| Will my Crescendo/WS upgrade recognize any DIMM? | May-12-09 |
| The Crescendo/WS will work with any DIMM that works with the "stock" Wall Street PowerBook, and in many cases increases available memory from 192MB to 512MB. This is due to the resolution of an Apple ROM issue that prevented some of these systems from properly recognizing all available RAM.
There are some 256MB modules that can only be utilized as 128MB, due to a limitation of the parts used at the time that these notebooks were manufactured. A controller chip used in the system's design can recognize a maximum of 128MB of RAM in each "bank" of memory. Until recently, virtually alll 256MB DIMMs used two banks of 128MB. Recent advances in RAM have led to the introduction of some DIMMs with 256MB in a single bank, which has raised the visibility of this issue. These parts are stable, and are not known to reduce system reliability, but they will not deliver the full desired memory capacity. There is no single method for identifying these parts without installing them, so it is recommended that you work with a reseller who can either confirm the design, or who will accept a return based on compatibility. |

| PowerBook crashes when Sonnet Crescendo/Encore software extension is active. | May-12-09 |
| The only function of the Sonnet extension is to activate the caches on the upgrade. So if enabling this software causes a crash and disabling it makes the crashing go away, it's a sign that the cache on the card is bad. There is no solution for this problem as this product is obsolete and out of warranty. |
