its been a common feature since 10 or 15years ago, but it mostly depends on the motherboard manufacturer whether they include said features.
all manufacturer gives these said features but most likely the high-end boards will but the low-end boards rarely does.
"
quit without saving" would result with bios going back to its previous setting, you need to "
save and exit" for the changes to take effect.
in cases where the settings is unstable enough to render it bootless, theres a simple reset pin to forcefully change bios settings back to factory default.
undervolting will not damage the CPU, nor does capping the current.
if stability is preferred you can do some stress tests on various voltage points and find the instability point, choose the voltage point you deem safe.
edit: i just noticed this after reading through news feeds.
http://www.anandtech.com/show/7851/intel-xeon-to-get-crystal-well-e31284l-v3seems like its your best bet a a good CPU unit, albeit gonna be pricy but having an IrisPRO on a low-power xeon would be worth it.
The CPU is set at 11GHz >__>
Also I heard that the new unlocked devils canyon chip runs hot(at least the i7 k variant), like hotter then haswell which if I remember right it ran hotter then Ivy...
they're just selecting the highest multiplier ratio, that bios is actually sandybridge as well. doubt it'd even boot at that setting.
they could've possibly got a bad chip, although not defective in a sense.
though it clearly shows just how much these chips aren't limited by the TIM or delidding it gives much benefit.
if you look up the laws of physics its actually the die-size thats at fault.
http://en.wikipedia.org/wiki/Thermal_contact_conductanceOne may observe that the heat flow is directly related to the thermal conductivities of the bodies in contact, k_A and k_B, the contact area A, and the thermal contact resistance, 1/h_c, which, as previously noted, is the inverse of the thermal conductance coefficient, h_c.
to give you an illustration.
