Battery

The RTC battery is upgraded by removing and replacing it with a Lithium 3v CR2032 or its equivalent battery in socket BT8J1.

To remove the battery, locate BT8J1 battery socket on the motherboard. Use an index finger and thumb from one hand, grip the battery at opposite points. Lift the battery out of the socket.

Take the upgrade battery, insure that the flat surface is facing up. Snap it into the battery socket. Note - + Positive side faces up.

Cache Upgrade

The cache is not upgradeable.

CPU Upgrades

This motherboard utilizes the Socket 7 (U25), which is a staggered 321 pin Zero Insertion Force (ZIF) socket. This motherboard is designed to be upgradeable with any pin-compatible Intel® Pentium™ processor, AMD or Cyrix M II™ processor, including, but not limited to, the following:

  • Intel P54C 200/66, 166/66, 150/60, 133/66, 120/60MHz
  • Intel P55C-MMX
  • Cyrix 6x86 150 and 166MHz
  • AMD PR 100, 120, 133, 150, 166MHz
  • AMD K6

The AMD K6-266 and above require a CPU voltage setting of 2.2 volts. This voltage setting is not supported on this motherboard. Do NOT attempt to upgrade the CPU on this motherboard with any AMD K6 processor 266 or above.

The Cyrix M II 266 is NOT a 266MHz processor. Use the settings listed for a 200MHz processor. These settings are also printed on the surface of the processor itself.

RAM Upgrades

The Motherboard has two DIMM sockets configured as two (0-1) banks. The system memory is upgradeable to 128MB. The 168-pin DIMM sockets will accept both 3.3V as well as 3.5V 1MBx64 (8MB), 2MBx64 (16MB), 4MBx64 (32MB), and 8MBx64 (64MB) fast page DRAM DIMM's or extended data out DRAM DIMM's with the recommended access speed of 60ns or faster. This motherboard will accept either single or double sided DIMM's. Memory type, size, and speed can vary between sockets. This motherboard will not accept 36 bit DIMM modules (parity). Due to the nature of the VX controller chipset, this motherboard will not support 128MB DIMM modules.

The only 64MB DIMM that is approved for the 810 is Packard Bell part number 965174.


Video Memory Upgrades

PB810 - The Motherboard has 2 MB Video Memory, and is not upgradable.
PB820 - Can be upgraded by installing another 1MB of Video Ram.
