Therefore, the first thing that needs to do
in the CPU overclocking process is unable the “Core performance boost”
technology in order to prevent it from intervening in the process, and only
after you increased the CPU’s clock. However, we had to stop the overclocking
process test for AMD A10-5800K almost immediately because we were really
shocked with the power consumption level of the system, over the regulated
level of 200W. In fact, it is unfair to compare directly this platform with
Intel LGA 1155, because the later generation will recognize the former
generation’s unfavorable conditions. In order to figure out the power
consumption of Intel processor, we used a special version of LinX utility. This
version used the AVX instructions and created a higher operational level. The
system was equipped with a discrete graphics accelerator, the Intel Core
i5-3750K processor, and some top mainboards with the central PCI-E ports,
contributing inconsiderably to the power consumption level of the whole system.
However, with such factors, we still saw a disappointed power consumed level of
the LGA 1155 system, still almost 200W although not over that level yet.
Nevertheless, while overclocking the AMD A10-5800K, the processor, which is not
the most powerful one, while using the mainstream mainboard and integrated
graphics core, the power consumed parameter exceeded the level 200W quickly.
We used all of the power saving technology
not only in the nominal mode but also the overclocked mode. Normally we lowered
the score of the mainboard even when the power consumption level exceeds the
regulated one few watts, and the difference here is 10 watts, while the
operational performance simply cannot be the same. We were so shocked that we
were about to give up the AMD processors for the better ones. For instance,
some countries give up in using the regular light bulbs very slowly to continue
with the more efficiently power saving ones. The problem here is just the same:
if the processors of AMD need more power for the same tasks, they might not be
used any more for those tasks. However, once we find our comfort, we decided to
discover how each component in Socket FM2 contributes to that level of power
consumption.
The overclocking principals are the same
for every system. If we increase the frequency, the voltage must also rise in
order to reach the balance. A challenge for overclocking process of Socket FM2
processor is that AMD was failed to integrate the thermal sensor into their
processor. This explains why we chose Vcore as the priority, not the CPU
temperature. 1.55 V is considered to be safe for the Socket FM processors. Our
tests showed that in this Vcore setting, the maximum possible frequency for
this special AMD A10-5800K processor is 4.5 GHz. At the same time, we also
increased the memory frequency and gently adjusted its timings.

More than that, the frequency of integrated

During our tests, we did not face any
problem with the Gigabyte GA-F2A85X-UP4. It guaranteed the system nominal
operation to be stable. Just the memory with the frequency of 1,333 MHz needed
to adjust the timing from 9-9-10-24 to 9-9-9-24. The parameter was recorded in
SPD module. This issue is not necessary to discuss too much. Traditionally,
Gigabyte BIOS mainboard has no tool to automatically overclock and you can use
their Easy Tune 6 utility to implement this process. However, “Turbo CPB”
parameter in BIOS allows you to fix some problems of the “Core performance
boost” and quickly improve the performance. If the numbers above are allowed,
the clock frequency will always be allowed to increase to the peek thanks to
the Turbo Core technology in your special mode, in this case it is 42x. We did
not also face any problem in overclocking the processor manually, but
overclocking the graphics core has some obstacles. Everything seems right. BIOS
allows adjusting the frequency 1 MHz once, but the obstacle is that the
practical frequency of the graphics core completely follows very different
principals. For instance, we started with the frequency of 1,000 MH, but in
practice, the integrated graphics card worked at the frequency of 950 MHz. We
increased to 1,050 MHz, again it was just 1013 MHz in practice. It turned out
to be very inconvenient to predict while we are looking for a suitable value,
and this is also a problem of the BIOS mainboard. ASUS mainboards can offer
more useful algorithms to adjust these graphics core’s frequencies. First of
all, they have a lot of overclocked configurations, and in manual configuration,
we just need to choose one out of those frequency value to calculate the
graphics core’s frequency.
