The clocking issue might be caused by the processor overclocking or a faulty memory.

The outcome varies based on the RAM model you have. When buying RAM marketed for slower speeds, the potential for overclocking your CPU is reduced (Haswell).
Tradesman1 explains the impact of RAM speed and capacity on CPU overclocking capabilities, noting differences between Haswell and other architectures. He also discusses how high data rates from large DRAM amounts can strain the CPU, especially the memory controller. He asks whether overclocking an i7 4770k with 1333 MHz RAM would face no performance limits.
The CPU won't be bottlenecked - no, and sorry but I don't know where you're headed.
Initially you mentioned if the CPU is OCed then you can't OC the DRAM - false.
Then you claimed that lower data rate DRAM limits CPU OC capability - also false.
The CPU and the DRAM you're using haven't been linked together for roughly six years. With a 4770K running at around 4.6 with 1333 DRAM, performance will increase to 1866 or more, depending on your tasks, keeping overall system speed steady or improving.

The CPU and the type of DRAM you use haven't been linked together for about six years or so. A 4770K will handle fine tuning and precise OC (assuming a CPU OC to 4.6) with 1333 DRAM, as the data rate increases to 1866, 2400 or similar, which will boost overall system performance or keep it stable depending on your setup.
It was a real question, I don't know much about RAM and CPU interaction on Haswell/Broadwell chips.
I've overclocked myself by tweaking the BCLK, which does affect memory speed as well as CPU speed (for example with an i5 6400).
By the way, your personal overclock results won't match exactly with others (we all hear about the Silicon Lottery, especially moderators).
My answers are based on my own experience with overclocking and some info from other forums.
You might have more insight into how overclocking functions, but I asked a genuine question and you seemed surprised.
I think I should focus more on details, but calling me naive is unfair.
There are benchmarks showing that faster RAM usage means slower CPU performance (if both are overclocked), which creates an inverse relationship after a certain point.

It's important to stay calm in this forum—it's a place for discussion, not confrontation. Also, most here aren't experts, so the goal is sharing knowledge, not proving superiority.
Keep your hands off, remember you're typing on a keyboard.
I acknowledged your point.
It’s incorrect, as I clarified earlier.
When false claims are made—especially ones that seem definitive—I make sure to address them and explain the reasoning behind it.
This approach helps prevent spreading misinformation, particularly in communities where technical details like DRAM and CPU overclocking can be misunderstood.
It seems I've discovered my solution. Ran memtest on my 8x4 gigabytes of RAM and found three errors. It's tough to say but I think two sticks are bad. Great job, Corsair vengeance. After taking them out I should be able to resolve all the problems. Removed four sticks with 4 x 4 gigabytes of RAM. Ran a stress test; when my CPU temperature hit 79 degrees it looked like the voltage was too high. I lowered it to 1.16 volts at 4 GHz and she's performing well. Now I just need to replace this RAM and I'm good to go.
Updated after numerous RAM swaps and a new motherboard installation. After consulting Intel's warranty and exchanging CPUs, the system is now performing exceptionally well! Thanks to Corsair's Tech Support and Intel's assistance. Asus support was unsatisfactory.
