Hi *,
I would like to share my experience regarding the issue mentioned above.
I have an older Dell OptiPlex 9020 with the following configuration:
- Intel Core i7 4770 @ 3.40GHz (original)
- 0PC5F7 motherboard (Q87 chipset, original)
- 32 GB of DDR3 RAM (2x SK Hynix HMT41GU6MFR8C-PB, original, and 2x Micron Technology 16JTF1G64AZ-1G6E1)
- Western Digital WDS100T2B0A-00SM50 SSD
- HL-DT-ST DVD+-RW GHB0N optical drive (original)
- AMD Radeon HD 8550 OEM GPU (original)
Despite its age, this PC still performs well for many tasks. A week ago, I decided to do a budget upgrade. Among various YouTube videos, the "2020 Dell Optiplex GPU Upgrade Guide" by RA Visuals was particularly helpful. After researching the market for used GPUs, I purchased a used Nvidia GTX 1650 Super. It arrived a day ago, and I installed it in my PC, powering it with a SATA to 6+2 Pin Power Cable (as recommended in the video). Initially, everything seemed fine. I installed the latest drivers from Nvidia (version 555.99) and noticed that the CPU cooler was running at high RPMs and became noisy.
In its original configuration with the AMD GPU, it was relatively quiet. Additionally, I encountered some user permission issues in Windows 10 Pro, which led me to the event viewer and the error mentioned in this topic.
I tried various solutions, including permission workarounds and memory checks suggested by other users, but none were successful.
After some troubleshooting, I found on the Nvidia website (https://www.nvidia.com/Download/Find.aspx?lang=en-us) that you can download the standard (non-DCH) driver. I tried the latest one (dated September 20, 2021), and it completely resolved the nvlddmkm issue. It has been 8 hours with no issues, and games are running well. However, the CPU fan still operates at higher RPMs, and the CPU temperature remains around 70-80°C. When I open Task Manager, CPU utilization drops below 20%, and the temperature falls to 40°C. Unfortunately, after 2-3 minutes, Task Manager crashes, and CPU utilization rises again. I am planning to reinstall Windows to see if that resolves the issue.
Based on my experience, it appears that the problem may be related to Nvidia's DCH drivers.
