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.

Version v1.4 is out, you can now edit pascal desktop cards

Editing the attached P5200 vBIOS with v1.34 of your tool isn't getting me an overclock. If I overclock vram, the 1.5V speed bin gets ignored and it runs at the 6ghz 1.35V speed bin. Raising the core limit over 1708 is also ignored.

 

Currently I'm trying to set 8GHz on the ram. I am using the #2 memory strap setting on the card instead of #0 like every other P5200 in existence. idk if that matters for vbios vram overclocks.
