G4/400 "Sawtooth"

Long ago when the controversial RAM-disabling firmware upgrade came out I decided not to risk it and just went on using my computer and everything was cool all the way through 10.1.5. Unfortunately when I installed Jaguar I began having massive stability problems. I went through the whole gamut of disk checking and even a reformat and it was still a mess. Finally today under the advice of a friend I tried yanking out the 2 3rd-party DIMMs [I had 1 Apple 256 and 2 generic 256] I had installed and everything went back to normal [albeit much slower].

On to my question: What exactly is it that I'm looking for when replacing these? What makes them "Sawtooth compatible"? Sites like crucial want over $50/256 meg DIMM and that's a bit steep for me right now. Are there other cheaper [but still quality] alternatives? Can I use PC133? [no I'm not expecting a speed increase, it's just more common].

Sawtooth 350 here. 1.3 GB (512+512+256+64 all 222-speed)

I ordered 512MB and 256MB modules from here. There were no issues. If in doubt, look up Mac memory for your model on www.ramseeker.com

I also skipped the RAM-killer firmware. Still on the previous firmware, running 9.2.1 and 10.2.x without problems.

DEFINATELY update your firmware. X has no love for boxes without the latest and greatest.
as for your ram, update the firmware, throw it all back in, and see which ones aren't recognized (or if any keep it from working! ) if you got duds, buy some techworks from otherworldcomputing. competitavely priced and lifetime guarantee. i never had any problems with it. ever.

From what I remember, stores were exchanging any RAM that didn't meet the firmware's specs. I don't know if they'll still do that, but since most RAM has a lifetime warranty, you should ask 'em about it.
