You said that your system is quite similar, so you'll also likely have a similar UEFI DualBIOS. With the GA-H77N-WIFI UEFI DualBIOS (BIOS Version F2) there are two sections where these settings can be altered. SECTION 1: On the M.I.T. (main or home screen) you'll see a menu entry "Advanced Memory Settings." Hitting enter will show the "\M.I.T.\Advanced Memory Settings" screen where the "Extreme Memory Profile(X.M.P.)" setting can be changed from "Disabled" to "Profile1" (using the -/+ keys). Alternatively, you could change the "System Memory Multiplier" from "Auto" (13.33) to "16" which also changes the greyed out "Memory Frequency(MHz)" from "13333MHz" to "1600MHz." Note that changing the "Extreme Memory Profile(X.M.P.)" to "Profile1" also changes the greyed out "Profile VTT Voltage" from "1.05V" (default) to "1.20V."

This "M.I.T.\Advanced Frequency Settings" screen also provides access to the "Extreme Memory Profile(X.M.P.)" and "System Memory Multiplier" settings.

I tried standard BBCode size options inside the IMG (and IMGLightBox) tag, but these were ignored (at least in the preview post). Basic HTML <img> tags also appear to be ignored.
