"Core Temp" - Official Developer Thread.

[DrMrLordX]

First time trying CoreTemp on my 3900x. It shows really high voltages compared to any other monitoring program. Temps are the same so I'm not concerned. Just seems a little weird.

Note that Core Temp reports VID rather than the actual vcore.
It could be the "observer effect", as the CPU clocks up when Core Temp polls it.
It's also possible that the VID is interpreted incorrectly, since I don't have any documentation for the 3rd gen chips yet.

Hmm okay, interesting. I have noticed that the reported VID fluctuates though, which is really weird.

I think that these chips are so dynamic and quick in the way they clock up/down, it's not really that strange.
I'm still trying to decide whether I should get the 3900X or 3950X when that one ships, so I don't have my 3rd gen CPU yet to see how it behaves myself.

 

[DrMrLordX]

I would say get the 3950X. Supplies of the 3900x have been so bad that it's hard to get one of those anyway.

Hey thanks for the update, but the page still lists version 1.14 and I cannot find where to find the 1.15.

https://www.alcpu.com/CoreTemp/php/download.php?id=3

for standalone or

https://www.alcpu.com/CoreTemp/Core-Temp-setup.exe

for the installer version.

It's probably a problem with cache in your browser. Press Ctrl+F5 to clear cache and reload the Core Temp page.

 

[Shmee]

Hmm, possibly. Anyway I dled the latest one, 1.15 from lordx's link. Thanks!

[DrMrLordX]

Meteor Lake support? Hmm!

By the way: the fact that you're still supporting Banias is awesome.

 

[The Coolest]

Thanks.
I'll just say that "support" is a strong word when it comes to Meteor Lake, but if Intel keeps things the same, as it has for years now, it should be able to run and give us basic readings like frequency, VID, temperatures and power consumption.

Banias is only really supported for identification, as it doesn't have the type of built-in thermal sensor Core Temp normally uses. But a user reported that the previous version crashed on his machine, and I found a really old bug.

Amazing this code base can almost vote!

Amazing this code base can almost vote!

LOL! And I've been using it about that long. Great little utility!

@The Coolest

I had decided to give this thread a sticky as its probably the majority go to software for CPU temp.
