Would an ADT-Link R43SG transmit data at PCIE 4 speeds if both the GPU & M.2 slot were PCIE 4?
With the latest GPUs' being gen 4 and because 11th gen Intel laptops could have a gen 4x4 M.2 slot would the ADT-Link R43SG setup run at 32Gbps or 64Gbps?
I have heard that high quality gen 3 cables could transfer at gen 4 speeds but not sure at all about if this is accurate.
Do members of this forum have any contact with ADT-Link to know if they would work on a gen 4 version?
I'm particularly interested in the doubling of bandwidth as I would really like to use the internal display of the laptop without running into a bottleneck rather than having to use an external one.
Thanks for reading.
@mqyrk, This is something I meant to test on several occasions. First attempt was with an Intel Evo laptop that has Thunderbolt 4 and a PCIe 4.0 M.2 slot. I couldn't get the laptop to boot with the R43SG adapter connected. I'm going to try with another Intel Evo laptop soon. Another backup plan is through an ATX motherboard, Gigabyte Vision D B550.
It might be possible. The length may need to be shorter. The only thing stopping gen 4 speed is the quality of the cable. PCIe does link training to see if each lane can do gen 4 reliably and if not, it falls back to lower link rate. Sometimes this link training causes issues so people limit (in BIOS) the target link rate to gen 3 so that PCIe doesn't even try gen 4.
I have a gen 4 source (HighPoint SSD7505) but haven't tried it with ADT cables or M.2 to PCIe x4 adapters.
Maybe one can set gen 3 in BIOS, then use pciutils to retrain for gen 4? I do this to get gen 3 or gen 4 devices to work at gen 2 speed in my Mac Pro 2008 which defaults things above gen 2 to gen 1.
@cardant, Yes, I tested the ADT-Link R43SG adapter (50cm cable) with a Z490 Vision D motherboard a few weeks ago. Unfortunately it could not negotiate a PCIe 4.0 link. I manually set the Link in BIOS to PCIe 4.0 as well but the best was gen3.
@itsage, Is there an ADT representative that visits the forum or are there any people who are in contact with them?
With more and more laptops and gpus' with PCIE 4.0 in the future it would be great for them to upgrade the R43 from PCIE 3.0.
@mqyrk, I'm not sure about ADT-Link presence in our community. I agree upgrading to PCIe gen4 on this M.2 eGPU adapter would be excellent!
Good news. ADT-Link (CN) advises a Gen4 adapter will be available next month:
