Hemen konuya giriş yapalım...Bu bir powershell gerçek yönetim donanım katmanı müdahale betiğidir.Gerçek sistem (Windows11) ve donanımda (Lenovo Idepad Gaming 3) test edilmiştir.Sonuç olarak, "GEÇER" not almıştır, uygulayan tarafından...(TRWE_2012)
Dizüstü bilgisayarınızın işlemcisi bazen gereğinden fazla ısınıyor, fanlar gürültü yapıyor ya da bataryanız hızla tükeniyor mu? Bu betik, Windows'un yerleşik güç yönetim altyapısını (powercfg) kullanarak CPU'nuzun maksimum hızını saniyeler içinde GHz cinsinden sınırlamanıza olanak tanır.
Neden güvenli?
Bu bir aşırı hızlandırma (overclock) aracı değildir ,tam tersi. CPU'nun zaten fabrika tarafından desteklediği hız aralığının üst sınırını belirler, voltaj veya firmware'e hiç dokunmaz. İstediğiniz an tek tıkla temel hıza ya da tam performansa geri dönebilirsiniz; kalıcı hiçbir değişiklik veya risk yoktur.
Neden herkes için çalışır?
Betik hiçbir donanıma özel sabit değer içermez , açıldığında kendi CPU'nuzun temel hızını otomatik önerir, siz yalnızca Turbo Boost tavanınızı bir kez girersiniz. Intel, AMD, hangi model olursa olsun aynı mantıkla çalışır.
Üç basit buton, üç net sonuç:
1. Return to Base Speed : Günlük kullanım için sessiz, serin, düşük güç tüketimi
2 .Remove Limit (100%) : Oyun veya ağır iş yükü için tam performans
3. Apply Custom GHz : Kendi belirlediğiniz hassas bir tavan
Tek tık, sıfır risk, tam kontrol... Ve uzun ömürlü donanım parçası...
Ekran Görüntüsü : (Aşağıdakiler bana (donanıma özel betik ) görüntüleridir.
İkinci değer kutucuğuna sahip olduğunuz CPU'nun maksimum hızını (Turbo hız) yazın.
Üçüncü değer kutucuğuna sahip olduğunuz CPU'nuza kullanmak istediğiniz bir değeri (min-mak değerleri arasında bir değer) yazın.
Sonra, "Appy Custom GHz" butonuna basın...
Bu kadar.
Güle güle kullanın....
