DP55WB board UEFI enabled problems

I enabled UEFI and AHCI in the firmware on the DP55WB board and then installed Windows 7 Pro x64 (which created the MSR and ESP partitions). Everything seemed to install fine but I'm having a few minor problems. First it seems that there is no power management enabled as CPU-Z shows only the CPU frequency at 2800 Mhz with no multipler, bus speed, or rated FSB at all. I have the power settings in Windows to "Balanced" so the CPU freq should go down to 1200 Mhz on idle. [url=http://www.intel.com/design/motherbd/software/idu/]Intel Desktop Utilities[/url] will take a long time to load up and it doesn't show any information related to my system at all (e.g. temperatures, fan speeds, voltages).

 

Also when the Windows and UEFI splash screens come up I seem some random numbers and underscores (e.g. "94_") as an overlay. This is a minor problem but it seems to be something with the firmware.
