When i check my processor details it lists it as an intel core i7 4500U @1.80GHz 2.39GHz.
As i understand it this model should Turbo boost up to 3GHz. Does anyone have a link to
the correct driver for this CPU?
I manually updated the driver to the latest one on the Intel website by installing the suggested
driver - INDOTH-00295906-0082. When I checked in Task Manager it gave me a maximum
speed reading of 2.39 GHz. I then went to the sony support site, found my model/OS Win 8.1,
and downloaded EP0000315972- CPPC Driver update. This changed the maximum speed to
1.80 GHz. I followed that by downloading and installing EP0000316566 - CPPC Driver (Intel)
It said-
What does it fix?
Replace Windows 8.1 upgrade driver.
Fix CPU turbo mode issue.
This made no discernible difference - the maximum speed stayed at 1.80 GHz.
Please see the attached screen shots for clarity. These were taken after all the steps above
