I wouldn't trust in results from around the web. People say it's overclocking up to 4200+ but barely any result is actually stable for longer. A lot depends on the motherboard and BIOS. I'm not saying that because I can't set it so high (well, I can), I just see that all who are reading posts have high expectations and later are looking for issues in their hardware because they can't stabilize 4000+.
Samsung B is in a couple of revisions right now. Depends on the series, it can make ~3600 max or can pass ~5000 (these bad IC were mostly in ADATA kits as I remember). G.Skill is using better IC series in all 3000/3200 CL14, 3600 CL15/16/17 and everything 3733+. The same some other brands but at least from lower frequency kits, I would trust almost only Trident Z 3200 C14. However, new kits at more relaxed timings can be now Hynix or Micron. Both of them can make 3600 at CL18/19/20 and I guess this is in Ripjaws V 3600 CL19 kit linked in this thread. The same XMP can be found in Sniper X and competitive memory kits from new series.
Good luck with your new memory. It looks like a nice kit and should OC well
