Purpose-built upgrade for the Roland Fantom-Xr

This 512 MB DIMM is designed specifically for the Roland Fantom-Xr keyboard workstation. It delivers the exact memory specification that the instrument requires, allowing owners to reach the device's maximum supported capacity with a single module.

Direct 168-pin DIMM installation

The stick plugs straight into the keyboard's sole memory slot using the standard 168-pin interface. Unbuffered, non-ECC operation at 3.3 V means no additional configuration or supporting components are needed; the module simply frees the internal slot for the full 512 MB expansion.

Steady 133 MHz operation under continuous playback

Rated at PC133 with CL3 3-3-3 timings, the memory maintains consistent bandwidth during long sequencing sessions and sample-heavy patches. Major-brand chips and the unbuffered design keep latency predictable, so the workstation sustains performance without throttling during extended use.

Questions about this item

Will the 512 MB capacity limit the Roland Fantom-Xr when loading large sample sets?

The module provides 512 MB and the keyboard supports a maximum of one such stick, so total memory is capped at 512 MB.

Does the stick run hot or draw extra power during extended studio sessions?

It operates at 3.3 V without a heat spreader and is unbuffered, so power draw and heat stay low.

My Fantom-Xr currently has no RAM installed — is this 168-pin DIMM the only part I need?

Yes, the keyboard has a single 168-pin slot and this kit includes one compatible stick.
