What is DRAM and how does it differ from RAM?

[ccdsg]

What does overvolting DRAM or RAM do as well, I have my RAM set to it’s clock speed (3200), and my XMP profile had the DRAM voltage set from 1.15 or something like that to 1.35v, could I do this?

DRAM (dynamic) uses capacitors and needs to constantly pulsed at a clock rate. SRAM (static) uses transistors.

 

as far as I know, sram is used in CPU caches and is much faster than dram, but the capacities are much lower and cost is higher.

 

overvolting lets you run the various timings faster at the expense of potentially more wear, more heat, and more power draw.

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.

Generally in a desktop setting RAM and DRAM are used interchangeably, so unless you're in an engineering lab assume that they're the same thing.

It can sometimes make it more stable or allow for you to run more aggressive speed/timings. There are times when that's not the case however, whether because the motherboard doesn't have optimizations made for high voltage training (the B660M-A Pro DDR4 in my experience memory overclocking on that board will get less stable with voltages above 1.45V with DIMMs that scale to over 2V), the memory is overheating, or the DIMMs don't scale with memory voltage (Samsung 8Gb C die on DDR4, for instance, gets less stable when running above 1.35V). 

 

Generally speaking, just let the XMP set the voltage, it should do a good enough job.

So I should just use the XMP profile that overvolts the DRAM the motherboard has already?

i wouldn't even consider 1.35v overvolting.

 

It's standard fare for 3200+
