Overclocking, the eternal topic of DIYer. Although the miracle of Celeron 300A cannot be repeated, and there are many restrictions on overclocking today, there are still many players who are happy to do so, and manufacturers are willing to provide a platform that is as open as possible. Intel’s latest Alder Lake 12th-generation Core processor, the first six K/KF series models, and the Z690 motherboard, all unlock overclocking skills and add a lot of new gameplay, especially the first DDR5 memory, which is worthy of deepening. Dig.

The 12th-generation Core adopts a hybrid architecture design. This time not only the high-performance P core can be overclocked, but the energy-efficient E core also supports it, and it can also control the internal BCLK reference external frequency.
At the same time, DDR5 overclocking is more abundant, not only supporting XMP 3.0 one-key overclocking, but alsoDynamic Memory BoostWait for new skills.
In terms of software, Intel XTU overclocking software has also been upgraded to version 7.5. Of course, you can also dig deeper in the motherboard BIOS.
Overclocking architecture diagram of the 12th generation Core platform,P core frequency multiplier (xP), E core frequency multiplier (xE), ring bus and cache frequency (xR), core display frequency (xG), memory frequency (xM), reference clock frequency / external frequency (BCLK), All can be adjusted.
Of course, the adjustable space of the “FSB” has always been very small, so basically there is no need to consider it, unless it is an impact limit record.
More specifically, in terms of overclocking options, there are traditional AVX offset/off, per-core hyperthreading switch, per-core multiplier, real-time memory frequency, voltage control and other options, as well as supportPLL control, FSB adaptive voltage, PEG/DMI bus overclocking, TjMax temperature threshold offset, switch per coreWait for the new gameplay, Intel has opened up more than 20 settings in total.
The function of Intel XTU 7.5 software has become more and more powerful, most of the time you don’t need to go to the BIOS to modify it.This time for the 12th generation Core Duo, the E core and DDR5 overclocking control have been specially added., It also integrates XTU Benchmark 2.0, which is convenient for checking the stability of overclocking.
If you don’t like complicated overclocking, or don’t understand, Intel also providesOne-click overclocking based on ISO technology, it will automatically detect the frequency, voltage and other parameters of the P core and E core, and set the most suitable overclocking frequency, Of course, the range will be conservative.
Next, talk about XMP.
This is the recommended overclocking method for memory developed by Intel. It was born in 2007 and originally served DDR3. Currently, the most widely used version of XMP 2.0 corresponds to DDR4. Now it is upgraded to XMP 3.0 to support DDR5.
XMP 1.x/2.0 only supports two sets of profiles, XMP 3.0 has increased to five sets, three of which are factory presets that cannot be changed, and the other two allow players to read, write and modify. In order to prevent random changes, it also supports CRC. Error checking.
At the same time, the file name of the configuration file is also open toUp to 16 characters, The storage space has been expanded from 102 bytes to384 bytes。
What’s more worth mentioning is that DDR5 memory integrates PMIC power management circuit, soThe voltage can be adjusted independently more openly, mainly VDD, VDDQ, VPP, And they are all standardized by JEDEC and Intel, and they are consistent on different motherboards.
Currently,Corsair, Zhiqi, Micron Inrad, Kingston Fury, Pride, Team Group TForceSix other memory manufacturers have fully supported XMP 3.0, and Corsair also provides specialized software IQsoftware, which is more convenient to use.
Finally, talk about dynamic memory frequency adjustment, a smarter way of memory overclocking, a bit similar to turbo frequency.
It is limited to the 12th generation Core, but supports DDR4 and DDR5 at the same time, The only requirement is that XMP is officially certified by Intel.
After enabling this function in the BIOS, if the system load is high, it will automatically switch to the XMP high frequency configuration, and when the load is light, it will return to the built-in JEDEC low load.
