Sony Z11 - NVIDIA Optimus

Good news, gtx 750 egpu works nearly flawlessly with windows 10 64bit Pro!

Installation Procedures:
1) Static mode selected in BIOS. Tri-switch set to STAMINA.
2) Install Intel driver or wait for windows 10 to download it. Then restart.
3) Download nvidia 353.62 windows 10 drivers (Or wait for Win 10 to download them for you in the updates). EDIT: Installed Nvidia 358.50.
4) Put laptop in sleep mode.
5) Plug in egpu. Then wake up laptop.
6) Install nvidia drivers. Restart may be required.

Note: I haven't tried installing the gt330m or Nautis drivers.

Usage:
1) Put laptop in sleep mode.
2) Plug in egpu.
3) Wake up the laptop.
4) Go to device manager > display adapters.
5) Disable Intel adapter, then re-enable it. Somehow, this activates directx 11.
6) Go to the Nvidia Control Panel and in 3D settings, make sure that the nvidia gpu is selected for the application you want to run.

EDIT:
7) To get the brightness keys and vaio buttons working. Open Windows Services and restart Vaio Event Service.

Playable:
GTA V - set Vaio power management to Silent Mode for cooler temps (78~83C). Graphics options set to High. MSAA off. avg. 30-35fps internal screen @ 1376x768.
MGS V - Flawless. 1920x1080 @ High. 30fps.
ANNO 2070 - 1920x1080. High. 25-30fps.
EDIT:
Diablo III - Works with NVIDIA 358.50. 25-30fps internal screen, High Settings, AA enabled @ 1920x1080.

Something that i always wanted to try, disable intel from device manager, install nvidia driver without optimus.

Not everyone know how to differentiate optimus, but here is the way, when you open infs, fisrt search for 330m, then copy the 0a29 and use it to find 0a29 upward then look at the section, section003 for example, then search [section003] any optimus mentioned? If yes that is optimus driver, if no means you can edit the 0a29 to 0a2b or add. This is simple explanation on how you edit a driver.

So tell me if disabling intel will let you install nvidia only.

 

My thoughts on this:

1. If you look at the Z1 block diagram, the LCD and VGA ports are connected through the Intel chip. Only HDMI is directly connected to the NVIDIA chip.

2. I now have the BIOS hack and am able to use one display adapter at a time (throw the MODE switch to the desired position and reboot), but if I try to install the NVIDIA driver in SPEED mode before installing the Intel driver, NVIDIA driver setup tells me to install the Intel driver first.

Hope this helps. Keep up the good work.

 

I see, so the only way is to use bios hack method so we can install windows 10.

I have autohotkey to make my own brightness slider using ctrl and brightness button, of course gui is not that beutiful but works.

 

No, no. There are people here who have installed your hybrid driver successfully. There is just one additional step needed - to prevent Windows Update from installing a newer driver that doesn't work. You have to hide that driver update.

 

Nvidia Driver for windows 10
not hybrid
not optimus

How did you install it? BIOS hack? Static mode? Which Intel driver?

If you managed this without resorting to the BIOS hack and everything works (HDMI, VGA, etc.), then this is great for those who don't want to do the BIOS hack thing.

I'm running 341.81 on Win10 with the BIOS hack and VGA switching mode set to STATIC in the BIOS. Everything is just peachy, but the BIOS hack took a lot of nerve.

 

Yeah anytimer, bios hack, but i always think i can disable intel and install this.i have brightness control working, what is your experience?

 

Ah! I have the BIOS HACK too. If you don't install an Intel graphics driver in stamina mode, when you try to install the nvidia driver it will tell you to install the Intel driver first.

 

let me clarify, I always use static mode, speed mode, I don't have intel driver installed, nvidia didn't ask me to install intel, i am having full option in nvidia control panel, not optimus option.
