I bought this Viper Xtreme memory a few weeks ago. I have a Gigabyte GA970A DS3P mobo and AMD FX 4300 CPU. I left the settings at default 1333 for a few days and then enabled XMP which showed memory running at 1866 with correct timings and RAM voltage. BSOD every time. Reset to 1600 with same result. Been in touch with Gigabyte who are hopeless. Initially they suggested I should reflash the BIOS and gave me an incorrect link etc. They now say that they "think" this RAM "may" not be compatible with my setup. Can anyone suggest a solution please? Thank you.
