Turbo boost ne s'active pas

[Polo2475]

Bonjour,

j'ai un ordinateur portable avec un i5 9300h, un Lenovo légion 5 (Y540-15IRH-PG0), avec dernier BIOS, Windows 11, les dernières mises à jour d'installer, tous les derniers drivers sont installés, aucun mode d'économie d'énergie n'est activé, les performances sont optimales, quand je lance un jeu tout fonctionne bien, le CPU monte à 4.00Ghz, mais quand je lance n'importe quelle autre application notamment des benchmarks, le processeur reste à sa fréquence de base (2.40Ghz).

Je ne sais pas pourquoi et je ne sais pas s'il existe une solution...

Merci à vous.

Hi, Polo2475.

Thank you for posting in our Community. I understand that your Intel i5-9300H isn't activating Turbo Boost outside of gaming, even in benchmarking applications, despite having the latest BIOS, drivers, and Windows updates installed. I see that you have a laptop. Since you're using a Lenovo Legion 5, please keep in mind that as an OEM device, there may be system-specific customizations, settings, and drivers that we’re not fully familiar with. That said, I’ll do my best to assist you and help find a solution to your concern. Let’s go through some checks to identify the cause.

• Can you confirm if Intel Turbo Boost Technology is enabled in the BIOS?
• What is your Windows Power Plan set to? (Check under Control Panel > Power Options and ensure it’s set to "High Performance" or "Ultimate Performance.")
• Are there any power limits (PL1/PL2) restricting Turbo Boost? Tools like ThrottleStop or Intel XTU can help check this.
• Which benchmarking tools have you tested? (Some may not fully stress the CPU.)

Have a nice day!

Best regards,

Von M.

Bonjour,

Oui, je prend le temps de vous répondre, alors tout les paramètres Windows sont bons concernant les hautes performances, tous les paramètres du BIOS sont également bien réglés… j'ai remarqué que quant le PC vient de s'allumer, dès que je le débranche et rebranche en l'espace de 5 mins, le boost est bien fonctionnel,  mais se rebloque à 2.40Ghz, le processeur tourne toujours à 2.40Ghz il ne se met même pas en repos à une fréquence inferieur sauf si je le débranche et rebranche encore une fois seulement quelques minutes avant de retomber encore à 2.40Ghz, rien n'est indiqué sur le support Lenovo, et le dernier Bios en date est de 2022...

Hello, Polo2475.

Common issues with Intel® Core™ processors not reaching their maximum Turbo Boost frequency include: The processor frequency is lower than the Turbo Boost frequency specified on the Product Specifications page, and inconsistent performance may occur, particularly when running non-gaming applications. Processors do not always run at their maximum frequency; they adjust automatically based on workload demands. When the workload is high and there are no physical limitations, the processor may operate at or near its turbo frequency. 

To ensure optimal performance, consider the following:

• Verify that your system is not experiencing physical constraints that could prevent the processor from reaching its maximum turbo frequency. Power delivery and thermal limitations are common examples of such constraints.
• Ensure that the thermal cooling solution for your processor is adequate, particularly for self-built systems.
• Check that the processor’s power limits (PL1, PL2) are configured to allow the processor to reach its maximum turbo boost frequency. For guidance, contact your system vendor.
• Confirm that your BIOS is up to date or reset it to default settings.
• Ensure that the Turbo option (if available in the BIOS) is enabled. It is typically enabled by default, but consult your motherboard/BIOS manufacturer for instructions on how to enable it if necessary.
