Hi, I have a J700, and I have installed OS 10.2 on it. Generally, everything seems to be running fine, except that my system quite frequently freezes (It usually happens within the first hour after I boot the machine). Running multiple apps seems to make the problem worse, but I haven't been able to isolate the problem to any particular application or action on my part. Sometimes, the freeze happens during the blue screen boot sequence.
My J700 has a Radeon 7000 Mac Edition video card in slot A, a Tempo Trio card in slot B, a Sonnet Crescendo G4 800 Mhz processor card, and 4 128 Mb DIMMs in memory slots B1 - B4. OS 10.2 lives on a 7.99 Mb partition on a 60 Gb Maxtor ATA hard drive that's attached to the Tempo Trio card. The system also has an Apple-compatible CD-ROM drive, and one 4 Mb SCSI drive that contains OS 9.1. There are no Firewire or USB devices connected to the Temo Trio card. I've tried pulling the Temo Trio card and installing OS 10.2 to a spare SCSI drive, but I still had the freezes. I've also tried using the original video card, but the freezes continued. I've also tried disconnecting the SCSI cable from the motherboard (thinking that I might have a SCSI termination problem), but that didn't help, either. So I'm thinking that I probably have a memory problem (by the way, the system works perfectly fine when running OS 9.1). My memory is OWC branded (bought from Other World Computing). I've tried running the system with one DIMM installed at a time, but I was able to get the system to freeze with any single DIMM installed in slot A4. I've heard from some people that if I buy better quality memory that the problem might go away. Ramjet's site (and one of their reps) recommends using only 2K refresh memory on systems with processor accelerator cards, but that means that I can't use 128 Mb DIMMs. Any suggestions would be appreciated. I don't mind spending the money on better memory, if that's what's needed, but I don't want to keep buying things that may not work.
