OC memory limited ? not for Asus:
Once again, if you haven’t already done so, have a look at our article on Alder Lake. And more particularly the section about the new DDR5. One of the major changes is the addition of a PMIC(Power Manager Integrated Circuit) module. Its role is to regulate the power supply of the memory stick. So there is one for each memory stick. Previously, it was the motherboard that was in charge of managing the power supply. In reality, this has both an advantage and a disadvantage. The positive point is that manufacturers no longer have to provide this control on the motherboard PCB. But unfortunately, PMIC reduces quite drastically the potential for the motherboard to control the stick, such as a voltage lock(secure mode). Basically, there are two types of PMIC: one that accepts overclocking and one that is blocked. It is impossible to modify the voltage and therefore, the potential for overclocking is very limited!
A solution ” made by Asus “:
Asus could not do without looking for a solution. So the engineers worked to get around this limitation. And it is solved! Within the BIOS, you will find profiles according to the memory chips that equip your memory kit. We are working on our Discord in order to offer you a summary of the available kits.
They can be used by novices who do not want to risk getting into memory overclocking but also for experienced users for whom it will be a starting point. The profiles are present because DDR5 would benefit from an excellent overclocking potential. The profiles are optimized to offer high frequencies and tight timings. The voltage can be manually adjusted up to 1.435 volts. However, it seems that a very slight increase already brings a very interesting gain. We will judge this during our tests. In the case of a PMIC that is not blocked, the voltage could reach 2 volts. In the “memory overclocking ” section, we have used these profiles.
