Its not letting me break the 4.5GHz barrier....

========== THIS IS WORKING ==========
BCLK: 144
CPU Ratio: 31 (4462 MHz)
DRAM Freq: 2020 MHz
UCLK Freq: 3032 MHz
CPU Volt: 1.375
QPI/DRAM Volt: 1.40

========== THIS IS NOT ==========
CPU Ratio: 32 (4608 MHz)

I guess I'll fiddle with the settings (lower BCLK, raise CPU ratio, etc...) to try and come in closer to 4501 MHz...
