What are XMP and EXPO, and how to get your RAM to its rated speed
Fast RAM usually starts at a basic speed when you first put it in. Turn on XMP (Intel) or EXPO (AMD) in the BIOS and it runs at the speed on the box.
Check the speed it runs at
The Home page of Savenz Optimizer warns when XMP / EXPO is off and shows the MT/s your RAM runs at. Export PC Specs lists every stick: the MT/s it really runs at next to what it supports, the brand and the model.
If the running speed is lower than the supported one, the profile is off.
How to turn it on
- Restart and press the BIOS key while the PC starts, usually Del or F2.
- Find XMP or EXPO. Some motherboards call it DOCP.
- Pick Profile 1.
- Press Save and Exit (usually F10) and let the PC start.
- Open Savenz Optimizer and check that the RAM runs at its rated speed now.
The first start after turning on XMP / EXPO can take longer than usual while the motherboard tests the RAM.
Crashes or blue screens after turning it on
Some RAM kits or motherboards are not stable at that profile. If you get a MEMORY_MANAGEMENT blue screen or more game crashes after turning it on, turn it off again first.
Unstable RAM can damage files FiveM downloads from servers. If FiveM crashes on many servers even after clearing the cache, try it with XMP / EXPO off.
Fill both RAM channels
XMP helps the speed, but one stick, or two sticks of different sizes, runs in single channel. CPU heavy games like FiveM lose a lot of FPS. Use two sticks of the same size in the slots your motherboard manual names.
Want more than XMP?
XMP / EXPO is the factory profile. For tuned sub timings and a better 1% low, there is an OC RAM service in the Savenz Discord.
