Here are the specs on G.SKILL's website:http://www.gskill.com/products.php?index=422
M/B Chipset Intel Z77, Intel Z68, Intel P67, Intel P55
XMP Ready for 1st, 2nd and 3rd Generation Intel Core Processors
Compatible with AMD platform
Looks like those modules were designed for Intel platform and G.SKILL is trying to assure us that it will also work on AMD platforms.
It might. Just try it. It won't kill the modules or damage the board. If the modules have an XMP profile, then it is best to load that profile in the BIOS.
I hope that you are using 2 modules (dual channel) and not just 1.
