Overclocking


I managed a decent overclock topping out at 4.5 GHz with the Gigabyte F2A85X-UP4. I was able to push my AMD Performance Edition memory to 2133 MHz, and I was able to tighten timings. It will be interesting to see how memory clocking goes on all these different FM2 boards I have here.

What I do not have pictured here is reference-clock overclocking. Gigabyte has equipped the Gigabyte F2A85X-UP4 with an external PLL loop that should allow for bus clocking above 133 MHz. I managed to reach 142 MHz, but this setting actually proved to be less efficient, and scores were better with an adjustment to the APU's unlocked multiplier. The scores presented today are scores achieved with the settings shown above.

Overclocked Performance Summary

I have really changed how I do my overclock testing with motherboards. Every single test you see in the main section is repeated in the section that follows, including power consumption. As I test more products, a good picture of overclocking efficiency should emerge, which should prove interesting when it comes to those products that are 100% overclocking-oriented. I have grouped results into sections, and all products are tested with 4.5 GHz CPU speed on the APUs. Memory speeds vary depending on the APU's ability. Here, I have results with both the A10-5800K and A8-5600K. I'll include results with both APUs as I test these FM2 boards.

My A10-5800K seems to allow for higher memory overclocks than my A8-5600K, which amounts to the majority of the performance difference here. As individual silicon-quality will vary from sample to sample, these numbers are only meant to serve as a guideline for the performance you can get out of your APU in combination the Gigabyte F2A85X-UP4.


The efficient VRM kept power consumed by overclocking with the Gigabyte F2A85X-UP4 in check. There's not too much real info we can glean from these results, but my next review will have figures that will set things apart.
