This issue accrued out of nowhere, it started 6 months after using my gpu i tried to format and reinstall drivers in many ways still the same issue remained (7001 mhz memory usage)without even running any games etc, i'm pretty desperate can anyone help me ?
Your case is normal. When the GPU is not needed it goes to low power states that downclocks itself. Both GPU clock and memory clock are lower and when an application needs more power, the GPU goes to normal advertised clocks/speeds.
In my case while idle I have a core clock of 139Mhz and memory clock of 810Mhz. When I open a game, core clock goes to ~2000Mhz and memory clock to 8010Mhz.
First when i got my gpu in idle mode it used to not get further than 1400 mhz memory usage, now in idle mode it's always at 7001 mhz even if 0 applications running it's stuck at 7001 mhz. I use the gpu software that's called EXPERTOOL , i even used msi after burner however i got same results.
