Interesting to see, that according to this table, 790i ULTRA doesn´t support 2GB modules running at 1800Mhz and at 1800Mhz can only use 2 slots.
So in teory, if we want to run our memory at 1800Mhz,or more,we are LIMITED to 2GB!!!

i´m wondering if someone around here is running 4GB (2x2GB or 4x1GB) at 1800Mhz?
Yep, I am. Linked at synch'd @1800Mhz with 4x1Gb SuperTalent (in my sig). Completely prime95 stable and no hard locks in the 3 weeks I've been using these settings.
