PowerCenter & Sonnet G4/700 |

I recently upgraded a PowerCenter with a Sonnet G3/450, Sonnet Tango, ATI Radeon 7000 and an Adaptec 2930CU running 10.2.6 to a G4/700. The configuration has been unstable since. I have removed all PCI cards except the Radeon and it is still unstable. The system will boot but hangs often/randomly. Other times the system will freeze or show the kernal panic screen we all know and love. I cannot get disk first aid to complete a pass through repairing permissions. I am using XpostFacto 2.2.5 and Sonnet's latest cache enabler 1.2.7. Any ideas? Thanks |

Check the Sonnet website but I believe that it states that this upgrade (the G4/450) will not work with the PowerCenter board even though the 700 & 800 chips do. |

I have heard of the "L2 Cache Solution" with XLR8 chips, but this is the first confirmation that it possibly occurs with Sonnet chips. Question, if you reinstall the original cache chip, how does that affect the on-board cache on the processor card???? Can you still tweak with say Power Logic cache control utility??? |

I had the same problem when I moved from a G3/500 to an Xlr8 G4/450 Ziff on an SSE Carrier card last year. The problem turned out to be RAM related. What is your RAM configuration like, e.g. how much, what speed does it run at (60ns or 70ns), is it mixed between different speed parts, etc. I have a Power Tower Pro and the solution to my instability problem with the Xlr8 G4/450 was counterintuitive. Doing some research in the xlr8yourmac.com processor upgrade database I cam across a post where the user was having the same problem I had. I had been forced to deinterleave my RAM and substitute four 128MB sticks of 60ns OWC RAM with four sticks of 64MB 60ns RAM from my Power Center Pro. This arrangement worked but I lost the performance benefit of the wider memory bandwidth that results form memory interleaving in older systems that support it. The solution was to reinstall the original L2 cache. Once I did that I was able to reinstall the 4 sticks of 128MB RAM and reinterleave all 8 RAM slots for a total of 1GB of RAM. I upgraded again when the Sonnet G4/800's were released but no longer had instability problems due to RAM. I was also able to remove the L2 cache again. So, in that case the problem was unique to the Xlr8 G4/450. During the last two or 3 weeks there was a new posting from someone with a Sonnet G4/700 card experiencing the same problem. He found the same post, as well as mine, attesting to the effectiveness of the L2 cache fix and was able to resolve his instability issues the same way. Check it out. |
