Hey, ive got a Power Mac G4 400MHz with 384Mb RAM.

The RAM is 2 Sticks of 128Mb and 2 Sticks of 64Mb.

I had looked it put on the internet and checked the crucial website and i found that i needed a stick of 512Mb the was SDRAM PC133 168 Pin Non-ECC Un-buffered.

I baught this RAM installed it and it is saying that the slot that it istalled in is empty, ive tried it in the rest of the slots and all say there is nothing there, is there something i am doing wrong, and help would be appreciated. :D

Thanks

The RAM you bought is not compatible with Apple computer. If it was cheap, it's not the correct ram. I ordered 2 512MB sticks that I thought would work as well for like $20 shipped. But it needs to say it's compatible with Apple computers, otherwise it's probably not. One 512MB stick that works on Macs is usually around $30 on ebay if I remember correctly.

Did you buy high-density memory? Also you have a 100mhz bus but I'm pretty sure the 133mhz memory should automatically downclock to 100mhz so that shouldn't be a problem. I'd take that memory back.

I have 2 sticks of 128mb that you can have.

Have you tried using just that one stick of 512 RAM without any other sticks in there to see if it works by itself?

I've had some issues mixing PC100 and PC133 sticks in the G4s and especially when trying to use it with 64MB sticks. If it works by itself, add one stick of 128 at a time to see if it works as you add.

I have a 450MhZ G4 and just put in two additional sticks of this to match the two 512MB Kingston Apple PC100 sticks in there and it recognizes all 2GB.
