Greetings. I recently purchased a PowerLogix G4/550 processor upgrade for my Yikes tower. I was told that these can be upclocked, which I successfully did. I later discovered that the backside cache ratio was specified at 2.5:1 with a max of 220 mhz; however, the cache control allows you to set this at 2:1, which would give you a 300 mhz cache speed with a 600 mhz processor speed. However, I couldn't confirm that setting with the cache control and I wonder if it changed beyond 220 mhz. Can any of you with experience with processor upgrades tell me if cache settings can also be upclocked? Thanks.
