I currently have two 8GB DDR4 3600 RAM sticks in my PC, and I just upgraded to two 16GB DDR4 3200 sticks. However, when I try to boot up with all four installed, my PC only recognizes the 24GB from the first two sticks. I can use the two sets of RAM individually without issues, but when I combine all four, it doesn't work. Any advice on how to resolve this?

Your motherboard's memory controller might struggle with all four sticks, particularly if their specs differ. Sometimes, it just doesn't play nice. If you have the option, try using just the two faster sticks to keep things stable and save yourself some hassle with performance tuning.
Mixing RAM sticks can be tricky, especially when they have different speeds. Since you’ve got some at 3600 MHz and others at 3200 MHz, that can cause issues. It could help if you lower all four sticks to 3200 MHz. Just make sure their timings and voltage closely match the slower sticks—this might improve compatibility.
If you want to run all four sticks, you might want to clear your CMOS after installing them. This can help reset settings and allow for better memory training. Also, avoid overclocking any RAM when testing; sticking to your motherboard's default speeds might lead to more stability.
Definitely! Running at standard speeds is usually more stable, and if you're encountering issues because of speed mismatches, that's a wise move.
Keep in mind that mixing RAM can lead to instability. It might be better to stick to one high-capacity dual-channel kit instead of mixing brands and capacities—this will likely save you any future headaches with compatibility.
That's a good point! If the two sets of RAM aren't entirely compatible, going with the faster kit alone could save you from a lot of headaches.
