Code 31 and some other problems
i've got some weird things right after i managed to do the dsdt override. Loading from the setup 1.x after doing a 36 bit compaction (which i assume i should be doing since as far as i see that is the whole point of getting the dsdt override) i get the windows logo and instant freeze (no hdd activity and no bluescreen). If i let it boot without loading from setup 1.x it boots normally, but then i get the error code 31 with "The driver trying to start is not the same as the driver for the POSTed display adapter." on the basic display adapter (eGPU) and the external display is in standby. Nvidia drivers fail to install with something about no graphics hardware found.
Can you guys think of something that could be done or maybe anything i did wrong?
dGPU: Nvidia 9600m GS
eGPU: Nvidia GT640
OS: Windows 8.1 at the moment but can be anything if there is a better chance of working on another OS
Link is by expresscard
And before anyone says it.. yes i know this laptop is old and i know that having no iGPU for optimus and the x1.1 expresscard will slow it down, but as i have the hardware either way i might as well try to make it work.
Hi,install windows 10.
1. go back and find the last driver that suport your dgpu and your kepler based egpu
2. disable your dgpu from device manager(will remain with windows basic display adapter,enough for booting)and install the last nvidia driver.It will ignore your dgpu and recongnize only gt640.
Previously use DDU uninstaler.
Disable automatic update if you are using an old driver in windows 10.
Here you have an old driver that suport both cards(not sure if is the last): http://www.geforce.com/drivers/results/73216
Thank you for the link, that driver works very nicely. No more errors or anything.
I've got the same Error 31 but other Hardware.
12 GB Ram
6770M / HD 3000
EXP GDC Beast V 8
zotac 1070 TI
Corsair 750 Watt PSU.
at the beginning there was just a "unknown Device" then i've installed the drivers individualy and now it shows me the 1070 ti at the Device Manager. But with the Error 31.
Is there a special Driver for the EXP GDC or have I switched it on?
