@ kegobeer, that may be due to Dell's specialized BIOS settings, OEM's have a very controlled BIOS. Might be a laptop thing also.
On my custom build, High Performance will make the CPU run at full speed, frequency, all the time. The Balanced settings allows EIST, speed step, to work correctly.
@ BradJorgensen, try the Balanced setting and check if EIST is working correctly.
Does the default power saver, allow full power when needed?
