Cyrix 6×86/6x86L CPU
Cyrix rates the speed of their processors as a megahertz-equivalent performance level based upon industry-standard benchmark comparisons to the Pentium? II processor when tested in equivalently configured computer systems. In the table below, the Cyrix CPU designation is followed by the internal CPU clock speed. For example, the PR-150+ has an internal CPU clock speed of 120 MHz.

Upgrades

• Cache Upgrade. The 992 motherboard comes with 0, 256k or 512K Level 2 cache. The cache is not upgradeable.

• CPU Upgrade. This motherboard can accommodate the following CPUs:
  • Intel Pentium P54C/CT/CS/CQS, MMX
  • Cyrix 6×86/6x86L/6x86MX
  • MII microprocessor
  • idt-C6 microprocessor
  • AMD-K5/K6/K6-2
  • Zero Insertion Force (ZIF) socket. Uses the 321-pin Type 7 CPU Socket. Not keyboard switchable. Disable cache to slow down the system.

• RAM Upgrade.
  • Maximum on Motherboard: 256MB
  • Uses 8/16/32/64/128 MB DIMMs, 60ns or faster EDO SDRAM DIMMs
  • Supports only non-parity DIMM modules.

Notes – The 168-pin DIMM sockets will accept 3.3V 1MBx64 (8MB), 2MBx64 (16MB), 4MBx64 (32MB), and 8MBx64 (64MB) and 16MBx64 (128MB) DIMMs. Bank 1 will be populated as the default from the factory. No configuration jumpers: BIOS detects memory size, and memory type. This motherboard will not accept 36-bit DIMM modules (parity).
