GPU GT365M Optimus

Recommended Posts

Hi, I'm Jonathan from Italy!!! I've a problem with my new Lenovo Z580!!! The Optimus Nvidia don't work...

 

In the Nvidia panel I select the Gpu Gt365m (or with right button on the .EXE and select "use performance Nvidia graphic), but when the software (or game) start, in the menu I can to select only Intel HD4000!!!

 

The Gt365m is activable only I link a monitor VGA (with hdmi ever function the HD4000)...

 

The original driver Nvidia are 305.43, I update at the 314.07 but the problem is the same...

I start the original backup of the notebook, but the problem is the same...

 

My O.S. is windows 8 pro 64bit!!!

 

On the Nvidia panel, I have only a voice "3D Settings"...I've not the voice "video"!!!

 

(In the Bios "Optimus" is active)

No wonder, GT 365M is a really odd one, haven't seen it so far. But seems to exist as some web page claims it (or is it 635?). Most Z580 models seem to have either plain HD4000 or coupled it with GT 630M. You should find your hardware IDs so your card might be added.

314.14 does support these Lenovo 635M cards - is yours a different one by the device ID?


[DEV_0DE3&SUBSYS_390117AA] NVIDIA GeForce GT 635M
[DEV_0DE3&SUBSYS_390217AA] NVIDIA GeForce GT 635M
[DEV_0DE3&SUBSYS_390417AA] NVIDIA GeForce GT 635M
[DEV_0DE3&SUBSYS_500117AA] NVIDIA GeForce GT 635M
[DEV_0DE3&SUBSYS_500317AA] NVIDIA GeForce GT 635M
[DEV_0DE3&SUBSYS_500717AA] NVIDIA GeForce GT 635M
[DEV_0DE3&SUBSYS_501217AA] NVIDIA GeForce GT 635M

 

The modified inf seems to be missing GT 635M so far.

Just like the GT 630M is a higher clocked GT 540M with better media decoding, so does the GT 635M is a higher clocked GT 555M with the same improved media decoding.

 

What games are you trying to run that don't recognize the Nvidia GPU and only the Intel IGP? Also, it's important to note that many games only list the Intel IGP but actually do run on the GPU.

 

I can say that 310.90 drivers are working flawlessly on my Optimus system (HD 3000 + GT 555M).
