ibook doesn't detect expanded memory

[Juice]

I just bought 2 kingston ddr 266 or PC2100 sodimms from Villman. I installed them on 2 ibooks and both ibooks didn't detect them. I installed them properly and checked several times. So what gives? Any suggestions?

[Maverick]

out of curiosity... how much ram was in the ibook prior to installation... and how much ram did you just install?

[Juice]

The built in memory is 256 and the expanded memory installed is 128

just checked kingston's site.... they don't seem to have a 128 mb chip...

Juice,

there have been issues before about certain types of RAM modules not working with Mac portables. We've encountered this issue a few times with Powerbooks. This incident could be similar to that.

It's also possible that the RAM module just isn't seated properly.

If all else fails, just return the RAM, ask for a refund and buy from another vendor.

jofab, that's what I plan to do on Monday. Thanks for the replies.
