Hi,

I have succesfully managed to make an Asus X550JX working with eGPU, and I would like to share it

 

 

LAPTOP - 2015 Asus X550JX

  • CPU: i7-4720HQ (4C, 8T; 2.6GHz base clock up to 3.6GHz)
  • RAM: 12Gb DDR3L 1600MHz (4Gb soldered + 8Gb stick)
  • dGPU: Nvidia GTX 950M 4Gb GDDR3
  • Screen: 15.6" 1366x768
  • Storage: 4500RPM 1TB Toshiba HDD + Kingston A400 128Gb SSD (in the place of the ODD with an adapter)
  • OS: Windows 10 1909

eGPU hardware

  • PCE164P-N03, mPCIe
  • PSU: CoolerMaster MasterWatt Lite 600 (600W 80+)
  • External Asus VP249HE IPS 1080p monitor
  • Sapphire Radeon RX580 OC 4Gb

Building

  • this laptop has the mPCIe slot in a strange location, it is facing upwards, it is just beneath the keyboard, and under it goes the heatpipe, so this is what I did with an mPCIe extender like that

  • to make the laptop mobile, I used that opportunity, so if I want to, I can swap the wifi+bluetooth card to the eGPU adapter
  • to be able to do so, I found an another way for the antennas:

  • at the end I have the mPCIe extender coming out from the computer between the case and the battery:

Putting it all together

  • I didn't want to disable the GTX 950M, because it performs okay on the internal screen
  • I turned on the laptop with the wireless card in it
  • put it to sleep mode, and swapped the wireless card to the eGPU adapter
  • in device manager there was my RX580 as Microsoft Basic display adapter (I haven't hooked the monitor on the RX580 yet)
  • I downloaded the Radeon Software and installed it
  • I restarted the computer, but now I hooked the screen on the RX580
  • and in task manager I could see all the 3 GPUs (iGPU, dGPU and eGPU) and the external screen was working fine from the eGPU

  • after playing around, I found that the best settings are: downclock GPU core by 25%, overclock memory to 1900MHz, and overvolt by 15%

GAMING

In 1080p it improved much (with external screen). With the same quality settings I can easily hit over 60 fps in my games, my avg fps improved much, but the drops are bigger and more noticable! I haven't benchmarked the system, I can feel the huge difference, but if you would like to, I can compare the dGPU and the eGPU in 1080p.

I play GTA V, ETS2, ATS, Dirt 4, Transport Fever, Rainbow 6 Siege, Project Cars 2, Mad Max, and sometimes WoT. I could even turn the settings up while keeping the high fps. But I needed to disable Vertical Sync. If it is enabled, then the eGPU will stop working after around 10-15 mins, and I need to restart the game, which is quite annoying especially with GTA V Online, where the loading times are pretty high. If you have any questions, don't hesitate, ask in the comments!

 

Thanks for checking my build!

 

UPDATE: after disabling the dGPU (GTX 950M) in device manager, the eGPU's performance and stability increased a lot (maybe this has to do something with the PCIe lanes, but I don't really know)

My setup:
ASUS X550JX (i7-4720HQ, 12Gb 1600Mhz DDR3L, 1TB HDD + 240Gb SSD, GTX 950M 4Gb GDDR3)
ASUS VP249HE FHD monitor
Sapphire Radeon RX580 4Gb OC

Hey, thank you for trying this out.
There's a problem, I can't access the photos you linked, could you relink them to imgur or something else? I'm really curious how you managed to get the mpcie cable out.

 

I have the exact same laptop and I wasn't sure If it'd work but I guess it's worth a try now. Just asking, is this the exact model? ASUS F550JX-DM247D

@lung_bogdan, yeah, sure! Now I can see, that there's only links there, but when I uploaded it, they were here. I will upload them soon 

And as far as I can see, they are identical, they share the same chasis etc, except, that yours came with SSD out of the box. I'll check out a disassembly video, and some ebay motherboard listings to see if they are the same

I checked it out and I'm 99% sure that they are the same except the letter in their name. I hope you will succed, but ask me, and I'll try to do my best 😉

I'm currently waiting for the mpcie to pcie x16 adaptor. It should arrive this week. 

After my research, you have the X550JX version of the laptop which is 1366x768 and I have the F550JX (1920x1080), the only difference between mine and yours is strictly the screen. Unfortunately I didn't find any mpcie ribbon cable extenders in my country, as you did so I'll try my best to route the cable without bulging my keyboard too much. I plan on playing on my internal screen, even though I heard only bad performance by doing that. 

Did you try playing on internal screen at all? I'm really curious about that.

 

I'll be using a GTX 1060 3GB version with a 520W power supply and the exact same adapter as yours, the PCE164P-NO3. If you encounter any issues let me know what I could bump into Grin

 

P.S It's so sad just looking at the gpu and power supply and having to wait for the adapters 🙁

I have linked an extender ribbon cable in my description (if you click on the blue "that" right before the frist picture) from AliExpress (I also ordered it from AliExpress).

And yeah, I tried it, and you will better get an external screen, because the eGPU on the internal screen is worse than your dGPU, even on my smaller resolution panel.

And so far I haven't had any issues. Just make sure that you turn on your PSU then your laptop.

huh, seems I'm not so lucky...

Same X550JX specs only with just 2 GB DDR3 of GTX950Ms Vram and 240GB SSD

my PC isn't able to detect my RX580 4gb

funny thing is this: if i turn my PC into sleep mode, the RX580 goes off too...

any idea what to do?

@hoholu, I've ran into the same issue. What I did was (I have found it in this page, in the intallation guide): started up my computer with the wifi card in it. When it booted up, I closed the lid (put it into sleep mode), then swapped the wifi card with the eGPUs' mPCIe connector. Next, I gave power for the RX580, and when I was sure that it had power (I have the sapphire RX580, and when it has power it has a lighting Sapphire text on it), I opened the laptop, and went to Device manager. Here I could see, that there was a Generic Display adapter. So I went ahead and installed the drivers (finally I only installed the Radeon Software, because Windows Update already installed the drivers, and in Device manager the card showed up normally). So I rebooted the laptop, and it was ready to use.

Hope it helps, I have no other idea (but tbh, it should work for you as well)

Good luck, and let me know if I can help.

@botond_boldizsar, yay! it works...kinda

instead of plugging powered RX580 to sleeping X550JX...

Firstly I get my PC to sleep, than unplugged wifi, than plug RX580 (NOT powered), than I started PSU and after that i woke PC from sleep, i installed drivers... BUT I'm not able to switch to run app on eGpu...(I'd like to use internal screen)

right-clicking the app>choose graphic processor> I'm stuck with choice of iGpu or dGpu...

what to do?

@hoholu, Just disable the dGPU in Device manager, and you'll notice, that the high performance GPU will be the RX580.

PS: just sharing my experience... You'll have less FPS on your internal ~720p screen with the RX580, than you would get usually with the dGPU (GTX 950m). I'm talking about that my max FPS with the eGPU on the internal screen was 30, at the better times, averaging around 25, and with horrible framerate drops. If you can, hook up a TV or an external monitor to the RX580 😉

Sapphire Radeon RX580 4Gb OC

Hi I have a very similar model (Asus X550VX) with the following features:

CPU: Intel Core i7-6700HQ

GPU: Nvidia GTX950M 2Gb

RAM: 16Gb DDR4 2400MHz

What caught my attention is that the motherboard is practically the same form factor as your model. My question is: if I can hook up a GTX1660ti or what graphics card would you recommend?. Did you had to change any BIOS settings?

With the stock setup it runs ok. I can play Battlefield 4 at medium settings and BFV at low settings and many other less demanding games. But when I try to play CoD MW Warzone, well... is not so great. I mean the game is totally playable,but lets just say that I'm not getting the greatest experience, basically I have to turn down the resolution to the minimum(720p), set the graphics to very low settings and get an average of 40 to 57 FPS on classic multiplayer and 30 to 45 FPS on Warzone since it's a huge maps with tons of players. 

So anyways I'd really like to try this ePGU thing mainly due to budget reasons and because I'm really happy with this model, it is a pretty decent laptop with an entry level discrete graphics card and the processor does a pretty good job.

 

Thanks in advance I'm glad that it worked out for you.
