I need to upgrade my RAM as the measly 1GB is slow and my apps are demanding more....

Can you upgrade to 800 MHz DDR2 SDRAM if you have a 667 MHz in your iMac or do you have to use the same spec?

I want to purchase the 4GB APPLE MAC IMAC RAM 800MHZ DDR2 SDRAM KINGSTON 2X2GB LIFETIME WARRANTY.

Always replace or add memory with the exact type and speed that Apple has installed. OWC or Crucial are the best places to shop for memory.

According to Apple your machine can take 4 GB, Mactracker says it can actually take 6 GB.
