Question Ram upgrade on old system

[lordpektroni]

Hello,

Currently, I have this motherboard (msi 990fxa-gd65 ) and i am thinking of upgrading the ram on it. I already have 2 x Crucial 4GB DDR3-1600MHz. I saw that my motherboard has 4 ram slots, so I was thinking of adding one more 8gb crucial ddr3 ram or 2 more 4gb identicals with the ones I already have. Is this possible? Thanks in advance

Possible - yes.
Will it work without any issues? Can't really tell. It might be ok or you may run into ram compatibility issues.
Mixing different ram kits together doesn't always work.

But it's the same ram dim basically

Ram modules are sold in kits for a reason. They get tested together before being sold in kits.
Modules from different kits are not tested together and are not guarantied to work together.
