Roland Fantom-G compatible upgrade

This 1GB PC133 SDRAM DIMM is built specifically for the Roland Fantom-G6, Fantom-G7 and Fantom G8 keyboards. It fits the single 168-pin slot and matches the factory voltage of 3.3V so the instrument recognises the module immediately. Musicians restoring or expanding a Fantom-G workstation can install it without configuration changes.

Low-voltage unbuffered operation

Running at 133 MHz with CL3 3-3-3 timings, the stick draws minimal current from the keyboard’s internal supply. No heat spreader is fitted and the unbuffered design adds no active components, so the module stays cool and silent inside the sealed chassis. Normal playing sessions produce no audible noise or thermal throttling.

Steady sustained performance

The Major Brand Chipset and 2Rx8 organisation deliver consistent bandwidth during long sampling or sequencing sessions. Because the Fantom-G only accepts one module, the full 1GB capacity is always available and there is no interleaving delay. The memory maintains rated speed continuously without downclocking.

Questions about this item

How do I install the 168-pin DIMM in my Roland Fantom-G keyboard, and what step is most often missed?

Power off the keyboard, open the memory compartment, align the notches on the 168-pin DIMM with the slot key, press firmly until both side clips click, then verify the module is seated evenly before closing the cover.

What maintenance or replacement will the CM12864133DIMM need over time?

The unbuffered non-ECC SDRAM has no moving parts or batteries; keep the slot contacts clean and reseat the stick if the keyboard fails to recognise the 1GB capacity after transport or vibration.

What limit appears first when the Roland Fantom-G runs sustained workloads with this PC133 module?

The single 168-pin socket caps total memory at 1GB, so the capacity ceiling is reached before the 133 MHz speed or 3.3 V supply becomes a bottleneck.
