eGPU with the GTX 1070/1080. Is it possible/worth it?

Recommended Posts

Hello, 

I own a Lenovo Y510p with a GT755M SLI configuration (which almost always overheats/crashes for games that DO support them) and i plan to set up an eGPU for it.

I've done a considerable amount of research on the topic but there are still doubts to ascertain before moving on.

 

1) Is it possible for the latest series of GPUs (GTX 1070, GTX 1080) from Nvidia to be used as an eGPU? Those who've already tried it used stuff like the Razer Core or it's other branded equivalent. What I'm looking for is the complete DIY version using the EXP GDC V8 connected to the mPCIE underneath the laptop (the one which the wifi card uses). I am aware of the Thunderbolt tests on Macs but I'm curious about it's performance on the mPCIE. And would it be compatible with the mPCIE adapter? Would it be too "new" for my laptop bought in 2014? 

 

2) If it is possible, would it be worth it? Would the bottle-necking of the mPCIE be enough to diminish its worth? I wouldn't want to go for the GTX 970 or GTX 980 because my long term plan would be to use the GTX 1070 on a desktop set up once I settle down. (I'm a travelling student btw)

 

Thanks in advance.

The EXP GDC product page has a good chart outlining what cards are ideal for PCIe x1 gen 2: http://www.banggood.com/EXP-GDC-Laptop-External-PCI-E-Graphics-Card-p-934367.html

 

I don't know if there's much truth to it, since I presume different applications might utilise the PCIe bus differently.

 

It should theoretically be possible to benchmark every card at PCIe x1 speeds to determine at what point additional graphics horsepower becomes meaningless due to PCIe x1 bottlenecks.

      Hey Everyone. I'm looking through the forums and found out that I can make my old Lenovo a Hackintosh. Is it worth doing? Can you dual boot Windows 10 and OS10?

      I added this post in the another forum a few months ago but felt like it could also help someone here, enjoy... So ive owned quite a few Alienware laptops but out of all of them my favorite has always been the great m17x R4. I love its aggressive looks, its lines and grills remind me of lamborgini design, the 1 glass sheet screen, the media keys looked futuristic and its laser etched name plate added a touch of personalization and attention to detail that they used to have. So considering it still has powerful specs for modern standards, i7 processors, 32gb ram, 2ssd and 1msata slots, 120hz 3D display, mxm slot, sd card reader, I couldn't help but to sell my 2 current laptops (15 R1 980m, 4k, 15 R3 1060) and purchase a pristine example of this machine with all its original packaging to upgrade it up to todays specs.   The Original Specs of this particular system were:  * Intel i7 3820qm 2.7ghz / 3.7ghz  * Nvidia GTX680m 2gb  * 8gb DDR3 RAM 1600mhz CL11  * 250gb Samsung 840pro SSD  * 1tb Seagate Momentum HDD  * 17" 1080p 120hz 3D display Desired Upgrades:  * Intel i7 3940mx 3.0ghz / 3.9ghz  * Nvidia GTX 1070 8gb  * 32gb DDR3 Ram 1600 CL10 Corsair  * 1tb Samsung 860 EVO SSD  * Liquid Metal and better thermal pads    2019 Specs: * Intel i7 3940mx 3.0ghz / 3.9ghz  * Zotac GTX 1070mxm 8gb  * 32gb DDR3 Ram 1866 CL9 Corsair Vengeance  * 1tb Samsung 860 Evo SSD  * 256gb Samsung 840 Pro SSD  * Liquid Metal and Fujipoly 17w/mk thermal pads  * 17.3" 1080p 120hz 3D display   I already purchased the GTX 1070 mxm, 32gb RAM and the 1tb SSD. The GTX1070 is installed and working at its full power. I applied Thermal Grizzly Conductonaut liquid metal thermal compound to both CPU and GPU and Fujipoly ultra extreme 17.0 W/mK thermal pads with my modified GPU heatsink and new X-bracket. CPU is overclocked from OEM BIOS to stage1    4.1ghz  3.9ghz 4cores. No chasis or board was cut or damaged during this process as I wanted to keep its integrity and no throttle issues what so ever. As I already had the 120hz edp screen, it was an easier job to do and thanks to @Striker123 and to @D4ddy for their threads as they made me have the guts to go through the project and to Rick for selling me this perfect example of a computer.   Alienware m17x r4 1070 mxm http://forum.notebookreview.com/threads/msi-gtx-1070-mxm-successfully-working-on-alienware-m17x-r4-another-socket-victory-against-bga-crap.803637/ Alienware m17 Ranger 1070 mxm http://forum.notebookreview.com/threads/alienware-17-r5-gtx-1070-mxm-3-1b.800137/   Here are some before and after benchmarks so you can see this baby flying let me know what you think about these numbers... I will be uploading more pictures soon as it only lets me upload 5. If you guys have any questions id be glad to help out.   current issues:    - the GPU fan does not automatically work so I have to use HWinfo to manually build the fan table but HWinfo sucks balls at this and doesn't start them automatically either, also with HWinfo I take control of both CPU and GPU fans at the same time and sometimes I just want my CPU fan to be spinning. so if someone has a fix for this man that would be great!

      Hi, I'm having problems trying to connect a GTX 750 Ti to my Lenovo T420 using the dock EXP GDC Beast (express card version).
      My laptop: Lenovo T420
      RAM: 8GB DDR3
      CPU: Intel Core i5 2520M
      GPU: Intel HD Graphics 3000
       
      My problem is: if I plug the express card and I turn on the laptop it doesn't boot up and the screen becomes horrible, with coloured pixels and a sound like "bip-bip".
      If I try plugging the express card when the laptop is already turned on it sees the gpu, but if try installing the drivers I have to apply the modifies restarting the computer.
      I hope you understood my problem (I don't speak English very well).
      Please help me, It's making me crazy!
       
      EDIT: I didn't say that if I plug the express card when the pc is already turned on, in the device menager there is "Error 12" on the gtx 750 ti

      In this thread you can post your requests for Lenovo Y50-70, Lenovo Y70-70, Lenovo Z50-70, Lenovo Z70-70, Lenovo G50-70, Lenovo G70-70.
      If someone wants upgrade Wi-Fi card and remove whitelist, or unlock hidden additional menus and settings in bios setup menu, or unlocked vbios for overclock NVIDIA card, then you can post your request in this thread. Also, if you have a problem with fan pulsating/clicking on any modified bios then you can post your request in this thread.
       
      The flashing procedure include two steps:
      1.  Flash main system bios.
      2.  Flash EC firmware.
