Overclocking early stepping Northwood cores yielded a startling phenomenon. When VCore was increased past 1.7 V, the processor would slowly become more unstable over time, before dying and becoming totally unusable. This is believed to have been caused by the physical phenomenon known as Electromigration, where the internal pathways of the CPU become degraded over time due to excessive electron energy. This was also known as Sudden Northwood Death Syndrome.
im not so sure if this is the case with my CPU because everest says that my CPU is already running at 1.75 vcore and it's never been overclocked and never went bad and i've had it for four years. And i think it's not a northwood core its a willamette.

ok for somereason i cant get a photo to upload. so ill just copy what it says in everest.

Willamettes are the oldest P4's. They default 1.700-1.750 depending on their speed.
