Voltages.

There are up to 3 voltages important for overclocking DDR4. For Intel System Agent, VCCIO and, DRAM voltages. And AMD SoC and DRAM voltages. These voltages help to stabilize the uncore domain of the CPU that ties into RAM as well as the RAM itself. The difference between Intel VCCIO and VCCSA and AMD SoC is that VCCIO requires an increase in voltage when increasing memory frequency in Mhz. And VCCSA requires a voltage increase when tightening timings.

DRAM Daily Driver  Extreme 
Voltage  1.20v ~ 1.45v 1.45v ~ 1.60v

Voltages exceeding 1.45v is only recommended for Samsung B-die for daily use up to 1.5v. To consider is that DDR4 kits with a rated 1.5v also have PCB's that can run that voltage as a daily driver. Extreme voltages for daily use is only wise if you can water cool your DDR4 kit.

VCCSA Daily Driver  Extreme 
Voltage  1.10v ~ 1.25v 1.25v ~ 1.30v

VCCSA also is known as System Agent voltage is for the IMC and PCIe domain. Going higher than 1.25v can damage the IMC and motherboard traces and is only recommended with high-end motherboards and short benchmarking and record attempts. System Agent voltages commonly tied to tighter timings but lower-speeds in Mhz. Using more System Agent voltage than needed for a overclock can cause instability.

VCCIO Daily Driver  Extreme 
Voltage  1.10v ~ 1.25v 1.25v ~ 1.30v

VCCIO is voltage for the IMC and using more than 1.25v VCCIO can damage your IMC and motherboard traces and is only recommended for high-end motherboards and short benchmarking and record attempts. More VCCIO is needed for higher speeds in Mhz. Using more VCCIO than needed for a overclock can cause instability.

SoC Daily Driver  Extreme 
Voltage  1.00v ~ 1.20v 1.20v ~ 1.25v

SoC voltages help to reach higher FCLK(Infinity Fabric), MCLK(Memory Frequency) frequencies, and tighter timings. Extreme voltages are not recommended and commonly used for HWbot extreme overclocking scores. And will require a beefy cooling solution if not exotic cooling.
