Quicksilver 2002 1GHz DP - problems with replacement of dual processor card
About 9 months ago my QS2002 seemed to be running slower & would quit DVD player if I tried to start it in full screen; it would play broken green lines before doing so - although it seemed to be OK if I started in small view & switched to full screen once it had got going. Eye TV would randomly freeze too. Diagnostics said it had failed - the external cache was the problem. In "About this Mac" the 2MB L3 cache wasn't showing up. I spoke to a few people & they all thought it pointed to 1 of the processors failing on the daughter card so I kept an eye on eBay to try & get a replacement- which I did a few weeks ago.
I followed Sonnets instructions on how to change the processor card but on start up it only started for long enough to see that it had failed diagnostics with the same message as previously. It then had a kernel panic & refused to restart - either not progressing past the apple sign with a frozen cog or freezing if it got as far as OSX. I took out the replacement card & put the original one back. It booted without problem & was now registering the L3 cache & had passed the diagnostics test. I don't really understand why or how this was possible - did the card just need reseating?
The seller was very helpful & sent another card. - this time it had a kernel panic as it started & brought up something resembling the command page in Windows saying that there was a graphic chip error.
At this point I gave up, replaced the original card - which is still booting & passing diagnostics.
So are all replacement QS2002 1GHz DP cards not the same - any ideas why neither of these worked (the labels on them were very similar to the original)? Would I have similar problems if I tried an upgrade Sonnet or Newertech card? Did I miss something when changing the cards over & why did taking a card out and replacing it fix its external cache problem?
