How to know if ram is working fine

My laptop had 8GB of ram but recently i upgraded as there were too many issues happening… i added 16Gb of Ram so right now total is 24GB.

The laptop seems to function normally but how can i be sure that the ram i added will not create some issues… and its working properly

Computer components are very social. They in most cases are respecting the speed/technology of an older device.

In your case this would mean, if the older Ram you had, is a slower ram than the 16GB you bought, it will perform on specifications as your older ram.

If you do a performance test with the 24GB and tests with the 16GB, the 24GB should be faster/better. If not the older Ram is probably slow down your system.

In this case it would make sense to sell your 8GB on the second hand market and organize you a exact same as you bought. This not just increases your amount of Memory it also guaranties that you have same memory units who work perfect together.

Of course, before you do so, you have to check if your hardware supports two 16GB units.

If you already had issues you might let the 8GB extra out of your system, to see if the issues are gone.

Well both are rated for same speed @3200mhz so i dont think it will run slower, its just that one is 8GB and another is 16GB… so i was thinking if there is way to test for system stability…

Ok i saw that just the brand is different. What kind of issues did you relate to the memory?

To tell you the truth i dont know…

For non-UEFI system you can use memtest86+ from the fedora repository, and it can extensively test the ram memory.

For UEFI systems you may take a look at

There is also a memtester package in the Fedora repository.

I have only ever used the memtest86+ utility, so I can’t comment on the others.


The system seems mostly happy with that arrangement, though it may not be able to run in dual channel mode with mismatched memory DIMMs like that.

As already mentioned, I would suggest that either you buy an additional 16 GB DIMM matching the new one you just installed and remove the 8GB one, or just remove the 8GB one and run with 16GB memory. This avoids potential conflicts and using 2 matched DIMMs would enable dual channel RAM if the mobo supports that. Dual channel RAM would beat single channel RAM hands down.

The inxi output shows the system supports a maximum of 32 GB (in 2 16 GB modules)

I dont have money to buy another 16GB kit and i heared that AMD has something called flex mode where it will run in dual channel for the size of lowest ram module, means in 16GB the 8GB of the space will run in dual channel and other half of will run single channel…

what is your thought on flex mode?

Overall experience from before is really great btw… things are running extra smooth without hang of any kind…

Good for you. I do experience this since 2013 with my 16GB (only). It really depends what you try to run and for what you will use your system. So, i guess everything is fine then. The tools available you got an answer already.

No experience with it. Sounds good though.
