1. Installing Optional Equipment
274 RS7000
You can increase the RS7000’s memory by installing commercially available SIMMs (single in-line memory modules). This section
explains how to carry out the installation.
Installing SIMMs
The RS7000 does not necessarily support all commercially available SIMMs. YAMAHA cannot guarantee opera-
tion of SIMMs that you purchase. Before purchasing SIMMs, please consult your YAMAHA dealer or an autho-
rized YAMAHA distributor (see list at end of the Owner’s Manual) for advice.

•Before beginning the installation, please read precautions “Handling and Installation of Options,” found at
the beginning of this manual.
•You need to use 72-pin SIMMs with access times of 70ns or less. The SIMM module size may be 4, 8, 16,
or 32 MB. The RS7000 is designed for use with 32 bit SIMMs, but can also accept installation of 36 bit
(parity-type) SIMMs.
•When purchasing SIMMs, make sure that the SIMM design does not utilize more than 18 memory chips
per module. (SIMMs comprised of more than 18 chips do not operate correctly on the RS7000.)
•SIMMs must be installed as a pair of the identical capacity. It is not possible to add just a single SIMM.
•The RS7000 ships with 4 MB of memory installed. This means that if, for example, you install a pair of 16
MB SIMMs, the sampling memory will be 4 + (16 × 2) = 36 MB. However, the maximum sampling memory
is 64 MB. For this reasons the original memory will effectively be disabled if you install a pair of 32 MB
SIMMs (one pair: 32 × 2 = 64 MB).
•YAMAHA recommends that you purchase SIMMs that conform to the JEDEC* standard.
Please be aware, however, that conformance to this standard does not guarantee that the SIMM will oper-
ate on the RS7000 even if it operates on a personal computer.
* JEDEC (Joint Electron Device Engineering Council) sets standards for terminal configurations within electronic
devices.
