Two identical 16GB kits on one mobo.

I have two 16 GB Trident Z cl14@3200 RGB kits (so 4 sticks in total 8GB each ) same partnumber same clocks voltages etc I just didnt buy a 32 GB kit of four sticks because I bought those two kits at different timepoints. 

 

 

I plan to install those kits on a TUF x570 board but I dont have it at hand... 

 

My guts and previous experience tells me that this should work without issue but nowadays you never know what silly restriction manufacturers add so that they can profit more...  I am concerned now if this will fail since I also installed a 2 stick 32GB trident Z kit on an other rig (taichi z370 ) and the thing would not boot unless I put a particular stick on first slot... (like it has 4 slots A B C D according to the manual in order to have dual channel with two sticks I need to install them on slot B and D but if I put stick 1 on B and stick 2 on D it wouldnt boot I had to put stick 2 on B and stick 1 on D lol  go figure..  ) 

 

So since I will have to wait for a week or so until the TUF board arrives and have time to spare reading forums and whatnot what's your opinion on this? will it work or should I buy new ram ?

Just try it. Most cases it will work but sometimes it just doesn't you don't know till you try.

Yeah should work just fine as long as you have the 4 physical slots, I have 2 seperate sets of 1x8gb in my pc that work just fine.

dual channel mode are working independently.

they should work in pairs, even though its not a matching kit, it should work.

I'm 99.99999% sure it will work.  I bought same brand, same speed, same timings, but different models from a ram manufacture 2 years apart...one "2 x 8gb" kit from 2017...one "2 x 8gb" kit from 2019...different model numbers and color/apperences...it worked flawlessly.  All clock at same speed with XMP turned on.

 

EDIT: My bad...I'm coming from an Intel setup.

Not necessarily, motherboard AIBs can't validate all memory configurations so they can't always guarantee ram compatibility

 

but given the memory performance improvements on X570 with new Ryzen, you can expect better compatibility these days.

I did this in the past on a bigger scale (4x 16 GB kits) x 2 for Threadripper 1st Gen. No matter what I did I could only ever get up to 96 GB. Only when we bit the bullet and bought 8x 16 GB did things go smoothly.
