Two things to look at my friend..
TEMP, CPU especially. Even if your temps are within range and no other games cause problems this can cause this issue in C3. Try opening up your case and putting a fan on it and see if there is any improvement. My 3960x stress tests all day but needed to back off the OC for this game..idk why.
Memory clock, try loosening up the timings or lower the frequency.

Yep, just like Tomaj said. Crysis 3 is sensitive in terms of CPU overclock. Might be the engine or a code. Many of us had to fine tune more their already stable OC.

Or simply monitor temps with Realtemp with log file enabled, my 2500K doesn't cross 70c @ 4.7ghz (H100 cooler).

More likely it's his 2133mhz RAM, that's pretty damn high frequency, must be running on high volts (or super loose timings).
