can you use 667mhz ddr2 in a early 2008 iMac

[Anarchy99]

Hello,
Just out of curiosity, I know everyone recommends against using ram the other way (putting in 800 MHz into a 667 MHz machine) but what about the other way around?
If I have an early 2008 iMac 8,1 that normally uses 800 MHz RAM
other than a minor performance hit would 667 MHz RAM work?
If so what's the best utility to test whether it's stable or not?


thanks

It won't boot. The iMac will beep out an error code for bad or no memory. There's nothing wrong with putting faster memory in a slower computer. Some machines don't like it, but most Macs don't mind. However, slower memory in a faster computer is generally frowned upon as it rarely works at all.
