ATIccelerator II comes with ABSOLUTELY NO WARRANTY. If you destroy your costly 9800 Pro or your now worthless Rage 128 because of a bug in this program or your careless utilisation of it, you're on your own!


ATIccelerator II can change ATI graphics cards frequencies live, on-the-fly, under Mac OS X. It's much more sophisticated and convenient to use than
Graphiccelerator for the following reasons:

* no potentially dangerous flashing required
* no cumbersome three-steps process (dump, modify, then reflash ROM)
* no need to reboot for every frequency change
* no OS 9 required (that's right, G5s and other recent OS 9-free Macs are now supported!)

Graphics cards overclocking on the Mac finally comes out of stone age!

(The Radeon X1600, X1900 and later cards aren't supported yet.)
