BIOS
The BIOS of Gigabyte EP45-UD3R is based on the Award BIOS Phoenix version.
The basic kit of memory latency timings is located in the overclocking section:
Additional memory timings are located in numerous subsections:
As we already stated, the board supports a great number of memory frequency multipliers, and each of them can operate with a few predefined parameters (they are marked with letter):
Finishing our talk of the memory settings, we note support for the Intel X.M.P technology.
Now move on to the section to do with the system monitoring.
The board displays the current voltages, as well as the rotational speeds of all the four fans. Note that the CPU cooler is able adjusting the rotational speed depending on the CPU temperature.
The board is able storing and loading the BIOS settings as profiles (eight profiles are available).
We also note that the Gigabyte's board offers the integrated Q-Flash utility which is aimed at updating the BIOS firmware.
At the same time, the Gigabyte board supports the Windows utility @BIOS which is really handy to use.
Overclocking and stability
Prior to moving to overclocking, let's look into the power converter. It uses a 6-phase power scheme, in which there are three 270 mkF and nine 820 mkF capacitors.
Also, the Dynamic Energy Saver Advanced technology operates most efficiently only with Intel's latest processors. In other words, to make the motherboard switch the power supply mode into the 1-phase mode, the processor should be made following the 45-nm technology and support the PSI signal.
Below listed are the overclocking features.
| Motherboard |
Gigabyte EP45-UD3R |
| Multiplier adjustment |
+ |
| FSB adjustment |
within 100 to 1200 MHz (1) |
| Vcore adjustment |
within 0.5 to 2.3V (0.00625 V - 0.02V) |
| Vmem adjustment |
within 1.45 to 3.04V (0.02V - 0.05V) |
| Vdd adjustment |
within 0.85 to 2.0V (0.02V - 0.1V) |
| Vsb adjustment |
within 1.1 to 1.4 V (0.1V) |
| Vtt adjustment |
within 1.1V to 1.7V (0.02V) |
| Vpll adjustment |
within 1.05 to 2.81V (0.02V - 0.1V) |
| Vsb-io adjustment |
within 1.05 to 2.31V (0.02V - 0.1V) |
| PCI-E adjustment |
within 90 MHz to 150 MHz (1) |
So, we've got a complete set of overclocking tools which in theory is able providing maximum overclocking. At the practical overclocking as well, Gigabyte EP45-UD3R was also on par and was running absolutely stably at FSB = 558 MHz (which is very close to the FSB Wall of the tested processor).
There is also the feature for dynamic overclocking - C.I.A. 2.
The last thing to note - we noticed that the BIOS interface runs relatively slow, which somehow complicates setting the numerous parameters of overclocking. Hopefully, that will be fixed in the forthcoming firmware versions.
