OverDrive® Processor Upgrades
The table below describes support for 320-pin PODP 3V-XXX Intel OverDrive processors which can be accommodated in the Advanced/ZP 320-pin Type 5 socket. The table lists the jumper settings required for the selected OverDrive processor. These OverDrive processors select their clock ratios internally and do not use the baseboard's internal clock ratio jumpers. These OverDrive processors also work over a voltage range that includes both VR and VRE voltage ranges, therefore the user does not need to change the voltage specification jumpers on the baseboard.

For any particular baseboard, the type and speed of memory and/or the speed of the cache components that are used may limit the maximum achievable external CPU clock speed. Use the current external CPU clock settings as a guide in selecting a compatible selection for a Pentium OverDrive processor speed.

The Advanced/ZP baseboard has a 320-pin Type 5 Zero Insertion Force (ZIF) socket which provides users with an OverDrive processor performance upgrade path. The OverDrive processors may provide performance beyond that delivered by the originally installed Pentium processor.

OverDrive Processor CPU Type	Original CPU Type	External CPU Clock Speed	External CPU Clock Switch 7	External CPU Clock Switch 8
PODP 3V - 125 MHz	75 MHz	50 MHz	Off	Off
PODP 3V - 150 MHz	90 MHz	60 MHz	On	Off
PODP 3V - 166 MHz	100 MHz	66 MHz	Off	On

Real Time Clock Battery Replacement
The battery can be replaced with a Sanyo CR2032, or equivalent, coin cell lithium battery. This battery has a 220 mAh rating.
