Conclusion

The obtained results show clearly that overclocking Llano processors in Socket FM1 systems is a rewarding thing. As we can see from the experiments with our A8-3850, the processor core frequency may be successfully increased to 3.6 GHz and the graphics core can work at about 850 MHz. Such overclocking boosts the performance by about 25-30% in both: computational tasks as well as gaming applications. This boost allows us to view Lynx platform with a hybrid Llano processor as an entry-level gaming solution, as it provides comfortable gaming experience with acceptable quality settings even in the latest gaming titles. And I have to admit that it sounds fantastic, especially since we are talking about a processor with an integrated graphics core inside.

The actual Llano overclocking procedure is fairly easy and requires increasing the clock generator (BCLK) frequency. It is important to remember that for the best results you have to set BCLK frequency as well as memory frequency to their maximums.

Since Llano is pretty power-hungry and runs quite hot, it would help a lot if you had a high-performance processor cooler. It is also highly recommended to get a quality mainboard that could ensure stability at high BCLK frequencies and at the same time have a powerful voltage regulator circuitry.

According to these criteria, Gigabyte GA-A75-UD4H has every chance to become a good Socket FM1 platform for enthusiasts. It has everything this user group usually needs. The voltage regulator is very well made, has 8+2 phase structure and uses only high-quality components. The BIOS has all settings and parameters necessary for successful overclocking. The expansion capabilities are also very promising. The mainboard supports one or two external graphics accelerators. It has a lot of USB 2.0 and USB 3.0 ports, and SATA ports support 6 Gbps speed.

Nevertheless, once we’ve take a real close look at Gigabyte GA-A75-UD4H, we are left with the feeling that this mainboard is not at the forefront of modern technology in many aspects. And it is not about the exterior appearance, but mostly about the fact that its BIOS, actually, takes us a few years back. Its interface is obsolete and its internal structure is very confusing. However, these issues do not affect the performance and overclocking success, so in a way we can overlook them.

On a much broader scale, however, we have to question whether we really need mainboards like Gigabyte GA-A75-UD4H at all. Having designed a full-size high-quality mainboard with a powerful voltage regulator circuitry and a number of additional onboard controllers, Gigabyte got to the point where the final price of a product like that reached as much as $123. In other words, its price is in the range of the top Socket FM1 processor – A8-3850 ($135). So, it turns out that Gigabyte GA-A75-UD4H is an expensive mainboard for inexpensive systems. So, why will be the target user group in this case?
