+* Maximum DDR3 speed depends on the BIOS version. BIOS versions up to 1.28 allow RAM speeds up to 1866MHz. BIOS versions 1.29 and above limit RAM to 1333MHz. Modified versions of BIOS available that remove this limitation.
 * The combined headphone/microphone jack is a 4-pin TRRS connector and is wired as per [http://en.wikipedia.org/wiki/Phone_connector_(audio)#TRRS_Standards CTIA/AHJ] standard (tip - left, ring1 - right, ring2 - ground, sleeve - mic). Which means, it is compatible with most modern cellphone headsets (including Apple); however, it is not compatible with older Nokia and Samsung headsets wired as OMTP.
