Each memory cell corresponds to one bit and can assume either the status 1 (charged) or 0 (discharged). The advantage over retrieving data directly from the system memory, such as an HDD or SSD, is the significantly shorter access time and the higher transfer rate.Ī memory bar is made up of several memory chips, which in turn consist of millions of small capacitors and transistors. All data and commands that the CPU needs to run a program are stored temporarily in the RAM. RAM (Random Access Memory) is something like the short-term memory of your PC. (On AMD motherboards, instead of XMP for DDR4 modules, the name “D.O.C.P.” (Direct Over Clock Profile) is common.) This means that if you plan to use a PC 24/7, it is not recommended to activate such a profile. Even if the manufacturers carry out extensive tests for this, you do not receive an absolute guarantee regarding compatibility and stability. This is often accompanied by an increase in the supply voltage. The manufacturers of memory sticks and motherboards specify higher maximum RAM clock rates in these profiles. The easiest way to clock the RAM higher is to use the so-called “XMP” (Extreme Memory Profile) for Intel, or “EXPO” (Extended Profiles for Overclocking) for AMD. On many available motherboards, the maximum RAM clock listed is significantly higher than the above values. Ryzen Threadripper PRO 3000, Ryzen Threadripper PRO 5000 In the following table we have compiled for you the latest CPU generations from AMD and Intel, including the RAM clock rates specified by the manufacturers.Ĭore i3/i5/i7/i9-12000, Pentium Gold, Celeron, Core i3/i5-13000Ĭore i3/i5-10000, Pentium Gold, Celeron G To ensure maximum stability, CPU developers follow these guidelines. These concern, for example, the memory clock or the supply voltage. To ensure the long-term, stable use of a computer, there are specifications for RAM from JEDEC, an organization for the standardization of semiconductors. The stated values for the maximum RAM clock often differ greatly between processor providers and motherboard manufacturers. We have tested for you how much the clock rate and the latency of the RAM affect the gaming performance of your computer.įurther reading: What is DDR5? How is the maximum supported RAM clock determined? However, to get these clock rates, you have to adjust a setting in the BIOS (alternative: manual overclocking). Furthermore, higher clock frequencies are no longer unusual-in these cases, the use of a special profile allows the correct control of the RAM. Current CPUs from AMD and Intel now support RAM with quite fast clock rates: up to 3200MHz with DDR4 RAM and 5600MHz with DDR5.
