AMD Llano A8-3850 Overclocked to 4.9GHz

One of the shops in Japan, Overclock Works, did a demonstration for overclockers using extreme cooling on AMD Llano A8-3850 CPU with GIGABYTE GA-A75-UD4H motherboard and achieved a CPU frequency of 4.9GHz. Read on.

The overclocking was done with AMD Llano A8-3850 processor which was rated at 2.9GHz and a GIGABYTE GA-A75-UD4H motherboard. The core voltage was raised to 1.792V (seen from the CPU-Z screenshot above) resulting in a 169.2MHz base clock and a multiplier of 29. The CPU overclocked at this settings (169.2MHz x 29 = 4.906GHz) was able to boot into Windows operating system, but was not stable enough to run a proper Super PI 32M benchmark. 

The AMD Llano A8-3850 had to be downclocked from 4.9GHz to 4.761GHz before a Super PI 32M result could be generated (shown above). The demonstrator then moved on to carry out similar overclocking for the A6-3650 processor, but faced some problems after removing the nitrogen pot. The GIGABYTE GA-A75-UD4H motherboard was unable to work properly and had to be changed with an ASUS F1-A75-V PRO motherboard instead. However, difficulties were reported during the overclocking with the ASUS motherboard and could only achieve a 4.186GHz (base clock of 161MHz) for the A6-3650 processor with a core voltage of 1.428V.
