I am not sure why there is "amd only" ram. I think when I checked into it I was told it was just a different way to market. No, this is not why. There certainly is DDR2 RAM that will only run on AMD systems. I can attest to it. I'm tech support for a private school and this summer I bought a gaggle of those "AMD only" DDR2 RAM kits off ebay to upgrade our school's computers to 4 gb to be able to run Win 10 more efficiently. Most of the machines are AMD but some of them were Intel based and most of the Intel based machines would no boot off of that RAM even though the frequency was appropriate for both. This is very common with OEM products. They can be very proprietary. However, after market generic retail RAM kits will work on either - like GSKill or OCZ. With the coming of the DDR3 generation I think AMD abandoned that proprietary scheme and there is now more universality.
IIRC the high point for DDR2 was 1066mhz, and I am not sure if the Kingston/AMD troubles existed back in DDR2 days. But if you want to be absolutely certain you get compatible hardware then see if you can find something on the QVL (qualified vendor list), which you should find on your mobo spec page somewhere. You aren't limited to the QVL but those have been tested by the company and are *supposed* to work (I have heard of times where QVL listed items did not work, but it is still the safest)
