Posted by: SLDW Technology TLH

My golden Intel Pentium 90 MHz overclocked to 100 MHz and raised VCore to 3.4V in order to meet the minimum specs of my SOYO 5EMA+ Super 7 motherboard. No crashes - but without raising it's VCore it has shown typical undervolting symptoms.

I'm not sure if CPU-z detected everything right. For example, I doubt that my P54C Pentium was manufactured with 350 nanometers? Because according to this page and Wikipedia, this CPU was manufactured in a 600 nm process... 		Intel Pentium 90 MHz
