also a similar version but is 384.74, that partially worked on that benchmark. seems like something on the new drivers broke functionality with this type of optimus on m6600 or other sandybridge systems for the pascal gpus. 🤔

On AW 419.67 is the last driver that lets me use RTX 3000 and Intel hd 3000. But DX12 doesn’t work only DX11.

 

on M6600 389.xx driver works but same issue , no dx12 support

I am so confused. My service tag is 14DVLQ1 and I have a Quadro P4000. The best I can tell I have a LVDS display and I can only get the system to display anything on the first boot (ie clear CMOS every time) but displaying only goes as far as bios and not os. However I can ssh to the system but it doesn't show the card.

Every subsequent boot doesn't even show the dell splashscreen.

 

In bios with the new card it shows as "unknown panel". From what I understand P4000 doesn't support LVDS so I am exceedingly dumbfounded on how this is suppose to work (is it?) Intel GPU displays from Nvidia GPU?

 

Given I can't seem to get it to work any input is appreciated, this is very interesting mix and match for a laptop.

 

(Bios is rev A18 and I am fairly confident the GPU is not dead but who knows)

have you flashed your quadro p4000 with engineering sample for m6700/m6800?

I have not I suppose I shall research this. Thanks.

Thanks for that info! Somehow I missed it, I've read your other posts and I've gotten the applicable vbois and I'll be ordering a adapter to flash it. Might be a few weeks but it will be fun!

Well I got my cheap mxm -> pcie adapter (Chinese mining thing "GPU Host v2.1"). I fiddled with it but no dice. Short and sweet is that is a whole can of not-worth-it-worms.

 

On a whim I reinstalled the p4000 into my M6600 and for some reason, it posted and booted like nothing was wrong. Really bizarrely I cannot seem to replicate it as of yet (HDMI was in). I do not need to replicate it for now I just have to get the card flashed. I have verified the p4000 works (at least once). Oh and BTW dear reader, it did not shut off after the post it just went straight to grub (Linux) on that one off. I shall fiddle with it some more and see if I can get it to work all of the time.

More updates, the P4000 I have is a DOA card. That one in a million behavior is just the integrated graphics kicking in.

 

Upon closer inspection this had has some minor damage around some smd components. Back to square 1.
