Adding Cache Memory - Mitsubishi Electric Apricot VS Owner's Handbook Manual

Adding more cache memory
An external or secondary level (L2) cache is a small amount of
specialised memory with significantly faster access times than the
computer's system RAM. A controller ensures that it always contains
a copy of the most recently accessed areas of RAM, so that the
processor is able to read it quickly, without waiting for the slower
main memory.
In this system, only the first 64 Mb of RAM is cached.
First-level (L1) cache is contained within the processor itself, and is
not changeable. It could be either 8 Kb or 16 Kb.
You can improve the performance of some software applications by
adding or upgrading the L2 cache memory.
To decide if an upgrade is possible:
• Check the BIOS summary page, to find out how much cache
• Check with your supplier to find out what upgrade kits are
Caution
Some older software is very speed sensitive and in some cases, to use it, you may
have to disable the cache memory.
To fit cache memory
1. Turn off the computer and unplug all power cords.
2. Take suitable anti-static precautions and remove the system unit
Caution
If you are unfamiliar with the recommended anti-static precautions and/or the
process of removing the system unit cover, refer to Appendix A, "The System
Unit".
