Well pal.. 2225MHz is the limit of my Barton. 222x10 or 202x11 or 185x12... thats the best the chip can do.
Yep, i have 2x256MB set-up in Dual Channel. I know Dual Channel is very demanding, but i want to use it too... so i have never tried OCing without Dual Channel
And 2312MHz at Vcore=1.55V is very sweet
Many Congratulations!!! Take that baby to the limit and do keep us informed
