yea its only visible under stress testing . i foolishly didnt notice the rail voltages in hwinfo.voltages are dropping below limit under full stress test.while playing compatitive games its not visible .
as a result 'turbo' has gone bad on my mb. by which i mean ,i have to play at stock cpu and pcle clock frequency. did check for weeks . all turbo is disabled.bclk turbo also disabled. if i turn on anything related to turbo games will desync.i suspect vrm circuit maybe affected by my old bad psu.


intersting thing i notice if i turn on bclk turbo ,valorant a cpu intensive game wil desync or lag more than gpu intensive games like marvel rivals or apex. both will lag but its more noticeable in cpu games.
