My Giga runs with way less core but far more heat, I was going to mention this on the Giga thread but it appears to me the Giga pumps a lot of current into the chip to keep the vcore down where as this DFI doesnt hence needing more vcore. This same chip came out of my Giga with light brown scorch marks on the under side of the chip!!!! I would suggest anyone running 4.5GHz on the Giga check there chips before its to late!!!

Update... I also have a 950 that run high speed in the Giga & it also has some marks but not quite as large as the 930 see pic.
wow those burn marks are scary , what giga where you running with what voltage the Gigabyte GA-X58A-UD3R ?
