Overclocking the same RAM model?

[Duplo]

I want to upgrade from 16 to 32GB using my two free RAM slots.

My memory is a Crucial 3200Mhz CL16 (2x8GB).

I am using my motherboard's "Memory Try It" feature, basically I just selected 3600Mhz CL16 from drop down menu and it overclocked to it (anything better will fail).

If I buy another exact same RAM set (same model number, etc.) to go to 32, what's the likelyhood all 4 RAM will run at my existing overclocked speed? Would hate to have to bother returning the RAM.

You probably need to share a little more info on the system to see if it is worth chasing higher memory clocks/tight timings: This will depend on the memory controller in your CPU (the later Ryzen 3000 and most Ryzen 5000s have better track records with handling more memory channels)... it will depend a lot if you can get EXACTLY the same memory chips. Given you've got Crucial, I assume it'll all be the same higher-binned (better) Micron chips, so you'll be in a far better position than I was with the same dilemma on my Corsair memory (see grumble here) - where they changed from providing very high spec Samsung memory modules to Hynix.

All that said, the general rule is that even with PERFECTLY matched memory, the most you will be likely to achieve will be the XMP/DOCP quoted speeds and currently you're getting a fairly significant step above those - there's a reason why most of the really high end overclocking board only have two memory slots

Make you choice: if you still want 3600Mhz, then sell your current memory on and buy two new sticks with the size and speed you want - it's highly unlikely you'll achieve the same overclock with 4 sticks. If you think you'll be happy with 3200Mhz C16, then you should be fine, provided you can find exactly the same model.... or settle for slightly looser timings if you can't.
