Preamble:
Looking at the current CPU performance, in addition to productivity users, the vast majority of people have excess performance, just the performance is good, the headache is the heat and power consumption make users annoying, especially the intel 13th-14th generation Core processor is the most prominent. The toothpaste factory Intel is not without a solution, and the joint motherboard manufacturer has given 104 microcode, and the user can use the BIOS with 104 microcode to automatically decompress the CPU after setting, thereby reducing heat and power consumption. Recently, intel updated the microcode to 0x123, adding the 14th generation K processor to turn off the CEP for voltage reduction, today Ah Lu will use the i5 14600KF in his hand to see how the effect of the 104 microcode is.
Introduction to the test platform:
First of all, you need a 13th and 14th generation Core processor, with the K suffix to be overclocked, after all, this kind of CPU power consumption and heat are the most headaches.
The motherboard uses MSI MPG Z790 EDGE TI MAX WIFI, the outer packaging of the motherboard looks good, and the black font below the square grid fragmentation model + gives people a strong sense of digital.
MSI MPG Z790 EDGE TI MAX WIFI has a nice visual effect with the black PCB.
The CPU power supply and cooling module has added MSI's iconic Dragon Soul LOGO trim plate, which has a glossy design, and RGB lighting effects can be seen when the motherboard is lit.
In terms of power supply to the motherboard, it adopts a 16+2-phase Duet Rail configuration, and the materials used in DrMOS are worthy of the price of the motherboard. Among them, the 16 phases can withstand a maximum current of 90A, and the 2 phases can withstand a maximum of 75A current for the core display.
The memory frequency of the MSI MPG Z790 EDGE TI MAX WIFI can soar up to 7800MHz+, and if you encounter a CPU and memory with good physique, it is believed that it will be a drizzle at 8000MHz.
Since the first M.2 interface is directly connected to the CPU for communication, it supports PCIe 5.0 m.2 SSDs.
The first M.2 heatsink also comes with a tool-less quick release device, which is convenient for gamers to disassemble and assemble.
A total of 5 M.2 SSD ports, the first one
It supports the PCIE5.0 protocol, and the remaining four support the PCIE4.0 protocol.
Realtek ALC4080 sound card,Surrounded by 7 liquid audio capacitors,There is also a special signal isolation belt next to it,If you are not a music enthusiast,Then I think it is enough,Drag the speaker within 500 yuan to sprinkle water。
There are all the I/O interfaces in the back, video output interfaces: DP 1.4, HDMI 2.1, 4*USB 3.2 Gen 1, 4*USB 3.2 Gen 2, 1*10Gbps Type-C, 1*20Gbps Type-C. In addition, the two buttons that look like Peppa Pig are used to clear the shortcut key for CMOS settings and the shortcut key for refresh BIOS without U. RJ45 wired network port rate is 2.5G, WiFi7 wireless network card interface and 6*3.5mm audio interface, and there is also an SPDIF interface for transmitting digital audio.
Tutorial:
1. Update the BIOS
Download and update the motherboard BIOS from MSI's official website, as shown in the picture above, pay attention to the overview of the new version of the BIOS, and mark the update CPU uCode version 0x123. For more information on how to update the BIOS, please see the detailed tutorial on the Alu homepage.
2. Set IACEP to Suppress
lA CEP Support For 14th和GT CEP Support For 14th两大选项均设置为禁止。
3. Set the CPU overload line calibration mode
For players who often overclock the CPU, you may already know that the CPU voltage is not constant, it will change with the load, and the CPU load line adjustment is to set the anti-voltage drop according to the high and low load of the CPU.0x123
Generally speaking, Alu recommends setting the load line to Mode7 and 6, and if it is a large eagle level CPU, you may wish to try Mode8. In addition, you need to set the CPU Lite Load Control to Advanced, then set the value of the AC Loadline to 1, and finally press F10 Enter to automatically restart the job.
Temperature & Power Test:
The default BIOS state, no 0x123 microcode enabled, a single FPU roasts chicken for 3 minutes, the average CPU temperature is 83.7°C, the average voltage is 1.168v, and the CPU power consumption is 175.21W.
After turning on the 0x123 microcode, it is also FPU single selection roast chicken for 3 minutes, the average temperature of the CPU is 70.3°C, the average voltage is 1.126v, the CPU power consumption is 143.45W, the power consumption is reduced by 30W, and 0x123 the temperature is reduced by 13°C.
Performance Testing:
Default state
0x123 turn off CEP with microcode
Judging from the CPU-Z test results, there is not much difference between the running scores of the i5 14600KF before and after it is turned off, which can be said to be the error level.
Default state
0x123 turn off CEP with microcode
In the vray test, the running score after turning off CEP is even higher than the default state, and it seems that the effect of depressurization and cooling is still very beneficial to the performance improvement.
Default state
0x123 turn off CEP with microcode
In the CineBench R23 test, there was little difference between the before and after bucks, and it can be said that CPU performance was largely unaffected.
Summary:
I have to say that this 0x123 microcode is turned off CEP is really a good thing,Let the 14th generation Core with K processor have a significant cooling and power reduction effect when the processor is fully loaded,You must know that Ah Lu only uses i5 14600KF,Power consumption reduction is as high as 30W,Cooling down13°C。
Just imagine that the temperature and power consumption are higher, i7 and i9 processors with K believe that the cooling effect will be more obvious, and there is no reduction in CPU performance, it can be said that it has achieved the best of both worlds. If you want your 14th Gen Core to play cold and quiet, and play high performance, hurry up and update the BIOS to try.
