Upgrades
Cache Upgrade. The 911 motherboard comes with 0, 128K, 256K or 512K Level 2 cache, depending on the processor. The cache is not upgradeable.
- CPU Upgrade. This motherboard can accommodate the following CPUs:
- Pentium II 233, 266, 300, 333, 350, 400, 450 MHz with MMX technology.
- Pentium II/Celeron 266, 300, 333, 366 MHz with MMX technology (66MHz Host Bus frequency).
- Pentium II/Pentium III 400, 450, 500 MHz
- Single Edge Contact (SEC) cartridge. Uses the SLOT1 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 SDRAM DIMMs Supports only non-parity DIMM modules. The 168-pin DIMM sockets will support PC66/PC100 unbuffered 3.3V 1MBx64 (8MB), 2MBx64 (16MB), 4MBx64 (32MB), and 8MBx64 (64MB) and 16MBx64 (128MB) SDRAM DIMMs. PC100-compliant (100MHz) DIMMS should be used with any processor operating at 350MHz or faster. 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).
