As you may or may not know, enabling IGP via FN+F7 does not work when a Clevo 680M is used in the M18x. However, when an unlocked bios is used, you can go into the advanced menu section, then video configuration and force IGP as the primary display (rather than PEG). Once the system reboots, it'll be in IGP mode BUT and I can't stress this enough, DO NOT press FN+F7 to switch back to discrete else your system will go into an endless loop. If that happens, you have to take out the 680M and blind flash the system with a recovery usb. So save yourself the trouble and don't press FN+F7. To re-enable the PEG, just turn it back on as primary in the bios and reboot. I've been playing with the PowerXpress settings but none seem to be able to work with regards to FN+F7, I figured dynamic would do it but apparently not.

UPDATE: The PARTIAL fix is very simple

  1. Download the unlocked A05 M18x-R1 Bios
  2. Boot into the Bios, go to advanced-->video configuration and change the display from PEG to SG (switchable graphics).
  3. Keep PowerXpress as FIXED MUX.
  4. Reboot and now you will be able to use FN+F7 to switch between discrete and IGP.

NOTE: You will again need to set SG in the bios after using FN+F7 one time since it resets back to PEG.

Thanks to @johnksss for the SG tip.

try sg mode instead...see if this will allow you to use the igpu and show the dgpu as well...

you shouldn't have to blind flash the m18x r1. you should be able to reboot it twice with the dgpu removed and then it should come back on. depends on what beeps you hear the first time.

Fantastic, SG mode + Fixed MUXED did it! Thanks for the tip John. Guess that's one more feature we got back with the M18x + Clevo card. If I had a 3D TV I'd test 3D out but don't have one right now. Will test HDMI IN when I get a chance.

I'll begin writing up a guide later today that details how to install a Clevo GTX 680M into an M18x-R1 and what steps to take with respect to installation, inf mods and sg mode setting. It will be published as a tutorial article on the main T|I site.

glad this worked...now waiting on that 4gb sli setup..:).

side note:

im pretty sure if you run sli/crossfire...you will need to switch back to auto mode. and im thinking fn+f7 should still work..... will have to cross that bridge when we come to it.

@johnksss unfortunately I spoke too soon. It worked but only temporarily, once I did FN+F7 back to nVidia discrete, it got stuck in PEG mode and would no longer switch back to the IGP. I had to go back in the bios and manually set SG again for it to work so its only half a solution (better than none at least). Gonna keep playing with the options to see if this can be resolved in the bios.

This is good info. With 7970M CF the Dell cards and switchable graphics works perfectly... same as the 6990M and 580M. (But, yeah, they're still AMD cards and there is no cure for that, LOL.) I wonder if the cards being from Clevo is the only reason graphics switching does not work? Maybe something missing in the vBIOS that the system BIOS is looking for?

If I set my R1 to SG mode I can see both the IGFX and discreet GPUs simultaneously, but Windows will only utilize the IGFX. You can install the discreet GPU drivers and everything, but they stay in 2D mode unless you change back to PEG in the BIOS, and then FN+F7 works normally.

I so seldom use the IGFX that manually setting to SG for the rare occasion that I actually want or need to use it would not be the end of the world.

BIG NEWS

As many of you have been reading, IGP does not work when a clevo card is installed. I can prove that it does with no modding required. Mine works just fine, FN+F7, didn't edit anything or do anything. Now it could be one of two things.

Either the drivers I am using somehow work with FN+F7, or that you need two cards in SLI for it to work out of box. I am not sure which it is, but I am just glad it works lol.

@mobiousblack , interesting, its possible SLI might make a difference. Can you disable one card and then try it? Also, some other questions:

1. What changes did you make to the .inf file?

2. Which driver version?

3. Which bios version?

4. Which vbios?

5. What version of command center?

Thanks and congrats on the SLI.

Thank you Brian. I just used the drivers provided to me by Eurocom. Also according to a user on notebook review a similar situation happened with the 560m's. When using a single card you can't enable IGP but when using SLI it works fine.

As for what you are asking I'll check on those when I am back home and update this post.

1. Any changes made to any INF file would have been done by Eurocom, I just installed the drivers that came with the GPU's from Eurocom.

2. Driver version is 302.92

3. The latest from Alienware

4. Stock, so whatever comes from the factory

5. Latest from Alienware.

You guys are about to get this figured out... awesome. It will make the transition to GTX 680M SLI a lot easier for everyone else.

A little update, I tried disabling one card from device manager. FN+F7 still works for me even with only one card enabled.

I've got SLI in the M18x now as well and it seems IGP works fine with FN+F7 with two cards present in the system. This must be related to a bios switch in the M18x itself rather than drivers.

So does that mean it was because of having a single card that the IGP didn't work? Or was there a bios update that fixed it?

      Hi there guys,
       
      I've been looking into getting a new GPU for my laptop (4-lane PCI-e) and enclosure (HP Omen Enclosure) but I cannot decided between the RX 5700 XT and the RTX 2070 (non SUPER).
       
      I did some price to performance calculations (higher is better) with some of the best prices I can currently get in the UK.
       

       
      The RX 5700 XT does perform better and is cheaper than the RTX 2070 (Although the 2070 does come with 2 games) but my main concern is drivers and from what I've heard NVIDIA cards work a lot better with eGPUs than AMD.
       
      If anyone has experience using both red & green or if anyone else has any other input i'd love to hear your experiences and input.
       
      Thanks.

      Hello everyone,
      some time by now I flashed a custom Vbios (thank you Klem) on an Acer Predator 15 G9-591 and I started doing some tests about how far I could go overclocking the gtx 970m without running too hot. With the voltage up to 1150mV and something like 300 additional MHz for the core clock, in the strongest stress condition for both Gpu and Cpu ( i7-6700hq undervolted), the Gpu reaches a max temp of 85C (with some 86 spikes but never more than that).
      Considering that soon I'm going to relid both Cpu and Gpu and clean everything in the internals (laptop is 4 years old) I think I'm going to have some additional heatroom.
      I've already tested some further overclocking and I noticed that even if the temperatures remains under 93C (which is just for testing purposes, but after relidding temps could be nicer) graphical glitches occur and after some time most games crash. But my question is, could it be because of lack of power supply? The laptop charger provides 180W 
      Could there be an increase in overclock margins with a 230W psu or something like that? (Obviously with the same 19.5V output)
      If anybody tried something like that on any laptop model, or knows the matter, I'd like to know

      Hey guys, I have an Alienware m14x R2, and I have been trying to get access to the BIOS so that I can change the boot options (Everything is locked, I am unsure if someone set a password of if these are locked by default).I've tried updating the BIOS, and resetting the CMOS and nothing has changed this. Would anyone know if there are other options I can explore? Thank you.

      Hey everyone!  After lots of searching it looks like this is the go-to place for laptop mods online, so I figured this would be the best place to ask something like this.
       
      I picked up a Dell E6530 for basically scrap value, and I love the thing.  Runs Xubuntu great, battery is halfway decent, and I can play 99% of the games I own on it.  My friend on the other hand picked up an E6440 with its silver-ish finish along the back.  As much as I love my 6530 I've gotta say, that thing looks great.
       
      To get to the point now, I was wondering if it's possible for me to polish the top of the lid on my 6530 to have a more silver finish like that (or maybe even a mirror finish if I sand it down with a fine enough grit).  Really what I want to know is if the dark grey part of the lid is actually metal.  I can't seem to get a definitive answer online, and I tried the magnet test on it and it wasn't magnetic at all.  This doesn't necessarily mean it's not metal though, as aluminum isn't magnetic but is obviously a sandable/polishable metal.  One source said the laptop has anodized aluminum parts on it, but they didn't specify whether it was something internal or external.
       
      Can anyone here provide me some insight?  If the grey part is definitely a metal and not a plastic, I think I'm gonna give it a try.  As stated before I got this thing for scrap value, so if in the end it doesn't work out I'm not gonna cry over it or anything.  Still though, I'd rather not run into this blind.  If this is indeed possible though and I can accomplish what I want with a decent looking result, I'll post up some pictures with the method I used for others to do as well.
       
      Thanks in advance!

      After spending significant time and effort to obtain "DC" screen for 8770w (which is essentially a regular IPS panel with fancy board that converts 8bpc LVDS to 10bpc DP), I have finally got and installed one. All works great, except of the one problem...

      It has pretty bad banding / posterization in lower shadows. I have tried profiling it in different modes (full range, sRGB, rec709) - issue persists, and it indeed shows only in the lowest part of the characteristic curve. Mids and highlights are represented fine and show low deviation from reference values.

      GPU is HP K4000M, Nvidia drivers installed "as it is", video-card is identified without a hitch.
      Banding was not present with the original TN panel using the same GPU.
       
      While checking a software side, I have noticed that Win10 has bit depth set to 8-bit...
       

       
      My initial reaction was, - "Easy, let's change it in `nvidia-settings` and we're all set":

      ...but that would be too easy, right? After selecting 10bpc and clicking "Apply" screen went off and back on, only to show that depth stayed at 8bpc. Repeating the above few times yielded exactly the same result and I'm not in a hurry to meet a cliched (and laymen) definition of insanity.
       
      Let's check GPU-Z. So far so good, nothing unusual. Notice the highlighted BIOS version and subvendor string:
       
      Time to delve into other tabs. We are running WDDDM v2.4 which supports GPU dithering, but hey... BIOS version has changed!
       
      Briefly back to `nvidia-settings` to check what is reported by vendor's own utility:

       
      So far, we have two strings for BIOS version:
      80.04.5A.00.02 (let's call it an "A") 80.4.33.0.37 (let's call it a "B")  
      Notice how 2nd one seems to not follow hexademical notation. Lastly, "NVIDIA BIOS" drop-down, reports "A" version:
       
      ...and monitor section which confirms that rig is indeed capable of 10bpc, but currently running at mere 8bpc:

       
      Windows "Adapter settings", reports version "B". It's 2019, diversity is a must.

       
      "NVidia inspector" is of the same opinion:

       
      Now, let's use some seriously legit tools and check-in exported BIOS file in `nvflash`:

       
      Here we have two three interesting findings:
      Reported vendor is Dell, not an HP. See this link for details. BIOS version is back to "A". Have I already mentioned diversity? MXM module uses MX25L2005 flash storage in WSON-8 packaging. If things go real nasty, we should be able to rescue a patient via Pomona clip and external programmer.  
      Loading the same file in "Kepler BIOS tweaker" confirms the facts:

       
      EDID settings, courtesy of NVidia Control Panel. Hex dump can be found at the bottom of this post.
      ...Shall I be worried about "60.02Hz" refresh rate?
       
      To summarize:
      Why two different BIOS versions are reported? Anything to do with UEFI (e.g. HP is sideloading its own during boot)?.. Why two different vendors reported? As far as I remember, this is branded HP GPU. Where to get "clean" BIOS of K4000M for future experiments? Ideally from 8770w equipped with "DreamColor" panel from a factory.
