We tried all of the preset overclocking settings, and each went without a hitch. The process essentially comprises of clicking the setting you want, wait for the reboot, and presto, you've got an overclocked machine. The 4.58GHz settings, which delivers a very nice 35% overclock. A pretty simple, no BS way to get a nice perfromance boost. The setting is aggressive on the BCLK at 104 MHz, but the 1.320V core voltage is not too bad. The temps on the Cooler Master TPC 812 were also an acceptable 72°C, but probably a bit high as a 24/7 OC setting. An AIDA64 stability testing was used to monitor a stress test, and showed a very low-ripple voltage response, so Gigabyte's Ultra Durable design does pretty well.
Intel offers yet another method for overclocking that is easily set up through the BIOS and is completely automated. It is called "Extreme Memory Profile" (XMP), and it is a very simple yet effective way to overclock a computer with essentially no risk. Overclocking is still an enthusiast's game these days, and XMP is one way Intel is trying to bring the masses into getting more out of their PCs. XMP didn't do much to overclock the CPU, bumping it to 3.8GHz, but it allows 1600MHz XMP.-enabled RAM to auto-set at 1600MHz instead of the 1333MHz default.
Automatic OC'ing is straightforward and dead-simple to use, but alot of you will be tinkering plenty to get the OC you want. Manual overclocking is the same animal it has been for some time, and we wer able to match the 4.58FGHz setting, shaving 0.2V off the buffer Gigabyte has built in for chip variability to 1.300V. We could probably wiggle it a bit lower, but this was a good, stable voltage which saved us a couple degrees on the CPU temps.
