please do the following:

This Works for all version, like Neptune 2/X , NP9170 , P170EM etc..
(NOTE : If you have P170SM/SM-A this is NOT the same bios nor the same EC )

Please flash your BIOS and EC to a normal version instead of Prema.


EC: **removed old links** ask me if needed
BIOS: **same***

Make a bootable USB using RUFUS https://rufus.akeo.ie/
Then make a folder name EC on the USB and extract the EC to it

I am putting this here, because there have been a dozen people every week or so, with this issue, and this is how we solve it every time.

 

No stock version does detect a 9xxM, has P'n'P driver support or even works properly with latest driver...Prema Mod Partner shops are NOT using the public v2 BIOS.
Eurocom and other have received special BIOS Mods for this very reason...

 

So, wait, the stock bioses are fine, right ? Okay that's what I understood too. but the issues were only resolved with the EC, and the bios. So maybe it's just the EC then, or are you saying it is the "special" bioses people are using that do not have the support ?
I just wanted to help a bunch of people who obvious look for this information, and do not find it anywhere easily, and keep coming to me for it.

 

To have Plug'n'Play support with BIOS detection, proper GPU switching and performance we need to use the v3 Mod.
No stock BIOS and EC version can provide that to the user...

 

Ah, so essentially what is making everything work, is some v3 handy work then ?
Hence my later revision bioses and EC's listed, right ?

 

It's the same old base the Mods use...sadly they never officially supported any GPU after the GTX680M on the EM-series...

 

Ah, well now we know.

 

Indeed the latest officially supported card was the 680M in this machine which can make the odd driver issue pop up even with a mod.

 

For those looking for this info, just giving thread a bump as it was relevant recently.

The links might not work anymore, if needed let me know.
