my friend's father bought his old imac (350 Mhz slot loading w/ 100 Mhz system bus) 512 MB of ram ( two 256 MB dimms). But, he bought PC133 ram and insists taht he was told it was the right memory. I said it qont, but he wants to be sure. Is PC133 ram backwards compatable w/ a PC100 system?

The exact spec on the package are: Simpletech
256 MB PC133 168 pin unbuffered non-ecc sd ram dimm memory module

Please answer quickly!

Faster memory is an improvement over marginal memory at the slowest speed you can use.

Some macs required PC133 on the 100MHz bus.

I have used a PC133 module in my Blue and White G3 and it's fine with it.
