Intel P45 Motherboard Roundup: MSI, ASUS and Gigabyte
Gigabyte EP45-DS3R BIOS
Though very competent in most areas, the Gigabyte EP45-DS3R BIOS does leave a little to be desired in terms of option organization and ease of use.
The first page of the BIOS takes you right to the goodies that enthusiasts and tweakers are interested in including support for your overclocking options and voltage settings, etc.
The FSB on the CPU, that runs at 333 MHz by default on 1333 MHz FSB processors, can be set as high as 1200 MHz (4800 MHz effective) though you will likely never want to even attempt to run anything that fast. It is also the base clock on which your DDR2 memory speeds are set.
Gigabyte continues to use an odd way of setting the memory multiplier on their P45 and X38/48 motherboards that makes you pick between various multipliers as well as the FSB speeds. Why this is I am not sure but Gigabyte seems to indicate that by making this distinction they are able to produce a more overclockable and stable environment - your mileage will vary.
Here you can adjust more advanced memory timings than just CAS latency, etc (of course those are available on the previous screen).
There are a lot of voltages that the Gigabyte motherboard allows you to control and really pushes the limits of safe computing and overclocking. For example, the 3.04v that is currently showing going to the DDR2 memory bus would NOT be recommended for anyone but the most serious of overclockers.
Finally, we can see that the Gigabyte EP45-DS3R at least has standard hardware monitoring functions for voltages, temperatures, fan speeds, etc.
