Is it Possible - m14xr1 with external GPU?

Recommended Posts

Hi everyone,

I have gone through a lot of pages of this forum (related to eGPU and overclocking) and they really are very useful but not able to find anything good for my laptop.

My laptop is Alienware M14Xr1 with following configurations :

Intel core i7 2860QM

Nvidia GT555m (3GB)

8GB primary memory 1600Mhz

750GB secondary memory 7200RPM (698.4 GB usable)

900p screen

I want to use a eGPU setup in my system.

Could anyone please tell me whether it is possible or not to use -

In my system there are following ports available - 2xUSB3.0, 1xUSB2.0, 1xHDMI1.4, 1xMiniDisplayPort, 1xVGA, 1xEthernet1000mbps, (I think none of these will be helpful in eGPU setup :tire:)

But i have heard that if you remove your wireless card then you can plug in your eGPU there. Is it true,

Please anyone share your experience with me related to this setup.

Yes! It is possible, I've done it even.

You will need a mPCIe based eGPU adapter. To use it you have to open the bottom cover and unscrew the battery, pull out the wifi card and plug the adapter into there.... then you have the fun of having the cable come out the front of the laptop at the most inconvenient angle on the planet. But! It does work.

Honestly, it's far better to buy a m14xR2 motherboard (and heatsink), put it in the system, put a super awesome custom BIOS/vBIOS by @svl7 then OC the GT 650M. It's about the best performance you can get out of it for the price. It's what I did, you can see a link to it in my signature.

Perhaps a bit late but even with a Egpu you won't get close to the real life performance of a GT650m, tried it with a GTX660 desktop gpu but it ran games a lot slower due to the limited bandwith of the pcie interface.

Benchmarks like 3dmark11 show excellent results but bf3 ran like 40-50 fps at most with 786p.

Well, 660Ti eGPU still blows away the 650M. It's hard to compete with a desktop GPU even if there is a bandwidth restriction.

650M:

NVIDIA GeForce GT 650M video card benchmark result - Intel Core i7-3820QM Processor,Alienware M14xR2

660Ti: (old laptop even)

NVIDIA GeForce GTX 660 Ti video card benchmark result - Intel Core i7-2620M Processor,FUJITSU FJNB231

Even with the performance gap, I'd still suggesting just upgrading the motherboard to the R2 one with the 650M. It's the most cost-effective approach and you still get amazing performance out of it. And you won't have this unattractive mess coming out of your computer lol

As said before (although I've edited the post ;) ) with benchmarkt it looks great but BF3 ran a lot slower on the E-gpu (p4l on a HP probook with a ivy bridge quad core).

And yeah I agree though on replacing the board with a R2 although boards are quite expensive on places like Ebay.

      Hello everyone
      I created a case for egpu using 2.5mm acrylic sheets. The first time I created a case to support a GPU + ATX psu
      Now I created another one for the GPU with an external Xbox 360 203w psu.
      the finish was not good but for my use it is already good.
       
      *both cases album
      *Construction of the second case 
      *adapting xbox psu to 8pin power (taken from 24pin)
       
      all made by hand with the tools I had.

      from Brazil.

      Hello!
       
      I have recently acquired my Dell Inspiron 15 7000, and I am interested in building an egpu setup for it. It has a USB-C port. Any recommendations/guides out there?
       
      thanks.

      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.

      Hi guys, bit of a rookie to the whole EGPU scene. Currently I have:
       
      - MacBook Pro 2015 13inch (3.1GHz Core i7 16GB RAM)
      - Razer X Core 
      - Apple TB3 to TB2 Adapter
      -  TB2 Cable (Cable Matters)
      - 23inch AOC External Monitor
       
      I am wonder about what graphics card to get to run X-Plane11 with high graphic settings?
      I have purgewrangler set up and ready to use with an AMD graphics card, but am also open to the idea of an Nvidia graphics card.
      Any advice appreciated. I did not buy a Windows PC as I need a Mac for various other things and wanted an all-in-one laptop.

      The GPU works, The PSU works, The system works. [individually they all do work]
       
      The system works perfectly fine without the WLAN card.
       
      When i put the system to sleep and hotswap the mPCIe riser and WLAN press something on the keyboard.. Restarts.
      Will shutdown in roughly 27 seconds for those 27 seconds it works just fine like how it normally would on external monitor.
       
      When i shut it down and plug the riser and switch it on, same story. 27 seconds.
       
      I don't even see a error. I get to login screen directly. I used DDU already.
       
      I timed it. no matter what i do if i use the eGPU, External monitor it restarts instead of pause-play. I have 27 seconds.
       
      Need help!
