Running on a Gigabyte 990-XA-UD3 Rev 1.1 with 16gb RAM and 1333mb of memory, equipped with CPU water cooling.
presently at 4.2ghz (multiplier = 21) manual overclock, no issues encountered. I attempted to push the multiplier further but faced limitations. When increasing the multiplier beyond 21 and adjusting the voltage during boot, the processor caps at 3.4ghz in hwmonitor. The voltage cannot exceed 1.3v even when set to 1.4v, and the CPU Z setting displays a multiplier of 17, which is lower than the 21 I previously configured.
I have reviewed various guides and videos, but consistently achieve the same outcomes.
Any suggestions from fellow users?
I can share screenshots and additional data if needed.

These configurations are currently effective; raising the multiplier to 4.4ghz still results in 3.4ghz in hwmonitor, with voltage increases up to 1.4v producing identical outcomes. The CPU multiplier remains at 17, not exceeding the 21 I set in BIOS.

CPU FM x21.5 4300 MHZ
CPU Voltage 1.3000V
NB FM x13.0 2600MHZ
CPU NB Voltage 1.4000V
HT Bus Speed 2400 MHZ
HT Bus Width 16 bit
Kingston Hyper Fury Black 32 GB 1866mhz down clock to 1600mhz This board doesn't support 1866mhz?

This configuration works well for me – temperatures stay around 45°C on the main CPU and CPUUTIN reaches 65°C, passing tests with prime and OCCT

I can't send you a screenshot directly. However, I can guide you on how to check your CPU temperatures using your system's settings or monitoring tools. Let me know if you'd like instructions!

Updating to disable cool & quiet doesn't affect performance much, it seems unusual since no one else has reported the same problem. I'd prefer it on, but I'm not sure if others have experienced it too.

It is advised to turn off cool and quiet features when overclocking.

I've learned that the key to a pro overclock involves turning off 'cool and quiet' to discover a genuine maximum stable OC. Afterward, re-enable it and experiment with voltage offset until it stabilizes with 'C&Q' enabled. So far, this is the furthest I've gone. Not sure what an 'offset voltage' actually means, but it's something worth exploring further.

Regards to the OP, I own an FX 8370 OC at 4.65MHz.
Before starting the manual OC, I checked HWMonitor and reviewed the boost auto OC process, which helped me grasp the manufacturer's recommended limits.
Have you experimented with turning on 'turbo mode' and observing the results?
Alternatively, try manually adjusting the turbo settings to see how they perform?
