Are you discussing the "iMac DV (Slot Loading)" in your profile. If so, that's the identifier for a G3 iMac and I've never seen any specs anywhere stating that it can use 1G RAM modules in that model. Even the RAM sites that always tell you when a Mac can take more RAM than the original specs say the G3 slot-loaders are limited to 2 x 512MB modules.
The symptoms you describe certainly fit the issue of the G3 memory controller not recognizing 1G modules.
Good morning Allan,
Indeed, I suspect the RAM modules too.
Other threads have mentioned the PowerPCs not always working great with Kingston ValueRAM...
I went to the Kingston site and entered in the serials for one of them and there is a strong possibility they are counterfeit to boot. I live in China and this kind of thing is not that uncommon here.
If PowerPCs can be RAM finicky... well... it probably likes FAKE ValueRAM even LESS than the real thing.
Darn good job though - it looks more authentic than the working 512mb stick I am trying to replace.
Live and learn. When in the US I usually get bites and pieces from OWC. I miss it.
Thanks for your time and suggestions.
I've gotten all my Mac RAM from either OWC or Data Memory Systems for over a decade--good stuff.

The counterfeit thing never occurred to me. It's really getting out of hand. You can't order from OWC while in China?
