Saving BIOS on GPU-Z: Strange Error

[SyniKaL]

Hello,

I'm trying to undervolt my nVidia GT 525M (for which i've heard good undervolting results) and i'm running into a problem on the very first step that no-one seems to have encountered before.

Every time I try to save my GPU BIOS (through GPU-Z 0.6.6) nothing happens for about 3 seconds followed by 2 very short high-pitched sounds followed by an error message: "C: /Users/User/AppData/Local/Temp//nvflash.rom was not found".

When using an older version, I get the instant message that says "BIOS reading is not supported on this device", but I know it is because it's been done several times on this particular card. My nvflash works normally, but I fail to see it's relation with GPU-Z and so why I get this error message.

I don't think specs are relevant here, but i'll just say that i'm on a laptop with an i7 processor running Windows 7 64-bit

Any ideas appreciated. Thanks in advance!
Syn

Sorry,,I may have misunderstood. If your trying to save the Modded Bios.

one of the winflash's or a Bios editor??

Well there You go, I was Wrong Yet AGAIN.

If the GT 525M is soldered on the motherboard and not on a daughterboard, the BIOS is likely a module inside of the main system BIOS. Most laptops that have non-replaceable GPUs do this.

gpuz uses nvflash to save the bios on some cards

if you are able to use nvflash on your own, from the command line, do that if you experience problems

I tried doing it through the nvflash command line ("nvflash --save bios.rom). Funny enough, I get the same 2 high pitched sounds before I get an error.

Here's what it says (I had to printscreen and paste this since the message goes away so fast):

Identifying EEPROM...
EEPROM ID <20,0000> : Unknown

ERROR: Supported EEPROM not found

Clearly this is the reason for the original error. Any ways around this?

If you're using the latest version of nvflash, the card probably doesn't have a dedicated EEPROM as I mentioned above.

Ok, so is there a solution? I tried different versions to no avail.

If, as you say, my GPU BIOS is a module of the main system BIOS, how do I access/save it? How do I flash it?
