XMP: Intel Extreme Memory Profile
EXPO:AMD EXtended Profiles for Overclocking
DOCP: Direct Over Clock Profile
Load the preset overclock file and DRAM timing from memory SPD chip to quickly overclock to a stable frequency
*For DRAM compatibility, please use DRAMs that in our QVL list

Q6: DRAM max frequency is related to which device ?
Intel platform Motherboard enabled XMP or DOCP in BIOS
(Below is for example, the BIOS settings and options may differ slightly on different Motherboard and BIOS version)
1. Power on the system and press <delete> key to enter BIOS [EZ Mode]
2. Press <F7> key and go to [Advance Mode]
(If enter BIOS [Advanced Mode)] directly , and then no need to press <F7> key again)
3. Click [Ai Tweaker] page as below
4. Click [Ai OverClock Tuner] item
If DRAM support XMP ,then set to [XMP I]
If DRAM support EXPO ,then set to DOCP
5. Press <F10> key and click <OK> , the system will auto reboot
AMD platform Motherboard enabled EXPO or DOCP in BIOS
(Below is for example, the BIOS settings and options may differ slightly on different Motherboard and BIOS version)
1. Power on the system and press <delete> key to enter BIOS [EZ Mode]
2. Press <F7> key and go to [Advance Mode]
(If enter the [EZ mode] first ,please press <F7> key to enter [Advanced Mode])
3. Click [Ai Tweaker] page as below
4. Click [Ai Overclock Tuner] item
If DRAM support EXPO ,then set to [EXPO I]
If DRAM support XMP ,then set to [DOCP]
5. Press <F10> key and click <OK> ,the system will auto reboot
Q&A:
Q1: How to troubleshoot if XMP or EXPO or DOCP fail ?
A1:It is recommended to use the DRAMs in QVL, and for 2 or 4 pieces, please use the suit, do not mix and use
* Please replace the higher specification CPU to verify if you have one
| Number of DRAM | item 1 | item 2 | item 3 | item 4 |
| one | Install as recommend | install in other slot | ||
| two | Install as recommend | exchange each slot | install single DRAM in recommend slot | install in other slot |
| four | Install as recommend | exchange each slot | install single DRAM in recommend slot | install in other slot |
Q2: How to check DRAM frequency after enable XMP or EXPO or DOCP ?
A2:BIOS EZ Mode Memory information show DRAM frequency
Windows 10 or Windows 11 OS[Task Manager]-[Performance]-[Memory]
a. Open [Taskbar setting ] and click [Task Manager]as below
b. Click [Performance] on [Task Manager] page
c. Click [Memory] on [Performance] page and show memory speed
Q3: How to reset BIOS to default setting if XMP or EXPO or DOCP fail ?
A3: Please CLRTC to recover BIOS setting，check FAQ: How to Clear CMOS
Q4: How to check DRAM support XMP or EXPO ?
A4: Please refer to BIOS setup Tool\ASUS SPD Information as below picture
If DRAM show XMP ,it means that the DRAM support XMP
If DRAM show EXPO ,it means that the DRAM support EXPO
Q5: How different DRAM type show in different platform ?
A5: Please refer as below table
Platform | DRAM Type | |
DRAM support XMP | DRAM support EXPO | |
Option show in BIOS setup | ||
Intel（600 series and after | XMP | DOCP |
AMD（AM5 series and after） | DOCP | EXPO |
Intel（Before 600 series） | XMP | N/A |
AMD（Before AM5 series） | DOCP | N/A |
Q6: DRAM max frequency is related to which device ?
A6: The max frequency of DRAM is related to DRAM，Motherboard and CPU SPEC
