Haven’t had time to sit down and test this properly till this morning before load shedding. This is only a 100% HCI validation, but so far it’s looking like 7400C34 at 1.395 VDD and 1.305 VDDQ is doable. This obviously depends on the board, your IMC, and your kit bin. I can already tell you off the rip that I again pulled an unlucky chip and an unlucky kit so these settings should be doable on basically anything that functions electrically.
