Inside and outside clock speed of 486DX is same. 486DX2 contained double clocking technology increasing inside speed to two times of outside speed. DX3 was a standard that made use of 2.5× multiplier, but it was not released as common product. In IntelDX4, 3.0× multiplier operates.

IntelDX4 supports 3.3/3.45V regular voltage, 2×/3× multiples and 25/33/50Mhz FSB speeds.

‘SK051′ receives 33Mhz FSB speed and 3.45V voltage. It operates at 100Mhz clock speed(3× FSB speed). It cannot support 2x multiple. ‘&E’ means that it is write-through cache version. (If ‘&EW’ is written, the CPU contains write-back cache.)

intelDX4 exactly fits 169pins Socket 1. But It can put 238pins Socket 2 and 237pins Socket 3. Socket1/2 supports 5V. To safely use IntelDX4 on Socket1/2, the motherboard must be able to modulate CPU Voltage to 3.3V.

Previous CPUs generated low heat, so they could use without heatsink. But DX4 was too hot to use without heatsink because of DX4 speed attain to 75~120Mhz. Attaching heatsink and fan on CPU chip is general after DX4.
