“Does this RAM run at 1600 MHz setting with JEDEC alone? Or does this RAM require BIOS XMP support to run at full speed? My system only supports JEDEC and does support PC3-12800. XMP is an Intel extension, AFAIK, and I have an AMD system.”

yes it dose
Sorry, there was a problem. Please try again later.Needs xmp support to run at faster 1600 but has no xmp 1600 also
Sorry, there was a problem. Please try again later.Short answer would be yes? JEDEC is the organization that defines and manages the standards. SPD and XMP are standards. SPD is a JEDEC standard and XMP is a non-JEDEC standard. The difference mostly being in how the data tables are defined. Basically, if your motherboard supports the parameters specified in the data table stored in the EEPROM, it will run at that particular speed. I don't recall seeing anything specific to XMP on these and don't see any reference to it on their product page. Pretty much all modern motherboards utilize SPD over SMBus to read the EEPROM on the memory module which contains a speed or set of speeds that the memory is manufactured and verified to run at. These particular modules are configured to run at either 1333 or 1600, depending on the capability of the motherboard. The available list of speeds you typically see in your BIOS are what is being read via SPD.
