Default Mac not registering memory right.

I bought 4 256mb PC133 Latency 3 sticks and put them in my mac. They are only registering as 128mb each and it is crashing. Thing of it is, is that I know that it is the right memory. Possibly labled wrong?

Are the ram sticks single or doublesided?
often doubsided memory is supported only partially such as if you put it in slots 0,1
then you have to leave slots 3 & 4 empty, or something like that.

Are you sure your mac supports memory sticks above 128M?

which mac do you have?

It is a Blue and white G3 400MHz Yosemite. The memory is single sided, high density. Yes it does support up to 512 on a single stick. I have the 4 256mb.

Answer: The Power Macintosh G3 (Blue and White) has four DIMM slots that can accommodate up to 256MB DIMMs each, for a total of 1,024MB (1 gigabyte) of memory. When using 256MB DIMMs, use 128Mbit-device technology, not 64Mbit or 256Mbit. The 256MB DIMMs are available from the Apple Store.
