Would this RAM fit my iMac?

Would this RAM card work with my iMac (late '06)? Currently I have two 512MB cards, and I want to replace one of them with the 2GB card shown in the link which = 2.5GB RAM in total.

Apple's specs for my iMac's RAM are:
667MHz DDR2
(PC2-5300) SO-DIMM

Also, is it okay to have unmatched RAM cards? I'll have an Apple 512MB and a 2GB running together. Will my RAM run in single channel mode if it's unmatched?

Thanx

Yes, that SO-DIMM chip looks like it will work fine.
You don't have to install same-size pairs - although there can be a (slight) speed advantage by installing same-size pairs. Your iMac will function fine with the memory setup that you describe.
