It is not recommended, but it can be done.

 

However, your RAM performance will be limited to the performance of the weakest RAM Stick, eg. the higher performing RAM sticks downlock themselves to match the slower RAM stick.

Whats the worst thing that could happen? Maybe frying some memorychips?

No. Instability could happen, but doesn’t have too.

It won't hurt anything to try, but you might not get all the performance the memory is theoretically capable of.

 

Worst case, your PC will be unstable. If that happens, pop the low capacity DIMMs out.

I currently use a system with mixed RAM (different manufacturer and different speeds).

Everything works fine most of the time, but what can happen is that some applications may crash (as when you run out of memory) and you may get the occasional MEMORY_MANAGEMENT BSOD.

However, this is very rare.

That means your system is unstable.

The system won't get through POST
