Frequently Asked Questions Like Best RAM, Power Plan Etc. About Ryzen 5000 CPUs Answered

AMD-Ryzen-5000-Zen-3-Based-CPUs-FAQs-Answered
AMD announced their Zen 3 based 4th Gen Ryzen 5000 CPUs on October 8th, 2020 and the CPUs went on sale on November 5th, 2020. Today we have a few questions answered about the Ryzen 5000 CPUs from the Senior Technical Marketing Manager at AMD, Robert Hallock himself. The questions that have been answered are applicable to all 4 CPUs - AMD Ryzen 5 5600X, AMD Ryzen 7 5800X, AMD Ryzen 9 5900X and AMD Ryzen 9 5950X - which are currently announced. Also whenever we mention Ryzen 5000 Series CPUs it applies to all said CPUs. So lets jump into the questions and their answers.
 

Q. Does Ryzen 5000 Need A Power Plan?

A. No, Ryzen 5000 Series CPUs do not need a Power Plan. (Source)

Q. Can Ryzen 5000 CPUs Reach 2000MHz FCLK?

A. Yes, good samples (silicon lottery) can clock to DDR4-4000 1:1. But the same is not guaranteed for all Ryzen 5000 CPUs meaning that few CPUs (lets say a Ryzen 5 5600X) can hit the 2000MHz FCLK but few others (lets say another Ryzen 5 5600X) cannot hit the 2000MHz clock - such CPUs might hit a wall at 1900MHz or 1800MHz FCLK. Upcoming AGESA BIOS updates will make this much easier. (Source)
 

Q. What Is The Best RAM Frequency For Ryzen 5000?

A. DRR4-4000. 2000MHz FCLK is possible with Ryzen 5000 CPUs but not all CPUs can do it. Robert Hallock stated and we quote: (Source)
2000MHz fclk is to Ryzen 5000 Series what 1900MHz fclk was to the Ryzen 3000 Series. Many samples can do it, but not all. In upcoming AGESAs, we will be implementing additional tuning that will make reaching 2000MHz easier. This is not a guarantee. There is no "safe bet" that your CPU will reach this frequency. But don't be surprised to see a bunch of people bringing that magical 2000MHz FCLK home with DDR4-4000.

Q. What Is The Best Price/Performance RAM Frequency?

A. DDR4-3600 is still the sweet spot for Ryzen 5000 Series CPUs continuing from Ryzen 3000 CPUs. Does this RAM offer best possible performance? No. Is is close? Yes. If your CPU can hit 2000MHz FCLK you can overclock your RAM to 4000MHz or 4000MT/s to gain more performance.

Q. Can You Tweak Ryzen Performance v/s Power With Windows 10 Power & Sleep Slider?

A. Yes you can tweak Ryzen performance v/s Power with Windows 10 power and sleep slider after you install the chipset driver. (Source)
 

Q. What Is The Best Memory On The Market To Pair With Ryzen 5000 CPUs?

A. DDR4-3600 or 3800MHz with tight timings. Though 2000MHz FCLK is possible it is not guaranteed on every sample so if you do have the CPU yet and want to buy a RAM kit for now that you can pair with the Ryzen 5000 CPU in the future then DDR4-3600 with tight timings is your best bet. If you have the CPU on hand and know that it can hit 2000MHz FCLK then you can try to overclock your already on hand RAM kit or if you have the means to upgrade your best bet would be DDR4-4000 kit.

Q. I have a DDR4-3200 Kit, Is It Not Enough?

A. It is enough. Though you can squeeze a little more performance out of the CPU with a faster kit, if you have a 3200MHz with tighter timings compared to a really loose 3600MHz kit, you may not be loosing a lot here. Though if you are willing to tinker around a bit, you can overclock your kit to squeeze a little more performance.

Q. Does Ryzen 5000 CPUs Have A New/Changed Memory Controller?

A. No. It is exactly the same as on the Zen 2 based Ryzen 3000 CPUs.

Q. I Have Ryzen 1000/2000/3000 CPUs Do I Need To Update To The New AGESA?

A. No. Stay on the BIOS you have (Source). But if you are upgrading from a previous gen Ryzen CPU to Ryzen 5000 and if your Motherboard does not have BIOS Flashback or Q-Flash functionality then you need to update your Motherboard BIOS to V2 1.0.0.8 or 1.1.0.0 and above using your old CPU for Ryzen 5000 support.

Q. What Are Normal Temperatures For Ryzen 5000 CPUs?

A.
Normal-Temperatures-For-AMD-Ryzen-5600X-5800X-5900X-5950X

As you can see in the image above AMD is stating that under full load with a mid-range cooler like a Hyper 212 your CPU can reach anywhere between ~70-85℃ where as with an entry level cooler like the in-box AMD Wraith Stealth cooler it can reach as high as ~80-95℃ before thermal throttling. If you are going to use 240mm AIO or a high end air cooler your CPU can heat anywhere between ~60-80℃ under full load.


Q. What Are Normal Voltage Numbers For Ryzen 5000 CPUs?

A.
Normal-Voltages-For-AMD-Ryzen-5600X-5800X-5900X-5950X

Under max boost your Ryzen 5000 CPU can take as high as 1.5Volts though it is to be noted that this Voltage of 1.5 Volts is not recommended for daily use overclocks. The 1.5V requirement of CPU is just for burst loads.

Q. Is Precision Boost 2 Automatic Overclocking?

A. No, Precision Boost 2 is not automatic overclocking. Robert Hallock stated and we quote: (Source)
Precision Boost is our boost technology. Every processor has a boost technology. But ours is unique that X Threads do not equal Y clocks. Why? Because that is slow.
It is to be noted that Precision Boost 2 is enabled by default on the AMD Ryzen 2000 and above CPUs.

Q. Is Precision Boost 2 Same As PBO or Precision Boost Overdrive?

A. No, Precision Boost 2 and PBO (Precision Boost Overdrive) are not the same thing. PBO or Precision Boost Overdrive is considered "Automatic Overclocking" by AMD. Where as Precision Boost 2 is a boost technology by AMD.

Q. Does Enabling Precision Boost 2 Void Warranty Of Your CPU?

A. No. Enabling Precision Boost 2 does not void warranty of your AMD Ryzen 5000 CPU. Precision Boost 2 is enabled by default out of the box by AMD. (Source)
 

Q. Does Enabling PBO or Precision Boost Overdrive Void Warranty Of Your CPU?

A. Yes, enabling PBO or Precision Boost Overdrive does void your AMD Ryzen 5000 Series CPU's warranty. This is applicable for any and all AMD CPUs. (Source)
 

Q. What About Undervolting The Ryzen 5000 CPUs?

A. Support for Undervolting Ryzen 5000 Series CPUs have temporarily been removed. Expect it to be back with upcoming AGESA BIOS updates with new functionalities. Robert Hallock said: "It's gonna be HYPE. Y'aint never seen Undervolting quite like this.". - To that time will tell.
