Heatsinks and CPU cooler clearance: Every kit that I recommend in this guide feature either no heatsinks or small heatsinks that don’t raise too much above the RAM sticks. Why?
• Because RAM heatsinks barely make any difference when it comes to RAM temperatures. Besides, even if you overclock it/raise the voltage (at your own risk), RAM temperatures aren’t a problem as long as you have decent airflow in your case. • Tall RAM heatsinks can get in the way of larger aftermarket CPU Coolers, preventing you from installing your aftermarket CPU Cooler! Important: RAM can require manual configuration within the BIOS to reach its full potential or function properly! By default, some RAM kits will boot at lower frequencies than they are rated for. This is perfectly normal, it does not mean that your RAM is defective. You simply have to go within the BIOS (The first thing that you see when your PC starts) and enable XMP, for your RAM to function at its rated speed. If XMP is not available or doesn’t work for some reason, you can adjust the RAM settings manually, such as frequency (In MHz, usually linked to the CPU, look for a CPU:RAM ratio), voltage (e.g. 1.65v) and ti
