PARIS, FRANCE–September 12, 2006–APPLE EXPO–Sonnet Technologies, a
leader in upgrades for Apple Macintosh computers and iPod digital
music players, announces a new line of dual processor upgrade
cards–the Encore/MDX G4 Duet 1.6 GHz and 1.8 GHz–the first
high-speed processor cards for Apple’s popular Power Mac G4 MDD
(Mirrored Drive Door) and Xserve G4.

The Encore/MDX G4 Duet comes complete for installation into either
tower or server. The original MDDs and G4 XServes were shipped in
2003 and 2004 in single and dual cpu configurations starting at 867
MHz and 1GHz, respectively. States Robert Farnsworth, Sonnet CEO,
“Like all of our cpu upgrades, the Encore/MDX is a simple and
economical speed bump for someone invested in a hardware and software
configuration. Upgrading a single 1GHz to a dual 1.8 GHz can yield
significant performance improvements.”

Encore/MDX G4 Duet upgrades are based on the Freescale Semiconductor
(formerly a division of Motorola) PowerPCG4 7447A processors,
featuring 512K of SRAM on-chip L2 cache per processor. They are
compatible with Mac OS 9.2, and Mac OS X Version 10.3.5 and higher.
Each upgrade includes a factory-attached heat sink, fan, and mounting
bracket for either MDD or Xserve installation.
