I got two 2x 256 sticks for my 1.8 today from Crucial (ordering the supposed special G5 matched pairs).
Checked the about this Mac dialogue box and sore the full amount of Ram was recognised.
Had one or two kernel panics through the day (my very first on this machine) which I thought was odd...
Later played a game of Sof2, now I've been having problems with the audio speed/quality in this game recently after changing the s_hunkmeg size, solved it by going back to the default size, BUT when I started up sof2 after I had installed the Ram, sound distortion was back big time, and a chirping beeping noise (like one of the in game sound effects being constantly echoed and magnified) kept looping, getting louder and louder and louder.
After quitting the game this sound remained,
After trying to troubleshoot sof2 (as I thought this was the prob again) I noticed audio in iTunes was distorted, had a kernel panic, and pulled the ram.
I tried the Crucial ram in different matching slots/banks, same problem.
I tried the Crucial ram on it's own (1st available slots, where the Apple Ram comes installed), and everything's fine.
So I installed the Apple ram in the slots I originally installed the crucial Ram in, everything's peachy.
Now I could only guess at this point that the Ram in the 1st pair of slots controls what spec or maybe even speed (say PC2700) all the rest of the ram in your system has to live up to.
After running the extended Hardware test CD, one of the Crucial Ram sticks failed.
The lady at crucial hardly believed me, she said they NEVER had a failed Ram stick for a 1.8 or Dual 2Gig, ever, mine was/is the very first and they will be thoroughly testing it to see what's wrong!

and then of course you will report back to us with some details and tell us about the free gig they give you for being the first with bad ram (just a thought of course).

I doubt it somehow, considering how they sounded like they were doing me a favour exchanging my Ram, it'b be nice though!

Getting a kernel panic loading a save game in JK2, (v latest patch) never had this prob before.
This is since I've swapped the slots the Crucial ram is in, which i did so I could run AHT to see if the reported bad stick changed slots (to check if it's a Ram or slot issue) it did.

I had a 512 chip from them fail the hardware test in my 1.8 G5 and they replaced it no questions asked, even though I don't think it even caused any kernal panics or any weird. She must not have known.

Sounds like your motherboard has a VERY fishy memory controller.

Okay aftre taking out my crucial ram (to return it) I've realised that the two sticks that I swapped positions last, were not the crucials, but the apple memory, this is getting stranger and stranger.
Just about to running the extended AHT now just on the original ram, alhtough I'm sure I ran it before and it was fine
