I got some 2x256mb pc100 sdram chips recently, and they dont work with the iMac.

They appear to be double-sided (chips on both sides). Is there an issue with double-sided sdram memory in a slot-loading iMac?

Or..I'll have to try Single sided SDRAM (currently in).

Never had an issue with double sided. I even had two 512MB sticks in my 350MHz once.

Double-sided RAM cards should pose no problem, as that implies low-density chips as the CRT iMacs need, The specification, which you may not have if you were not aware that you needed it, is 168-pin, 3.3-V, PC-100, non-ECC, unbuffered, unregistered, low-density SDRAM, with no more than 16 chips per card, and no more than 512MB per slot.

^^^ ECC is not your friend in a Mac; I've had no luck with it in any model. Which is too bad, since I have a stack of the stuff.
