Firstly, these instructions are used on the complete understanding that I will not be held liable or responsible for any damaged caused or loss of data which may occur as a result of removing the potective plate covering the memory chip slots and that it' understood that these instructions are for guidance only. If in doubt, don't attempt to remove the protective plate.
There are two slots for extra memory chips, referred to in the documentation as DIMM's.
Should you need to insert extra memory, refer to the manual or your dealer to ensure you buy the right kind, it matters.
Yamaha recommends that you purchase DIMM's that conform to the JEDEC* standard.
Use only 168-pin DIMM's of 64, 128, 256 or 512 MB capacity (synchronized DRAM (SDRAM); PC100 or PC133).
Use only DIMM's that have a height 38.2 mm or less.
When installing DIMM's, 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 empty. Also make sure each DIMM in the pair is of the same manufacturer and the same type. DIMM's of different makers and configurations may not work together.
When purchasing DIMM's, make sure that the DIMM design does not utilize more than 18 memory chips per module. (DIMM's comprised of more than 18 chips do not operate correctly on the Tyros3.)
Before beginning the installation of memory chips, I'd strongly advise you read the section on this subject in the Tyros 3 owners manual so that you are aware of the do's and dont's of the task you are about to undertake.
Hint: The issue of losing one of the screws that holds the metal plate, which covers the DIMM slots should be given particular attention, as once a screw is dropped inside the instrument, there's an extremely height chance that you won't be able to retrieve it.
To avoid this, I left my T3 on its stand and removed the four screws from underneath, so that if I lost one, the only place it could fall is on the floor.
I then turned the instrument upside down to fit the memory chips, then turned it right side up and replaced the four screws from underneath.
1. With the bottom of the instrument facing you, go to the centre of the entire surface area. Slightly to the right of centre. You will find a flat metal plate with 4 groups of 5 elongated ventilation slots running across the middle of it.
The centre of the plastic surround at the bottom edge of the plate, towards the back edge of the instrument where the connectors are located, should have a semi-circular resess in it that looks like it's for putting a fingertip in it.
2. This plate has 4 screws, one at each corner. Remove these four screws and using the semi-circular resess gently lift the plate out. Whatever you do, put the four screws well out of the way before removing the plate, if you drop one inside the instrument you're asking for trouble, looking at what's inside there you will need help to extract a screw before you even think of connecting it to the mains power again.
3. Having removed the plate you will feel two memory chip slots, just like those inside a PC. You fit the memory chips in exactly the same way having made sure you've bought the correct type, (see above for information about which DIMM's to use).
Hint: The chip has a slit cut in the bottom edge of it. This is the edge of the chip that should be inserted into the slot in the T3.
Note: When inserting the chips, be aware that they will only go in one way round. Whatever you do, don't use excessive force when pushing the chips down into the slot.
When the chips are in correctly the plastic levers at either end of it should be in the upright position and clip into place against the end of the memory chip to hold it in place.
4. When the chips are in place, put the plate back over the opening then put the screws back in.
Job done!
