AEMP II for Ultimate DDR5 Performance


ASUS Enhanced Memory Profile II (AEMP II) is an exclusive firmware feature for PMIC-restricted memory modules. AEMP II is based on a CPU and memory module’s ability to train the memory chips on your kit, and it presents an optimized clock speed that can effortlessly unleash performance.


Built through a flexible training method, AEMP II makes it easy to not only tune the memory above baseline settings but also maintain the stability of system operation, whether getting the most out of an entry-level module or priming a high-speed kit for ultimate performance.


*Results may vary according to the capabilities of your CPU and memory modules.
**The comparison chart is based on a test with an Intel® i9-13900K processor and 2x16 GB SK Hynix DDR5-4800 non-ECC UDIMMs, model HMCG78MEBUA081N.
***Please ensure all memory modules are from a single validated kit. Do not combine DIMMs from multiple kits—even if they are the same make and model. Mixing and matching DIMMs can result in failure to boot, and compatibility cannot be guaranteed.
****Always install DIMMs with the same CAS latency. For optimal compatibility, we recommend that you install memory modules of the same version or date code (D/C) from the same vendor. Check with your retailer to get the correct memory modules.
