Manually overclocking RAM can be dicey if you don't know what you're doing and can lead to instability.<\/p>\n<p>XMP can be thought of as manufacturer verified, safe overclocks on your RAM that you can simply turn on if you want without needing to bother with the tedium of manual overclocking.<\/p>\n<p>However, if your system doesn't support the overclocks that the XMP profile of your RAM has, your system might crash and bootloop (restarting over and over again).<\/p>\n<p>You will have to go to your BIOS and reset your XMP profile to the default one to get your system stable again.<\/p>\n<p><a href=\"https:\/\/g100.us\/xmp-memory-profile-guide\/\">Take a look at our guide about XMP profiles to learn more<\/a>.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"How_Do_You_Enable_XMP\"><\/span>How Do You Enable XMP?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Different motherboards have different UIs and procedures needed to turn on XMP, so sadly there's no universal &#8220;do this and it'll work&#8221; method to turn on XMP for your RAM.<\/p>\n<p><a href=\"https:\/\/g100.us\/xmp-memory-profile-guide\/\">However, we have a very in-depth article about XMP profiles that'll help you figure out what you need to do for the most popular motherboards<\/a>.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Are_Heatsinks_Necessary_for_RAM_Sticks\"><\/span>Are Heatsinks Necessary for RAM Sticks?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Not necessarily. I would say that a majority of RAM used for simple tasks such as gaming, browsing, media consumption, etc., don't <em>need<\/em> heatsinks. RAM just doesn't get that hot.<\/p>\n<p>If you're running extremely high-speed RAM with applications that tap into that RAM constantly, then you'll most likely benefit from a heatsink.<\/p>\n<p>Also, they're just plain cool to look at.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Is_Running_RAM_at_Full_Speed_Bad\"><\/span>Is Running RAM at Full Speed Bad?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Unless you're concerned about power draw (practically nothing compared to the rest of your PC) or stability (you should be fine if you're running an XMP profile), then no, there's nothing bad about running RAM at full speeds.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Over_to_You\"><\/span>Over to You<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Hopefully, that explained to you some of the things that might be hampering the performance of your memory.<\/p>\n<p>If you have your XMP profile turned on and you're not getting the speeds you were advertised to, 90% of the time it's because of compatibility issues with your CPU or motherboard.<\/p>\n<p>Sadly there's not much you can do about that other than replacing them, but the knowledge will help you be more informed for any future purchases.<\/p>\n<p><strong><em>Have any other questions about PC components?
