    What do you guys think about this for the Alienware 18?



    It’s basicly using the PCI-E slot to run the gpu. Looks workable and quite a cheap alternative

    The issue is it would only be running at X1 speeds, which is very slow compared to the x16 its used to. people have been trying to create MXM 3.0 to PCIE x16, but im not sure whats happening there, but that would give full x16 speeds.

    And in the alienware 18 you can get current gen video cards, so its abit pointless, but in cheaper laptops without graphics cards there would be atleast some usefulness to it.

    Ive currently got a gtx 1060 in my alienware 18, but you could order a cheaper older card, and get better performance that you probably would from even a 1080ti in one of those, because of the x1 limitation

    Its called Sour Ninja Dual Wield IIRC, but it never made it to market ( it did have a kickstarter) and I believe there is a guide to making your own version of it floating somewhere in the web

    I have no clue on earth why you would ever want a x1 eGPU, the bandwith slows everything down to around 1050 speeds at max, and you could just buy a 980M at that point

    Yeah the sour ninja died in kickstarter, and the guy basically went awol. and there was a DIY one, but last i heard they were using bad cabling and needed improvements and went quiet

    and if you had say a i5 notebook with no mxm at all, and you hooked up an egpu with even like a 680 youd probably see improvements over integrated graphics

    A shame, but possible with good soldering skills

    Well of course it would yield improvement, but OP is asking specifically about the AW 18

    yep, and in my original reply I stated that it would be pointless :)

    I’m not sure what you mean by a x16 but my neanderthal brain can realise that it would be better than x1.

    I guess this idea is off the table then and I may as well get a 1060 mxm to replace my 780s .

    Does anyone have a link to the modified heatsync that’s needed for the aw18 r3 please?

    think of it like a highway but for your data, now pretend x1 is just a standard two lane highway. one up, one down.
    now compare that to the amount of cars that would go through on a 16 lane highway :)

    and I got mine off of @woodzstack , he modified my heatsink, and sold me my 1060 at a great price :)

    i can try finding a link the the mod you need to do on a 100w heatsink though if you want

    also - Door-Hinge rhymes with orange

    IMO 980M is better, as its usually cheaper, doesn't require modification for the heatsink, and can be SLI'd

    Funny that this thread should come up today.

    I've always wanted to try the ghetto eGPU Mini PCIE idea. I already have a Dell PSU that I can use to power the Beast GPU dock, so I just needed the dock itself and a GPU. I Ordered the dock and a used GTX 750TI today.

    I occasionally play games and so far my current iGPU systems have actually been OK for older titles. I recently got into Hitman Absolution, where the iPGU's have showed their inadequacy to the point that they are intolerable. In addition, there a few other uses where an eGPU might be useful and I've always just put up with painfully long wait times rather than buy a system with a solid discrete on-board GPU. I know that there'll be a big performance hit due to the Mini PCIE connection but I'm curious to see whether it's worth the improvement over the iGPU.

    In all likelihood the setup will be terrible but I will at least have done something that I've always wanted to try. I can then just build the super-budget desktop that I've been considering building and use the 750TI there. On the other hand, I don't really want yet another computer lying around, so the iGPU could be a viable improvement in the event that the performance is OK . The super-easy access to the MPCIE slots on my systems make this a genuinely viable option. In addition, the Dell PSU means there's just a discrete power brick and not a huge ATX PSU powering the dock - something that has always annoyed me about homebrew eGPU systems.

    None of the systems that I'll be trying the eGPU on will be amazing quality however I'm more than happy to post up some results if you'd like. At least then you can see how much improvement you gained by upgrading the internal GPU for your system - rather than a janky MPCIE eGPU solution that effectively kneecaps your GPU's performance.
