Grackle Probe X
1.4
Grackle Probe X
1.4Enable Quartz Extreme for AGP & PCI-based Macs.
Overview
Grackle Probe accelerates Grackle based Macs that are using the Quartz Extreme PCI hack that's been mentioned recently. Grackle Probe could accelerate Grackle based Macs that have high-performance PCI cards, without needing to use the Quartz Extreme PCI hack or any undesirable side effects that QE has. It is not known what the compatibility or the side effects of enabling PCI Store Gathering is.
What's new in Grackle Probe X
Version 1.4 adds the following:
- Version 1.4 is more reliable on OS X 10.2.0 now due to switching back to the GCC 3.1 compiler.
- Changed GrackleProbe so it is suitable for dropping into /Library/StartupItems.
- Now comes with grackletool. When GrackleProbe is loaded, executing grackletool will display a bunch of information about the Grackle chip.
- Grackletool will display the SDRAM CAS settings the Grackle memoryx controller is configured for. If you have CL 3 RAM, the SDRAM CAS setting is like 3. If you have CL 2 RAM, the CAS setting might or might not be 2. The firmware calculates this really early at startup.
- There may or may not be an incompatibility with the ACARD 6820 IDE PCI card. Two people with this card have reported a panic. I'm looking into this.
