SuperMG

DP/DP/HDMI/eDP. Same as the RTX 4070 MXM. Works perfectly fine on my M6700 and 7720. I had all the display ports, even the USB-C on the 7720.

I have a Dell Precision M6700 Red Covet with RTX 5000 16GB if you want with the 120Hz 3D screen. No fan problems and the RTX 4070 and 4080 worked in this laptop with the backlight mod.

For Aetina it was the case for their Ampere and Ada cards. Maybe PCP is using the same VBIOS as Aetina? For X-Vsion it's different. I saw the GPU-Z screenshots and the GPU was outputting in DP without 4G decode enabled in the SBIOS.

It's already longer because of the newer design.

Hello everyone! Do you want to upgrade your old laptop MXM GPU? But you can't since the newest RTX Turing, Ampere, Ada and Blackwell won't work with your eDP display? I have the solution for you! No more blackscreens! The backlight mod v2 upgrade to enable eDP display for your MXM card! Here's the old thread for the backlight mod v1: Every cards from Turing to Blackwell generation, from brands like Aetina, Adlink, PNY, ZRT and X-Vsion will work with this mod! Thank you to everyone who bought the backlight mod v1! I have sold everything! The backlight mod v2 will offer BRIGHTNESS CONTROL thru a tiny PWM module that you can install inside your laptop's case or in the SSD/HDD 2.5" bay or directly outside the laptop. (Backside of the PCB is insulated) How to control it? With the small knob, you can directly control the brightness from 1% to 100%! The v1 was stuck at 100% because 95% of the laptops I tested lacked the PWM brightness module in the motherboard. Only the Clevo P570WM3 had brightness control with the v1 mod! The flex FPC cable is longer than before! From 7.5cm to 10.5cm! Why? To allow easier installation! It's now way easier to install the V2 than the V1. Signal 23 and 25 are the same, nothing changed there. Available: NOW! You can order in my private messages. No SOLDERING NEEDED!! What's included in the package: 1x FPC cable 1x PWM Module 1x 15cm cable for connecting both For people who already bought the v1, I'll include 2x FPC cables for the same price! Compatible with GPUs: Nvidia RTX 4050, 4060, 4070 MXM-A (ZRT, ENBIK, X-VSION) Nvidia RTX 4080, 4090 MXM-B (ZRT, ENBIK, X-VSION, need EDID override because the drivers disable the eDP, which results to a non-PnP screen in windows) NVIDIA Quadro RTX A5500, A5000, A4500, A4000, A3000, A2000 MXM-A (X-VSION, for Aetina, PCP, you need 4G decode enabled in the SBIOS) Nvidia RTX 3050 Ti, 3060, 3070, 3080, 3080 Ti (X-VSION, ZRT) Nvidia RTX 3000, 4000, 5000 (Aetina, PNY, ADLINK, PCP). Compatible with laptops (v1 tested): - eDP screen (eDP/DP in DP_D port) - Enable pure-UEFI in SBIOS - Legacy Options OFF - Optional 4G Decode enable in SBIOS for Ampère and Ada cards from Aetina, PCP, PNY... (EDP) Dell: Precision M4700 and M6700 Precision M4800 and M6800 Precision 7710 and 7720 (EDP, needs testing) Alienware M17X R4 (120Hz), Alienware 17 R1 (120Hz). Will not work with M17X R3 because the SBIOS doesn't have UEFI and the newer RTX cards must need UEFI in order to display with the DP protocol. (EDP) Clevo: P570WM3, P870 series, P775 series, P770 series, P750 series, P375SM, X170 series (MXM based laptop and eDP screen but it needs substantial heatsink mod, no one tried on this pc yet) (EDP) HP: ZBOOK G4 17, G5 17, G6 17 MSI: I don't know which models use eDP (probably the Pascal models) but... A lot of users report fan control issues with RTX MXM cards in LVDS Switchable Graphics based systems, so I don't know about their compatibility. Some sneak peek: Installation may vary, you have to cut a small part of your heatsink if your heatsink doesn't sit flat. Cicichen makes compatible heatsinks.

The risk is that these cards must need 4G decode to work on + they're crazy expensive for what they are. Yes they have DP on DP_D and I don't think this will fix the "EC fan controls".

It's a DP_A, how can I receive its video output? Any receiver for SiBeam?

For the GPU: Yes that works but it's better to use AMD HD 7970M/8970M + RTX 5000 with registry edits on regedit. You won't have any TDP issues (issue was: stuck at 70% max). SBIOS depends since there are 2 motherboards revisions for this laptop. LVDS + eDP.

Hello, here is it: https://winraid.level1techs.com/t/guide-remove-uefi-image-from-nvidia-vbios/34363?page=1 or ask ssj92 for the help.

I had a 3080 in a SG and I was getting 9100 score in TimeSpy, The same card with the same settings, got me 11500 in dGPU eDP. Even on my RTX 5000 Ada with iGPU on, I was losing 10-15% performance, Dell Precision 7780. eDP is preferred because you can upgrade to better displays (not in M6800) and it's in DisplayPort standard with full dGPU performance. dGPU > SG

Yes but not recommended.

No they don't have backlight pins.

I found the MUX switch schematics, it was in the M17X R4 schematics. The MUX doesn't require any backlight signals in the input. Maybe the screen directly communicates to the laptop about the backlight not being on.. The MUX is just a basic DisplayPort Mux which works in desktops and laptops. For the A4500. Yours is from Aetina which needs 4G decode to be enabled in the SBIOS, otherwise it won't post. They can potentially work in the newer HP and Clevo laptops if the 4G decode is present. X-Vsion sells very cheap A4500 and A5000 both are working without needing to have 4G decode to be enabled. The CEO showed me proof. The ReBar and 4G decode were disabled in the SBIOS on the GPU-Z screenshots. Same for the A5500, which is the one I bought. 7424 CUDA cores, DP in DP_D, 16GB VRAM, 115W VBIOS. I'll test it in the dirt cheap Alienware M17X R4 32GB GTX 680M I bought. I'll upgrade the screen and LCD cable to eDP one and use the backlight mod v2 cable. Sadly I didn't receive yet the LCD eDP cable nor the backlight mod v2 cables...

I saw in the schematic of the R3 and R4 that there's a DP_A but it's not a regular video output. It's a wireless HD output from the DP MUX switch, it's going thru the DMC module, 05XHG5. Did anyone try the wireless HD in an external monitor?

Did you try without GOP/UEFI partition of the GPU?

Hello. Did you try M2000? M2200? 965M cards on it? They can work because the K2100M is Kepler 2 which is a newer structure and it isn't compatible with my Clevo X7200 in the master slot but the K2000M is...

Do you have 16GB DIMMs? If the BIOS works and the RAM too then I'll flash

No I don't run, I wait for others to test it.

So it's a Prema mod one but modified? Clean ME region? EDP compatible I suppose, it says 120hz on his tweet

Hello. Where did you find this? What module was updated/edited in UEFI tool? Thank you

So with HDMI in DP_B, I can output to DP thanks to the DEMUX from MAX? There's a DEMUX + DP Redriver. Max doesn't state any HDMI in and no dual-links too 😕

When is the ETA to see which video port is which video signal output? A to E ports. So I can test them with my VBIOSes. Very important for DP_D I bought a Quadro RTX A5500 from X-VSION. It has simple DP in DP_D and can work without having 4G decode in the SBIOS. I want to know if the DP_B is really an HDMI or a DP...

Tell him this for the P570WM: The only mods I did, was to get the Prema BIOS, make a backlight mod cable FPC for RTX, add the RTX 4090 MXM and make a modded custom heatsink. Can he come to this forum please? I need his BIOS for the 64GB RAM!! Clean ME bios of course. Normally the X79 and X58 chipset support 16GB DIMM per slot. But the BIOS limited them to 8GB DIMMs.

Do you have any benchmarks that prove the point between them? A5000 (3080 115W) and A5500 (3080 Ti 115W)? It's 550USD vs 650USD... I forgot, is your Pascal VBIOS in UEFI or Legacy only?

But could it be possible for the software to sort the Display tables? To know which is A, B, C, D and E?
