Foreword: Hello everyone, this focus is on DIY computers. Share the tips and pain points of assembly, I hope to provide you with a reference and avoid detours. It's cool for a while, it's cool all the time, so let's take action.
Pre-course materials:CPU, memory, motherboard, all three together determine overclocking. The constitution of the first two determines the upper limit, which is probabilistic. Either you are lucky, or you can pick a good physique second-hand. Buy a high-end Z board for the motherboard, the more expensive the better, and double slots are better than four slots. Priority APEX, titanium carving, the cheapest should be MSI Z790i (the scalability is not very good).
The core idea is: to control the IMC (memory controller) stability. Regulates 3 voltages (SA, IVR, MCV). IVR and MCV are the names of ASUS motherboards, while other motherboards display VDDQ and VDD2.
The role of the SA is to assist in the operation of the IMC;Pressurize when the imc temperature rises unsteadily. SA is directly related to the control of IMC and can improve the temperature resistance of IMC. However, SA cannot be pressurized indefinitely, and it is also a circuit that will overheat, and if the voltage is too high, it will be unstable. Usually given less than 135, given the high risk of "shrinkage".
The relationship between IVR, MCV, and hyper memory is as follows: the higher the IVR and MCV, the narrower the range of SA values.
The constitution of the memory, like the constitution of the CPU, is a difference in the production process, and it is an innate ability that determines the overclocking ceiling.
At present, there are many batches of D5 memory particles from various manufacturers, and on the whole, Hynix A-Die overclocking performance is the best.
The HOF Pro 7000 strip in this article is made of this kind of granule. One key to turn on XMP 7000 C32 145v。Adopt the classic 10-layer reinforced PCB, all-metal vest heatsink.
HOF Pro is the flagship memory product of the Filmrun Hall of Fame family. Continuing the classic all-white color scheme, the appearance is very high. Even the PCB of mine is white, which is suitable for users of white sea view rooms. It is said that the 8000 frequency uses a black PCB.
The shape of the vest is angular, giving people a very tough and strong feeling. The surface of the metal heat sink is electrophoresis process, and the color is smooth and uniform. It is well made and feels very compact.
There is a crown logo on each side, which is a unique symbol of the Hall of Fame, which increases the dignity and recognition. The front and back sides rotate symmetrically, and no matter which side you look at, the crown is always on the right.
The outer packaging finally got a very formal hard box!You can see a slightly raised magnet from the side, yes!It's a magnetic clamshell design. The memory is inserted vertically in the cushioning foam. It is worthy of the flagship product, and it pays attention to details.
RGB: There is a light guide strip at the top, and there are also through-type light strips on both sides. In addition, the crown is also illuminated. You can take a look at the gif**, it's still pretty beautiful.
I tried ASUS's Shenguang Sync, and it was perfectly compatible. Just install ASUS Altron software, no need to install third-party software. I haven't used MSI and Gigabyte, and I am said to support them.
The gold finger is equipped with a protective strip.
Core configuration: SP only 69 14700kf;Relative to entry-level (mid-range at best) Raptor motherboards ROG Z790-F;Gujia 360 water-cooled T5;Shadow RTX3070 Xingyao. This configuration is available to most people, and it still has a certain popularity.
Step 1: Touch the imc physique. Pull up the memory frequency, other auto, and try again if you can turn it on. My 8000 is not very good (blue screen, card boot), which means that the limit of CPU IMC is almost here.
Step 1: I start with 7600. Usually 400 600MHz higher than XMP is easy. Try it as a starting point, and then slowly go up. Initially, the wide timing C40 is set, and the memory voltage is given to 155V is enough, so that the two of them are basically excluded, and the interference of overclocking.
Step 1: Initial SA. Usually at 12~1.3. Try it between them, and you can turn it on. I casually gave a 126 done.
Step 1: Find the IVR and MCV voltage combinations. Referring to the automatic value, I manually gave the ivr 135, MCV gives a 14。
Enter the system and run TM5. If you can run for more than 20 seconds without reporting an error, it's fine. Don't panic if you report an error in seconds, it's impossible to get it right. We re-modify the IVR and MCV and increment it up by one stop.
Example: I started with (IVR and MCV) 135 and 14 no, change 136 and 141 not yet, then 137 and 142...Re-139 and 144 found that it was okay.
Then hold the second one (MCV) and reduce the first IVR by one gear. 1.38 and 144 found that it is also possible, and then subtract one gear 137 and 144 Not again. Change it back to 1 right away38 and 144。
Then subtract only the second, 138 and 143, found out that it didn't work again. This makes it possible to determine that the IVR and MCV voltages should be 138 and 144 this combination.
When adding and subtracting, each gear is not all 001, such as appearing 144375。It doesn't matter, we add it according to the file. It's all 001 is just for ease of expression.
Step 1: Correct the SA voltage. Once we found the IVR and MCV combinations, we had to increase the SA voltage so that the TM5 could run the full 3 laps. Start with the SA set at the beginning of the step and add 0 each time01, but don't exceed 135v。I tried 128 And he was finished.
If you can't stabilize no matter how much you try, no matter how much SA gives, it means that your physique is not enough, and it is recommended to reduce the frequency and start again.
Step 1: Modify the memory voltage and timing. The memory voltage is not much related to the three major voltages (SA, IVR, MCV) that I explored before, and I gave C40 1 at the beginning55V, which is more broad, is to exclude interference with overclocking. Finally, we fine-tune and find the right point.
The relationship between memory timing, voltage, and frequency is as follows:
Timing affects latency, and the smaller the timing value (tightened), the better the memory performance. But the memory voltage is too high.
The higher the voltage, the higher the temperature. High to a certain limit, overclocking fails.
The higher the frequency, the higher the transmission efficiency. But the timing has to be adjusted to a larger level, otherwise it will not be stable.
So the three of them are in a relationship of mutual control. We need to find a state where the timing is as low as possible, the frequency is as high as possible, the voltage is as low as possible, and the temperature is controllable.
For example, my set of HOF Pro 7000 memory modules can be 7600 C40 15v。But C34 requires 155V, C32 may need 16V or more. In the end, I chose C34 as the best.
Step 1: Optimize the running score (AIDA64 memory performance test).
The above screenshot is an overclocking reference, interested friends can copy in the reference, and do not enter the reference, before and after a comparison. After entering the small ginseng, the AIDA64 running score will be higher, which is considerable. Ginseng is also one of the means to improve efficiency.
XMP is the official engineer's unified overclocking parameters, it is clear that it does not move much, the settings are relatively conservative, and the purpose is to make 99% of users can use it stably. Let's compare the difference between XMP and my manual one.
Official XMP 7000 C32-42-42-112 145V (the bottom).
Read: 120g Write: 116g Copy: 114g Delay: 559ns
My manual 7600 c34-44-44-58 155V (top).
Read: 105g Write: 93g Copy: 96g Delay: 653ns
This performance improvement is enough to pull outHow much has it improved?It can be calculated. After that, you can go to the post bar to dry the fruits of your labor.
After overclocking, it is recommended to run more other software and games, and test it for a few more days to see if it is stable. If the Blue Screen of Death doesn't happen, it's no problem. If there is a problem then go back to the BIOS fine-tuning.
With the highest resolution of 2K, Mind Killer 2 can run 60 frames, and Battlefield 2042 can run more than 150 frames. The two games that I just entered recently, e-Bao Winter** is really good!
Take a look at the temperature. SPD Hub is a chip on memory, and the temperature is not equivalent to memory particles, but it can reflect certain rules. There is no relevant temperature control chip on the memory particles, and can only be evaluated by referring to the SPD. I don't think it's too much 50 degrees, the lower the better.
XMP 7000 (top), SPD Hub up to 19;
Manual 7600 (bottom), SPD HUB up to 30.
It can be seen that the temperature is an upward trend with the operation of overclocking.
Step : Explore the possibilities of 7800 and 8000. At the beginning, 8000 boots on the blue screen, so there is not much left of the range. 7800 give it a try. The general trend is to increase IVR, MCV, SA, and memory voltages. Repeat the previous steps. Direct result: 7800 c36 158v。sa 1.3、ivr 1.39、mcv 1.45。Read 122g, write 119g, copy 117g, latency 566ns。
The visitors who can see it here must have their own feelings. Overclocking is all about finding the right balance between performance and temperature. Create conditions to optimize the indoor temperature, chassis air ducts, and radiators. Or add a fan to the memory. Like this bracket PDD is less than 10 yuan, just use the idle fan, and the effect is very good. In practice, winter will be better than summer, and an open case will be better than a closed case.
What is the benefit of memory overclocking?
On the one hand, it is possible to increase the average frame rate of the game. Especially FPS games that frequently rotate the perspective (such as CSGO, Life and Death Sniper 2), about 5% to 10% higher. Large-scale single-player games, on the other hand, don't have a big impact.
Overclocking, on the other hand, improves an individual's understanding of how a computer operates. Unleash performance beyond XMP with personalized settings. Explore playability with different hardware configurations.
