If you need any tips, just PM me Edited Octoby szumial I wish it was more stable, but still it runs great. If anyone reads the thread - I was succesful with the upgrade - everything installed and working. Other useful info: I have a spare Quadro K5100 to try out, but from what I've read, there might be issues with that one as well. That's when I come to you asking for help - I've seen people upgrading their laptops with the impossible, so I believe there's still hope. Question is - how deep do you have to get into modding to make it work? Is the GTX 880m even worth the effort? Maybe I should search for a way to mess with M6700 BIOS? You might wonder why I want it - the answer is simple - I don't want a Quadro card here as I see a potential for some gaming on the workstation which has excellent build quality and great computing power. I still believe that it is possible to make it work if it's only a software issue. Installing drivers (DSE turned off obviously) sometimes gives a post "no compatible hardware was found" and at other times with different mods and versions I get a message that it was all recognized, yet the driver "migh have been corrupted or smth".

I tried flashing different vbios, updated the Dell bios to the latest one (A15), and tried modding NV drivers - no luck so far.

Apparently my M6700 wants to perform only on Intel HD graphics from the CPU (3940XM). I managed to install all the nVidia components, yet can't get the card working properly - launched Bioshock Infinite to see if it is on and it wasn't. So I browsed through lots of topics on upgrading, modding and customizing drivers but none of the methods worked for me, apart from one - Mr Fox's modded desktop drivers. Windows 10 圆4 Anniversary Edition works and recognizes the GPU as "Microsoft Universal Video Adapter", but the HWid suggests it's a GTX880 - in fact I can even see it properly detected by GPU-Z. When I plugged the card in I though it was all I needed to do - I'm used to desktop upgrades, so I thought - it fits - why not? Turns out the PC's BIOS can't figure out what card is in it - with Optimus "off" I can see "unknown video card" with 8GBs of RAM.

The laptop came with no GPU in it, however I have a GTX 880m that fits it's MXM slot. I am a new to techinferno - what brought me here is an issue with a Precision M6700 I bought myself lately.
