OverDrive® Processor Upgrades
The table below describes support for 320-pin PODP 3V-XXX Intel OverDrive processors which can be accommodated in either a 320-pin Type 5 socket or a 321-pin Type 7 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/AS baseboard has a 321-pin Type 7 Zero Insertion Force (ZIP) 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 Jumper J8F1
PODP 3V - 125 MHz	75 MHz	50 MHz	pins 1-2, 5-6
PODP 3V - 150 MHz	90 MHz	60 MHz	pins 1-2, 4-5
PODP 3V - 166 MHz	100 MHz	66 MHz	pins 2-3, 5-6

Graphics Memory
The Advanced/AS baseboard has 1 MB of Fast Page DRAM installed for graphics and two SOJ type sockets for upgrades up to 2 MB of graphics DRAM. The user can install two 256k x 16, 60 nS DRAM to provide a total of 2 MB of graphics DRAM. The DRAM may be either EDO or Fast Page mode, but no performance advantage will be seen with EDO.
