I am attempting to install a memory module from Crucial that NewEgg.com says should work. The Crucial Part# CT64M64S4D75, PC133, 512MB memory module. Unfortunately, the Mac G4 will not recognize the module, even when tried alone and in each of the slots. Listed below is the output TattleTech:

• Memory :

incompatible number of column address bits
This DIMM has problems that DIMM First Aid can't fix.

One or more DIMMs are not compatible


Would anyone be able to help diagnose? Is it the wrong kind of memory or a bad module? For reference the system is a G4 400MHz AGP Model

Thanks,

Well, based on the outputs, it would seem to me that there's some problem with the way the RAM is talking to your system. It's probably notewothy that TattleTech thinks that there's no actual RAM available on the stick, and that DIMM First Aid says there's a bad column address bit.

You might want to send it back to Crucial, or call their customer support and tell them what the output says. To me, it sounds like a hardware problem with that DIMM.
 
i couldnt be arsed to read that but i had a problem with crucial memory in my ibook i rang them and they said it was a problem with there chips rev 1 or something got a new 512mb so dimm and 100%

8:40 up 10 days, 11:47, 2 users, load averages: 0.33 0.61 0.81

Thanks for everyone's help. I purchased the item on Ebay so I am going to see if I can get it replaced. I apologize for inserting the email twice, makes it look a bit confusing. I will let you know what I find out, but I suspect some bad RAM.

Thanks,
