At the end of last year, I was researching GPUs like a madman, trying to find the best option for price and performance and maybe also have some headroom for a future CPU upgrade. My starting point was a Ryzen 5 2600, 16 GB of 3000 MHz CL15 RAM and an AMD RX 570 with 8 GB of VRAM. A very good performance per buck machine in the summer of 2019 for 1080p gaming. It was purpose-built to be cheap with an upgrade path in the near future. However, my inner hardware enthusiast didn’t want to be content. It also didn’t help that the two games I was playing at that time performed rather poorly (which was the games fault, but you take every excuse you can get to buy new stuff).
Putting that aside, I have data of three graphics cards to compare, tested in four games at three different in-game settings – plus a custom one for two games that I used for playing. In addition to that, I have a bit of CPU overclocking as a result of troubleshooting and a RAM upgrade from a 3000 MHz CL15 kit to a 3600 MHz CL17 kit – which is running at 3400 MHz. More wasn’t possible with this motherboard and CPU. This post isn’t about the CPU overclocking though. I did that to see if the 5700 XT was limited by the R5 2600 and would perform better with a faster CPU. Well no surprise there, but as it turned out, the numbers I found were not caused by the CPU. More on that later.
Recently I set out to figure out how much clock speed I can squeeze out of my Zen+ based Ryzen 5 2600. To make life easier I figured I use Ryzen Master so I can change the settings while I’m in Windows so I don’t have to reboot every time I increase the clock speed. This has worked nicely until the point where I figured the viable maximum was. The next step was to dial those numbers "into hardware", meaning setting the options in the BIOS so that Ryzen Master is not required any more. And this is where my issues started to appear.
First, here’s a screenshot of the message Ryzen Master was giving me. After that I’ll explain what had happened.
In order to set the CPU multiplier you have to change from automatic to manual mode in Ryzen Master. I wanted to reset all options to their defaults after setting the overclock in the BIOS, but I always kept getting the message that Ryzen Master wants to restart Windows because the setting was changed to "Manual" – which it wasn’t, but more on that later. So I did as it asked multiple times with the same outcome every time. Effectively, I was doing a boot
So, how did I get there?
Find a stable overclock in Windows using Ryzen Master.
Reboot to BIOS and set the overclock closer to the hardware.
Reboot to Windows and reset everything in Ryzen Master.
Manual "Boot Loop" a few times.
Notice CPU always at 4GHz, no more Cool’n’Quiet operation mode.
Undo overclock in BIOS.
Still see overclock in Windows.
Uninstalling Ryzen Master.
Still see overclock in Windows.
Ryzen Master still not resetting.
Manual "Boot Loop" a few more times.
Getting pissed and searching the Internet – apparantly I was not alone.
More reboots and tests with BIOS settings.
It was the frickin’ BIOS! Ryzen Master was not to blame.
I have an ASRock B450 Gaming mITX mainboard with the latest non-Matisse (Ryzen 3000) BIOS. It is not recommended to upgrade unless a Ryzen 3000 is installed. There’s a weird bug in the BIOS that still applies the overclock even if the setting is set to "Auto by AMD CBS" (or something like that). There were two things that helped:
Load BIOS defaults.
Enable manual control and set the correct CPU base frequency at 3400MHz.
When applying the overclock with 4000MHz it effectly ran at 4GHz every time, even in idle. When setting 3400MHz it properly clocked down and also boosted as a R5 2600 should. The same setting only with a different clock value produced a different behavior. And unless the BIOS defaults are loaded the "Auto" mode doesn’t do what you expect – if you’ve set an overclock previously.
Curiously enough, booting Fedora Linux from an USB stick did properly scale the CPU frequency based on the load, even with the overclock applied. Apparently only Windows or AMD’s drivers didn’t manage to do that. Booting a Linux helped me to rule out Ryzen Master as the root of the always applied overclock although the BIOS setting was set to the default Auto mode.
Don’t overclock on this mainboard.
The OC options for the CPU are laughable at best. No way to set the multiplier per core.
Next time buy a higher-end mainboard for overclocking (ITX is expensive though…).
As mentioned in the Overclocking the Core i5 post a while back, my graphics card was limiting higher performance outputs, especially since it had to render games in 2560×1440. I hinted at an additional post dedicated to overclocking the GPU and this is it in some ways. I did overclock the GPU, but shortly after I also replaced it with a Gigabyte G1 Gaming GTX 1080. Nevertheless, for comparison, I will include the overclocked results based on the custom graphics settings from the last post and also compare it to the 1080 using default game presets. This way you can easily compare with your own rig. I had hoped I could also include Ryzen tests, but unfortunately Corsair’s AM4 mounting kit for the watercooler is still travelling around the world. So, there’ll be another performance related article (hopefully) soon. That one will compare the overclocked i5 with the GTX 1080 to a Ryzen 1700X with the 1080. Not only in games, but also in encoding.Read More »
Until a couple of months ago my main focus on buying input devices for computers was based on performance and price. I mean, in general that is how one goes about spending money, right? Check the spec sheet and see if it’s worth it. That’s how I always buy my things. I make up my mind that I need something and then I visit my preferred retailer websites and compare the prices. At my home desktop I am a bit more demanding than at work where I simply used (past tense) what came with the computer, but ergonomics never played a role. Boy has that changed. Read More »
My gaming PC is about two years old now (read this and this for more information) and although I didn’t really have any serious, permanent performance issues in games, I felt that it was about time to change something.
Here’s a short review and benchmark comparison of NVIDIA’s latest GTX 970 vs. the AMD Radeon HD 7870 (quite a mouthful) that I had installed before. The latter also had to show what it can do compared to an older NVIDIA GTX 560 Ti. Read More »
Recently I wanted to install a Gigabyte Radeon HD7870 in an older PC with an ASRock P67 Pro3 Mainboard. The surprise was big when the monitor didn’t show an image and the computer didn’t boot. Instead, the mainboard’s debug panel showed the error code 97. According to the manual this means “Console Output devices connect”. Not connectED but more likely in the process of initializing the graphics card and failing while doing that.
There’s an easy fix for that. Installing the latest BIOS version (3.30, installed at the time was 2.02) resolved the issue and the computer booted without problems.
