Hi guys I have one question.
Since July 2018 I was using on my MBP11,3 (2014) a samsung 970 evo 1TB (without refi modded), Blackmagic shows ~1300MB/s and system was stable.
One week ago I start to receive panic log and reboot everyday with more frequency (especially with safari open), Blackmagic shows now 300MB/s.
So I tried to use an AHCI apple SSD 128GB (SANDISK from a MacBook Air) to update the bootrom (installing Catalina) but the problem with the 970 evo persists (with the AHCI SSD all ok).
So I thought that the SSD was broken and I got a Sabrent Rocket 2TB, I tried a fresh install of Catalina, but I received the same problem, panic log and speed ~300MB/s, sometimes ~600MB/s
So I have bought the ch3140 and I flashed the modded bootrom following the CMD+Q guide (ver. 158.0.0.0), the situation is slightly better but the speed is now 300MB/s in writing and 600MB/s in reading with the sabrent (system info shows x1).
Meanwhile I read that the chenyang adapter is problematic and I have a chenyang adapter.
Now I ordered a Sintech adapter to make another try and also a SX8200 2TB.
Do you think that the chenyang adapter can burn the pcie chipset? But the AHCI SSD works without problem.
If I'm not wrong on the logic board there is only the PCIe chipset that works for both (NVME or AHCI chipset are on the SSD). It is right?
