AMD's new 'Richland' A10-6800K processor, which has been elevated to an impressive 8 GHz clock
frequency by Finnish overclocker 'The Stilt'. At this speed, the chip is
currently the record holder (#58)
of all A-series APUs on the world ranking list. The absolute number one
on the list is also an AMD processor, the FX-8150. About a year ago,
this chip was overclocked to a record 8.7 GHz.
The overclockability of Richland APUs comes as good news for AMD. Of
course, The Stilt didn't use standard cooling to increase the frequency
of the A10-chip from 4.1 to 8 GHz. Instead, liquid nitrogen was used,
cooling the system to -186 °C. This temperature allowed the core voltage
to be increased to 1.992 volts. By increasing the base clock to 126.99
MHz and combining it with a 63x multiplier, the 8 GHz frequency was
reached.
For his attempt, The Stilt uses ASUS' F2A85-V Pro motherboard, with 4
GB of DDR3. The memory was clocked at 846 MHz (1692 MHz effectively),
with timings of 9-11-9-24-2T. The HWBot listing reveals that no special cooling was used for the memory.
Unfortunately, no images are available of the setup used, limiting us to the CPU-Z screenshots depicted below.
