PB660 RAM Memory Upgrade

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.
 

Specifications

Standard on motherboard: 8MB Installed.
Maximum on motherboard: 128MB Maximum.

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

Note

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" (Spectria) 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.

PB660 Cache Upgrade

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.
 

End user units include a special CELP socket for an upgradeable COAST Cache module.

The CELP (Card Edge Low Profile) upgrade option conforms to Intel specification #1.2 for COAST (Cache On A STick) cache modules.  The CELP connector supports 256k COAST modules using asynchronous, or burst and pipelined burst SRAMs.  Burst and Pipelined Burst SRAMs must meet the functional and electrical specifications documented in Intel's Pentium Processor Burst SRAM Specification booklet, revision 1.0.

COAST Modules Supported

There are two COAST module configurations supported:

1.    Modules configured with 32k x 64 asynchronous SRAM with a 5v 8k x 8 SRAM Tag SRAM.  Eight 32k x 8 3.3v SRAMs are used for the Data RAMs (all are contained on the COAST module).
2.    Modules configured with 32k x 64 burst or pipelined burst with either four 32k x 16 or two 32k x 32 (no parity) SRAMs (also located on the COAST module).

Commercial units have 256KB of Cache soldered on board which is not upgradeable.

Purchase Referrals

End users should contact Intel at (800) 538-3373 for a referral to a dealer who handles Intel products.
