M4800 Owner's Thread

Just a quick reply, got an idea while watching tv..
MSI uses this panel on GT52, GE60 and GE63.
I searched for drivers for GT52 and found a true color 2.7 archive on drivers site:
https://download.msi.com/uti_exe/nb/ap_Install TrueColor20191211binexe_2.7.3.0_0x46f7492f.zip

Your panel part number is N156HHE-GA1 with codename CMN15F4.
In the archive is a folder named CMN15F4 with two files, adj.bin and Backup.bin.
Now the utility wont install on my laptop, it says not MSI hardware and cancel the install.
But its a proof of concept, MSI has a utility with preconfigured calibration profiles for all panels they put in their laptops.
Maybe there are some Spyder profiles or .icm files on the internet you can import?

 

The issue still remains with the lack of 60hz, and I tried Custom Resolution Utility, but that didn't yield a positive result. Flickered at 60hz

Notebookcheck.net had them which was where I found the issue if I use one of these, the screen looks either too red or minimal difference. The GE63VR ICC seems a little better though but I'm convinced with the utility, it improves the panel somehow and calibrating it there makes it even better. Then again my eyes aren't fully adjusted to it yet.

 

mm, our eyes play big tricks, I am not an expert myself on color balance, the best thing would probably be to find a used spyder on ebay or some modern device and calibrate the screen yourself and get hard data to verify accuracy.
A preconfigured profile is only as good as the same batch it was manufactured with, different batches different bins, some may be slightly off, some may have minimal backlight bleeding etc etc

 

What about Dell's Premier Color? I'm not sure if it's possible to install that but I'll give it a go tomorrow...

 

Good idea, downloaded the software from here:
https://dl.dell.com/FOLDER06464896M...tware-Application_47R04_WIN64_5.1.2.0_A00.EXE

Opened the .exe with 7z and opened the appx and I found some plain calibration files, but I didn't find any folder named CMN15F4.
Closest name in the folder is CMN15F6

 

My K2100M broke, had no video when I was going to turn it off when I went to sleep, no video when turning it on..laptop booted fine after I teared it down to bits and removed the gpu.
I had to order some thermal pads for my M5100, installed it an hour ago, prepared a burner SSD to test drivers in Windows 10.
No surprise the correct M5100 driver froze the system, this time Windows did actually recover automatically removing the driver so it would boot again.
Last time I had to boot into a live windows 10, point the system to the ssd and remove the driver manually.
I tried the R9 290x driver that the gpu is identified as, why I dunno...but there are other owners reporting the same thing that the name of the gpu changed.
It runs just fine, gaming is very good.
Unfortunately there are still overlay color glitches in VLC when playing certain codecs like H264 when auto-hiding OSD playback control. There is a slight change in colors when this happens but not as bad with the driver I used before, the old 2019 enterprise M5100 driver from AMD website.
If you move your mouse of course the OSD is brought up and after a few seconds it hides again and this is when the glitches happens.
I didn't test switchable graphics, I just assume it does not work, because it never worked with AMD gpu's, so I simply disabled switchable graphics in bios.

 

That's weird, i'm using the lastest amd drivers (21q1) on my flashed M5100, and it actually corrected issues instead of creating new ones (forza used to crash when loading on last year drivers, not anymore ), maybe your gpu is faulty, or the vram is unstable for god know why...

Also i don't have that issue with vlc, both h264 & h265 (mkv) are fine.

Well for me it does work, but i disabled it anyways because web browsers are using the intel igpu if switchable graphics are enabled (as i'm doing web development, i need the horsepower for openGL, optimisation comes after ^^)

 

I have no idea, I bought it refurb, I googled the part number and it seem to be Dell original part.
Did you flash vbios?
All I remember is that it did report being an M5100 when I bought it but changed name after installing new drivers from AMD website

 

Yes i did, using valuxin's modded Vbios, everything is explained in this thread : http://forum.notebookreview.com/thr...ocking-vbios-mod-dell-precision-m4800.789891/

i ended up with 975Mhz on the core & 1425Mhz on the Vram, so a nice performance boost ^^ (and with arctic mx-4 it never goes over 73°C when in full use)

Well mine is reported as an "AMD FirePro M5100" by both device manager & GPUZ

btw when you swapped from a quadro to a firepro, did you change the heatsink too ? the firepro's die height is lower than the quadro, so your fitment might be bad (although i doubt that this is what's causing problems, i really don't have any other idea other than "partially damaged" gpu / vram / other electronics on the card :/ )

ps : i do remember of a french youtuber having a partially dead i7 : when in 2D everything was fine, but when he switched to 3D, and no matter what the gpu / ram, it was artefacting / missrendering some triangles, assumptions where made that it was the memory controller or the cache that was doomed, but the cpu was still as fast as it should when running cinebench for example)

 

tried flashing both the modded file in this thread and
https://www.overclock.net/threads/bios-flashing-the-m5100-amd-firepro-for-my-dell-m4600.1613976/

I got an error that the existing vbios is newer than the rom I'm trying to flash.
Bypassed this by using amdflash -fv -p 0 [filename].rom.

The system boot up with switchable graphics turned on but blank screen with switchable graphics off.
Removing the cmos battery to reset bios and booting to dos and flashing my backup have my laptop booting up again.
I will conduct some tests with switchable graphics on and see if the gpu is working at all.

System will not boot at all with mod 1100, hangs on loading circle.
System does boot with modded vbios from OP post.
Task manager does not even list the amd gpu, theres a warning in device manager.
I uninstalled drivers with guru3d and installed win10-radeon-pro-software-enterprise-21.q1.1.
Surprisingly it installed without any issues but still after reboot amd software prompts driver is not installed or not working properly.

reflashed my backup and gpu is listed in task manager again....mmm



...o my god.
My gpu is now correctly detected as an M5100!, maybe flashing vbios fixed my issues because I now have the correct driver installed;
win10-radeon-pro-software-enterprise-21.q1.1.exe

Before






After









Even clock speed and temps are working now .
Maybe this little experiment wasn't a waste after all even if I ended up with my original vbios, perhaps I can mod my vbios in the future to overclock it.
Eh yes, I did buy the AMD heatsink for it, I somehow lost my Nvidia heatsink but the amd heatsink had good contact on the nvidia due to the copper plate being thicker on the amd one..It could have killed the gpu I dunno, I did notice a significant performance drop using it, that's why I ordered the thermal pads to switch back to the amd card.
Anyhow, could this week end any better?....eh well VLC glitch is still there...but hey at least the driver work
