 I believe every time your replace a RAM stick, you need to zap the  
 PRAM.

No you don't.

That's good to know.

Nevertheless, doesn't that force a RAM Check at Startup in PPCs if  
you do?

 Yanked the stick, put old one back in, Mac worked fine for several

 In two minutes, Firefox crashed yet again.

 D/l and ran Applejack Memtest, it said FAILURE many times, but I
 can't find the Applejack.log. Would like to read the specifics. Where
 is it?

 Also found ye olde Apple Hardware Test and that said Error Code mem_/
 2/4.

 Did not do the Qtip with Isopropyl Alcohol yet (what is this, a
 Ninendo64?) but if you guys think I should do it, okay.

 Somehow I think it is contacting all right, or the Tests would have
 remarked absence, but what do I know.

 Is it time to contact OWC for a replacement or is there something
 else to do? Oh, right, look in System logs.

 But are the two failures in the memory hardware tests definitive?

 Thanks and Happy New Year,

IMO, If you replaced the suspected bad stick, with one that works for  
awhile (in the same RAM slot  tested with Memtest), then put the  
suspected bad one back in the same RAM slot, and Memtest fails, I'd  
say it was a bad stick.

OWC might test it again ... but get them to replace it, as long as  
you have its serial number, you're good for replacement, AFAIK.

Hey, there - I didn't test the good old 256 stick yet - just the suspect
512. It seems better at the moment, no crashes yet (about 15 mins
and several programs open).

Sometimes fooling around with things gets them to work.

I'll check out the PRAM. I thought the PPCs didn't need to do that
anymore, that was just the older machines. Guess I stand
corrected.

The PRAM point appears debatable (and my personal experience shows no  
need in a Macbook but that's not this list):

There's a lot less stored in PRAM in OS X:

http://support.apple.com/kb/HT1242

The old Apple support document lists virtual RAM and RAM disk and disk  
cache and 32-bit addressing as being stored in PRAM which hints at the  
connection to newly installed RAM but the connection to the hardware  
itself is not clearly stated:

 What you do need to do when changing memory is push the button to

Could also just remove battery for a few minutes (Apple suggested 10).

Hi Anne:

I would call OWC, describe what you've done, run through any  
additional protocol they may have, and they will likely exchange with  
little or no quibble.

That would be enough for me to conclude it is the stick.
