XMP or Extreme Memory Profiles, is an Intel era that allows you to change assorted memory settings by simply selecting a unique profile, taking knowledge of upper than simple memory speeds. How it worksRead more: Intel Core i7 9700K reviewWhen you power on your computer, it conducts a power on self test. Part of this system includes instantly configuring installed hardware, adding your memory. Your computing device needs to know the model of your RAM in addition to which timings and frequency to set. Your BIOS will use a small chip on your RAM modules called an SPD serial presence detect chip to set memory timing and frequencies correctly.
XMP is an extension of SPD which provides higher frequencies and tighter timings on your memory to run at. It also corrects for the additional voltage required which adds a stable overclock with the click of a button. XMP profiles pretty much allow high performance RAM, which run above market DDR specifications, to be appropriately set on your system. Which button to click and whereXMP profiles can be accessed from within the BIOS on supported motherboards. Supported memory modules comprise two various XPM profiles which provide various levels of overclocking.
Simply select one of the two profiles, save your settings and reboot. You can ascertain your new overclock using a software corresponding to CPU Z. What if I don’t switch on XMP?All high functionality RAM uses XMP profiles, as a result of all of them run above fundamental DDR industry specs. If you don’t enable XMP, they will run at your system’s fundamental specifications which are dependent on the CPU you have. That is to say, you will not take expertise of the higher clock speeds that your RAM could have.
In most cases, this can be fine. Your system will simply run to spec, and you’ll rest easy understanding every thing is nice and stable. However, XMP allows your system to set motherboard and CPU parameters accurately, to permit higher frequency RAM modules, that are designed to run beyond usual specifications. Why are there two profiles?XMP supported modules comprise two memory profiles labeled “Profile 1” and “Profile 2”. The first profile consists of fanatic settings; these allow your memory to run at the rated speed marketed on the box.
These settings enable only a modest overclock and are also the most stable. The second profile consists of more extreme settings that supply a much higher level of performance. Having two profiles allows you to quickly change performance levels for benchmarking or aid heavy tasks. Is XMP stable?Any time overclocking is involved, there is a risk of instability. With XMP the configurations included are totally tested for the real memory you are using.
The timings, voltage and frequency are set to compliment one another and mitigate much of the instability that can creep up with a manual overclock. No automatic configuration can account for outside factors such a CPU overclock. This is something to keep in mind if you adventure any instability.
