How much power does a single 64gb ECC ddr4 module use?

[Bean Cooling]

I am building a system with 64gb ecc registered server ram and I need to know how much a single 64gb ecc registered ddr4 dimm uses, if anyone knows please let me know.

Extremely little.  Probably wattage in the single digits if I was to guess

Best I could find is 3-5 watts for DDR4, it doesn't use enough to bother accounting for most of the time.

Could I please have an estimation?

That was an estimation: less than 10W

I looked around and people are saying ~4 W for a DDR3 stick... I'd imagine DDR4 would be less, but then capacity has gone up so... maybe those balance out?  Point is it's not anything to worry about for cooling or PSU purposes.

Most DDR4 modules are 1.2-1.35V and pull about 1-2A making DDR4 use 2-4W per module. We're looking at wattage so low, that you can touch it without causing significant burns unless you electrocute yourself from bare traces.

"significant"? I'm pretty sure you could touch it without getting burns at all In fact I would bet that it won't even feel warm unless you are overclocked and working it hard.

Not to mention there is no way you could get electrocuted with voltage that low

You never know.

Well, I do because I just tried it and my description was accurate.  You can tell the metal is warmer than a plate left out in the middle of the room which feels cold by comparison, but it's what I would call skin temperature.  Not even warm, certainly not hot, and no way it can shock you.

I wouldn't think it would as there are usually layers of fiber over the traces and and the amperage and voltage aren't enough to cause nerves to fire through the resistance intact skin provides.
