    Hello, I recently installed the zotac GTX 1070 (these MXM GPUs out of their zBoxes) in my M18x R2 and so far everthing works fine(besides the strange fan behaviour, but thats another topic). As the lack of LVDS support I have to use the GPU in SG mode, so it's running over the iGPU. When connecting an external monitor I noticed that its also connected just to the iGPU which is bad for me as I want to use a high refreshrate screen. I digged through the schematics of the laptop(easily avialable) and noticed that the video outputs are switched by MUX switches that are controlled by the EC. My question now is: is there any way to switch these chips by software like a bios setting or something else? Otherwise I would just set them manually as these chips just get an high or low signal to change the input.

    I had the same problem. You need to reflash the bios chip with a dump from another machine. After that you have to use the backflash method to get it working again

    Got a little update, it’s working again! it was actually the bios which was the culprit. I removed the SPI Rom chip and flashed a dump from another machine(thanks to the guy from Reddit who send me the dump). After that the backflash was working again(and necessary) and I downgraded back to A03. After lot’s of beeps I finally got a picture and it’s working fine now 😄

    Yes, it’s actually almost the same issue. The only difference is that I had no problems before at all. I changed these setting to get some performance increase as I’m running this thing in SG mode(GTX1070). I’ve done the CMOS reset in 3 different ways: 1. I unplugged the battery and waited some time. 2. I unplugged the battery and shorted the battery pins on the board. 3. I left the battery in place and shorted the clrcmos and reset ME pins on the board. These pins are hidden under the msata cable. These can also be found in the schematic which is easily available in the internet. At this moment I rather think it’s the Intel Management Engine firmware which is corrupted. I believe that as this piece of software is absolutely necessary as this initializes CPU. That’s also why it’s not possible to completely disable this junk. For me this would also explain why the reflash method does not work like in the past. The bad thing about that is that this firmware sits on its own rom on the board, so just taking the bios file and using an external programmer seems impossible without having a dump from that exact rom

    Hello guys I've got a pretty weird problem with my M18x R2. I already searched the web but couldn't find an answer. A few days ago I changed some settings in the bios, if I remember correctly DMVT Pre-Allocated. After saving this setting the notebook refuses to even POST. I get no beep errors or anything. If I press the power button the system turns on, the LEDs turn on and then the system shuts itself off. I already reset the CMOS, the IME, tested different hardware configurations and so on. If I remove all the memory sticks I actually get the memory error code. At this point I'm pretty sure that the bios got corrupted for some reason when I saved these settings. Did anyone had a similar problem and got a solution for this? I repaired lots of notebooks but never had an error like this... EDIT: The Bios installed is the a15 unlocked which worked fine until recently. Overall there were no problems at all indicating different kind of problems. I also tried the backflash method with the A03 Bios but the system refuses to read the USB stick. I've used the same stick as last time I reflashed the Bios.

    Thanks for the info! Have you just add the additional MOSFETs or did you replace all with matched ones?

    Hello guys, I have some questions regarding the GeForce GTX 980M. I'm using this card for 2 almost two years now and it's still impressive how much power this card has, especially if you think about the age. I was first using this card in my M17x R4 until I got a M18x R2 for an outstandingly cheap price. I upgraded the M18x with the 980m from the M17x and everything worked fine. As the cooling is better than the 17 I flashed an unlocked vBios(svl7's bios) to get the full potential out of this card. This was working fine for the last two weeks until yesterday. I played GTA V for two hours. Temperature was fine and the card pulled around 110-120w. Then suddenly the screen went black and the overcurrent protection of the PSU(330W Dell/Delta) took place. After a few minutes of measuring I found the GPU, specifically one of the MOSFETs to be the culprit. I replaced the MOSFET with one I found on a K2100M I had lying around(it's the same part, CSD87350D). The card works perfectly fine again and beside the MOSFET luckily noting else was damaged. Long story short: How much can the power stage withstand with three MOSFETs and does it make sense to add the other three "missing" ones? And how much current can the MXM port of the M18x R2 deliver without being damaged?

    That was what I thought too, but on the other hand the 7970M seems to work fine without modifing the systems bios(works by using a vbios with enduro disabled). I may gonna try diffrent vbios versions. Found one that seems to be compatible with the clevo d9000f which, I guess, shares software parts of the bios as it's from the same era.

    Hello, I have an old Clevo W870CU lying around here for some time now which I got pretty cheap due to a faulty CPU vcore capacitor. I now got my hands on an Alienware M18X r2 with two GTX680M's that I wanna reuse as I upgraded this old boy to a single 980M. I installed the GPU and got the BIOS splash screen and the notebook even booted into Windows. After several seconds I noticed that the indicator lights started to blink while the GPU fan was ramping up to full speed. A few seconds later the notebook shut itself down without warning. I then went into the BIOS and saw that the GPU was recognized as "GPU UNKNOWN". Now my assumption is that the vBios is incompatible and that I need to flash another one(like how it is with MXM in general). Has anyone ever done this upgrade on that notebook and has some experience to share how to get this thing working? GPU Is the Dell GTX680M 2GB

    Nice mod! How does it sound compared to the original, working speakers?

    I've done that with my 3840QM too. Hits around 90c under full load but is relatively stable and nearly always at 4GHz all core. If the CPU throttles, try to increase the long and short duration power limit. This might help, but i'm not sure about the longevity in terms of thermal stress for CPU and mainboard
