Give me confidence or shoot me down
I've went through all the basic content of this site and I think I'm ready to take the risk and try a purchase.
Before I do though, I thought it might be a good idea to announce my plan to you experts to see it anybody shakes their head in dismay, or nods in approval, or if I'm just entirely on my own.
It has one m2 slot filled with an NVMe ssd: https://imgur.com/OppB5ZF
But if I flip it over, there appears to be a second! https://imgur.com/xycOgIw
If I've understood correctly, that means running the recommended 4x ngff riser is a possibility: https://www.aliexpress.com/item/M-2-NGFF-NVMe-KeyM-2230-2242-2260-2280-To-PCI-e-16x-Riser-Card-Cable/32830809871.html
I've got a 200w atx power supply to dedicate to my GTX1060 card, and my computer runs Windows 10 pro with an American Megatrends BIOS.
Does it look like my ducks are in a row to fire away with this purchase, or have I misunderstood/overlooked something?
Someone here knows more than I do, but I would not assume the second slot works until trying it out. Also I would imagine that the extra m.2 slot would have a shared bus/lane with the primary slot. so that would limit the bandwidth of your eGPU. 200 watts should be good for the 1060 but make sure to power 6pin and riser off same power supply. Never heard of that BIOS but the less popular computers tend to have fewer BIOS features.
Why don't you stay a while and update your signature and profile so others can track your build and your posts have better context.
One more idea.. if this computer has USB 3.0 you could always set the boot drive from an external SSD and then possibly have better bandwidth for your at least one working m.2 slot to run the eGPU 1060.
Thanks for the headsup and idea for running an external SSD.
I'm especially confused by the serial ata port options. Which there are 7 listed in the bios, all exactly the same other than the port number. Yet all I see on the motherboard is 1 serial ata port, the two nvme ports, and the one ngff wifi. I don't notice any configuration options for any of these ports in the bios, although it clearly recognizes my main ssd that's in one of them.
omigosh, the riser arrived and everything is working beautifully!
I had all the trouble shooting guides open to all the spots I was expecting to get errors, but after a relatively easy install, I started the computer and everything worked with no fiddling or adjusting. Amazing. GPU-Z says it's running a bus of x4 3.0.
The signal does drop every once in a while which turns off my display for half a second, but I think I can tolerate that.
Is there any other software I should be running to test/configure things, or is it all just blind hope for a bios setting?
For the cables maybe consider getting a small ITX (mini? micro?) case that will fit everything and re-mount inside that case. You should download geekbench64 or valley or cinebench. find someone here with a similar build and compare benchmarks to what they have listed. I think you should try and find out how the internal bandwidth (PCIe?) bus is shared. For example does the NVME drive with the OS impact the performance (not just the GPU-Z rating) of the eGPU? What monitor did you use, which port /cable on the eGPU?
As for the BIOS I don't think its uncommon to have ports listed that are not actually available (although they are usually greyed out). maybe it is set up to accept a SATA port multiplier for up to 7 devices. For me, messing with BIOS settings wasn't something necessary for eGPU stuff. For your build, I don't think you will be spending much time there.
