If the screenshot above is PSC, then you'd need LN2 for such clocks which makes the result not impressive.
Gigabyte has a lot of problems running PSC and BBSE, but on ASUS it's not a breeze either. The same kit/settings that boots up 1400 8-12-8 will frequently crash in 32M at 1300 8-12-8 for no apparent reason.
If we're talking about the same kit, the "2800C8" stuff is a 2400 9-11-9 rated G.Skill PIS set produced on week 1127.
On air, that does 32M at 1200 7-10-7 at 1.59V (auto subs), 1200 6-11-6 at 1.82V (auto subs) and 1300 7-12-7 at 1.71V (auto subs), roughly 40-50MHz or 0.05-0.06V better than any retail PSC I have ever tested or seen.
