PC losing performance after a few hours turned on
Here’s a rewritten version of the text, aiming for clarity and flow while preserving the original information:
“This document describes an issue I've been experiencing with my PC. For several hours after starting, games run smoothly on high graphics settings, often exceeding 100 frames per second. However, after extended use – typically after a few hours of gaming or general usage – performance degrades significantly. Games will lag, freeze intermittently, and occasionally my mouse freezes as well. Even simple applications like Twitter or YouTube can experience freezing issues.
I recently built this PC around the time Ryzen 3rd Gen processors were released, leading me to suspect that RAM might be the cause of these problems. The PC is relatively new and includes: a Ryzen 7 2700x CPU, an Asus Strix Gaming 2060 OC GPU, a BeQuiet Dark Rock 4 cooler, 16GB of DDR4 Vulcan RAM (1064Mhz), and a Corsair VS650 power supply.
Notably, as I type this response, the PC has frozen several times – highlighting the intermittent nature of the issue.”
This document provides instructions on how to diagnose potential overheating issues in a computer system. It outlines the steps involved in monitoring CPU and GPU temperatures under load, utilizing tools like HWMonitor or HWInfo64 for accurate data collection and reporting. The goal is to identify any thermal bottlenecks that may be contributing to performance problems.
My gut feeling is that it takes an hour or two for your internal case temp to get up to 30C+ at the bottom, but not warm enough to trigger it to turn off. Once you hit the rated max temp for your PSU it is not going to be able to power things as well. The lack of then reliable power distribution will mean performance will change by the second. One second you PSU is getting the full required wattage, the next it is getting less wattage which will lower performance.
How the hell is your RAM running at 1064Mhz? That is too slow. Have you checked if your XMP profile is running?
Edit: What speed is your RAM running at? Check your XMP settings in BIOS. Ideally Ryzen needs 3000Mhz to really come into element but 2666 is the bare minimum for it.
1064MHz would work out to DDR4-2133MHz. While slower than ideal, that is what a lot of 1st Gen Ryzen ran at with all 4 memory slots filled. That being said, RAM speed would be noticeable right away for performance drops.
Here’s a rewritten version of your text, aiming for clarity and flow:
“I'm experiencing persistent performance issues with my PC. Initially, I was having trouble with my RAM, which seemed to be running at a slower speed than its rated 2400MHz – ideally, 3000+ MHz would have been better. To address this, I diagnosed the problem using MemTest64 and ultimately resolved it by adjusting settings in my BIOS.
Since then, I’ve upgraded several components to try and improve performance: I replaced my old hard drive with a WD Blue 500GB NVMe SSD and upgraded my power supply unit (PSU) to a 2015 CX750. I also swapped out my RTX 2060 OC graphics card for an older GTX 960, updating the BIOS to version 5407 and reinstalling all drivers. I monitored temperatures closely while running demanding games like GTA, which consistently froze, but temps never exceeded 44°C.
Now, I suspect the issue might be with either my motherboard or CPU. Despite thorough testing, including MemTest64, I’m still struggling to pinpoint the root cause and achieve stable performance.”
