Is it worth spending extra on 3600MHz CL16 RAM for Ryzen 5000?

Yes, it’s worth it — but don’t break the bank for a 5% gain. 3600MHz matches the Infinity Fabric 1:1, avoiding latency penalties from 3200MHz. If the price gap is within $20–30 of a 3200MHz CL16 kit, grab it; otherwise, put the money into a better GPU or SSD.
