1.  The system has no adjustment or capacity for reading XMP on the memory modules nor any manual adjustment in UEFI setup.  There is no advantage to high performance RAM (Vengeance, HyperX, etc.). 2.  The CPU you have won't run RAM any faster than 2666 MHz.  If you install faster RAM, it'll simply downclock.  
Hi, it has been almost 2 years since i bought my Dell G5 5587 laptop with i5-8300h cpu and 8gb (2x4gb) of 2666MHz ddr4 RAM, and i believe it is finally time for me to upgrade to 16gb. Unfortunately there are so many upgrades on the market that it is hard to make a choice, and it got even worse when i came upon an old post that mentioned compatibility problems between my laptop and ram sticks that support xmp. From there i decided to see what ram sticks would work for me according to crucial compatibility tool [URL] Well, lets just say that after searching on that website i got confused even more as it showed compatible ram with 3200MHz that i'm pretty sure would not work on my laptop that supports only up to 2666MHz ( correct me here if i'm wrong ? ). Or maybe it does work but runs at lower speed and is basically useless for me to buy ? So the reason im writing this is, i would really appreciate if someone would answer these simple questions for me: 1. Does Dell g5 5587 really cannot run ANY sticks that support xmp ? If so how do i tell which ones are without xmp, most websites doesnt mention that. My first choice that i wanted to buy were Corsair Vengeance 2666MHz DDR4 2x8gb but i believe they do have xmp built in. I also considered HyperX Impact 2666MHz DDR4 2x8gb. ( links to both below, sorry for non-english website but the spec is visible ) [URL] [URL] 2. Is my laptop actually able to run 3200MHz ram like the crucial website says ? I've seen many posts saying that all the RAM sticks from there would definately be compatible with my desktop.    If that makes any difference i'm running the latest 1.13 bios version.
