Well,
- Purchase some fast PC4000 and PC4500 DDRSDRAM.
- AMD K8's FSB is at 1600 Mhz and it didn’t quite stop those 3DMarks2001/2003 point scorers in over clocking it (e.g. multiplier locked ‘Athlon 64’). Apple’s FSB is at 1000Mhz* as I recall. Both are Hypertransport based technologies as I recall.
- In over clocking the .13 micron Athlon XPs (T-Bred/Barton) (i.e. beyond 2.4 Ghz), some of extra cooling was applied for motherboard’s power regulators and Northbridge.
- purchasing a good power brick with plenty of Amps output on 3.3 volt rail (ATX).
- Purchasing of liquid cooled heat sink solution. A Dry Ice/Heat Pipe/LN2 could also work.
*Effective.
I don’t know IF Apple’s hyper transport has the ability lock down AGP and PCI speeds. This factor is critical for the hard disk. Principles from overclocking X86 processors maybe applied for the said PPC systems. |
