A question about RAM

[Japsert]

Hi there! I'm kind of new in hardware stuff, so I'm sorry if this is a stupid question;
Does more RAM require more power? If so, a lot?

I'm probably going to upgrade from 8GB to 16GB, but my dad said we already use a lot of power. Will it matter?

It would only use a very small amount more basically nothing compared to other pc components. It is worth the upgrade depending on how much ram you use and what you are using your pc for. So tell your dad that it won’t add to the electricity bill.

No lol 

It doesn't 

Voltage will only matter if you enable xmp / push the ram to its advertised speed 

Ddr4 normally runs at 1.2 

Adding more ram simply will mean that two sticks will run at a certain voltage 

Ram barely consumes "power" so don't worry about that 

[Japsert]

Alrighto, thanks

In the over all scheme of things there are basically just a couple of energy hogs in your system and the systems ram is not one of them.  You won't notice a difference in the electric bill.

Quick question

What cpu ? And what is the ram advertised at ? 

What cl latency ?

Here's a quote from Crucial's website:

"The answer can vary depending on different circumstances, for example,  system type, applications, and the type of specific memory installed. For these reasons, we do not advertise specific power usage for any of our memory. As a rule of thumb, however, you want to allocate around 3 watts of power for every 8GB of DDR3 or DDR4 memory."

So according to them every 8GB of ram uses about 3 watts or power.

  The 24 gb gddr6 x of the rtx 3090 are rumored to consume 40 watts

According to Igor’s lab

I've got an Intel i7, I'm not sure what new sticks I'm getting or where from.

Vram has way more bandwidth that's normal for it to consume more power

Well if you want 

If it doesn't have a legacy bios you should enable xmp 

Essentially ram runs at a certain frequency out of the box usually 2400 or 2133 go to xmp and run it 

It will "over clock" the ram and it will run at it's advertised speeds so like 3200 or 3000 etc that will increase the performance as the latency will decrease 

The imc will have to do more work but Intel's imc (integrated memory controller) is pretty good so it should handle it 

Good luck

I know
