Hi Branko,
I've tested the strap on 2 GPUs:
1. Gigabyte GV-RX560OC-4GD - ETH 15.6MHz@2125 and hang@2150
2. MSI RX560 AERO ITX 4G OC - works unstable even at 1950MHz
I've just tested one more GPU:
Adapter 2 (BN=04, DN=00, FN=00, PCIID=00001002, SSID=000022FF)
Asic Family : Polaris11
Flash Type : GD25Q41B (512 KB)
Product Name is : GV-RX560GAMING OC-4GD/FW0/06F3
Bios Config File: RX560GO4.FW0
Bios P/N : P/N Not Available
Bios Version : 015.050.002.001.000000
Bios Date is : 01/07/18 02:14
The result is the same as for the msi aero - works unstable even at 1950MHz
