Upgrades

Cache Upgrade. The 980 motherboard comes with 0 or 512K Level 2 cache. The cache is not upgradeable.
CPU Upgrade. Zero Insertion Force (ZIF) socket. Uses the 321-pin Type 7 CPU Socket. Not keyboard switchable. Disable cache to slow down the system.This motherboard can accommodate the following CPUs:
- Pentium P55C 166 - 233MHz
- Cyrix 6x86L, PR120+ - 200+
- Cyrix 6x86MX, PR133 - PR350
- Cyrix 6x86 MII 266 - 350
- AMD-K5/K6/K6-2/K6-3 166 - 400MHz
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. 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. 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).

Issues

Installing A Third Party Video Card

There is a jumper on the motherboard, located near the DIMM sockets. This jumper is labelled JP1 and has the words Open Default and Closed Disable VGA. This will disable the onboard video when the 2 pins of the jumper are covered.

Portions Of The Display Are Blocky When Playing 3D Games

There is no resolution to this situation. This is a hardware limitation.
