Flashed the bios of gtx750ti, no increase in volts.

[doomed2fail]

I'm new to the tech game, I've got a learning as I go kind of thing going on. I want to get the most out of my graphics card so I flashed the bios. But there has been no increase in volts and I don't know if it worked or not.. I think it did it right because I got the beeps when I flashed it. I followed a guide to using kepler bios tweaker and then downloaded nvflash. I accesed the command prompt from within the folder contained nvflash on the c drive. I saved the new bios as "bios2.rom". In the command tab I entered "nvflash -4 -5 -6 bios2.rom" then I hit "Y" when prompted, got the beeps and restarted the system. however gpu-z is still show the cap of 1.6 volts.

 

 

I believe the flash took though as when I tried the same input prompt again in the command tab it came up with an error saing it can't open the file. presumably because I was trying to flash the bios with the existing version of the bios?? I have also tried the command "nvflash bios2.rom --overide -6" same error message.

 

Anyway I attached some screenshots which should show more.

 

Also just a quick question on how to know when you've hit your max overclock

 

I just steadily increase clock speeds with msi afterburner and run heaven benchmark. I stopped when the heaven score starts declining. My logic is that when the score starts declining it's getting worse... I've no idea if that's smart though. let me know thanks.

 

So pic 5 gets 608 on heaven with everything maxed and in fullscreen. but I still get the same performance cap as when I max out the voltage as seen on pic 3. So I'm hoping that by flashing the bios I can increase the voltage more than in pic 5 and maybe bump that score up a bit.

Did you change the voltage tables in the BIOS?

 

More than likely you have a voltage limited card, and will need to solder off resistors on the PCB to get rid of the limit.

No I didn't change the voltage table. The guide never said anything about that. I'll get right on that, cheers man.

Flashing a card doesn't guarantee you'll get any higher voltages at all. It's a matter of luck. You'll know you went too far if the card starts overheating or artifacting.

What settings did you change in KBT? (also does KBT even work with maxwell? as i was certain that they released a new version for maxwell cards)

I have no idea. Is there somewhere you can download a preset modded bios?

[doomed2fail]

So that's the error message I'm getting. Any ideas how to fix it?

Got it sorted btw. If anyone is ever looking at this going "what the hell is the answer" you need to go over to overclock.net and download a version of nvflash which has Certificate Checks Bypass and that will do it.
