Problems with overclocking 1660, how to solve?

Question

Video cards

All health.
The card is a gigabyte 1660 with three valves, the case is zalman, also covered in coolers. I drive the memory to + 999mhz, everything is ok, under a load of 65-70 degrees, I add another + 1mhz and it hangs tightly. Is she locked up? Googled, Googled, Googled. Either articles from 5 years ago that no longer work, or nothing useful, the question in the search engine was not formulated as soon as it was. The GPU is chasing +130mhz, but the memory behaves like this even without overclocking the GPU

Answer 1

Rzagon rests on memory chips. Depending on their characteristics, manufacturer, etc... so your situation is quite real. We stop at a frequency where there are no glitches and artifacts, and that's it
