BIOS
Dell's BIOSes, even on XPS models, don't allow any user-defined adjustment whatsoever. The BIOS is only useful for checking system attributes. It's a shame as the XPS line is marketed as being designed for the gamer/enthusiast.
'None of these fields is changeable' is popular with Dell.
DDR2 running at an effective 533MHz. Note that you cannot examine system or CPU temperature from the BIOS.
Alas, at stock it will remain.
