BIOS
The BIOS of Elitegroup A790GXM-A is built on the AMI BIOS version.
The extended pack of memory settings is in the "M.I.B" section:
The parameter in charge of selecting the memory operating frequency is also over there:
Now move on to the section to do with the system monitoring.
The board keeps track of the CPU's and system's current temperatures and rotational speeds of the three fans. Besides, the user can control the rotational speed of the CPU cooler with the Smart Fan feature.
There are few parameters for tuning the integrated video core. One of them allows allocating memory capacity for the needs of integrated graphics:
There is one more parameter that determines the speed of the integrated video memory:
Overclocking and stability
Now let's look at the power converter. It uses an 5-phase power scheme in which there are five 270 mkF and ten 820 mkF capacitors.
There is a small radiator on the power components:
Now on to the overclocking features:
First off, Elitegroup A790GXM-A allows adjusting the HTT speed within 200 to 355 MHz in 5 MHz increments. Secondly, the user can adjust the HyperTransport bus multiplier between the NB and CPU:
Here are the remaining overclocking tools:
| Motherboard |
Elitegroup A790GXM-A |
| CPU multiplier adjustable |
- |
| HTT adjustable |
within 200 MHz to 355 MHz (5 MHz) |
| Vcore adjustment |
within +0 to +0.3V (0.02 V); |
| Vmem adjustment |
within +0 to +0.63V (0.01V) |
| Vdd adjustment |
within +0 to +0.315V (0.005V) |
| Vsb adjustment |
within 1.2V to 1.35V (0.05V) |
| Vsp (V SidePort) adjustable |
within 1.8 to 2.1V (0.1V) |
| PCI-E adjustment |

We attained the maximum stable HTT frequency which amounted to 250 MHz:
And this result is the same both when using the integrated video core and using an external video card.
As regards the integrated graphic core, it retained its functionality to frequencies up to 930 MHz:
