Well, this is a tiny but important knowledge and I just noticed it today.
First of all, you need to know one thing: if DPC Latency is higher than 1000 μs, it will cause some strange phenomena such as sound lagging, and the video games have low performance.

Recently, I bought a Hynix CJR 16GB RAM to upgrade my old PC. It has two 8GB RAMs, which are also Hynix CJR. I plugged 16GB into A2 on the motherboard, 8GB into B1, and 8GB into B2, to build the 16GB + (8 GB + 8GB) dual channel.
The system can recognize the 32GB RAM, running at 3200 MHz, with timing 16-18-18-36, voltage 1.36V. I think it’s very lenient for Hynix CJR, even with three sticks of RAM. I can use 8G + 8G, with timing 16-19-19-36, voltage 1.36V, very perfectly, no problems.
But I met problems during these days. What strange problems I met so far:

The problem is caused by this:
If you have installed Steam on your D:\ driver, and you have the old Steam Library on your D:\ driver before, you will find Steam won’t let you add this old Library folder because Steam only allows one Library on the same driver. For D:\ driver, at present, it has been the default driver for Steam Library while you are installing the Steam main program. You can’t even change the default folder to another folder on the D:\ driver, it has been fixed by Steam.

Success is not final; failure is not fatal: It is the courage to continue that counts.

Recently, I noticed a strange bug: sometimes mouse wheel scrolling is not working on Linux. Some interfaces are even worse, they can’t scroll at all. But if scrolling slowly, it would work, just still tend to be stuck.
I tried many solutions, and finally, I decided to change the system-wide wheel scrolling speed. Unfortunately, most Linux desktop environment doesn’t have any settings to adjust the mouse wheel scrolling speed. So we need a tinny tool to solve the problem. That is imwheel.
*** This solution is tested fine on Debian 11. ***
