Overclocking potential varies from chip to chip. The average Ryzen 7 2700X should be able to attain an overclock in the range of 4.1 GHz to 4.2 GHz, while the really good samples can reach 4.3 GHz to 4.4 GHz. It's a matter of winning the silicon lottery.
No need to actually overclock the Ryzen 7 2700X because of 2nd Gen AMD Ryzen™ Processors: Extended Frequency Range (XFR)2 and Precision Boost Overdrive (PBO) 2 will allow CPU processor to dramatically increase clockspeeds when the CPU has electrical, thermal, and/or utilization headroom to spare and is capable of reaching 4350Mhz on single core.
If you would like to try some manual overclocking you will get lock ups/blue screens and just plain old strange behavior with your computer overall.I can try to help you out if you want to try.
First things first you need to update BIOS and AMD Chip set drivers.You must have good cooling to achieve good overclocks.Enjoy have fun.
1. Download -AMD Chipset Driver
Version 18.50.16.01 For your Windows 10 version
2.Extract and Run setup.exe
3.Restart your computer
4.Download- BIOS 7B79v19
Release Date 2019-03-08
5.Extract and copy file -E7B79AMS.190 to thumb drive
6.Restart computer and go into BIOS
7.Put thumb drive with file E7B79AMS.190 on it in USB port.
8.Select M-FLASH in BIOS settings and reboot computer,it should do it all by itself.
9.Once rebooted in to M-Flash select file E7B79AMS.190 on the thumb drive and let the M-flash reboot computer .
10.Once back into BIOS setup your BIOS again (I included BIOS setting to try in download link below,also set fan profile in BIOS see below for settings,reboot computer to desktop).
11. It is a good Idea but not necessary to reinstall graphics driver and reboot computer.
12.BIOS settings I use are for a rough idea on what and how to set for proper voltages.Since these BIOS settings are for the 2600X you will need more CPU Voltage for the 2700X.
13.Now it is up to you where you start and what speed you want to achieve but the settings I laid out for all core overclock should be a starting point.If you reboot computer and get a crash of any kind,adjust CPU voltage by increments of +0.125mv until computer boots and run stress test for stability.
14.Also with your Ram you should just use XMP profile (if possible)because I have no clue what Ram you have.
15.Test computer with various test of you choosing for stability but AIDA64 Stress test are very good.Video game can expose bad overclocks on CPU and memory such as BIOWARE Anthem/Witcher3 .Memtest using 1usmus TM5 0.12 v3 config
Fan Settings in BIOS for overclock adjust as you want.
40% fan speed at 45c
45% fan speed at 55c
65% fan speed at 65c
100% fan speed at 80c
Download for all BIOS settings to adjust for manual overclock
