What is DRAM and how does it differ from RAM?
DRAM relies on capacitors and must be repeatedly charged at a specific clock speed. SRAM employs transistors and operates with quicker access times, though it stores less data and costs more. Overvolting allows faster operation but may increase wear, heat generation, and power consumption.
For consumer purposes it's all UDIMM DRAM, even if they don't state it. XMP is technically overclocking, which needs more voltage to get the speed and settings in the profile. That said, in practice, it's your normal operation. Don't worry about 1.35-1.4v on DDR4. If it boots on XMP without any stability issues, stop worrying about it. There's an XMP profile for a reason. Come back to us if it has problems. Otherwise, carry on.
Usually RAM and DRAM refer to the same components in a desktop setup, unless you're working in an engineering lab. This can enhance stability or enable faster performance settings. However, there are situations where this isn't true—like when the motherboard lacks optimizations for high-voltage training, causing memory instability at voltages above 1.45V with DIMMs that exceed 2V. In such cases, overheating or mismatched scaling can occur. Generally, allow XMP to handle voltage settings; it should manage things well.
