I recently upgraded my Dell M6700 from a Quadro K4000M to Quadro M4000M and I am experiencing an odd problem. 

The GPU no longer is able to detect monitor resolutions or specifications past 1080p 60Hz. 

I have a Sony X900H TV (4k and 120hz capable) as well as a 3440x1440 144Hz UW monitor.

With the K4000M GPU I was able to max out the HDMI 1.4 specifications (4k@30Hz, 1080p@120Hz, 3440x1440@45Hz). 

Now with the M4000M, I am unable to do anything past 1920x1080@60Hz.

Forcing custom resolutions in Nvidia control panel causes displays to bug out. I think this has something to do with the modified INF drivers? Or maybe the GPU is limited in this laptop?

If anyone has any experience with this, please let me know the fix. 

Hi @Klem , 

I have a stock M4000M vBios that I would like to have unlocked (past +135 on cpu core, and memory frequency unlocked).

Here is the stock vBIOS : https://www.mediafire.com/file/n7myjsx0s9nxsj6/GM204-M6700.rom/file

Really appreciate your help! Thanks again.

Two variants, +50mv one and a +75mv one.

Mod75.rar

Thanks! I tried them both but I didnt get any extra overclock out of it (still stuck at +440 core , +730 memory) but i did notice something very odd. 

I used to use HWINFO64 to get the GPU voltage , however now with the new VBIOS you provided, I get blank info for the GPU sensors . No voltage. I cannot tell if it is actually increased or not??????

Post here your vbios.

This one, the K4000M OC one, just with a bit more voltage pushed to it, maybe a  +50mv one and a +75mv one ? I'm not too sure about what is acceptable on Quadro cards.

Thanks.

Any chance I can get the K4000M vbios with an increased voltage bump? +100 or 150mV? I have a ton of temp overhead and want to squeeze more out of it. Or if you could direct me to a method/tool/tutorial where I could do the modification myself.
 

Thanks a million.

Updated my Dell M6600 from a Quadro 3000M to a K4000M, and flashed the custom bios from svl7.

WOW what a huge difference with that overclock limit removed, went from

Core: 601MHz stock to 1045MHz stable (+444)

Memory: 1400MHz stock to 2150MHz stable (+750)

Any chance someone can mod the vbios to include a voltage bump from say 0.962v to 1.05v? My GPU is topping out at 65 Celsius (just repasted) and id love to try to push more out of it (maybe 1100 core?! )

Thanks a ton.

I just purchased an M6600 and it seems like from what people have been swapping you are restricted to GTX 6XX series, K3000/4000/5000/5100 and ATI 6XXX / FirePro 6000/6100/8900

Ive had some good luck with arctic silver mx5

A mix of corsair AF series fans and Antec TwoCool , all 140mm

Hey everyone, just got a Dell M6600 super cheap and looking to use some modified VBIOS files

Personally, I have not noticed much of a difference

Just got an M6600 with a K3000M, cant wait to flash the custom vbios and see the sucker fly. thanks for all the hard work
