He has just updated the reason why we know so high now. Seems AMD are on top of things now hence probably why the Twitter post last night to confirm they had fixed the issue.

"The person spilling the beans initially said about 3ghz limits but corrected today saying that AMD very recently forced a firmware update that got the IMC support up to 3800mhz. He did say sadly now though the memory subsettings are gone and all you get is 4 subsets with the dividers to play around with. Basically AMD are pushing the engines up to 100% now."
So 1T prob locked now then I guess.
