That's why nowadays I buy mostly from mdcomputers/vedant/primeabgb/theitdepot/onlyssd. You can OC 1600 too,it is just that X versions are supposed to have a much greater probability of reaching higher overclocks then normal versions of ryzen. AMD ryzen stock cooler are also good as they are made by coolermaster & as per many reviews reaching a 3.7-3.8Ghz with them is easy.
