Lol, thank you for the update rammsteiner. It made me realize that im on 2250MHz HT speed atm.
Still trying to install 64bit debian here. It worked once with above settings but froze on the second try. Trying to stabilize it with higher CPU and NB VID's atm.
In 1066mode 225 seems to be the stable limit here. 227 boots but freezes soon.
I use relaxed timings and try to find the lowest voltage for the mem at this frequency. With the 3-07 bios i got 4-5-5-15 timings up to ~580MHz at 2.3V during first tests.
