  • Page 23: Chip-Set

    Chip-Set The chip-set comprises three chips, each encapsulated in a 208 pin plastic quad flat pack (PQFP) package. The PCMC chip (SiS 5511) is a combined PL/PCI bridge and cache controller and main memory controller and PCI arbiter. The PLDB chip (SiS 5512) provides the PCI local data buffer and PCI-to- Processor-Local bus data path.

  • Page 24: Cache Memory

    The L2 cache memory, when fitted, also has a 32-byte line width. It is controlled by the PL/PCI bridge chip in the system board chip-set. A single HP cache memory module consists of 256 KB of direct mapped, synchronous pipelined burst, static random access memory (SRAM). The synchronous cache memory module produces 10% better performance than the asynchronous module.

  • Page 25: Main Memory

    Main Memory There are six main memory module sockets, arranged in three banks (A to C), allowing installation up to 192 MB. One bank is already occupied by the pair of memory modules that contain the 8 or 16 MB of memory that is fitted as standard (depending on the model of the computer).

    It is a purely subjective effect. However, in general, the use of this display with the HP Vectra VE 5/xxx series 3 is not recommended. If the user is determined to use this combination, though, then decreasing the refresh rate or the video resolution, or both, may diminish the effect.
