Here, this is not mine but this is what it looks like.
http://cdn.technorms.com/assets/ASUS-UEFI-BIOS-Utility.jpg Under the dram status tab, Corsair 8gb 2133mhz. Previous kingston dimms showed 2666 which they were. Now, Corsair shows 2133mhz. I think it is something with Corsair's labeling? And I think motherboard forced to 2133 for once because of overclocing fail. That problem fixed after resetting the settings.
By the way good news. I can get 2933mhz instead of 3000mhz, and I've even pushed the timings to cl14 and cr to 1. I think it is much better. I can't get 3000mhz for some weird reason. Maybe vcore needs more voltage there, but i didn't want to push 1.35 further. Thanks for helps.
Current settings,
4.4ghz
2933mhz
vcore: 1.3 adaptive (1.344 max)
vccio: 1.128
vcssa: 1.216
dram: 1.36
