2018 15" MacBook Pro (RP560X) [8th,6C,H] + RX Vega 64 @ 32Gbps-TB3 (Mantiz Venus) + macOS 10.14 & Win10 [mac_editor]
Any TB3 Windows notebook would also do. Most of my close friends seem to have 2018 models too. Anyway, it's not an urgent problem, just a slight annoyance.
@mac_editor quick question, did you install windows on your macbook with bootcamp on catalina? or did you already have windows on it when you had Mojave?
@Mac_editor any update on the new Mantiz?
No change in H2D speeds (see Update 4 in main post). Tried a few things but couldn’t get the firmware update going on my system. For now, I’m busy with some other stuff so will get back to addressing this issue later.
@Mac_editor thats super odd, and I winder why mine is different? And whether I should try and change firmware... do keep me posted on any updates! I'm currently trying to sell my 5K finally.
Can you both get the Firmware version number of your Mantiz Venus in macOS System Information > Thunderbolt? I will check mine later today to compare. I believe it’s running the firmware released in July 2017.
Yes, its very odd to see different H2D with same firmware version.
In the generic firmware upgrade tool, I rarely ever got to the point of the enclosure being detected. The Thunderbolt drivers (16x or 17x) have a very hard time detecting the enclosure. Even when I somehow got detection in Windows, the utility would fail to flash anyway (SDK_UNKNOWN_CHIP).
Will do, will have to be tomorrow though, but would be great to try and get to the bottom of this...
@mac_editor I went through all the builds with a Mantiz Venus and found only two other instances with low H2D speed. They were both 2017 15″ MacBook Pro. Here’s one by @Lacin and the other by @Rycco. They were prior to the release of the new firmware however. I can’t imagine two units you received were running older firmware. If you have access to another Thunderbolt 3 computer that would be great to determine whether it’s the enclosure firmware issue.
Appreciate the effort! Thank you. I am not really sure what is going on here. I also tested bandwidth without any peripherals and SATA drive connected - same dice. Is your firmware version 25.1 as well? If so, this is a complicated situation of two different versions labeled the same. I noted that some Mantiz builds did not test bandwidth. Mantiz support isn't helpful if they say firmware cannot be upgraded on 2018 MBP (why can I upgrade an Aorus then). I mean if you know your software doesn't work on the 2018 MBP, get it working (in unofficial capacity just as with 2016-17 MBP). I will try with a friend's 2018 MBP and see what results I get on their system.
