VRM on the new AM4 motherboards - Page 139

I can't compare to the other sections with "VR1" and "VR2" as I don't have them on this board, and I can't see all of yours either, just the first two. I know I have one choke that tends to run much hotter than the other 5, so I assume the associated 'fet for that phase is also higher. I could skew results by only pointing at the two coolest running phases if I wanted.

This is why I would like to take video using IR thermometer / touch test for a comparison. Can't really trust software. And I'm not saying you're doing any funny business either, orkin. Let me be clear on that. It's just that if we want to put all this argument spam to bed then we need some standard test that would be difficult to fudge.


The 51C is socket temp. smile.gif


My heatsinks are actually cooler than my body temp and feels cool to the touch.

Take the side off of your case and put a house fan on it if you want to compare.

Software is as accurate for my rig as it was for yours.

Pretty sure your vrm is running bellow ambient temps too...

I'm just being an idiot and did not want to break down the C6H....keep in mind my board is "prepped" traps more heat.

these chips really remind me of Llano. scale with cold not with volts but anyway.

IMC coldbug.........2933 insta fail......

not bad for a board I just put water on in a video.....still waiting for the water to kill it..getting grey hairs waiting.

Specifically waited for an 8K to complete.......it brings the heat.

Running prime my way of course ( the hard way )

You do realize that there are more important issues than reduced efficiency at low loads... not to mention that modern modulators take care of that anyway...

You do realize I completely clowned you and your condensation and moisture comments right?

Still waiting for an apology or at least an admission that you might have been wrong.

Sure, as soon as you quote where that was.

The... what?

What on Earth are you talking about?

 

 

Look - it's very simple.

 

More transistors=more gates.

More gates=more capacitors to charge.

More capacitors to charge=more electrons need to be taken from one place and put into another place.

More electrons that need to be taken from one place and put into another place=more losses.

cheers

I can go quote more where you claim its impossible to insulate properly to......suggesting hairs and other issues.

Sidenote Woot doing 4.3 now got vrm up to 35c @ 4.3, ill let prime cook for a while. Ambients are 76F currently.
