From François
I just wanted to say I met exactly the same problem with a G4 iMac I'd just bought. The extra 512Mo memory upgrade I had were cause to the same problem described by Thierry (screen off as if the video card was down and OS X install couldn't go on after the 1st CD). Once it had been replaced all symptoms were gone. But the customer service had to take this brand new iMac three times before they could get what was going on ! |
From Teo
I bought from a mate who'd got it eleven months before his Ti 400, under OS9, in January 2002 (RAM 256+128): RAM was instable according to the one I chose to put first. Eventually kept the 256 only, though Dimm First Aid certifies it's OK. Sept. 2003: upgrading to Jaquar, no pb with my 256. Jan. 2003, add 512 Mo RAM, no pb Feb. 2003: X.2.4 upd: KP repeteadly, session log out followed by Blue screen, applications crashing all the time, two clean install processes later, the pb is not solved. Testing my RAM under OS 9 again with Dimm First Aid: no pb, no crash under OS 9. A new test without 256 under 9 & X : no pb. Without this 256 Mo no pb any more for 3 months. Jaguar seems to tolerate better some older memory upgrades, which came from a "certified" place though... |
