There is required info:
AMD Graphics Card: AMD Radeon HD 8850M 2GB
Laptop System: Dell Inspiron 15R 5537
Operating System: Windows 10 64bit (1703)
Driver version installed: AMD Catalyst 15.7
Display Device: 15.6 Full HD — 1920 x 1080 @60Hz
Motherboard: DELL Inspiron 15R 5537 Motherboard i7-4500U 3.0GHz CPU CD6V3 LA-9982P
CPU: intel i7-4500U
RAM: 8GB DDR3 SODIMM 1600Mhz
When using high-performance applications(or game, no matter what app it is, result is same) that is set in the catalyst control panel,
there is a problem with very weak performance. I checked it with the MSI afterburner and frequency is only 300 Mhz
instead of ~ 725 MHz. The laptops fan does not turn on and the graphics card temperature is ~ 46 ° C.
The locked frequency is 300 Mhz throughout the runtime.
I tried reinstalling the drivers for an older version (from dell support Video_Driver_6YKW1_WN32_15.201.1101_A01).
Occasionally it worked properly, and the apps and games were doing great until the computer was restarted.
I suspect that the problem might be in the driver for
Intel Management Engine Interface Driver (I have installed Chipset_Driver_KV645_WN_220.127.116.110_A02)
or Intel Chipset Driver (Chipset_Driver_FTHX8_WN_18.104.22.1686_A00). Both are from dell support page for my laptop.
I tried a clean installation with the updates turned off and it did not help.
Thank you for the advice.
