Raspberry Pi: Boot Loader
همین جوری که می دونید رسبری چیزی به اسم BIOS و اینا نداره برای همین تنظیماتش رو توی یه فایل توی این آدرس نکه میداره
کد:
/boot/config.txt
اون فایل رو پاک کنید یا به یه اسم دیگه ذخیره کنید.
اگه حالا رسبری رو روشن کنید تنظیمات پیش فرض رو خودش ایجاد می کنه ولی این جا من متن کاملی رو میزارم که تمامی تنظیماتی که میشه انجام داد رو توش ذکر کرده

##  Overclocking Settings
##
##  ARM, SDRAM and GPU each have their own PLLs and can have unrelated
##  frequencies.
##
##  The GPU core, h264, v3d and isp share a PLL, so need to have related
##  frequencies.
##  pll_freq = floor(2400 / (2 * core_freq)) * (2 * core_freq)
##  gpu_freq = pll_freq / [even number]
##
##  The effective gpu_freq is automatically rounded to nearest even integer, so
##  asking for core_freq = 500 and gpu_freq = 300 will result in divisor of
##  2000/300 = 6.666 => 6 and so 333.33MHz.
##

#over_voltage_sdram_p=0
حالا اگه تنظیمی رو میخواید تغییر بدید اون خط هایی که فقط یدونه # دارن رو باید # رو پاک کنید و مقدار مورد نظر رو از گزینه های قبلیش که توضیح داده انتخاب کنید.
توضیحش کامل هست من فقط بعضی هاش که نیاز به اطلاعات اضافی داره رو میگم
کد:
Licensed Codecs
ببینید رسبری ای نقابلیت رو داره که فرمت های مختلفی (همون هایی که ذکر شده) رو به صورت سخت افزاری دیکد کنه (پخش بشه) اکه این قابلیت پولی هست اگه فعال نباشه نرم افزاری انجام میشه و کمی کند هست
کد:
Overclocking Settings
سعی کنید از مد های پیش فرضش استفاده کنید(همون جا گفته چه مقدار هایی) چون این کلاک ها باید با هم هماهنگ باشن وگرنه کارایی پایین میاد از اون طرف رسبری از گارانتی خارج نمی شه بجز در چند مورد که باید مطالعه کنید که مهم ترینش زیاد کردن دمای خطری و افزایش ولتاژ از یه حد مشخص هست البته اون مود های مشخص مشکلی ایجاد نمی کنه
کد:
initial_turbo
این قابلیت هست که از زمان بوت تا حد اکثر 60 ثانیه به صورت حداکثری رسبری رو اورکلاک کرد که موجب میشه سیستم عامل سریع بالا بیاد این اوکلاک زمانی غیر فعال میشه که یا دما زیاد بشه یا زمانش تموم بشه یا سیستم عامل لود بشه و سرعت رو کنترل کنه
-
سرعت SD رو هم عوض نکنید چون توی فایل ها مشکل ایجاد میکنه.
اگه سوالی بود همین جابگید تا بیشتر توضیح بدم.
