This system has got 16KB Internal Cache (integrated into the CPU). The Cache memory on this motherboard CANNOT be upgraded.
This motherboard can accommodate the Intel Pentium P75, P90, P100, P120 and P133MHz, and the 150, 166, 180 and 200MHz Intel Pentium Overdrive Processor with MMX technology.
The upgrade processor installs in the Zero Insertion Force (ZIF) Socket. (U11H1). In the table below you can find the correct jumper settings for each processor:
| Speed | 8 | 6 | 7 | 2 |
|---|---|---|---|---|
| 75MHZ | OFF | OFF | OFF | OFF |
| 90MHZ | OFF | OFF | ON | OFF |
| 100MHZ | ON | OFF | OFF | ON |
| 120MHZ | OFF | ON | ON | ON |
| 133MHZ | ON | ON | OFF | ON |
| MMX 150 Overdrive* | OFF | ON | OFF | ON |
| MMX 166 Overdrive* | ON | OFF | OFF | ON |
| MMX 180 Overdrive* | OFF | ON | ON | ON |
| MMX 200 Overdrive* | ON | OFF | ON | ON |
* The Intel Pentium Overdrive Processor with MMX technology, is equipped with an on-package voltage regulator, which adapts the 3.3V system voltage to 2.8V processor voltage.
If you wish to install an MMX Overdrive processor, it may be necessary to have BIOS version 1.00.07 BY0R and at least 16MB of RAM installed. The current BIOS version will appear on the screen immediately after switching on the computer.
The video memory on this system can be upgraded to 2MB, by using two 256Kx16-70ns SOJ DRAM chips.
