Which PC100 SDRAM is compatible with iMac?

Which PC100 SDRAM is compatible with iMac?

I've recently acquired an aging iMac (G3/500 DV SE, Summer 2000) with its original 128Mb RAM out of a possible 1Gb. I'd like to replace the single 128Mb DIMM with 2 x 512Mb DIMMs. I know these need to be 168-pin PC100 SDRAM, 10ns or faster, and I know that PC133 is meant to be backwards compatible with PC100.

"You could try the Mac memory scanner from Crucial. It may be able to tell you exactly what memory you can get. The website mentions a money-back guarantee if you purchase the memory through their website and it does not work.

If you don't want to buy it from the website at least it will give you a clearer picture of exactly what you need.

iMac G3/500 is listed on the site, so it should work.

This is what will probably come up:

512MB Part #: CT223786 • SDRAM,
PC133 • CL=3 • Unbuffered • Non-parity
• 133MHz • 3.3V • 64Meg x 64 • •

512MB Part #: CT260476 • SDRAM,
PC133 • CL=2 • Unbuffered • Non-parity
• 133MHz • 3.3V • 64Meg x 64 • •

The original RAM I tried was ECC. I tried some non-ECC RAM (as the one that came with the iMac was), and it worked fine. Maybe I just got lucky, or maybe that's the whole answer. Either way, I hope this finding helps someone else.
