4. Press the new battery firmly into place.

Cache Upgrade
If you want to upgrade the cache, follow these steps:

1. Ensure you have an upgradeable COAST Cache module compatible with the Packard Bell 660 motherboard.
2. Locate the special CELP socket on the motherboard for the COAST Cache module.
3. If your COAST module is configured with 32k x 64 asynchronous SRAM, insert it into the socket, aligning the pins properly.
4. If your COAST module is configured with 32k x 64 burst or pipelined burst, insert it into the socket, aligning the pins properly.
5. Ensure the COAST module is securely inserted into the socket.

CPU Upgrade
If you want to upgrade the CPU, follow these steps:

1. Ensure you have a compatible CPU for the Packard Bell 660 motherboard. The supported CPUs are Intel Pentium ranging from 75MHz to 200MHz.
2. Locate the 321-pin Type 7 Zero Insertion Force (ZIF) CPU socket on the motherboard.
3. Carefully lift the CPU socket lever to open the socket.
4. Align the CPU pins with the socket and gently insert the CPU into the socket.
5. Close the CPU socket lever to secure the CPU in place.

RAM Upgrades

Uses 4/8/16/32 MB 72-pin SIMMs, 60 or 70ns EDO or Fast Page Mode RAM. Supports only non-parity DRAM.

1. Bank by bank support for EDO or Fast Page Mode DRAM with automatic presence detect for EDO DRAM.60ns EDO required for 66 MHz bus speeds, and 70ns EDO required for  50 & 60 MHz bus speed.70ns Fast Page Mode required for 50, 60, and 66 MHz bus speeds. EDO and Fast Page Mode can be mixed in separate banks.
2. Four 32-bit SIMM sockets accept 4MB, 8MB, 16MB, 32MB in either single or double sided configurations. SIMMs must be added in pairs. SIMM sockets can be populated in any  order.ONE or more SIMMs may be located under the peripheral bay in the Packard Bell “all-in-one” (Spectra) chassis.
3. Bank 0 will be populated as the default from the factory.
4. No configuration jumpers: BIOS detects memory size, and memory type (EDO or Fast Page Mode).
5. Memory voltage requirements : 5V.

Video Memory Upgrade

The PB660 uses CL-5446 Video Drivers. The PB660 has 2MB video memory and is not upgradeable further.
