当我年轻的时候，我父亲会告诉我，“如果你要做某事，你最好了解所有的事实”。超频 CPU(Overclocking your CPU)也不例外。
从散热解决方案到电源，超频时需要考虑到计算机的每个组件。了解在此过程中将使用哪种散热器非常重要，因为有些散热器比其他散热器更适合此过程。
1500x 的备用散热器是Wraith Spire，它是一个 95 瓦的冷却器，而之前的Ryzen型号只提供一个 65 瓦的冷却器。Spire将允许我们超频到推荐的最大值，甚至更多。让我们开始。
在我们开始超频之前，安装CPU-Z和Cinebench很重要。这将向我们展示我们的超频是否实际上在所选时钟比率下稳定，并将显示相对CPU性能提升。
最初运行(Run)基准以查看CPU的默认状态并将这些值与后续基准进行比较。此外，使用工具来监控整个 CPU 的温度(monitor the temperature of your CPU )。
超频 AMD 锐龙 CPU
我们要做的第一件事是在计算机启动时按F2启动(F2)BIOS 。加载到BIOS后，您将看到类似于此的屏幕：
我们需要关注的唯一选项卡是MIT（主板智能(Motherboard Intelligent Tweaker)调整器）选项卡。在此选项卡中，我们将主要在高级频率设置(Advanced Frequency Settings)、高级电压设置(Advanced Voltage Settings)和智能风扇 5 设置(Smart Fan 5 Settings)中工作。
单击高级频率设置(Advanced Frequency Settings)将带您进入此屏幕：
这一点取决于您的配置，但AMD已表示推荐的超频时钟频率为 3.70 GHz，因此我们将其设置为此时钟频率。
为此，请选择CPU Clock Ratio并将其从Auto更改为37.00（对于我的构建，我已将其设置为39.00，因为这是我能够运行的最高稳定时钟频率）。调整时钟比率后，您会看到BIOS 倍频器(BIOS multiplier)自动将CPU 频率(CPU Frequency)更改为 3.7 GHz。
在启动之前，进入Advanced CPU Core Settings（在CPU Frequency下方）。您的屏幕应如下所示：
在此设置下，我们将Core Performance Boost设置为Disabled。这将防止频率波动，确保它保持在恒定的 3.7 GHz。接下来(Next)，我们将禁用AMD (Disable )Cool&Quiet 功能(AMD Cool&Quiet function )并禁用(Disable)全局 C 状态控制(Global C-state Control)。
接下来，我们将禁用AMD (Disable )Cool&Quiet 功能(AMD Cool&Quiet function )并禁用(Disable)全局 C 状态控制(Global C-state Control)。Cool & Quiet只是限制风扇速度，而C 状态控制基本上会在它认为处理器空闲时向您的(C-state Control)CPU发送命令以减少功耗，因为我们不想限制功率或风扇速度，我们将禁用它们。将SMT Mode(SMT Mode)、Downcore Control和Opcache Control保留为默认设置。
按F10保存设置并退出以将计算机重新引导至Windows并运行基准测试。注意：您的主板在修改设置后可能会循环开关几次，这是正常的。如果它关闭和关闭超过六次，它将提示您超频失败并引导您返回BIOS。
如果您的计算机无法以 3.7 GHz的时钟频率启动，或者您已经转到更高的频率（3.9 GHz），您将不得不提高CPU核心电压。要修改电压，请转到高级电压设置(Advanced Voltage Settings)，该设置位于高级频率设置(Advanced Frequency Settings)选项卡下。您的屏幕应如下所示：
高级电压设置(Advanced Voltage Settings)将使我们能够在更高频率下保持CPU
稳定(CPU)，但我们只会在需要时调整这些设置。增加电压也会增加CPU产生的热量，因此我们将在最后一次执行此操作，并且仅在超频无法在默认电压下工作的情况下进行。
在 3.7 GHZ时，您可能不需要增加电压，但如果需要，请进入CPU Vcore设置。AMD已声明推荐的最大CPU核心电压为1.4250 V，但对于我的构建，我试图让我的CPU尽可能保持凉爽。将此设置为1.4000 V就可以了。
我个人建议将所有其他电压保持在“自动”(Auto)状态，但如果您需要增加电压，则应匹配屏幕右侧的电压。这是一个例子：
- VCORE SOC不高于1.10000V
- CPU VDD18不高于1.800V
- CPU VDDP设置为正常(Normal)
- DRAM电压(DRAM Voltage)不高于1.200V
- DDRVPP电压(DDRVPP Voltage)不高于2.500V
- DRAM 端接(DRAM Termination)不高于0.600V
- CPU Vcore Loadline Calibration不高于Turbo
- VAXG Loadline Calibration不高于Turbo
重新启动并运行基准测试。
此时您的机器将有一个稳定的超频，但您的 CPU 可能运行有点热。请记住(Remember)，增加核心电压会增加产生的热量。
这就是风扇速度发挥作用的地方。在MIT(M.I.T)选项卡底部选择Smart Fan 5 Settings后，您的屏幕应如下所示：
如果此时您的处理器运行过热，请选择CPU Fan Speed Control并将其设置为Full Speed。保存您的设置并运行基准测试。
在运行了我所有的基准测试后，我的CPU性能提升了 12%，这可能看起来微不足道，但可能会影响某些应用程序的性能。您的CPU现在可以使用了。如果您有任何问题随时问！

How to Overclock your Ryzen 5 1500x CPU (Gigabyte Motherboard)
When I was young, my father would tell me, “If you’re going to do something, you bettеr know all the factѕ”. Overclocking your CPU is no different.
From cooling solution to power supply, each component of your computer needs to be taken into account when overclocking. It’s very important to know what kind of heatsink you’re going to be using during this process, as some will be better for this process than others.
The stock heatsink for the 1500x is the Wraith Spire, which is a 95 watt cooler compared to previous Ryzen models, which only provided a 65 watt cooler. The Spire will allow us to overclock to the recommended maximum and perhaps more. Let’s begin.
Before we start overclocking, it’s important to install CPU-Z and Cinebench. This will show us if our overclock is actually stable at the selected clock ratio and will show the relative CPU performance increase.
Run benchmarks initially to see the default state of your CPU and compare those values to subsequent benchmarks. Also, use a tool to monitor the temperature of your CPU throughout.
Overclock AMD Ryzen CPU
The
first thing we’re going to do is boot up the BIOS by pressing F2 when
the computer starts up. After loading into the BIOS, you will see a screen
similar to this:
The only tab that we need to focus on is the M.I.T (Motherboard Intelligent Tweaker) tab. Within this tab, we are primarily going to be working in Advanced Frequency Settings, Advanced Voltage Settings and Smart Fan 5 Settings.
Clicking
on Advanced Frequency Settings will
bring you to this screen:
This point depends on your configuration, but AMD has stated that the recommended clock ratio for overclocking is 3.70 GHz, so we’re going to set it to this clock rate.
To do so select CPU Clock Ratio and change it from Auto to 37.00 (for my build I have set this to 39.00 because that’s the highest stable clock rate I’m able to run). After adjusting the clock ratio, you’ll see that the BIOS multiplier automatically changes the CPU Frequency to 3.7 GHz.
Before
booting, go into Advanced CPU Core
Settings (right under CPU Frequency). Your screen should look something
like this:
Under this setting we’re going to set Core Performance Boost to Disabled. This will prevent the frequency from fluctuating, ensuring that it stays at a constant 3.7 GHz. Next, we’re going to Disable the AMD Cool&Quiet function and Disable the Global C-state Control.
Next, we’re going to Disable the AMD Cool&Quiet function and Disable the Global C-state Control. Cool&Quiet simply limits fan speed and C-state Control basically sends a command to your CPU to use less power when it thinks the processor is idle, since we don’t want to limit the power or fan speed, we’re going to disable them. Leave SMT Mode, Downcore Control and Opcache Control at their Default settings.
Hit F10 to save settings and quit to boot your computer back into Windows and run your benchmarks. NOTE: Your motherboard might cycle on and off a few times after modifying settings, this is normal. If it shuts on and off more than six times, it will prompt you with a message that the overclock failed and will direct you back to the BIOS.
If your computer failed to start at the 3.7 GHz clock ratio or if you’ve gone to a higher frequency (3.9 GHz), you’re going to have to increase the CPU core voltages. To modify voltages, go to the Advanced Voltage Settings, which can be found under the Advanced Frequency Settings tab. Your screen should look something like this:
The
Advanced Voltage Settings will allow
us to keep the CPU stable at higher frequencies but we’re only going to adjust
these settings if we need to. Increasing the voltage will also increase the
heat that the CPU will produce so we’re going to do this last and only if the
overclock doesn’t work at the default voltage.
At 3.7 GHZ, you probably will not need to increase the voltages, but if you do, go into the CPU Vcore settings. AMD has stated the maximum recommended CPU core voltage is 1.4250 V,but for my build I am trying to keep my CPU as cool as possible. Setting this to 1.4000 V will do the trick just fine.
I
personally recommend keeping all of the other voltages on Auto but if you need to increase yours, you should match the
voltages on the right side of the screen. Here’s an Example:
- VCORE SOC no higher than 1.10000V
- CPU VDD18 no higher than 1.800V
- CPU VDDP set to Normal
- DRAM Voltage no higher than 1.200V
- DDRVPP Voltage no higher than 2.500V
- DRAM Termination no higher than 0.600V
- CPU Vcore Loadline Calibration no higher than Turbo
- VAXG Loadline Calibration no higher than Turbo
Reboot and run benchmarks.
At this point you will have a stable overclock for your machine, but your CPU might be running a little hot. Remember, increasing core voltages will increase the amount of heat produced.
This is where the fan speed comes into play. After selecting Smart Fan 5 Settings at the bottom of the M.I.T tab, your screen should look like this:
If your processor is running too hot at this point, select the CPU Fan Speed Control and set it to Full Speed. Save your settings and run benchmarks.
After running all of my benchmarks, my CPU saw an 12% performance increase, which may seem insignificant, but can make or break the performance of some applications. Your CPU is now ready for use. If you have any questions, feel free to ask!
