Question Overclocking AMD Ryzen 5500 on Gigabyte motherboard

[NisterOwO]

Hi, I'm a new user of Ryzen fammily CPUs. I'm planning to overclock it due to bigger requirements in CPU Power ( Exactly I need to provice more cpu power to my 25 virtual machines ). I already have experience in overclocking the AMD FX fammily processors when I entered the UEFI I was totally confused and not familiar in all these options. I'm sure I could learn all this stuff but the problem is I don't have enough time for this or this could take me more than a couple of days due to my schedule.

So I'm asking you guys for any tips or tutorials in the overclocking for AM4 platform, more thoroughly for 5th gen and for Gigabyte B550M DS3H motherboard. Also if you have the same CPU and motherboard as mine and you have done this before I'd like to see how did you handle with it

Below is the full spec of my PC:
- CPU: AMD Ryzen 5500 ( cooled with SilentiumPC Fortis 3 and five 140mm fans, the temperature has never went up 60°C)
- RAM: 2 x 32 GB Kingston KF3200C16D4/32GX and 2 x 8 GB Kingston KHX3333C16D4/8GX
- MOTHERBOARD: Gigabyte B550M DS3H
- GPU: AMD Radeon RX 570 8GB
- SSD M2: Lexar 240 GB
- SSD: Partriot P510 480 GB
- PSU: Silentium Vero M2 600W

MOTHERBOARD: Gigabyte B550M DS3H
What BIOS version are you on for your motherboard?

RAM: 2 x 32 GB Kingston KF3200C16D4/32GX and 2 x 8 GB Kingston KHX3333C16D4/8GX
You might want to work with one ram kit as opposed to mixing and matching ram kits. That being said, you should've looked into getting a DDR4-3600MHz dual channel ram kit. With one ram kit, namely the 2x32GB kit, enable X.M.P or manually input the ram's stickered info in BIOS(D.O.C.P).

Conventional fixed frequency all-core overclocking Ryzen CPU's is not usually productive because of how effective the boost algorithm is at safely hitting very high boost clocks, which also requires use of a high Vcore (up to 1.5V) to be stable. The boost algorithm, which keeps the processor safe from degradation and damage, is taken completely out of the picture when you use fixed frequency so you either use a dangerously high voltage continuously to remain stable or have to settle for a clock that is lower than the maximum boost clock.

There are two ways to get more performance out of the processor. One is to use PBO2 and Curve Optimizer to undervolt each core individually in a way the works with the boost algorithm. The other is to use extremely good cooling that keeps processor temperature under 80C in maximum loaded conditions, such as a Cinebench rendering. Using both of these together gives best results of all.

If you insist on fixed all-core overclocking try to use a VCore around 1.25-1.3V maximum and no more than medium LLC setting. Then find the highest clock frequency that remains stable at your desired workload. The closer to 1.2V you can get is safest if you intend to run heavy processing workloads; anything above 1.3V with a "barely stable" clock is probably degrading at a rapid rate when running very heavy workloads such as video rendering unless you can keep temperature in the 60's or low 70's. Which isn't likely unless using sub-ambient cooling.

BTW, 5000 series CPU's are 4th gen Ryzen as there are no 4000 series desktop CPU's. 5th gen Ryzen are the 7000 series CPU's that operate on AM5 motherboards.

The bios version is the newest one. I also forgot to mention that the motherboard Rev is 1.4. The X.M.P profile was already launched with 3200 MhZ frequency.

I found some free time to have fun with the stuff. While I was searching for some tutorials I found this guy's video

View: https://www.youtube.com/watch?v=RD51wAbmPvo
. I just followed the same settings as his ( 1.352 Voltage for core, 45x multiplier and discabled core boost option) and started benchmarking and testing the stability. I need to mention that in the beggining I disconnected two 8 GB ram sticks and left these with bigger capacity.

The tests went successfully. At the beggining I launched the performance test from Passmark. The results are in attached links.

It's strange that these memory sticks performed worse. However I made it to achieve 10% performance boost for CPU compared to the Passmark database and 8% compared to CPU-Z benchmark. The disturbing things were the temperatures while benchmarking. In CPU-Z Stress test for 10 minutes the Package and the Cores temperatures didn't reach much higher than 72 Celsius. Whereas while CPU benchmark in Passmark the Core sensor showed 82 Celsius for a few seconds.

After the benchmarking I went to stress testes. I started with only CPU test via OCCT Program.

Everything went well without any errors and the CPU didn't throothled. I noticed that the CPU VDD Voltage was mostly at 1.3V instead of 1.35V ( maybe VRM overloaded? ) and sometimes the Cores sensor showed +10 Celsiuses just for a second, then it dropped down ( maybe sensor error? ). The average temperatures were fine but surely this was a stop border for further voltage/clock increasing.

Then I tried to launch a Power stress test but unfortunately my hardware shutted down immediatelly
The reasons was the PSU which couldn't handle +5V so I had to remove some USB devices and disconnect DVD drive. I runned it again and temperatures went up to 90 degrees just in few seconds that my fans didn't have enough time to gain speed so I gave up the test.

I also runned one more test to check RAM performance for mixed sticks. The CPU was 1,5% slower and RAM was around 8% slower than after the previous OC.

Anyway I tested the hardware in the field I'm going to need and it handles the temperatures well with 80~90% CPU usage but I'm surely gonna try to undervolt it in the future.

For ryzen 5000-7000 series Curve optimizer is a must have.
You can do it manually but expect HOURS of tweeking.
Part of Ryzem Master.
It is not perfect .but let it run and do its thing. Do the per core and all core tests.
When it gets its results for each test write it down.
Now go into bios and set 1 or 2 settings below what it suggests
If you get 20 on all core set it to 18 or so. Every processor is different.
Forget about old style overclocking. Processors are different now.
UNDERVOLTING and KEEPING IT COOLED is king.
It will boost itself if temperatures and power are kept in check.

Well, you're trying out fixed OC which is fine but do also try out PBO2 and Curve Optimizer is strongly suggested before settling on anything for long-term use. There are several youtube videos on how it's done. It doesn't have to take hours of tweaking (there's a process) to find a lower voltage for each core but it certainly can if you want to find absolute limits.

But whatever you do don't compare based on clocks alone; use benchmark results. Passmark is probably quite good but it's not as widely used as something much more simple: Cinebench. It's fairly short to run and yet has highly repeatable results. But what's more it's not a purely synthetic bench but much more reflective of real-world performance since it uses a production rendering application to render a scene. Also, it's widely used so you can compare results with others.

If you find bottom-line performance is the same or very little difference between fixed clock OC and PBO2/CO then you'll have to decide if it's worth burning up your processor using the fixed or going for longer life letting the boost algorithm do it's thing to keep it within FIT projections.

And when letting the CPU use it's boost algorithm (PBO2/Curve Optimzer) it's going to be very dynamic with constant and frequent clock changes on a per-core basis. It will only boost a core when it's needed so you might not think clock is high with PBO2/CO but it still performs very well in BM's.

And don't think of it as "throttling" when clocks are low; that occurrs only when something very bad happens such as when the CPU overheats significantly (around 105C if I'm not wrong) or the VRM overheats (usually around 115C on the FET's). You have to forget about anything you've known before as this is nothing like Intel CPU's, nor previous AMD such as Bulldozer or Phenom series.

And lastly: don't search for a stable memory overclock at the same time you're looking for a stable CPU OC. Do one at a time. This part of good OC technique is really no different from any generation or make of CPU, of course.
