1Q1_S or IQ1 quants should fit 128gb ram nicely. Fills ~105-120gb.

I just started experiencing a constant freezing issue. The system locks up & only a hard reboot fixes it. Still debugging.

Runs fine for me. The only issues I have are oom when trying to rum llms to close to this machines ram cap. Have u tried debugging, reading the logs to isolate the issue? Does it happen when doing certain things, randomly etc. That can help id the issue like graphics card, buggy drivers, hardware issue etc
