Final Cut Pro X keeps crashing, so I am looking to upgrade the ram in my early 2008 iMac. I was wondering if I am able to upgrade to 8gb or even 16gb? Also can I use the sticks that are ddr3 instead of ddr2?
iMac, macOS 10.15
You have to use 200-pin PC2-6400 (800MHz) DDR2 SO-DIMMs.
2-4GB sticks will only give you 6GBs in an early 2008 iMac.
This iMac has a maximum limit of 4GB, see Crucial website here: Crucial Ram

Actually that's not the case. As I mentioned, it has a maximum of 6GBs.
See: OWC or Mactracker.
I am guided by Apple, for technical specs of Mac at the support page: https://support.apple.com/en-gb/HT201191#3
The thing to keep in mind, Gary Scotland, is that Apple only quotes what they were actually able to successfully test, at the time of first manufacture.
The technology keeps advancing, in the meantime.
I have found that it is often the case (but never guaranteed) that one can upgrade a Mac to about 2x the maximum Apple quotes, from first manufacture. (They don’t provide updated upgrade specs.)
Fortunately, places such as OWC and Crucial will guarantee RAM upgrades, they sell, for your specific Mac.
(I, relatively recently, upgraded a mid-2010 MacBook, that Apple rated at a maximum of 4 GB, to 8 GB, through such a company, after point-blank requiring them to guarantee the upgrade.
The upgrade went flawlessly. The MacBook reports the proper RAM amount and configuration, and works without a “hitch”.)
That's nice. Just so you know, virtually every iMac made can utilize more RAM than Apple states.
Just to add, the numbers you are looking at are what configurations Apple sold, not the maximum.
can I use two 4gb ram sticks in my early 2008 if they have ddr3
