I'm sure you are correct here. Currently at -600 -600 -75 and running strong. lol -75 for cache is active though, as a setting any lower causes a freeze. CPU and GPU appear not to be active, as -600 is likely unrealistic.Did some further research after I thought a bit about this. 250 is the maximum range of the under/over-volt registers, as they're only 8-bit on the Dell. So unless there's a super-resistant die lattice out there, it's likely that you've just not enabled the registers for overclocking (which in turn should enable undervolting).
Also - and more pertinently, there should be higher GB scores with each step you undervolt, as you are further away from the TDP ceiling. What are the GB differences, say at 0, -125, -250?
How do I go about enabling undervolting in the BIOS?
