Nvidia-vBIOS-Clock-Power-Tweaker - PASCAL TESTING NEEDED !

[xing0999]

I bought a graphics card for 50usd, it has a p4200 mobile gpu chip, will your tool work?

Windows is very insistent that v1.3.4 has a virus in it.

 

Also, do you have a way to effectively shift the frequency/voltage curve like normal overclocking? Ex: Can I offset clocks by +150MHz, or does setting a higher core clock just pick a higher frequency/voltage point?

Yes it happens with unsigned exes. You can download the source code, download python 3 and run CPR_MAIN.py and it will run the code directly without going through the packed exe.

I see what you mean. 

 

The way the program works is by allowing the card to reach higher limit clocks. Meaning it will figure out the frequency/voltage points. 

 

It's not like msi afterburner's clock slider that uses the same voltage points but for higher clocks. 

 

For example, my p4000 stock vbios gave a maximum of 1240mhz @ 0.750v

After the overclock from my program is applied it reaches 1898Mhz @1.050v.

 

Unfortunately I doubt I will be able to obtain voltage control, I only found one person talking about voltage points and I could not find correlations with the clock table.

Very nice, with an overclock you should get >1070M overclock levels of performance! 

 

Yes, I saw your post on techpowerup. It should work. If it doesn't send me your vbios and I will take a look.
