VAIO Z 330M - How to permanently Flash Overclocked settings?

I am trying/wanted to flash the overclocked settings onto my 330M just like I always do with my Desktop nvidia counterparts. But I was unable to do so because nvbios couldn't read the 330M's bios. I think it said unsupported or unknown card over the course of each time I tried.

Has anyone flashed their 330M bios? The reason I do this is because evga precision, or any other tool doesn't always work correctly with the hybrid graphics setup. Sometimes the overclock won't register because the Stamina mode was on. I just want to uninstall all overclock tools and just have it run on my settings which is 550c / 1250s : 1000m from the stock 450/990:700 that sony used for the Z13.

It Has to be possible. please shed some light thanks!.

 

I think Thomas.idk is running his Z with only the Nvidia card on (and thus using unmodified Nvidia drivers). In any case, with you being on stamina... you realize you're on the IGP right? and that's why you cant OC your Nvidia card... because it isn't even on. Also, I dont know if it's a software lock or potentially a hardware lock, but you cant OC without having your laptop on AC power.

 

Hi. Thanks for responding. I think you may have missed my point though. Basically what I want to do is mod the BIOS of the 330M card itself, so that my overclock will always be set to the custom overclocked settings whenever the graphics mode is set to Speed. You see, for example, if EVGA precision is used, and i start up the computer on battery, or it's manually set to Stamina, then evga precision won't run and the overclock won't register due to exactly what you stated above. Thats why I want to mod the BIOS of the 330M. So that it's default clocks will be what I wanted, without any software.

For example. On my desktop computer, i modded the bios for the 8800 GTS 512 so that I never have to run evga precision or any overclock tool again, as I have already determined my best settings and 'baked' it into the bios, so that even if I re-install, or run another operating system, the overclock is still in effect. I was unable to do that on the 330M though. Apparently the same tools I used could not recognize the 330M in particular, and isn't listed on their supported hardware for nvbios.

So i'm looking for a way / new tool to accomplish exactly this. I also understand that it will create more heat and suck more battery. So I primarily run only on the IGP and only switch to 330M when I want to run demanding games or 3d applications. I always do so on AC power anyway since battery very swiftly depletes in that setting.

Thanks again for responding.

 

You may have better luck with the nvidia bios extraction/flashing tools if you do a few things first. 1.) Enable advanced bios settings (there's a thread on this). 2.) Go into advanced bios menu and set the VGA switching policy to Static. 3.) Reboot with system set to "speed". This will totally disable the intel graphics and "hopefully" allow your nvidia bios tools to be able to go to work.

After that, you're on your own Hopefully your machine is under warranty still.

 

Thanks for info. I know about that thread and the Insyde bios hack but I was hoping I didn't have to go through all that. And another thing I am wondering is if someone who has already done the Insyde bios hack to verify if they can dump their 330m bios from that point.
If that works, then i'll definately mod the Insyde bios. Yeah this computer is under warranty. Just bought it in december 2010.

 

I too would like to find out if this is possible!
I recently o/ced my Z and I got a 25% increase in performance as I posted here

 

I tried NVFlash/NiBiTor procedure with my Z11 on static switching policy/Speed mode on and it didn't work. NVFlash (most recent version) found the 330m but could not read the 330m's BIOS. I run dynamic switching mode in windows and changed that only for the DOS flashing/BIOS dump routine.

Maybe someone running their 330m in static mode can try to extract BIOS in windows w/ GPU-Z.

Ill post the error screen later bc I dont have my mobile phone laying around here atm.

 

It`s possible it can`t read since the Nvidia bios is integrated into the motherboard bios.

You can try using something similar to the Phoenix Bios Editor (Not sure what program can read motherboard bios of the new Z) then edit it with NiBiTor to change the default clocks then reinsert into the main bios and flash. It has been done before on SZ series laptops (But ultimately hastened the death of the Nvidia GPU).

I really can`t recommend hard value changing clock values for overclocking on the expensive thin & light Z laptop for a few extra FPS. The new Z series SPEED performance is allready a huge jump from it predecessor, asking for more could be trouble on its current compact cooling/heatsink design.

Tried GPU-Z to get the bios in Windows XP but no result. (VPCZ12)

 

If the vbios is integrated into the system bios...even if we can get the Nvidia tools to read the vbios...I think it's highly unlikely we'll be able to get it to flash correctly. I think you're stuck with overclocking software...

 

I have an idea. Does anyone know how I can go about running or executing an application when the power scheme is set to SPEED? That way, i can execute the overclocked settings when the nvidia graphics is activated, each time.

I currently use nvidiaInspector which can save the oc settings as a shortcut file. Opening the shortcut, It opens the program silently, executes the overclock and quits.
