Core i7: high leakage & average chips @ low VID & high VID

[Sparda]

I just got an interesting chip that draw more current than a normal one so I might share something here. Well people might call them hot chip/high leakage chip whatsoever. I was never lucky enough to got one before that is very noticeable. When I set at 4GHz (HT on) nothing fishy going on but I did notice it a bit hotter than normal one.
idle .......load

When I set 4.5xGHz(HT off) the idle temp smells. I thought it the IHS but after 4 remount it still the same. Then I watch the watt meter and the power draw from the system is higher than before I swap the cpu.

215x21 bios-1.4375V
idle (283 Watt) ........ load (424Watt)


And below are ss from the average chip.

217x21 bios-1.475V
idle (250Watt) ........ load (397Watt)

The VID of the leaky one is 1.19375V and the average one is 1.25625V. Both oc pretty much the same but I got hard time setting the leaky one at 217x21 on prime given that every chip is different due to fabrication process.
