jensen Posted December 24, 2015 Share Posted December 24, 2015 Hi, I have a sony vaio vpcf12hfx (i7 720, GT330m, express-card) running windows 10. I've managed to get it working with a GTX 750ti using a pe4h v3.2. The egpu works fine however the GT330m gives an error 43. When I boot without the egpu connected, the GT 330m still doesn't work. I'm guessing the 750ti drivers don't play nice with the 330m. Is there any way to fix this? Link to comment Share on other sites More sharing options...

Means you choose a driver for one or the other with whichever being excluded being the one that has an error 43 against it. The most recent GT330M is a 'legacy' 341.92: http://www.nvidia.com/download/driverResults.aspx/94790/en-us Link to comment Share on other sites More sharing options...
jensen Posted December 24, 2015 Author Share Posted December 24, 2015 Thanks for the info. How can i find out what gpus have a unified driver with the 330m? Link to comment Share on other sites More sharing options...

Click the 'supported products' tab when viewing the GT330M driver. The laptopvideotogo website did some mods to incorporate mobile and desktop drivers. Worth having a look. You might find an older GTX5xx or GTX6xx can be paired with a GT330M using a unified driver. Link to comment Share on other sites More sharing options...
jensen Posted December 24, 2015 Author Share Posted December 24, 2015 Thanks again. I'm guessing there is no software that can manage two drivers on the same machine? Like selecting at boot time which driver to boot with? Link to comment Share on other sites More sharing options...

Also would getting an amd gpu instead of the 750ti fix the issue? Link to comment Share on other sites More sharing options...

jensen Posted December 28, 2015 Author Share Posted December 28, 2015 (edited) If anyone is interested, this driver seems to be working for both cards. The real challenge is getting windows 10 to stop overwriting it. https://www.nvidia.com/download/driverResults.aspx/82467/en-us Edited December 28, 2015 by jensen 1 Link to comment Share on other sites More sharing options...

Can use "DDU" software to disable Win10's automatic driver installation. Then you can install and keep your linked older 341.11 driver. Link to comment Share on other sites More sharing options...
