Gigabyte G1 Gaming GTX 1080’s product page included Xtreme Gaming’s OC utility. Apart from its skin, there shouldn’t be any differences in its function. The utility can be used for manual overclocking, saving OC and fan profiles & customizing the lighting options.
There are three clock profiles: ‘Eco’ ,’Gaming’ and ‘OC’. As said earlier, Gaming profile is enabled by default. The Eco mode reduces its base clock down to 1607MHz. While its base clock is the same as its Founders Edition, the eco mode’s boost clock is up to 1746MHz. Also, there are three fan profiles with manual setting options and LED settings with six presets.
This is the first time I’ve seen ‘audio flashing’ LED light effect on a graphic card. But to be fair Gigabyte motherboards did have this function.
With other GPU overclocking utilities, they have a separate function for “apply” and saving/loading the profiles. But the Xtreme Gaming utility overwrites the currently selected profile once a new manual setting is applied. This is not a good idea as you one may lose the previous stable overclocking setting while experimenting with more overclocks. The only workaround is to load another profile and then overclock further. Gigabyte should have the manual profile save button and not let the utility overwrite the new and untested overclock settings.
This review unit reflects 92.8% ASIC quality, the highest I’ve seen till date. Higher the ASIC quality, lower its power consumption and better overclocking potential. It’s OC profile provides 115MHz over its FE spec’s base clock.
The first attempt was a +135MHz increase and 19% increase in its GPU voltage. The only time this setting crashed was with Fire Strike Ultra’s GPU Test 2 run. It did generate GPU Test 2 score. I’ve reduced it down to +120MHz with +35% GPU voltage and it worked.
|Reference||Gigabyte G1 (Gaming)||Gigabyte G1 (OC)||Gigabyte G1 (Manual OC)|
|Base||1607||1696 (+89)||1722 (+115)||1816 (+209)|
|Boost||1734||1835 (+101)||1860 (+126)||1955 (+221)|
Compared to Founders’ Edition base clock, that’s a 209MHz. This chip allowed 94MHz bump in base clock over the OC profile’s base clock. That’s pretty good seeing that its OC profile already provides a +115MHz increase compared to FE’s base clock. The manual overclock’s boost goes up to 1955 MHz.
With Fire Strike Ultra running in its background and fan manually set on auto:
Within 50% fan speed, the overclocked card manages to stay cool at 68 degrees Celsius. Even with the reduced material and heatpipe count, the cooling system is doing a good job with the additional 94 MHz increase over the overclock preset profile.
With the same settings, the following performance boost is achieved.
