Dual rank DIMMs with denser or less dense chips shouldn't make much of a difference in terms of compatibility. Personally, I'd get the "AMD Only" sticks especially given the price difference as a test - if they work, fill out all the machines.
They're at the upper edge of "old" Intel memory support voltage, but they should work just fine.

Core 2 chipsets only supported 2gbit chips for DDR3 which today would be considered very low-density, while Ivy-E and newer Intel, + all AMD support high-density 8gbit chips. So that "AMD Only" DDR3 should work fine in any 4xxx+ Intel too.
