    I don’t bother doing it when I’m just going to do regular PC stuff but I do it whenever I’m going to start a game. It really only takes a minute while it will take you much longer to run a game or benchmark to check.
    I still have my third fan plugged in but since there’s no secondary GPU and heatsink it’s pretty useless.

    Hey guys, I don't want to open a separate thread for my problem since it might be similar. I also have a GTX 1070 (black PCB MXM 3.0b standard layout), but it won't show up abymore. It happened when I wanted to "remove" the power throttling (classic SG -> igfx, boot to windows, reboot, igfx -> SG procedure) we all know and love. Then my CPU started to act up stying in random multipliers (×21 to x29 instead of OC multipliers), but my GTX 1070 was still present. After a normal reboot the 1070 wasn't detected and CPU still acted up. I ran a ePSA test (which checked out completly fine, even video card connection test and video memory test, but I'm not sure if it really meant the mxm card) and checked the BIOS for weird settings. Everything was normal. Booted back to windows, CPU was still acting weird, no 1070.
    I removed the CMOS, let the PC sit there without it overnight. At least that has helped with the weird CPU behaviour, running at normal speeds (Level 1 OC on 3920xm), but no 1070. Checked in BIOS, no PCI card detected, set in SG. ePSA still reporting no problems... help please?
    Thanks in advance

    Edit: I don't have acces to another mxm machine nor GPU since I'm stuck in Cuba thanks to corona.

    Edit 2: There was no Bluescreen or any other visible nor olfatory indication of a GPU failure.

    Welp, forget that, seems like I didn't notice the windows update 1909 and the mess it can create... At least everything is back to normal... for now...

    It looks like he went back to an earlier Windows version and the card came back.

    Oke so was just windows. Anyways I saw an used MSI from Germany (Ian from Italy) an new black pcb it’s selling just from China and import taxes are crazy so it’s not an option, he sell it as 100% working maybe it’s the good one?

    Hiya. I wanna do an upgrade also on my m18x r2. Current 3610qm and 780m sli
    But im in a hard decision whether to go for the 980m sli or the single 1070m.
    Im pretty sure most people have had these cards and the experiences with them. Ive spent months reading and trying to find comparisons between the 2 set ups but there isnt much info especially in the form of videos.

    I really want to go with the 980 sli route. I know some of you will say sli is dead etc and can come with its problems. Eg. Throttling and sli compatible issues with games but ive also read some people have 980m sli with no throttle issues by doing the igfx to peg reboot trick. Plus there are profiles for games which can help.

    Now with the 1070m i know having one installed will be less power hungry and less headache compaired to 980m sli set up.

    Now my question is with my current 780m sli, in some games not all and programs such as 3d mark and valley engine i cant use them because i get this major flickering strobe lighting effect where sli dosnt seem to work properly. There is a way i can sort this out and thats by going into display settings and duplicating the cards to use 1 single display which i read ages ago on some other forums. Does anyone know why is happens? Or is it vbios problems on 1 of the cards?
    Another problem with this is that this trick only works in windows 7 and there isnt a way to do the same thing in windows 10 :(

    So has anyone experienced this issue with 980m sli setup out of the box or is it just my 780m set up? I have both OS installed just so i can play some of me sli games in windows 7.

    Now with the 1070m. Ive read up on how to get it installed and working.
    Its the comparison in its power compared to the 980m sli. Ive read comparisons where benchmarks n scores of 1 x 1070m beats the 980m sli but then ive also seen some where they say the 980m sli beats the 1070 in good sli scaling games. Its so confusing hell.

    Please give me your experienced advice. Im not much a major gamer as i used to so im not so bothered to play games in ultra high or 4k and i just only wanna future proof my beloved m18xr2 a bit more so i can play games like red dead 2 at reasonable fps where it curently only runs at like 14-20 fps on ultra low!!

    Hi. I’m not really sure about your current 780M issue, all I can think of is that maybe one of the cards is starting to fail or it’s overheating.

    My vote would be for the 1070 upgrade. Yes, benchmarks will show the SLI 980M’s to be comparable to a 1070 but it will be different in real world gaming due to the lack of SLI support as you pointed out.
    You will also find that two 980M’s will generally cost more than a single 1070 so you’ll be paying more for less performance. You will also have driver support for longer as they will drop 980M support over the next few years like they did with the 700 and 800 series.

    Its not my cards as ive also read on other forums that people have also experienced the same problems which is how i found out about the duplicating screen trick to fix the sli. Some sli games worked fine without this trick such as rise of the tomb raider and then theres others that don't.

    Money isnt really an issue in regards to 980m sli as these cards are pretty cheap now and can buy them off aliexpress for as cheap as £160 per card.
    I just wanna hear peoples experiences on the comparisons. I know im kinda late on the game and people have probably moved on to better systems. Where as for me i wont be changing laptops as this m18xr2 is such a beautiful machine. I am tempted on the 1070m though

    Sli doesn’t make sense at all nowadays, dx11 is dying, more and more games are in dx12 and it doesn’t support sli, just explicit mgpu that developers must to set on to be working and its not happening because mgpu is dead so don’t waste money on two gpus just put an 1070 or quadro rtx 3000 or wait to see if someone will produce some mxm rtx. Plus gtx 980m are very crap ones they have always problem like to be defective
