Raise voltage isn't a science but you need do it carefully or can damage your CPU or components. Take a look of the guide and let me know if our need more help.
Yeah thanks for the link saint19, but I am wondering if anyone has had actual experience with using both the 1090T and the 990fxa-UD5. Much issues with Vdroop on mild overclocks, etc.
Gigabyte have high vdroop in mid rig mobos like your and mine, the overclock is based on the same process but the chipset is different, so, the voltage for stability is different as well as the max overclock.
