I'm on graphics driver version 10.18.15.4279 (Latest one as far as I'm aware)
I have fully uninstalled it, restarted and reinstalled it but that hasnt worked.
I have Windows 10 64 Bit
I'm Checking the frequency using two programmes :
Intel Extreme Tuning Utility (Latest Version) and HWMonitor by CPUID (also latest version)
Both of these programmes display the frequency in real time and they are both showing identical frequencies.
When on either "Maximum Battery Life" or "Balanced" power plans the frequency is at 948MHz/950MHZ around 95% of the time. It will very occasionally drop to 448MHz/450MHz when on battery saving (somewhere in between if on balanced) before going straight back up to 950MHz. This is irrespective of whether it is on AC Power or not.
sorry to reply to an old 3d, but i have the same issue:
My gpu always runs at 900mhz also when the system is idle (base clock should be 200 or 300 mhz).
My config is:
notebook HP 15-r225nl
cpu i5 5200u (with gpu intel hd 5500)
latest bios installed
latest intel video driver installed (220.127.116.1101 11/08/2016) after cleanig propely the old one
win 10 home x64 with all updates
I'm quite sure this issue occorred since the upgrade from win 8.1 to win 10.
In the bios there is no setting about video card profiles.
Intel driver options are set to default (balanced mode), but nothing changes going from max percofmance to battery saving or balanced.
can you help us? I would also ask davidjones141if he solved the issue.
Thanks a lot
