Try running your laptop in legacy mode ( not uefi )

Do some training on older gpu and if you succeed then you can try with P4000.

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

180w on mxm card is crazy 😅 even 150w was high but 180w is extreme high 🙃 I know that your temps are low but this will damage your card ( maybe mosfets ) 🤔 I suggest not to go higher than 165W limit. This card is expensive, no point in killing it for few extra fps 😎

Last update. 😎 My laptops TDP is 180W so after some thinkin I made one more vbios. This version is 122W. Should be safe for my computer in longterm ( 122W gpu + 50W cpu ) I also rised slightly max core clock to 1772mhz. Extra 10W will help to stabilize clocks to stay above 1700mhz. I also must say that I applied liquid metal to cpu and gpu. This is risky and could burn your laptop if you dont know how to do it properly. Max temp are about 75-76 degrees. In nvidia driver settings I locked max FPS in games to 50. I dont see difference between 60fps and 50fps. Its fluently and it lowers temps on my gpu. Now my temp are closer to 70 degrees. This is my workaround to undervolt 😉I used this table 😅 240 FPS: target frame rate for extremely competitive gaming that requires fast reflexes 144 FPS (eSport quality): target frame rate for competitive eSport games like LoL, DotA, and CS:GO 120 FPS: Very good and difficult for the layperson to distinguish any frame rates higher than this. 90 FPS: Target VR framerate as to not feel dizzy 60 FPS (Gaming PC quality): Target FPS for most games. Buttery smooth. 50 FPS: Pretty good 40 FPS: Acceptable. 30 FPS (previously console quality): Noticeably less smooth, but still playable 25 FPS (movie quality): Barely playable. 20 FPS: Very difficult to play and frame rate may prove to be a significant handicap in games. 15 FPS: what is this sh*t 10 FPS: PowerPoint is opening skyrim.pptx 5 FPS: PowerPoint has failed to open skyrim.pptx 2 FPS: Microsoft Word? I am really happy to know that I have the fastest P4000 mobile in the world 😅 graphics score is above 5200pts in time spy. Yes I will upload this vbios 🙂 I decided to make second version. Tested 122w vbios for over one month and all was working ok but in long term I would prefer slightly lower TDP and lower temperature. So made some small changes and I give you 121w version. Update 11.10.2024 And again one more vbios with slightly lower max clock 1759mhz and TDP 120W. I think this is sweet spot. If you dont go over 80 degrees this should be good to go in long term usage. Higher clock would need TDP above 130w+ and this will likely damage your card after 1+ years. No point risking going above 120w. P4000M_OC120W1759.rom

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 😅

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.

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

When you run furmark thats normal that your gpu is dying 😅 Furmark is laptops gpu killer, mosfet killer. You could survive with low TDP but if you for example flashed 150W TDP vbios then its good bye after short time.

Buy ch341a programmer with 1.8v adapter and try using @mobil vbios from imac forum 🙂

Welcome, Someone has skills to unlock or find voltage values for this Quadro cards? I tried using msi afterburner but voltage curve is not working. There is no problem with that on normal GTX 1060m or higher. Its vbios locked on P4000 mobile. We need someone with hex knowledge to find where is voltage curve located, where are voltage values and how to unlock voltage on Quadro Pascal mobile cards. Me and Mumbles succesfully flashed overclocked bios for P4000. He did it on Alienware and I did it on MSI gt70. Only thing left is to undervolt. People help 😉 -

I also try to flash any custom bios for my P4000 mobile. I did try nvflashk but it failed propably because my bios is unsigned. Is it only option to use ch341a?
