Missing GPU sensor on MacBookPro 13 late 2013 (ME865)

[petrov]

now
- built-in GPU core DTS is absent in DTS list
- sensor-based value may not be hottest

I hope in the future release
+ sensor-based value=MAX(built-in GPU core, CPU core 0, CPU core 1, ...)

thanks

Please post technical information from the about dialog

As you can see, there's no GPU sensor supported on this macbook model.
GPU sensors are TG**

TCGC () - 39 - PECI GPU temperature sensor

Is there any proof link that TCGC stands for GPU?

BTW "PECI" stands for Platform Environment Control Interface

[petrov]

first proof

experiment
3D benchmark -> TCGC > TC0C,TC1C
pure CPU load -> TCGC < TC0C,TC1C


second proof

HWMonitorProfiles.m
https://searchcode.com/codesearch/view/49834040/
[NSArray arrayWithObjects:@"TCGC", @"PECI GPU", nil],
[NSArray arrayWithObjects:@"TCGc", @"PECI GPU", nil],

Thank you for the information. Will update it for the next release

[petrov]

Big thanks!
Please, do not forget, that one sensor does not provide an adequate value for the control, needed the maximum value of the group of sensors.

Please try the newest version 1.1.12.1 with PECI GPU sensor

[petrov]

Good job, but it's only half the problem.
