Graphics Card upgrade for M6800 ?

My understanding is that the Tesla M6 cannot output directly to any display, full stop. The outputs have been physically disabled on the card, flashing a different vBIOS will not help. You can use it in a laptop with Optimus only.

The other options are GeForce 980M and Quadro M5000M, as you mentioned. All three of them have similar performance. And they're only going to be around ≈20% faster than your 970M. To go higher, you'd have to look at the Quadro P3000/P4000/P5000 family... which require a vBIOS swap at the start for Windows to boot (you can flash them from Linux), and they are pretty pricey.

 

As far as I understand, the Quadro P3200/P4200/P5200 family video cards will not work on the M6800 with the LVDS interface, it's will only the thousandth series, without the two hundred prefix, can be launched successfully? There is simply an opportunity to buy Quadro P3200 and GTX 1060 on the local market, will they work ?! I attach a photo below..

Spoiler: available graphics cards in the local market

 

Any Pascal card without an ES vBIOS is unlikely to work in the M6800 with Windows. You will always get a BSOD at boot. You can boot Linux without issue. This thread describes the closest that I've ever seen someone get with booting a regular vBIOS Pascal card on the M6800 (GeForce 1070 in this case).

Thanks for the good advice!
After analyzing the market and the forum, I came to the conclusion that without global interventions in the design of the laptop, the following video cards are worthy of attention: GTX 1070, P4000 and P5000.
Of these, an adequate price for the first two video cards. According to P4000, I seemed to find somewhere a working BIOS for normal operation of the M6800 through the LVDS interface. As for the GTX 1070, it is not entirely clear in the subject: this video card was launched on the LVDS or eDP interface?!

 

I recommend that you carefully review the M6800/1070 thread (linked above) and also this post. GeForce 1070 is not recommended and would require some careful work and BIOS/memory hacking knowledge to get it booting Windows on the M6800.

It seems that the best solution, in my case with the M6800 on an LVDS, without crutches and sticks, and the best price-performance ratio, is the Quadro P4000..

 

Hello friends, my setup is dell precision M6700 laptop with nvidia K5000M. I decided to upgrade my gpu and I bought nvidia Gtx1070 gpu. Now I tested 1070 in linux/ubuntu. It is working well. but I have acpi bios error problem in win10. how can I fix this software error in win10?

 

You can't. Unfortunately, M6700/M6800 don't get well with Pascal cards. Your only options with Pascal will be Quadros (P3000/P4000/P5000) and you will need engineering sample vBios as Aaron said.

For using GTX 1070 you need a newer Precision, like 7710 or 7720.

 

Would it at all be possible to use a P5200? My M6800 is LVDS but I have no problem with using Optimus. Looking to run Windows 10.

 

No. No working vBIOS for this card has been found. (You could probably use it with Linux.)
