PB470 CPU Upgrade Information

Warning Only authorized service personnel should upgrade the system. Anyone who wants to upgrade the system herself/himself should know about the dangers of ESD (Electro-Static Discharge) and the necessary precautions. Unknowingly zapping the components of the computer will void the warranty.
 

Note
Uses 237 pin type 3 socket. To open the upgrade processor socket, pull the tab/lever straight up from the side of the socket (closest to the back of the motherboard) and pull towards the front. The following jumpers are used:

Note
Intel refers to the P24T as the Pentium OverDrive Processor or PODP The DX4-120 CPU requires a 486 system to be able to run at 40 MHz clock speed. None of our motherboards have been qualified to run at that speed. However, they will run at 33 MHz which will yield 100 MHz DX4 speed.
