Crucial's guaranteed to work memory is CAS 22. [URL]  
Anybody knows if the G3 3590 has a specific CAS Latency for ram? My model is with the 1660ti max q and i5-9300h. I recently bought the 2x8gb 2666 gskill ram from newegg, and after installing it, it worked for about a week until it started to crash and freezes. Old ram works fine. I saw on their review page that the problem is probably due to the laptop doesn't support this CAS Latency. The one I bought has a 18 CAS Latency.
