I wholeheartedly welcome everyone! Sorry for my English, the translator helps me)))
Problem: No image after Windows logo, freezes. Initially, it came with a hub in a bag and a blackened 1.35v driver (powered by gddr6). I bought a new hub, installed it with a clean ME region, an image appeared, and a disc with an exclamation mark in the device manager (code 43). I tested it with MATS, showed errors on 2 banks. An interesting situation is that while at least one bank is not / does not work, the mats correctly determines the card, shows errors on the missing bank. As soon as I put a known-good jar (the last one, all the others without errors) - MATS falls into an error even before the start of the test, while absolutely all the memory heats up, the core voltage drops to 0.63v (before trying to initialize 0.87v) If you try to load Windows, then after the logo there is a black screen, the chip behaves in a similar way.
Board composition:
CPU SRF6U
PCH SR40B
VIDEO N18E-G0-A1
Measurements:
Memory power: 1.35v, 14.8Om
gpu_core 0.87v, 0.2Om
1.8v_vga_s0 - 1.8v, 28Om
1v_vga_s0 (pex_dvdd) 1.05v, 19Om

Question 2:
- Isn't there enough resistance on the 1.8v line for a 1660Ti? On cards with GDDR5, there were more than 800 ohms, but this generation was never encountered ...
- Why is memory getting hot when trying to initialize?
