As attached in pic shown,I have 32 gb ram but it is shown about 16gb usuable, and says its cached what does this mean, can I make all 32gb usuable. Strangly   I have another pc with same motherboard with 1700 ryzen and 4 times 8gb ddr 4 ram[windows 10]. Which shows all 32gb usable.

Ryzen 5 1600[processor]

ASUS PRIME B350-PLUS[motherboard]

That is normal for Windows. It takes memory that is not being used and creates a disk cache with it. If memory is required by an application the cache will release memory to it. You will see that number change based on what programs you are running.

I do not agree, this is not normal. His screen shows 13 GB cache and 2.8 GB in use. This means, the system is really limited to about 16 GB. You can also see on the left size, that it only sees 15.9 GB as usable. On my system those numbers sum up correctly to 32 GB and it also shows 32 GB on the left side. You could set such a limit with msconfig (Boot -> Advanced Options...), maybe some 'optimization' tool did so.

His Cache system is working perfectly fine, the issue is his system is reserving 16gb of memory for hardware. I suspect he is using a ram drive or some other application that is reserving memory at a hardware level. Perhaps Windows has and issue with malware. Are your sticks in the right slots? The manual is your friend.

He may be able to go into disk management and find a 16gb ram drive that is not formatted.

gigabytes is likely correct, the most likely things that are happening is (since it shows 32gb just it has 16gb as usable)

• If all the ASUS software was installed, there's likely a RAMdisk (my MSI board took 4gb of my 16, so 16 of 32 is possible). check start menu for RAMdisk software, if so, remove from settings.
