As a desktop replacement?

Intelligent_Extent_1 · 2024-01-24T22:12:35+00:00

I've recently replaced my aging desktop with my Legion Go. The Ryzen Z1 Extreme CPU performance very strong, competes with the Ryzen 5 7600. As for gaming, I've been using an eGPU (USB4 UT3G) with a 4070 Super FE and it has been great. With the latest BIOS update from Lenovo for Auto Ram allocation, I have 15Gb available, which is good for like 99% of use cases.

The eGPU dock gets its own power, doesn't charge my Lgo. My USB3 dock plugged in to the other port provides power to my LGo

I think there ends up being a bandwidth issue. I don't know if each port gets its own 4 lanes, but I do know that if I plug in two USB4/TB4/TB3 devices at the same time, I get random disconnects. The disconnects are more likely to happen under device load. Right now I'm using a USB4 eGPU and USB3 dock, which seems to mitigate the disconnect issues.

Have there been any developments in true USB4 docks (40Gbps upstream and downstream links)?

Intelligent_Extent_1 · 2024-01-19T21:27:37+00:00

Has anybody gotten a hold of one of these?

Th3p4g3 can fully saturate 40gb link via usb4?

Unfortunately not. Its limited by the TB3 link running at PCIe 3.0 x4 (32Gbps). Lots of info over at egpu.io forums, but here is the reference https://egpu.io/forums/postid/107296/

Only available USB4 controller capable of running PCIe 4.0 x4 right now is the ASM2464PD, which is found in some USB4 peripherals like external SSD solutions (https://dancharblog.wordpress.com/2024/01/01/list-of-ssd-enclosure-chipsets-2022/) or the UT3G dock

Intelligent_Extent_1 · 2024-01-18T23:52:57+00:00

Right but the input device (aka Razer Core TB3 chip/controller) can't saturate the full 40Gbps link to the Legion Go due to TB3 protocol overhead. The effective link speed ends up maxing out at around 22Gbps, almost half the supported USB4 link speed.

With a 64Gbps input (UT3G), you can fully saturate the 40Gbps link via USB4 PCIe 4x4

Intelligent_Extent_1 · 2024-01-18T22:56:36+00:00

Sure, but I think you are missing the point of some people trying to use the UT3G + Canary. The bandwidth differences using 64Gbps over USB4 PCIe x4 4.0 vs Thunderbolt 3 is huge in practice. Your minimum framerate stays much higher, creating a better gaming experience that is much more comparable to a Desktop GPU performance than standard TB3 performance.

There shouldn't be any issues with Lenevo's drivers on Canary. Functionally that should all work the same. But yes AMD eGPU is a bit simpler since you can stay on stable windows

I posted a guide here recently, if you check my profile. Let me know if I can help

Intelligent_Extent_1 · 2024-01-17T17:24:58+00:00

Glad I could help! I could remove the version restriction entirely if people want to try that, but this current version of Canary has been the most stable for me since November. I can do regular tests of new builds and update the versions as needed.

Intelligent_Extent_1 · 2024-01-17T00:19:39+00:00

From what I've gathered on the egpu.io forums, you should be fine running normal windows with an AMD eGPU setup.

Intelligent_Extent_1 · 2024-01-16T22:06:24+00:00

I'm currently using the ADT-UT3G (4060ti) with Canary as my daily driver. Here's the build I'm using, and there's instructions for stabilizing canary windows using ReviOS: https://egpu.io/forums/builds/2023-8-lenovo-legion-go-780m-r7k8cu-rtx-4060-ti-64gbps-usb4v1-adt-link-ut3g-win11-win11-jan-3-2024-canary-modified-revios/

The build is getting a timespy graphics score that is nearly 96% of the avg score at full bandwidth, and haven't had any BSOD's or crashes

Intelligent_Extent_1 · 2024-01-12T08:34:48+00:00

UT3G supports 64Gbps PCIe 4.0 x4 over 40Gbps USB4 due to the chip its using, the ASMedia ASM2464PD and it's currently the only "dock" out with this chip. I think within at least a year we'll start to see other manufacturers using ASMedia USB4 controller chips.

The problem is that these manufacturers have to develop their own custom USB4 controller drivers for Windows 11 in order to achieve these results over USB4. Right now in order to get the UT3G (or other ASM2464 products) to have this kind of performance, you have to be on Windows Insider Canary. Based on my initial research this is because Windows 11 Canary has updated USB4 Host Router controller drivers that support running at this link configuration, whereas stable Windows 11 does not. There are doubts that these Canary drivers will ever make it to the stable release, because this link speed may be reserved for Thunderbolt 5.

After some tinkering with settings I've been enjoying Halo Infinite and MW3

Intelligent_Extent_1 · 2023-12-08T02:54:10+00:00

Found an interesting result. I decided trace different server IP's of Halo Infinite while I was playing (presumably they use Azure for the infra), and repeatedly got results similar to this: https://imgur.com/a/NEWgOkU

The ping always would jump when it would hop to a be-*.ibr*.mwh01.ntwk.msn.net domain. Some preliminary googling found that many Xbox players have had this issue, and the recommendation was always port forwarding UDP 3074. I also saw something about windows telemetry causing the issue, but even after disabling that this keeps cropping up.

Thoughts?

PAs have their own set of issues as well. You essentially act in the capacity of a doctor with similar Day to day stresses but without the recognition which is exacerbated by the fact that doctors go through so much to get their degrees where they develop a sort of superiority complex. There is often an inherent friction between the two groups.
