 INSTALLING THE OPTIONAL DIMMS
Compatible DIMMs
The Tyros3 does not necessarily support all commercially 
available DIMMs. Yamaha cannot guarantee operation of 
DIMMs that you purchase. Before purchasing DIMMs, see the 
following page:
http://music-tyros.com/
DIMM Type and DIMM Con guration
•  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 
Tyros3.
*  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 of 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 confi gurations 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 Tyros3.)
DIMM Installation
Before following the steps below, make sure you have 
WARNING
•  Before beginning installation, switch off the power to the Tyros3 and connected peripherals, and unplug them from the 
power outlet. Then remove all cables connecting the Tyros3 to other devices. (Leaving the power cord connected while 
working can result in electric shock. Leaving other cables connected can interfere with work.)
•  Be careful not to drop any screws inside the instrument during installation (this can be prevented by keeping the optional 
units and cover away from the instrument while attaching). If this does happen, be sure to remove the screw(s) from 
inside the unit before turning the power on. Loose screws inside the instrument can cause improper operation or serious 
damage. 
•  Install the optional units carefully as described in the procedure below. Improper installation can cause shorts which may 
result in irreparable damage and pose a fi re hazard.
CAUTION
•  Do not touch the exposed metal parts in the circuit board. Touching these parts may result in a faulty contact.
•  Be careful not to misplace any of the screws since all of them are used.
•  Be careful of static electricity. Static electricity discharge can damage the DIMMs or the instrument. Before you handle 
the DIMMs, to reduce the possibility of static electricity, touch some unpainted metal surface or a ground wire on a 
device that is grounded.
•  Do not use any screws other than what are installed on the instrument. Installing optional DIMMs to the Tyros3 allows you to save large amounts of Voice data created by the Voice Creator function. This sec-
tion explains how to install DIMM memory modules to the Tyros3.
appropriate DIMMs and a Phillips screwdriver.
1 Turn the Tyros3’s power off, and disconnect 
any cables including AC power cord from the 
keyboard.
  Also make sure to close the LCD panel and disconnect a 
USB device from the USB TO DEVICE terminal.
2 Turn the Tyros3 face down on a blanket or some 
soft surface, giving you direct access to the 
bottom of the instrument.

 REPLACING THE INTERNAL HARD DISK
Before following the steps below, make sure you have an ap-
propriate hard disk drive and a Phillips screwdriver.
1 Turn the Tyros3’s power off, disconnect any 
cables including AC power cord from the 
keyboard.
  Also make sure to close the LCD panel and disconnect a 
USB device from the USB TO DEVICE terminal.
2 Turn the Tyros3 face down on a blanket or some 
soft surface, giving you direct access to the 
bottom of the instrument.
WARNING
•  Before beginning, switch off the power to the Tyros3 and connected peripherals, and unplug them from the power outlet. 
Then remove all cables connecting the Tyros3 to other devices. (Leaving the power cord connected while working can 
result in electric shock. Leaving other cables connected can interfere with work.)
•  Be careful not to drop any screws inside the instrument. If this does happen, be sure to remove the screw(s) from inside 
the unit before turning the power on. Loose screws inside the instrument can cause improper operation or serious 
damage. If you are unable to retrieve a dropped screw, consult your Yamaha dealer for advice.
•  Install the hard disk units carefully as described in the procedure below. Improper installation can cause shorts which 
may result in irreparable damage and pose a fi re hazard.
•  Do not disassemble, modify, or apply excessive force to board areas and connectors on hard disk units. Bending or 
tampering with boards and connectors may lead to electric shock, fi re, or equipment failures.
CAUTION
•  Before removing the installed hard disk unit, make sure to backup any necessary data on the disk to computer by using 
the USB Storage Mode. This will prevent loss of important data and enable you to use the data on the new hard disk. (If 
you need to backup the recorded audio fi les, save the hidden folder “HDR.ROOT” to the computer.)
•  It is recommended that you wear gloves to protect your hands from metallic projections on hard disk units and other 
components. Touching leads or connectors with bare hands may cause fi nger cuts, and may also result in poor electrical 
contact or electrostatic damage.
•  Handle the hard disk unit with care. Dropping or subjecting them to any kind of shock may cause damage or result in a 
malfunction.
•  Be careful of static electricity. Static electricity discharge can damage the IC chips on the hard disk or the instrument. 
Before you handle the hard disk, to reduce the possibility of static electricity, touch the metal parts other than the painted 
area or a ground wire on the devices that are grounded.
•  Do not touch the exposed metal parts in the circuit board. Touching these parts may result in a faulty contact.
•  Be careful not to misplace any of the screws since all of them are used.
•  Do not use any screws other than what are installed on the instrument. If the factory-installed hard disk crashes or when you want to replace it with another one (for example, one you have used on the Tyros/
Tyros2), you can remove the current one and install the new one by following the procedure below. The hard disk used must be a 2.5-inch 
P-ATA (parallel ATA) compatible; however, not all such drives may be installable.
3 Remove the three screws.
4 Pull out the hard disk bracket.
NOTE
•  Hard disk drives thicker than 12.7 mm cannot be installed to the Tyros3.
•  S-ATA compatible hard disks cannot be used.

5 Remove the four screws to remove the installed 
hard disk unit from the bracket.
6 Attach the new hard disk unit to the bracket 
using the four screws removed in step 5.
7 Set the Tyros3 right-side up.
8 Insert the hard disk bracket into the slot.
NOTE
If you have installed the hard disk that was once used for the Tyros/Tyros2 and turn the Tyros3’s power on, you can 
immediately view the fi les on the hard disk and use the Song fi les from the Tyros/Tyros2. However, to properly use the Style, 
Multi Pad, and Registration Memory fi les from the Tyros/Tyros2, you will need to convert the data using a computer and the 
File Converter software (available for free download on the Tyros3 website).
You should tighten these two
screws first.
Make sure the bottom of the hard disk is facing up.
Depending on the type of hard disk drive you plan to 
install, select holesor holes
to attach the hard disk
drive.
* Holes  are used in this illustration.
9 Turn the Tyros3 face down again and fasten the 
three screws removed in step 3.
10 Check that the installed hard disk is functioning 
properly.
  Set the Tyros3 right-side up, and turn the power on. If the 
HD tab appears on the File Selection display, the hard 
disk is OK.
