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:
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.
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. ***
Make sure you allocate enough CPU and RAM. If you’re running Desktop Environment, you should allocate at least 2G RAM. 4G RAM recommended.
If you meet any graphic problems, turn off 3D Acceleration. It will solve most graphic problems.
If you find disk I/O is very slow, go to Storage setting page, click “Controller: SATA”, then check “Use Host I/O Cache”. You will find your Virtual Machine run fast beyond your imagination, even thought the disk is on HDD, not SSD. So you should enable this before installing Operating System, it will speed up your installation. (VirtualBox disable this by default)
Set sound hardware as AC 97, not Intel HD, to get best compatibility. Otherwise, you will meet some strange problems while playing sound, especially laggy or stuck.
Try to turn off 3D Acceleration in VirtualBox or VMware.
When you turn off 3D Acceleration, CPU will load much heavier instead of GPU so that you should increase your CPU power (increase your Virtual Machine CPU number, or upgrade your physical machine CPU). Though CPU will load heavier than before, that’s worthy because it only takes heavy load while running Pygame. While using other applications, CPU behaves as usual.
The system will pop this warning notification, just ignore it.
For VirtualBox users, maybe you find after switching VMSVGA to VBoxVGA or VBoxSVGA, it works more normally. That is because VBoxVGA and VBoxSVGA won’t enable 3D Acceleration. I recommend using VMSVGA by default.
So when you face the graphic problem, don’t waste your time like me, just turn off 3D Acceleration.
