Quadro P4000 Mobile Oc vbios. Working and tested.


Recommended Posts

This is vbios that I found on imac forum and made my changes to rise overclock of core and memory. Thanks go to user @m0bil for making imac vbios version. 

 

After my changes overall performance boost is about 30%. Its close now to gtx 1070m.

 

Tested on MSI 4th gen laptop running in legacy mode and it scores about 4900-5000 pts in timespy graphics score. I have P4000 dell version card.

 

Vbios is only for P4000 mobile with 8gb ddr5. Do not try flashing on other pascal cards.

 

To flash this vbios you will need CH341A programmer with 1.8v adapter.

 

Some info:

- core clock set to max 1747mhz and max voltage is now 0.95v

- memory clock set to 1752mhz

- TDP set to 112W

 

Core clock set to 1759 is using 0.975v so I decided to stay on 1747mhz. Higher memory clock is not working so its locked on 1752mhz. TDP set on 112w is to protect card from damaging mosfets.

 

I had to modify inf in latest drivers for my MSI and enable test mode in windows to install unsigned drivers. My max temps are about 75-76 degrees (fans full speed)

 

I dont recommend using mosfet killer apps like Furmark with this vbios. 😅 You have been warned.

P4000M_OC112W1747.ROM

 

 

Thing to do in the future:

- enable undervolting

- find where are located voltage values in vbios

Thats pretty amazing for a P4000, my RTX 3000 got 13301 (https://www.3dmark.com/fs/31222747) in my m17x r4. And thats my HIGHEST score! Does this vBios open the Overclocking ability? If it could be OCed it could beat the RTX 3000

I like the vBios version DEAD 00 BEEF, memorable name for vBios. Nice Job

There is no option to change clocks and undervolt in windows. This is bios locked and I dont know how to unlock this using hex editor. With unlocked undervolt I would try to set 1900-2000mhz. Maybe someone in the future will find how to unlock undervolting 😉 My clocks should be safe to use in longterm. I dont recommend higher clocks without undervolting.

Did some modding 😎 I added two small fans. Size 40mm x 40mm x 7mm. There was not much space but I was lucky and made them fit. I hope that one in the center will help to cool down my gpu mosfets. Had to cut down some plastics from bottom cover. I converted fans to usb ( they are 5v ) and will simply connect them to usb port.

 

Time to test TDP 122W and core clock 1797mhz and see how it goes 😉 maybe nothing will blow up 😅
