I am experiencing a problem with my AMD A8-4500M APU. It is rated to be able to run at 2.8 gHz, but I have only seen this speed once or twice, very briefly.
The clock speed changes depending on the power setting in Windows that I am using. On the max power setting, the highest I can get is approx 2.3gHz (100 x 23.0).
Note: computer is a laptop, model specified below.
I don't know how to get the APU to run at it's maximum capibilties. Can anyone help with this?
- AMD Radeon HD 7640G (integrated graphics)
AMD Catalyst Driver Version, and Driver History
- Windows 7 Home Premium SP1
- My APU dynamically clocks based on the power setting I am using in Windows. This can range anywhere from 0.8 gHz to 1.3gHz to 2.3 gHz at it's max. The APU is supposed to be able to go up to 2.8 gHz but in no way have I been able to achieve this on my own. I have seen it rise to 2.8 briefly only a few times - it is hard to say when this occurs, although I seem to remember it happening at the start of Windows once.
