BIOS
The BIOS of Foxconn A7GMX-K is built on the AMI BIOS version.
The extended pack of memory settings is in the respective section:
Also there is a parameter in charge of selecting the memory operating frequency:
Now move on to the section to do with the system monitoring.
The board displays the current temperature values of the CPU and system, as well as the rotational speed of the two fans. Besides, the boards displays current levels of the main voltages. Note that the CPU cooler and the cooler plugged in to the SYS_FAN are able adjusting the rotational speeds depending on the temperature of the CPU and the system using the Smart Fan feature.
The Foxconn One utility allows tracing the monitoring data from within Windows. As regards updating the firmware, the user can make use of the Live Update. Also, the user can make use of the Foxconn Logo which allows replacing the boot-up screen image. This can be done with a utility of the same name.
As regards the settings of the integrated video core, the memory capacity allocated for Radeon HD3200 is adjustable:
Overclocking and stability
Now let's look at the power converter. It uses a 4-phase power scheme, in which there are four 1000 mkF and eight 1800 mkF capacitors.
Most overclocking tools are gathered in the "Fox Central Control Unit" section. However, they are grouped rather inconveniently. The situation is aggravated by that faulty settings may result in a dead hang of the system, which is cured only through a complete CMOS reset. But the board lacks the feature for saving the BIOS profile.
Now, let's list the tools which are in charge of overclocking. First off, Foxconn A7GMX-K allows adjusting the HTT speed within 190 to 400 MHz in 1 MHz increments. The user can also adjust the PCI Express bus speed within 90 MHz to 250 MHz. Besides, it is also possible to change the HyperTransport bus multiplier between the NB and CPU:
Secondly, you can't change the CPU multiplier nor that of the memory controller (topical for overclocking the Phenom CPU). In the end, however good a motherboard may be, the real overclocking us unlikely to exceed HTT = 250 MHz.
Remaining overclocking tools:
| Motherboard |
Foxconn A7GMX-K |
| CPU multiplier adjustable |
- |
| HTT adjustable |
within 190 to 400 MHz (1) |
| Vcore adjustment |
within +0 to +0.775V (0.025V); |
| Vmem adjustment |
within +0V to +0.6V (0.05V) |
| Vdd adjustment |
within +0 to +0.36V (0.03V) |
| Vsb adjustment |
within +0 to +0.36V (0.03V) |
| Vht adjustable |
within +0 to +0.36V (0.03V) |
| PCI-E adjustment |
within 90 MHz to 250 MHz (1) |
In practice, it turned out the way we expected: a stable operation at HTT=240 MHz.
Besides the CPU itself, the user of Foxconn A7GMX-K is able raising the frequency of the integrated graphic core from 500 MHz to 700 MHz. As the checks showed, the board was able to sustain such overclocking trouble-free:
In conclusion, we note that overclocking can be done with the Fox One, but this process is rather inconvenient, slow and is suitable for beginners only.
