• You need to use 72-pin SIMMs with access time of 70ns or less. The SIMM module
size may be 4MB, 8MB, 16MB, or 32MB. The A3000 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 A3000.)
• SIMMs must be installed in pairs: you can install either two SIMMs or four SIMMs.
Both modules in a pair must have the same memory capacity.
• The A3000 ships with 2MB of sampling memory installed, and is capable of accessing
up to 128MB. If you add one pair of 32MB SIMMs, for example, you increase the
available sampling memory to a total of (2 + 32 ´ 2
66MB. If you install four 32MB
SIMMs, however, the sampling memory size becomes 128MB (and the original 2MB
are effectively disabled).
Uit de manual van de A4000/A5000:
• Before performing 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 time of 70ns or less. The SIMM module size may be 4MB,
8MB, 16MB, or 32MB. The A5000/A4000 is designed for use with 32-bit (parity non-type) 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 A5000/
A4000.)
• SIMMs must be installed in pairs: you can install either two SIMMs or four SIMMs. Both modules in a
pair must have the same memory capacity.
• The A5000/A4000 ships with 4MB of sampling memory installed, and is capable of accessing up to
128MB. If you add one pair of 32MB SIMMs, for example, you increase the available sampling memory
to a total of (4 + 32 x 2
68MB. If you install four 32MB SIMMs, however, the sampling memory size
becomes 128MB (and the original 4MB are effectively disabled).
• Yamaha recommends that you purchase SIMMs that conform to the JEDEC* standard. Please be
aware, however, that conformance to this standard does not constitute a guarantee that the SIMMs will
operate correctly on the A5000/A4000.
* JEDEC (Joint Electron Device Engineering Council) sets standards for terminal configurations within electronic
devices.
