More NVMe slots? OCuLink is the current future!

Some of you may have heard of the new upcoming GPD G1 eGPU that can be connected with OCuLink. Thin, sleek, totally doesn’t look like a 2nd PC.

As of now, OCuLink provides a much better performance for external GPUs. Yes, Framework’s mainboards don’t have OCuLink to begin with. That’s where the NVMe to OCuLink adapter comes in. I was kinda bumbed that, from what I see, the mainboard has only 1 NVMe slot. Could’ve been so much easier to have 2 slots, one for storage and the other for OCuLink. Guess I could just use an NVMe enclosure for storage instead.

My point is, with the new GPD G1, you can get an extremely portable gaming setup going on ETA Prime has videos pairing it with mini PCs and they absolutely rock. And DIY Perk’s video using the Framework mainboard to create a 3-screen portable beast shows the amount of things you can do with it.

Can’t wait for the future of Framework! Also, we want 2 NVMe slots, please!! And if I weren’t asking for too much, an OCuLink port too haha!

Framework 16 has two NVMe slots, FW13 has one.

You didn’t mention, but I have to presume you are talking exclusively about the Framework-13. Since the Framework-16 has 2 NVMe slots and also exposes PCIe with its expansion bay, making OCuLink easy via an expansion bay adapter, which at least two people are working on seperately.


Oh, I was speaking about only the mainboard without the other components. Can’t seem to find a mainboard only that has 2 NVMe(s), or am I not looking hard enough… and the catalogue filter under “Framework Laptop 16 - AMD Ryzen™ 7040 Series” says 0.

The goal is to 3D print an enclosure that accommodates an OCuLink adapter through NVMe. Think of it as a mini-pc to eGPU to external monitor

The Framework Laptop 16 is upcoming, now available under preorder. Currently, expected to ship late Q4 2023. Production will initially go towards full laptops, with separate mainboards being made available sometime later. It has 2 NVMe slots and an expansion bay connector that has PCIe, as well as power and USB 2.0. If you can wait I’d suggest using it instead.

I don’t think OCuLink will be the future of eGPU. Intel just announced thunderbolt 5 standard (, it has 120 Gbps bandwidth, 3 times of current thunderbolt 4 standard. This will definitely open up the eGPU market agin.


Still only 64gbit for the pcie link (vs 32gbit on tb4), the 120 is for the non symmetric mode (120 in one direction and 40 in the other instead of 80/80), probably mostly for displays. The pcie4x8 of the framework 16 is still quite a bit faster than that and the occulink solutions are going to be a lot cheaper but well no hotplug.


OCuLink is not necessarily incapable of hotplug. Was there ever a confirmation that the Framework 16 does not support PCIe hotplug on the expansion bay slot?

Occulink with pcie hotplug would be a holy grail on the 16 but unfortunately egpus are a pretty small niche and occulink ones are an even smaller niche withing that so unfortunately I doubt framework will commit the engineering resources to do that anytime soon, especially since they outsource the bios, would be awesome if they did though.

PCIE is not hotplug unless it explicitly is, it needs special consideration (in hardware and software, some of the hardware side for the 16 could probably be handled on the expansion card though) and is relatively rare even in servers these days (especially since the shift from replacing parts in running servers to replacing whole servers at a time).

TB5 is amazing news!

Also, I just want an extra nvme slot for the oculink converter, no hotplugs. My whole plan (if I were to go for it) is to just 3D print my own enclosure for the motherboard, 1 nvme slot for storage and the other for oculink. It’d be a fun little project.

Will there be USB4 80gbit (thunderbolt 5 not for obvious reasons) support for the current framework 16 without motherboard replacement? Because the port framework has on the back is capable of 80gbit speeds?

Unless amd secretly put an 80gbit usb4 controller into the chip and just didn’t tell anyone about it probably not (would be cool though).

An 80gbit usb4 add-in card would not make that much sense if it is even possible (you don’t have display out on the expansion bay connector and that is required for usb4, at least if you want to meet spec).

Honestly, if we can add an oculink board to the current nvme slot, and have an SSD (perhaps 2230 ?) in one of the expansion slot, it’s a win/win.
Even more so if the oculink port can be moved to one of the other expansion card, i personnaly only need 2 type c so …

Also, we have to wait and see on the AMD USB4 implementation and new gpu docks for said interface, but oculink is better as it’s pretty much open source

idk if the bandwidth gain from a pcie4x4 link is worth the drawbacks over usb4 but the 8x on the 16 definitely might be.

Blockquote More NVMe slots? OCuLink is the current future! - #14 by Adrian_Joachim

Not sureif the quote is working, but yes i agree on that, apprently the usb4 implementation by amd can go up to 4 gen 4 pcie lanes, which i guess is enough for most users (or 1440p egpu). but the 16 inch interface is way better and less restrictive
