[Sorry if this basic question was answered in a previous thread - if so I couldn't find it!]

I have a PPC (G5) iMac circa 2005. Need to upgrade the RAM - currently have only one DIMM slot occupied with a 256MB chip. (Yes it's lame, I know. Obviously I'm not a power user.)

I've read/heard many times that it's best to balance both DIMM slots with RAM of equal capacity. Third party reseller sold me two 1GB chips, but one of them is labeled PC3200 DDR and the other is PC2700 DDR.

I've read that 3200 and 2700 are functionally equivalent in some ways, but will there be any problem/risk in using them together?

Thanks for any education you can provide...

I would not use those together. Only use exact matching pairs, preferably exact to the brand and part number. Mixing RAM from different brands, even if the specs are otherwise identical, can sometimes cause issues. Using sticks that have different specs like yours is definitely asking for trouble. I would get back to them. They may have sent the wrong one by mistake.
