or rebooting the OS. With micro adjustments of the CPU PLL, NB, NB-PCIe, and
DRAM voltages in 0.02v intervals, there are no limits—only extreme results to
break new OC records! See page 4-28 for details.
ASUS True 16+2 Phase Power Design
The breakthrough technology of 16+2 phase VRM design is bringing to the
ASUS motherboards. 16+2 phase power design (16-phase to vCore; 2-phase to
vDRAM/QPI controller inside CPU) can reach high power efciency, dispel heat
generated by VRM module effectively, and lower more temperature compared to
other VRM solution. With the high quality power components such as low RDS (on)
MOSFETs, Ferrite core chokes with lower hysteresis loss, and 100% Japan-made
high quality conductive polymer capacitors, ASUS 16+2 phase VRM design also
ensure longer component life, minimum power loss, and help to reach the superior
overclocking score ever than before.
