Features of the GA-K8T890-8 Continued


- Overclocking


Being a value orientated board, we weren't expecting to see much in the way of overclocking, however, Gigabyte has provided some of the basics in order to get your system up and running on the overclocking side.


One of the quirks of Gigabyte boards is hiding the advanced settings from users who simply wouldn't have any idea what they are doing. In order to get all the options up you need to press CTRL and F1 from the main screen to get the extra features up. Once done the overclocking settings are located under the Frequency/Voltage Control menu.


Under the Frequency/Voltage control menu there are only four major overclocking settings - K8 Ratio Control, CPU FSB, DIMM over-voltage and CPU over-voltage.


- K8 Ratio allows you to select a ratio from your CPU's highest (depending what CPU you run) down to 8x, Only Athlon 64 FX can go higher ratio then their CPU default.


- CPU FSB allows you to adjust the CPU's bus frequency from 200MHz (default for all K8's) up to a max of 225MHz. The only problem with this is there is no HyperTransport link speed adjustment, so your CPU is stuck at 5x, limiting the bus overclocking, and with no voltage control to increase the LDT speed, bus overclocking is virtually cut to nothing.


- DIMM voltage adjustments are from default of 2.5 up to a max of 0.3V+ in 0.1V increments. CPU voltage is also very limited with only 0.25%, 0.5% and 0.75% above CPU default...not the world's most overclocking friendly board.


As mentioned, with all these limiting factors, we only managed to increase the FSB from 200MHz up to 212MHz before the system refused to load Windows.
