Sonnet Steps Up Speed, Pushes Down Processor Upgrade Prices

IRVINE, CALIFORNIA—August 1, 2005—Sonnet Technologies, a worldwide leader in upgrades for Apple ® computers and iPod® digital music players, announces two new top of the line single processor Encore™/ST processor upgrades—the Encore/ST G4 1.8 GHz (Part No. SG4-1800) for most “Sawtooth” Power Mac® G4 systems, including AGP Graphics, Gigabit , Digital Audio and QuickSilver models, and the Encore/ST G4 1.8 GHz (Part No. SG4-C1800) made specifically for the Cube. These products represent a new high point in performance and value in Sonnet’s most popular line of processor upgrades; each one is priced $50 less than the 1.7 GHz upgrade it replaces.

These cards, based on the latest and fastest PowerPC™ G4 processor (used in Apple’s current PowerBook® line) from Freescale Semiconductor, feature 512K of SRAM on-chip L2 cache and are compatible with Mac OS® 9.2, and Mac OS X Version 10.3.5 and higher. All Encore/ST G4 upgrades for Power Mac G4 tower computers include a factory-attached heat sink that fits seamlessly into all supported systems. The Encore/ST G4 1.8 GHz upgrade for Power Mac G4 Cube includes a quiet fan plus all required hardware, tools and detailed installation instructions (professional installation is recommended). Like all Sonnet processor upgrades, both new Encore/ST G4 models carry a three-year warranty.
