System Info-
Asus Z87-PLUS (Bios Version - 0903)
Intel Core i5 4670K 3.4Ghz (Stock)
Cooler Master Hyper 212 EVO
Adata XPG V2 1600Mhz 2x4GB
EVGA GTX 760 2GB w/ ACX
Corsair RM650 80+G

Anyway-
I put this system together about a week ago and everything has been running fine. When I turned my system on today, The CPU LED stayed lit and the screen remained in sleep mode. So after about a Min, I held the power button to shut off

When I turned the computer on the second time, I was greeted with a nice little message on an Asmedia Screen saying my overclocking had failed. So I returned to my BIOS and loaded the optimized defaults. After that, I loaded into windows No problem

Im confused. The only "Overclocking" Ive done is Enable XMP for my DRAM. And now, when I enable XMP 1600Mhz, Asus EZ Mode still only reports 1333Mhz for both of my sticks...

Any Ideas?

You might have to manually set those Ram sticks to run at their advertised speeds. I'm not fond of Adata Ram myself, but it should set itself fine with the XMP profile. Make sure the timings are set correctly too(CAS and such).

Thanks, Ill give that a go if I have a failure again. CPU-Z Is reporting the Correct RAM Speeds (800x2). Asus EZ Mode does report 1600Mhz at the top in System Information. Im guessing the actual DIM Info just shows Stock Speeds.

One other question, Im somewhat new to Overclocking, Im guessing such a scenario when I turned on my PC is the norm?

Seeing an American Megatrends screen going "Overclocking FAILED"?
 
Could be if you actually tried to overclock with that Ram. Just because it's guaranteed to run at the rated speeds, doesn't mean you can push any higher than that. Or, if you can, you might have to relax some of the timings to get there. So, let's say that rated speed is 1600mhz, at CAS 9, to get to 1866mhz you might have to drop down to CAS 10. That's just an example though.
