I'm quite new to this and was super pumped about it when I first learned about eGPUs but kind of heartbroken when I discovered that there were a lot of issues.

I have a Lenovo Ideapad 320s-15lKB

Processor: i7-8550U 1.80GHz

Ram: 8GB

GPU: Intel UHD Graphics 620

 

My laptop does not have a Thunderbolt port, so my original plan was to use the mPCI port and get a USB Wifi dongle.
The GPU I wanted to get was the NVIDIA GeForce GTX 970 4GB.

I have a few questions.

1.- Does using the mPCI cause a bottleneck?

2.-Is it possible to install the eGPU and use the laptop screen?

3.- If wanted, can you unplug said eGPU, and keep using the dedicated graphics card?

Thank you very much guys. Even if no one answers, I appreciate everyone in this website

@joaquin_lobos.

  1. Yes mPCIE have a bandwidth of 4Gbps and more powerful card will run with lower performance. Performance will be limited and depending on the processor will have more bottleneck.
  2. Yes also, but you will lost much of perfomance caused by bandwidth and two way of working method of link.
  3. Yes, you can!

I recently found an old dell inspiron 1545 that I had lying around. I also noticed that it has an expresscard slot. It also has upgradable RAM (I saw one guy manage to get 8GB of RAM in there) and an upgradable CPU. So i'm looking for advice to make this old laptop into a gaming ready machine. Also I did look at the beginner resources and the dell inspiron 1545 seems to be compatible with the expresscard and pcie egpu. So which one is better? Also what would I use to power the egpu, I know a normal desktop power supply works fine but i've also heard that the DELL D220P-01 power supply will work.

@joaquin_lobos,

AS per Mr Ribeiro limited bandwidth may not give you what you need but may still deliver extra performance ti internal graphics. It's difficult to say. If you dont mind making a small investment and feel like you can laern from this or make it a project may be worth it. If its too much risk to spend on the materials or feel you may damage your laptop then maybe not but up to you. It depends on your goals and how much risk youre willing to take.

Here is your laptop's maintenance manual https://download.lenovo.com/consumer/mobiles_pub/ideapad320s-15isk_320s-15ikb_hmm_201704.pdf  pg 37 & 38 show your Wireless Lan port. Looks like an m.2 NGFF connection. THe model used is here https://www.amazon.com/Intel-3165NGW-Wireless-Bluetooth4-0-802-11AC/dp/B0194GE5YC per the parts list on Pg 66

THis port seems like your only option as I couldnt see any other M2 type PCIE connection in your PC

If you want to try it EXP GDC beast is about $50 and sounds like you already have the GPU you already have the card (GTX 970) https://www.ebay.com/itm/EXP-GDC-Beast-Laptop-Independent-Card-Dock-NGFF-Cable-ATX-PSU-Cable-AC866/174245436111?epid=10016018885&hash=item2891d65acf:g:m7kAAOSw33FejvvO

You would have to decide on the power supply.

Your CPU is not too shabby and you might get to play some AAA titles at low or medium. The Mpcie interface is awkward because you have to mod your PC's base cover to allow for it to fit unless you leave the bottom cover off. Taking it out to use your laptop is inconvenient especially if you have to use your laptop. I have seen some people make a small cut in the bottom cover and then tape the connector from their PC to the beast to the bottom of the PC. You could always unplug it at the beast if you want to take your PC with you but may need to tape the cable to your PC See what the build below did. https://egpu.io/forums/builds/2013-samsung-np550pc-s04tr-i7-3630qm-exp-gdc-8-5c-mpcie-msi-rx-470-4gb-msi-rx-5500-xt-8gb/  

what do you mean by this question? "If wanted, can you unplug said eGPU, and keep using the dedicated graphics card?" do you mean unplug the EGpu and continue using the integrated graphics of your PC? Yes it happens automatically

If you feel it's worth it then it's your choice. EXP GDC beast with MPCIe connections usually have a few challenges from what I've seen so will need to research on this site and you can make it a project. I have only ever done express card with GDC EXP beast so I have no first hand experience.

If you use the laptop screen it will impact your performance even more as you are sending traffic back to your PC through that limited bandwidth. I highly recommend an external monitor to get better performance. that way your PC sends data to the EGPU and the GPU sends data to the external monitor to be displayed and doesn't send all that back to your PC and collide with the data travelling from your PC to the card at the same time. It can mean as much as 40% better performance to use an external monitor.

Hope this helps. Im not telling you to do it or not just trying to give you as much data as possible.

@mobas07, I did something similar with  Dell Latitude 6430 and used the DEll Power supply. It worked great for me

https://egpu.io/forums/builds/14-dell-latitude-e6430-rx5804gbps-ec2-expgdc-beast-8-4-with-expresscard-win10pro-sabrefv/

I did need a couple of extra connectors which didnt come with the EXP GDC but I didnt want to go through all the hassle of shorting pins on the power supply. I had an rx580 which was 8 pin so you need to think about your card and get the right connector to go from the beast into your card

2. PCI-E 6-pin to 2x 6+2-pin (6-pin/8-pin) Power Splitter Cable PCIE PCI Express – $3.49 (I couldn’t find Beast 6 pin male to 2 x 6+2 pin male and didn’t want to wait for it from China. Only female to male available on ebay) – this provides power from the Beast to GPU. Looks like this

3. 60cm 18AWG 6Pin Male to 6Pin Male Video Graphics Card PCI-E Power Adapter Cable - $6.33 (works with the previous item to make it male to male like the Beast cable) something like this

4. Used  Dell DA-2  USFF Power supply Optiplex 745 755 760 D220P-01 MK394 AC ADAPTER - $10.45

I know a normal desktop power supply works fine but i've also heard that the DELL D220P-01 power supply will work.

Yes, a EXP GDC has a 8-pin input power socket specifically for a Dell DA-2. It's also supplied with a 6P+6P PCIe power connector. That means you use a video card with a 6P+6P (225W) or 8P (225W) PCIe power connector.  Do GPU undervolting if hit peak limit instability OR use a second Dell DA-2 with splitters to drive the PCIe power sockets as explained below with example build:

@cpt_force, I think the NGff port you are referring to is for a SATA SSD and not a PCIe slot?

your service manual http://h10032.www1.hp.com/ctg/Manual/c04825510 on page 21 shows the 128GB and 256GB m.2 SSD drives that can fit (826393-001 & 826392-001) which if you Google them are both SATA SSDs and I think SATA is for storage media only and not for PCIE. When I googled this on the internet I found this in a blog comment "You can't convert SATA to PCI-E. Primarily because SATA ports have a controller that is on the PCI-E bus, and can't bypass it. If there is a wireless network card in the laptop you can use that PCI-E mini slot, but there is absolutely no way to use a SATA port."

Your Wifi card is a mini PCIE port and maybe uses an NGFF type connector. If you look under (20) WLan on page 21 they supply many different types of cards depending on location. YOur device manager should tell you which you have.

@sabrefv, Do You think I would be able to use an RX 580 with my build. Also roughly how much performance would you lose with expresscard vs mini pcie vs native? (Thanks for the helpful links in your and @nando4 's previous posts)
