I see where is this all leading to.
To be clear, Intel didn't "lock down" bclk.... they just linked more components to it to reduce cost and complexity.

Of course, the side effect is that overclocking with the bclk is now limited by the component that overclocks the worst.... which means only a few MHz flexibility.

but other than that, intel are slowly pushing the OC crowed out or at least crippling it's abilities to spend more on a proce$$or .
This is on package level and eventually on die.... overclockers don't usually mod package traces, repair blown fuses, laser cut dies, or program microcode.

My worry with this is that the VRMs are often the hottest part on the motherboard, integrating them into the CPU will probably limit overclock potential because we wont be able to cool down the whole CPU enough to really push extreme clock speeds. It would be nice if Intel would make a CPU on 22nm, but make it takes up just as much die space as a 90nm equivalent CPU. Cost would be enormous since it wastes so much space, but it sure would be a lot easier to cool with all that blank space between heat generating parts. We may be almost at our limit of process node shrinks, but we are most definitely at our limit in conventional cooling technology. The die's are just becoming too small in surface area to cool with a big heatsink.

for the sake of the holy 9 GHz, we are the Enthusiast overclocking crowd. We always can find a way to overclock (and thus spending more money biggrin.gif ) no matter what. We are the same people who weren't satisfied with the plain square heat-sink and wanted more. We are the same people who weren't satisfied with the best of air cooling and thought of not only to use water to cool our overvolted processors and graphics cards but also made it look elegant and inspiring. We are the same people who made the oil PC tank and are using liquid nitrogen, Phase Change, TEC and more just to crank our CPUs even more and we always find a way. So if we take apart a processor (ivy deliding) just to push it further i'm sure we'd find a way to push Haswell no matter of whatever limitation we'd encounter on it.

That means the socket is passing 250A through its power pins. If you're putting 12V to through the socket to the onboard regulator, you'll only need ~32A through the pins for that same amount of power (assuming 90% VRM efficiency). You could reduce pin count since a LOT of pins are currently used solely for power and ground or use those freed pins for more I/O. Either one is good.

Either way, you still have to deliver the WATTAGE to the CPU through the pins ... be it 250A at a lower voltage or 32A at a higher voltage.

Higher voltage/ lower current means less heat loss to Resistive loss in the conductor= Resistance*Current^2

Thus raising Voltage by a factor of 10, reduces Current by a factor of 10 and reduces the Resistive loss by a factor of 100.

Also from the original quote

Know anyone who has, can reprogram, and load microcode to an Intel CPU? wink.gif


Besides, some of the hardware is physically disabled anyways.
