Below is a list of the hard disk drives that are compatible with the Tyros2:

Notes:
The Hard Disks listed above were confirmed to operate properly with Tyros2 through our lab tests. The tests were conducted on drives Yamaha obtained from the market. Keep in mind that all drives even of the same manufacturer and of the same model number may not always work properly with the instrument, due to subtle differences in manufacturing. For specific instructions on installation, refer to the relevant section in the owner's manual.

Below is a list of the DIMM memory modules that are compatible with the Tyros2:

Notes:

• Yamaha recommends that you purchase DIMMs that conform to the JEDEC* standard. Please be aware, however, that conformance to this standard does not constitute a guarantee that the DIMMs will operate correctly on the Tyros2.
  *JEDEC (Joint Electron Device Engineering Council) sets standards for terminal configurations within electronic devices.
• Use only 168-pin DIMMs of 64, 128, 256 or 512 MB capacity (synchronized DRAM; PC100 or PC133).
• Use only DIMMs that have a height 38.2 mm or less.
• When installing DIMMs, make sure to install them in a matched pair of the same capacity. You cannot install only one module and leave the second memory socket open. Also make sure each DIMM in the pair is of the same manufacturer and the same type. DIMMs of different makers and configurations may not work together.
• When purchasing DIMMs, make sure that the DIMM design does not utilize more than 18 memory chips per module. (DIMMs comprised of more than 18 chips do not operate correctly on the Tyros2.)
