A Finnish overclocker called The Stilt managed to overclock AMD's new A10-6800K "Richland" APU to a whopping 8000.48MHz with the help of LN2 cooling. Interestingly, all four cores were enabled during the feat!
Skills aside, "The Stilt" relied on liquid-nitrogen cooling that kept the chip at -185°C, a core voltage of 1.992V, a base clock of 126.99 MHz (~127 MHz), and 63.0x BClk multiplier. All four cores were enabled during the feat. Other key components of the bench include an ASUS F2A85-V Pro motherboard, and 2x 4 GB dual-channel memory of an unknown make, running at 1692 MHz (DDR) reports tpu.
