uncore mhz und vtt voltage als diagramm

lt. Diagramm ist die kurve ab ca. 1,36vtt (QPI-Voltage) bei 3912 mhz uncore takt nicht mehr sehr linear.

d.h.-> max ram takt wäre dann so ca. 978MHz (Uncore 3912/2 = 1956/2 = 978MHz)

also 195FSB mit x10 (5.0) wäre Ram auf 1950 (975MHz) bei 1,36vtt voltage.
