PC133 DIMM for Roland MC-909

This 512MB SDRAM module uses a 168-pin DIMM form factor and runs at 133 MHz with CL3 timing. It is unbuffered, non-ECC memory built with major-brand chips and operates at 3.3V. The stick is designed specifically for the Roland MC-909 Sampling Groovebox keyboard.

Replaces the factory 256MB limit

The MC-909 ships with a single socket supporting one module, so this 512MB stick doubles the original capacity in one step. The upgrade is worth it when projects exceed the stock memory and the sampler begins to truncate samples or refuse new loads.

Single-slot installation, no spreader

The module fits the sole DIMM slot inside the groovebox and requires no additional cooling or power changes. It frees the internal memory ceiling for larger sample sets while leaving all other expansion bays untouched.

Questions about this item

Will the 168-pin DIMM fit the single memory socket in the Roland MC-909?

Yes, the module is a 168-pin DIMM and the MC-909 has one compatible socket, so it fits directly.

What is the correct way to seat the 168-pin DIMM in the MC-909, and what step do people often miss?

Align the notches on the module with the socket keys, press firmly until both retaining clips click shut; the step often missed is verifying both clips are fully engaged.

How long will this PC133 SDRAM last before it needs replacement in the MC-909?

SDRAM has no moving parts and typically runs for the life of the instrument; replacement is only needed if a fault develops.
