I have 
Acer Nitro AN515-57-74P3 (NH.QDGSG.003) which comes with a 8GB RAM 3200MHz 1Rx16 module that has CL22 (CAS Latency 22). To be exact, it is 
Kingston ACR32D4S2S1ME-8 product.
Can I remove it entirely and replace with a pair of 8GB RAM 3200MHz 
1Rx8 CL20 modules instead, please?
So it would then be like:
- 1x 8GB RAM 3200MHz 1Rx16 CL22
 - 2x 8GB RAM 3200MHz 1Rx8 CL20
 
Basically I don't like 
CL22 as well as 
1Rx16 modules.
My questions are:
- Does my system (motherboard) support those new pair of RAM (CL20 / 1Rx8) modules?
 - Will those new pair of RAMs be supported so that the "duel channeling" mode should also kick-in as well?
 
Please help me confirm it.
Would prefer and appreciate the advise from Acer technicians.
Thank you all
