Hi Nothing special ,bad news of course is that my solution require some soldering expiriences. Basically add new lines from mxm connector where have Gpu DP-out pins to mux switch instead of old LVDS lines . Most important is known on which pins of Gpu is simply DP not advanced DP+ or DP++ ,because in this case the lcd have issue to catch up the high frequency signal as well. For example my chinese Gpu cards (RTX4090 X-VSION and RTX3070 16Gb PELADN) have both DP++ on DP_A,B and simply DP on DP_D, but my Adlink Quadro RTX5000 have DP++ on all DP ports. In this case is necesesary to add between mxm and lcd (retimer, repeater) . You can recognize it that lcd normally work untill install Gpu drivers. After that is black screen. This is not of EDID issues! Maybe ask for help user SuperMG to developing the flex cable to bridge lines from LVDS to DP_D right on MXM conn. for non soldering solutions. I think that will working on Alienware 18 too.

That´s very good idea .Awesome. Maybe will be v2 version in future.

Good work, but for safety maybe could add some schottky diode and resistor for current limitation when anything will be happen. And keep in mind please ,that modification basically work on opposite principle (signal is not from gpu,but to gpu and who knows what can be happen).Maybe this three pins on gpu isolating with capton tape will be good. On almost the same principle also works to switch multiplexers from Lo state (defeault PCH iGpu) to Hi state dGPU thru pin DGPU_SELECT. Who have a eDP platform and not OEM gpu card on the right DP pins on mxm connector is step forward for you. Who have LVDS it must create a new lines as i. For me absolutely best to use ffc cable with pcb connector to modify anything on mxm connector I was use this options ahead at time ago when i convert my AW18xR2 from LVDS to eDP by the way.

Good point. These pins are important. PNL_PWR _EN - enabling power source to LCD PNL_BL_EN - on/off LCD PNL_BL_PWM - pwm duty cycle I think there isn´t nothing terrible to solve it. The first and second maybe will be a TTL logic so level high it is needed (1.8v-3.3v). PNL_BL_PWM - first i try 3.3v = 100% duty cycle

Yes it´s true, but don´t forget please to a Dual Link-Mode of DP-out .

Hi, good work on this . The RSVD pins are a reserved pins for additional equipment of electronics on GPU board, and thru these pins (3,3v) powering them in this case. Manufacturer strictly directions use of them, but not always at the same positions 240, 242 it can be on different pins like 235, 237 and so on. On some time ago i was trying to solve similar upgrade problem on Clevo P177SMA. The result is yes this pins are important ,but modification is not necesesary to be done on mxm side. The connection brigde it can be done on GPU board too. It´s nice to see how much people are interested about this problems and trying it to solved in. Thanks for your help, everyone. Let´s go and never give up.
-
Exactly,thanks.
-
Now it´s Clevo not ZBOOK G6/G5 ? Ok remember please i was write in my previous contribution (there are several pins call OEM ,RSVD and maybe more) is important this means not only the OEM pins in this case. You must be better attention of these diagrams. This is one of many problems too on M18x by the way. Good luck to modify.
-
Ok, but what the other pins of the connector? These pins are´t controlling via mxm card.
-
Yes,of course there are OEMs pins ,threre are on every mxm gpus ,but they do nothing ,because vbios of non-compatibile card do not care about these pins. And this is means "non working OEMs pins = non working notebook mux switch via chipset control" because the PCH and CPU have no idea about of non-compatible gpu card where is in mxm slot. Yes one things is visibility nvidia GFX in uefi bios and second is comunicating with PCH and CPU via these OEM pins.

My plan is use this mini-pc as a excellent testing platform , because there aren´t multiplexers to switching the signal. I can test outputs on (GTX1070 MSI ver., RTX3070 16Gb Peladn, Adlink Quadro RTX 5000 , RTX4090 X-Vsion black pcb ver.) gpus. The eDP-port (Embedded Display Port) are basically DP-port with pwm signal to controlling the lcd brighnees thats all.

Ok, i understant ,but why it wasn´t work. Maybe there is a little differences in right connecting ,or there doesn´t correct term of conditions of running up. Tell me please what is the type of notebook where it eDP works. I will try look to scheme ,and try to find any differences of connecting if there will be. I´m working now on similar project it´s mini-pc with mxm slot ( psychically there isn´t pressent DP-out only SG-option via hdmi out) for better understating the non working DP (a,b,c,d....) output problem ,and then try to add one if it was possible. I can to post more informations about this interesting mini-pc and his modifications i think ,but i didn´t find any section where to add.

Please keep in mind, that mechanic and termal fit maybe it be only a first step to sucefully run 4090 on R2 and then there is a performance issue actually as i said.
-
I found actually some informations about edp output on 4090/4080 . If ianybody interesting about it. Maybe it could be help. MM4090B6-16G.pdf

Or maybye use another gpu manufacturer like ZRT it seems that use a stanard bracket i think. Yes, it´s only one possible option ,but assembling will be much difficult i think. Pay atention about diameter and lenght, less diameterr and longer pipe = less wattage transfer
-
Yes it´s true. It is strong and powerfull with minimum faults like some old car, but already it´s too old. But i am very happy for this piece of hardware.
-
Hi Yes, fits well on the bottom . No stick out issue, but it must use longer bolts and any kind of nuts. x-bracket ver.1.stl
-
Hi Yes, I had this idea a few years ago as well, but I had a problem around the hinges, there are not much of space at this area. Can you explain what your solution is?
-
-
No dimensions is no problem ,yours heatsink will be fit on that gpu . It fitting perfectly in mxm slot ,but there is problem with x-bracket because there are some components like small ceramics condensators in the line for the standard x-bracket. It´s
-
Yeah, that's a right question. Fortunately i made water loop in my R2 because my ADLINK RTX5000 was generating some heat too much. But this gpu have even more high TDP i had to install more powerful water pump and now i have vram temp. a problem too. In one minutes i have over 100C right now, but Hot spot is around 92C and Gpu temp 84C in full throttle and ambient room temperature is 25C.

Hi, i don´t know if eDP will works in M17xR4 sorry. I don't have anything similar to test. There is it. rtx 4090 ori.rar
-
Sorry i don´t test it right now . There is a performance problem like a VRel. gpu voltage issue in 3D applications and other another problems as pcie lines speed as panda_zzz says in a couple months ago when testing 4060.
