Increasing memory bandwith in BIOS

Hi all, i have never OCéd RAM before, i have overclocked my CPU before but today i was reading about overclocking memory, i went into BIOS and changed my DRAM Frequency from 1333 MHz to 2133 MHz without changing anything at all and to my surprise the computer looks stable.

I have run few games, a 10 min aida64 stress but the pc doesn't seem to crash. Now i was also reading that increasing bandwith also increases latency but i haven't touched on latency yet.

What i want to ask is if my pc is stable at this frequency without changing latency is it worth keeping it here without changing latencies? That seem a bit more complicated.

My specs:
i7 4770k
Asus maximus VI hero
Corsair DDRIII RAM CMP32GX3M4X1600C10 (2x 8GB)
GTX 1080

Look in CPU-Z (free app) at the memory tab, and see what the freq shows and let us know. Jumping from 1600 to 2133 would be very strange with no other changes to timings or voltages. Would guess the OC failed and it went back to 1600 or even 1333. If the frequency shows as 800 in CPU-Z you are at 1600 (DDR = DOUBLE data rate). if it shows 1066 as freq then let us know what the timings are at

I ran Time Spy benchmark and it posted a bit higher score then before so i guess OC is indeed working. I have played Guild Wars 2 about 3 hours straight now without any crash. Here's a CPU-Z screenshot:

I might try higher clock to see if it crashes or not, although my RAM speed is 1600 MHz it has been running 1333 MHz all this time (about couple years now lol) and now i did 2133 MHz and it worked without any problem.
