1x PCIE slot is fast enough for folding.
I've done so on a GTX 1060, and got 200+k PPD, vs 320kPPD on the 16x slot.
I'm sure a 1070 or 1080, or RTX card can work as well, but only for Linux.
Windows uses more data, and people have said to lose performance over 1x.

1x PCIE slot is not recommended for gaming, but will work fine for bitcoin mining or folding.

for the ssd take a 6gbs (x2) and connect in m.2 E with this https://www.ebay.fr/itm/Riser-prolongat ... 0005.m1851
And for the gpu (with external psu) https://egpu.io/external-gpu-buyers-gui ... -interface

Anyone tried out the first link (M2 E-key to M2 M-key adapter) with a NVMe M2 SSD? This would free the M2 M-key slot for a eGPU.... I don't think there should be much loss using PCI x1 with a SSD..? Much more to be gained using the eGPU in the M-key slot, IMHO? But does the above adapter actually work, to be able to free up the M-key slot!?

(PD I have a WD Black NVMe SSD, already installed in my MacPanda, and a GTX 1070 8Gb spare - right now with my 12-year old 720p TV, I am getting round 20 FPS with Subnautica, just playable, but I will be soon obtaining a 4K TV, so I would expect FPS to plummet...)

Thanks for any comments!

Andy,

In theory yes.
About a year ago, I wasn't even aware that NVMe SSD can/may/"that depends" work in a non-x4 configuration, until I tried a specific brand/model
2x NVMe (yes, it was using a controller+firmware designed only for 2x operations) on a key-B slot (had to cut that key-B slot, a different story altogether) can indeed
work in a PCIe 4x slot.

So the real question is: your specific brand/model of the NVMe SSD would work in x1 mode?
This is never seen in any published spec. anywhere so YMMV.

Hi ccs-hello,
I haven't yet managed to find another place for this https://www.ebay.fr/itm/Riser-prolongat ... 2638347252?, except for some suggestions on the same page, but I'm not willing to cut up my new M-key NVMe when an adapter that possible works is available - was hoping to hear from some LPA devs here on whether they think it should work and possible losses, taking in to account the advantages of now being able to use the M-key for the eGPU...
if the theory is yes, then I will probable spend those 25€ to try it out... I don't see why the NVMe SSD shouldn't work in x1 mode, as far as I understand these PCI buses just throttle back available bandwidth when using less channels, but... maybe get the adapter first and wait to see before also getting the M-key eGPU adapter

the alternative is keep the SSD in the M-key, and get an adapter to put eGPU in E-key https://www.amazon.com/NGFF-Express-Ris ... ay&sr=8-18, or https://www.amazon.com/Sintech-PCI-Expr ... ay&sr=8-48, but then will be restricting eGPU to max PCI x1, which is kind of worst case with GTX 1070 that I have spare

Thanks!
Andy

First link: also check regular ebay site item 223030383891

(No need to cut a slot on NVMe SSD.)

Thanks for that article number, found it in my local ebay store
Will take a while to get here, but will post the results of the installation, together with the revised Xbench disk access speeds, to be able to compare - and if all works well I'll be getting the M-key eGPU adapter and be making a 3D printed case for the eGPU as well, so will also share that on Thingiverse

Cheers!
Andy

I tried out that adapter and posted some info here:
https://www.lattepanda.com/topic-f6t17046.html

I also posted a video of it initially working here:
https://youtu.be/UUT99pgk_Bs
and will post another video with benchmarks and boot times for windows 10 in the next day or so.

Here is my review of the adapter including benchmarks and boot times

Hi guys,

I would like to use both SSD with NVMe (M.2-2280) and a graphics card like Geforce GTX 1050Ti.
Is it possible?
Please help me find a adapter/or how to setup that fit with this requirement.

Thanks.

Here's my video that covers a LattePanda Alpha with GPU and NVMe SSD, all powered off one power supply
