Where to find 1 Gb of ram to upgrade the factory installed ram on a 20" iMac G4

Hey

Does anyone know where to find 1 Gb of PC-2700 184-pin SDRAM (factory installed) to upgrade my iMac G4 (2003, 20 inch USB 2.0) to 2 Gb?

This part of ram from 0,5 to 1 GB.

The other ram part, the user accesible is already updraded to 1 Gb, this I believe is a 200 pin module.

This info I found with Mactracker, it doesn't say much more about it.

The Mac Mini G4 1,5 Ghz (Late 2005) uses 184-pin PC-2700 DDR333 SDRAM (PC-3200 supported; however it will run at only 333 MHz)

Would this run on the iMac?

Thanks

Try OWC/MacSales - they can identify the precise RAM for your Mac and offer a lifetime warranty.

The upper or 'factory' RAM slot of a late model iMac G4 that shipped with an 184-pin PC2700 DDR333 chip can use a PC3200 184-pin chip (of the same specs otherwise, buffer, etc) and it will run as a DDR333 slower chip. The OWC company has good information & product, as do a few other reputable firms.

{A sorted tail of terror and woe accompanies my experience with a AppleCare covered iMac G4, a RAM upgrade, troubleshooting, logicboard failures, 1,000 miles, etc .so I edited those details from this reply.}

The RAM is ok. If you get the correct spec PC3200 184-pin RAM;

there are others that seem the same but are not. I have a running

Mini (Late 2005) G4 1.5GHz w/ 1GB RAM, but lack chip details.

And the SO-DIMM chip in the iMac G4 last model 17"/20", is same

PC2700 DDR333 part the G4 iBook (mid-2005) uses as upgrade.

Good luck & happy computing! 🙂
