The PowerForce G4 1GHz has a 2 year limited warranty and 30-day MBG per the Powerlogix warranty page as of the review date. (Subject to the returns policy of the dealer.) See the Powerlogix PowerForce Series 133 page for more info. For 100MHz bus speed Macs (G4/AGP Sawtooth and Gigabit Ethernet towers and G4 Cube), see the Series 100 product page.

L3 Cache - SDR vs DDR:
Powerlogix uses 2MB of SDR L3 cache per CPU on this model. Sonnet uses DDR cache on their (single only) AGP CPU upgrades for Towers and Cubes. Powerlogix previously posted a white paper (PDF file) on DDR vs SDR L3 cache performance.

For owner reports on CPU upgrades (any brand/mac model), search my Rate Your CPU Upgrade database.

I stress that owners of any upgrade should use it for several weeks at least before posting an entry in my database. If there are problems - contact the vendor immediately, they often can provide a solution or identify the source of the problem.
