For example, a motherboard and CPU that can support up to 2133 MHz memory can use 2400 MHz RAM but only run it up to 2133 Mhz. If your present computer has a 2133 MHz module installed in it and you install one rated at 2400 MHz, the system has to run the memory at the speed represented by the slower of the two.
XMP is safe to use.The memories are made from factory to run at 3200 mhz,they were designed for this.Enabling XMP doesnt affect your pc in a bad way. An XMP preset is an overclock setting for your memory. Anything more than 2133 for DDR4 is an overclock. It carries the same risks as overclocking any other component.
Overclocking can cause damage to your CPU/GPU: FALSE
Overclocking in and of itself cannot damage a C/GPU. If a video card or CPU is set to run at a speed it can't run it, it will reset (CPU) or crash (GPU). This causes no damage to the component.Memory tweaking tips
Most DDR3 RAM runs at 1,333MHz, but overclocking RAM such as G. Skill's RipJawsX will happily run at 2,133MHz. Ramp it up incrementally, though. If your PC boots, restart it and increase the frequency some more.Your RAM's speed does not alter how fast your CPU goes, even when overclocked or hyper-threaded, but it can slow the CPU down depending on if your RAM is full or not. RAM speed comes down to how much data is transferred at a given time, and much of that can be determined by the number of your RAM module.
You can check how much RAM you have in a variety of quick ways. On Windows 10, use the Task Manager. Right-click your taskbar and select “Task Manager” or press Ctrl+Shift+Esc to open it. Click the “Performance” tab and select “Memory” in the left pane.
Start off by lowering the first (tCL) and third (tRP) timing by 1. If this passes one round of Memtest86+, try lowering the second timing (tRCD) by 1 and running the test again. Note: If you haven't reached your maximum RAM voltage, increasing it will usually allow you to tighten your timings even further.
Manual Overclocking
- Follow the XMP step above first and then stress test it. This will give you an idea what speeds, frequency and timings you can have with your RAM. (
- Go back into your BIOS and navigate to the Ai Tweaker only this time you want to select 'manual'.
- Now onto the timings.
- Test for stability and repeat.
RAM doesn't really perform too much better at cooler temperatures, but serious overclocking still heats up the memory chips. If you are already using a CPU liquid-cooled loop, putting in a water block for the RAM is relatively easy if that's the route you want to go.
Memory timings or RAM timings describe the performance of synchronous dynamic random-access memory (SDRAM) using four parameters: CL, TRCD, TRP, and TRAS in units of clock cycles; they are commonly written as four numbers separated with dashes, e.g. 7-8-8-24. Lower numbers usually imply faster performance.
The next thing to do (if your CPU overclock is stable), is to set XMP (Extreme Memory Profile) to clock your RAM at a certified profile (usually the advertised specs). For example, my RAM is rated at DDR4-3600 with timings of 15-15-15-35 using 1.35v. Set the Ai Overclock Tuner to XMP.
Extreme Memory Profile (XMP) is a specification serving as an extension to the standard JEDEC SPD specifications developed by Intel. XMP is intended to make overclocking easier and more accessible to new users through profiles and predefined overclocking configurations that are known to be stable.
