Quicksilver Memory Incompatibilities?
There was a post to xlr8yourmac.com late last week by a user who had recently received a Quicksilver G4 and had three 256MB PC133 CL2 (2-2-2) DIMMs, each containing 16 memory chips, to install. He encountered a memory error on boot (3 beeps) and found that if he took any one of the DIMMs out of the machine, even replacing it with the bundled Apple 128MB DIMM (comprised of 8 memory chips), all was fine. We have seen no other reports of problems with 3x 256MB (16 chip/ea) CL2 memory, but just today MacNN user vaporgirl posted this to the message thread on MacNN forums:
i ordered the 256 CL2 from OWC and had a very odd experience. installed it in the 2nd slot and my qs 867 sounded 3 tones and failed to boot - installed it in the 3rd slot and all was fine. tested the second slot by moving the preinstalled 128 DIMM there and it was fine. anyway i'm returning the 256 CL2 and upgrading to the 512 CL3 in the process.
...which is concerning. I have three 256MB PC133 CL2 DIMMs with 16 chips each on-hand, waiting to install in my dual-800 when it arrives. I hope there's no need to return any of this memory.
Is anyone seeing these sorts of issues with your new Quicksilver G4's?
UPDATE: According to a follow up article on xlr8yourmac, it's pretty much random luck that determines your success with various memory configurations... (Here's the now-available original story link from the site.)
