How to Enable XMP or EXPO (and Whether You Should)
Short answer: Restart and press F2 or Delete at the splash screen to enter the UEFI/BIOS. On the main EZ Mode screen, find the XMP or EXPO dropdown and set it to Enabled, or to Profile 1. Save and exit. Your memory then runs at its rated speed instead of the slower default, which typically improves average frame rates by 4 to 10% and does more for your 1% lows than for your headline FPS.
Most memory does not run at its advertised speed out of the box. The speed printed on the box is a profile stored on the modules, and until you switch it on your RAM runs at a conservative default. Turning it on takes about a minute.
What XMP and EXPO actually are
Intel XMP and AMD EXPO are the same idea from two vendors. Each is a set of pre-configured profiles stored on the memory modules themselves, containing a validated combination of voltage, timings and clock speed. Your motherboard reads that profile and applies it.
The practical benefit is that you get your memory's rated performance without manually overclocking anything. The manufacturer has already tested that combination and shipped it with the modules.
What you actually gain
In gaming terms, enabling XMP or EXPO tends to improve average frame rates by 4 to 10% depending on the title and your settings.
The more interesting part is where that gain comes from. The main improvement is to your minimum frame rates, which raises your 1% lows, a measure of the slowest 1% of frames in a session. That translates into a smoother experience with fewer noticeable stutters, which is often more valuable in practice than a higher average.
Outside gaming, it also helps program load times, and general performance in CPU-bound applications and anything that loads large amounts of data into memory.
The trade-offs, honestly
XMP and EXPO are still a form of overclocking. That has consequences worth knowing before you switch it on:
- The RAM and CPU run under greater stress, with increased power consumption.
- CPU temperatures can rise.
- There is potential for occasional system instability, meaning crashes.
Some people deliberately leave it off in favour of maximum stability, and that is a legitimate choice rather than a wrong one. If your PC is doing work where an occasional crash is genuinely costly, leaving it disabled is reasonable.
Does it affect your warranty?
Enabling these features does not affect your NZXT system warranty. What we cannot do is guarantee stability while they are active, since you are running the hardware beyond its base specification.
Mixing memory kits
These profiles are designed for a single kit, meaning two matched modules. Mixing modules from different kits, or running more modules than a single kit contains, can cause greater instability and is not guaranteed to be supported.
If you are planning to add memory to an existing system, check your motherboard's Qualified Vendor List (QVL) for validated configurations before you buy.
How to enable it
The exact layout varies by motherboard manufacturer, but the flow is the same everywhere.
- Restart the PC and press F2 or Delete at the startup splash screen to enter the UEFI/BIOS.
- Most gaming systems load into an EZ Mode screen, which shows the XMP or EXPO control directly on the main page. On Asus boards it sits on the left side of the screen.
- Open the dropdown and choose Enabled, or a numbered profile such as Profile 1.
- Check the memory specifications that appear alongside the dropdown to confirm the profile applied.
- Choose Save & Exit and let the system restart.
The system may restart more than once while it applies the new memory settings. That is normal.
Which profile should you pick?
Some memory kits offer several profiles.
- If your kit supports both AMD EXPO and Intel XMP, choose the one matching your platform.
- If you see multiple numbered profiles, Profile 1 is the recommendation for best stability.
Vendor-specific walkthroughs
Screens differ between motherboard manufacturers. NZXT support has step-by-step guides with screenshots for the boards used in our prebuilt systems:
You can confirm which motherboard you have in the UEFI/BIOS itself, in the Windows System Information app, or under System Specs in NZXT CAM.
If the system becomes unstable
If you get crashes after enabling a profile, work down this list:
- Switch to Profile 1 if you selected a higher-numbered profile.
- Confirm you are running a single matched kit rather than mixed modules.
- Check your motherboard's QVL for your specific memory configuration.
- Disable the profile entirely and confirm stability returns, which tells you the memory settings are the cause.
If the system will not POST at all after enabling a profile, most boards recover by themselves after a few failed attempts. If yours does not, clearing the CMOS resets memory settings back to defaults. Our guide to clearing CMOS covers three ways to do it.
Frequently asked questions
Is XMP safe?
It uses a profile the memory manufacturer has validated, so it is far safer than manual overclocking. It is still overclocking, so it carries a small risk of instability and it raises power draw and temperatures. It does not affect your NZXT system warranty.
Why is XMP not enabled by default?
Because it is a form of overclocking, we historically left the choice to the owner. Newer prebuilt gaming PCs may ship with XMP or EXPO already enabled.
What is the difference between XMP and EXPO?
XMP is Intel's standard and EXPO is AMD's. They do the same job. Many memory kits carry profiles for both, in which case you pick the one matching your platform.
Will XMP increase my FPS?
Typically by 4 to 10% on average, depending on the game and settings. The bigger practical benefit is to 1% lows, which is what makes gameplay feel smooth rather than stuttery.
Can I enable XMP with four sticks of RAM?
You can try, but these profiles are validated for a single two-module kit. Running four modules, particularly from different kits, increases instability and is not guaranteed to work. Check the QVL for your board.
My PC will not boot after enabling XMP. What now?
Most motherboards revert to safe memory settings automatically after a few failed boot attempts. If yours does not, clear the CMOS to reset the memory configuration.
