Minimal cinebench rating for R20 model at 3900x resolution and reduced clock speed [RESOLVED]
If it's any consolation (or not) I've already removed my 3950X with it stuck to the bottom of my Dark Rock Pro 4. I found it pretty funny though. Switch your PC on to heat the paste a bit before you remove it and give the cooler a little twist when you're ready to remove it.
It seems there’s confusion about the changes you made. The instructions were clear, but I didn’t fully grasp why the cooler was removed. Were you aiming for performance improvements or simply testing a different setup?
Another question appeared. After swapping the cooler and resetting BIOS settings, everything seems fine. You can enable the RAM XMP profile and set the interface to OC mode at a 1:1 ratio. Everything else should remain unchanged. Ram is 3600 MHz, IF is 1800 MHz—shouldn’t that be okay? Thanks, and sorry for any confusion.
Ensure XMP remains active; otherwise, you're likely running on limited memory and your IF should match 1:1. For a fresh cooler, it's best to keep other settings stocked, run Cinebench, collect metrics, then enable PBO + AutoOC to compare performance against the new temperatures.
Upgrading from a 3950X XD a few months back isn't enough for more RAM.
I'm completely new to building high-performance PCs. What I learned was that upgrades are like adding nice wheel rims to a car—just looks good. Before this, I had an i5 7400 (shitbox) and it struggled under heavy loads for hours, so these temperatures make me feel a bit uneasy. I didn't think CPUs could get that hot, or that stock fans would be so ineffective. They do the job, but they're really working hard.
The cooler arrived as promised. After removing the CPU, the BIOS reset to default settings. I turned on RAM overclocking to its maximum specs. Performance reached 100% utilization, hitting around 3.9 GHz under multithread stress. Cinebench R20 improved from about 5300 to high 6900 and occasionally surpassed 7000. Single-core speed remains solid at roughly 520. After a one-time Cinebench run, temperatures dropped to 76°C, then stabilized at 71°C after four minutes of testing—quieter operation. I updated the AMD Ryzen Power Plan (balanced) with the latest chipset driver. The change caused a slight (~100 pt) drop compared to Windows, but it's within acceptable range. Overall, I'm running cooler on a hotter system while gaining more performance. Thanks for all the advice!
