i have 2 ADATA XPG GAMMIX D30 8GB DDR4 3200MHZ RAM sticks in my computer (Ryzen 5 3400G, ASRock B450 Pro 4). facing occassional BSOD issues for the last month. today i checked the memory with windows memory diagnostics.
as soon as it started, it showed "Memory problems can cause your computer to lose information or stop working. To identify and repair the problem, contact the computer manufacturer."
it appears either of them has developed some fault. soon i will check it with memtest86 and hope to identify which one has the issue. if it has some issue, then it needs to be replaced.
i am thinking of adding a single 32gb module in it along with the good 8GB one. will there be an issue even when both of them are 3200mhz? any specific brand to go for?
i am asking this because i was looking at crucial ram on their website but their compatibility test says their 32gb CT32G4SFD832A is not compatible with this motherboard and suggests only 16 X 2 sticks.
thanks.

CT32G4SFD832A is an SO-DIMM (Small form factor memory modules for Laptops and Mini-PCs). Of course, it won't be compatible with a standard motherboard.
Try CT32G4DFD832A instead.
As for mixing one 32GB DIMM and one 8GB DIMM, it will likely work, but is not something anyone would recommend. It's best to have symmetric DIMM setup on the two memory channels for maximum performance and reliability.
I would never even mix two DIMMs I bought at different times. If the bad DIMM is still under warranty, maybe you can try to get it replaced. I thought most reputable brand DIMMs have "lifetime" warranty. Otherwise, I'd stick to replacing both with a pair of matched DIMMs.
