What am I doing wrong? Undervolting is bringing up my temperatures (pics included)

2019-10-08, 15:00 PM

Undervolting is bringing up my temps in almost all situations and I am unsure what is going on.

y540
17.3"
i7-9750h 2.60Ghz up to 4.50Ghz
16GB Ram
RTX 2660 

No change in ambient. Have gone back and forth between stock and -1.50v for the past few hours and consistently get higher temps on idle, stress test, and gaming.


Here are my latest findings.

 

These are all package temps

 

 

Stock

--------------------------------------------------------------

 

Idle

Around 45c for about 15 minutes, it then jumped up to close to around 48c for a few minutes before dropping down to 40-43c for several minutes. It then went back to around 45c. This was package temp , many of the cores are around 43c

 

Stress Test

AIDA64 + Heaven - Performance Mode - Began at 90-95c. Jumped around 94-96c for a few minutes before dropping to mid/high 80's (Around 88c) Starting to hit 90c at the 6 minute mark. Only throttled at the beginning before the fans were in full force. At around 16 minutes temps are reaching 91-94 degrees. It begins to throttle, but ever so slightly, like an occasional 3%. Cores around 3500-3600 Began to throttle consistently at the 24 minute mark as temps are around 93-95c

 

GPU - 74 at end of test

 

The end of the stress test for both -155.0 and stock were very similar, but build up under stock was much cooler and slower on stock

 

Cinebench - Around 86-87c after fans kicked in. Test result - 2858

 

Prime 95 Blend - Short test. High 70's

 

Gaming

Metro Exodus - Ultra - Ray Tracing - 65c

 

-155.0

--------------------------------------------------------------

 

Idle

Around 46c. Jumps to 48c more frequently than on stock.

 

Stress Test

AIDA64 + Heaven - Performance Mode - Began at 90-95c. Did see 97c briefely after 6 minutes where the temps mostly stuck around mid 90's (93-95) Maintained these temps for 25 minutes. Likely due to throttling which was mostly around 22-24%. Cores at 3500-3999Mhz

 

GPU - 78 at end of test

Cinebench - Around 88c after fans kicked in. Test result - 3154

 

Prime 95 Blend - Short test. Low 80's

 

Gaming

Metro Exodus - Ultra - Ray Tracing - 75c
