thuban mem controller testing

Also, we have a couple of memory tables left to fine tune for efficiency but with BIOS 0707, be sure to set HT manually (as high as possible) to ensure best possible write speeds as the tables flip above 1800 and HT on auto will fall back to under 2000. In an early beta release, 8GB at 2000 is working but efficiency at 1600 is still much better at this point.

Any reason why the HT link has to be above 2G for better performance?

In regard to the efficiency: I suppose that Thuban still has the same issues as Deneb has when it comes to memory data transfer. AMD people confirmed that an elevated memory frequency is no use if you don't increase the IMC frequency accordingly. An appropriate ratio would be IMCRAM as 3:1, which would mean a 6GHz IMC if you want to make propper use of 2G memory.
