The OP didn't mention whether the CPU always runs at 790 MHz (.79 GHz) or only when it warms up. I know this was an old question, but my answer could be helpful to people searching for a similar issue.

But doesn't allow your PC to run higher than 800 Mhz speed with this message hidden. The fun fact about all this situation is that Dell allows you to disable that message forever on 1st event occuring at the boot screen, just hitting the F3 key (can be re-enabled in bios later). There you can find "the AC power adapter type cannot be determined.blah blah" event. To verify the reason, simply go to BIOS, the "System Logs"->"BIOS Events" tab. I made 90W of power available for system instead of 65W out-of-the-box and OptiPlex returned me insane 800 Mhz of power as reply to this. While giving me same issue you've described above on 7050 micro system. It came with 7.4->4.5 adapter and both are perfectly working on Vostro 14 5459. I've tried to use slim LA90PM130 90W adapter from my XPS laptop instead of OptiPlex's 7050 65W 0MGJN9. Even genuine Dell's adapter can lead to such issue. Problem with DC jack on the motherboard (loosened, unsoldered etc.) ģ.
Problem with AC adapter (center pin wire is broken, or pin was simply bent inside the jack), or dead Dallas 2501/2502 identify IC inside the adapter (common situation after charging HP laptop using Dell's charger - HP systems pulls 19V to that pin) Ģ. Is build-in to many Dell's products including laptops - you can easily find threads of XPS laptop users faced to same problems.ġ. BIOS will decrease the CPU mulitplier to 8x with FSB 100 Mhz and get stuck on this value. For example, if you're using non-genuine adapter. Called "the system will adjust the performance to match the power available". It's due to problem with your AC adapter. Intel® Turbo Boost Technology frequency varies depending on workload, hardware, software, and overall system configuration.ĭue to varying power characteristics, processors with Intel® Turbo Boost Technology will not achieve maximum turbo frequencies when running heavy workloads and using multiple cores concurrently.Īvailability and frequency upside of Intel® Turbo Boost Technology state depends upon a number of factors including, but not limited to, the following: Maximum turbo frequency indicates the highest possible frequency achievable when conditions allow the processor to enter turbo mode. EIST was introduced as a means of enabling high performance while meeting the energy star power-saving needs of a computer system.

And other software like HWmonitor routinely gets that number wrong and its not supported by Microsoft or Intel or Dell.Įnhanced Intel SpeedStep Technology (EIST) is a power and thermal management technology developed by Intel.
