Ryzen 5800x Temperatures Spike When RAM Not In Use

[YosefSchmoesef]

Hi, All.

 

My system is a 5800x and 3080 RTX on an x570 Aorus Master mother board. I have been experimenting with various PBO, IF settings, and RAM, and running appropriate benchmarks to test stability and temperatures. With the Dark Rock Pro 4 cooler that I installed, I have become accustomed to seeing 85-90C temperatures on the 5800x under full synthetic load such as Cinebench. This forces the all core boost to cap out at around 4.55gHz. Today, I was trying to stress test my IF by running Folding at Home at Full Power on both CPU and GPU, and observed similar temperatures, and clocks on the processor under this load. After some time had elapsed, I opened OCCT to run a RAM test concurrently, and my heart sank as I immediately heard all the fans in my system ramp down. My panic however, was quickly replaced by a combination of bewilderment and excitement, as I watched the system not only continue on, but also the core clocks increase and temperatures plummet. All cores were now sustaining a 4.7gHz+ load while only at about 65C. I let it run for a while, no errors in OCCT, and progress on the folding tasks reflected the increased performance. Out of curiosity, I closed the OCCT RAM test, and immediately the CPU temps shot back up. Does anyone have any idea what could be going on here? Is this just IF instability, or perhaps a symptom of an admittedly early BIOS?

 

Thanks!

 

Edit: Some additional info. I have been running IF 1900 for about 2 months with no WHEA errors or other obvious signs of instability. The RAM is run 1:1 at 3800mHz CL 15 with tightened timings. BIOS is F32a.

Depending on how Windows prioritizes the programs and instructions sets, results and temps will vary when stressing with multiple programs.

 

You should just use one or the other honestly. But from what you describe, your system seems stable and sound.

Thank you, ShrimpBrime. You appear to be correct, and OCCT seems to be taking priority on all threads. Despite usage never dipping below 100% usage, these workloads obviously perform quite differently on the CPU. A little disappointing as I am still hopeful of getting this hothead 5800x under a little better control, but at least that clears up the confusion.

Good luck with getting it lower! When I get home from work in Feb I have to start playing with that. I knew the 5800x was going to be really hot going into it, but turns out they don't do well in some ITX cases.
