I'm assuming that your CPU runs @ 2200Mhz standard?
If your CPU multiplier is unlocked then you should achieve 2800Mhz with an FSB of 200Mhz and the multiplier set at X14.
At the moment the Multiplier is set at X11. And you probably ramped up the FSB to 228Mhz?
Also will your RAM run @ 912Mhz?
An FSB of 218Mhz seems fine and that means your RAM is running at 72Mhz above it's stock speed.
And update the BIOS only if you need too.
