In the past two years, the computer hardware has steadily climbed two big slopes, the original 2,000 yuan war 3A, 5,000 yuan high-performance mainstream configuration, now only enough for the entire online game family barrel.
But at the same time, the threshold of CPU, graphics card, SSD and other hardware has become very low, as long as you can compare the size of the number, you know that the 3090 is stronger than the 3060.
One penny for one penny, three cents and two goods, having money is to do whatever you want, and you can get higher performance by adding money.
But so far the memory of this thing is still a special case, 3 cents is really not necessarily comparable to other people's 1 cent, knowledge is wealth is not wrong.
01
Performance gaps
The memory is small, and the price is much cheaper than the CPU and graphics card, but it can greatly affect the overall performance and use experience.
From the test data alone, it is mainly bandwidth and latency.
There is a clear difference in frequency and between single and double channels.
The performance gap on the same set of platforms varies from scene to scene, but for many places that eat memory and eat CPU, it is a world of difference, and the more high-end graphics cards, the more obvious.
Then according to the law of the market, the more expensive it is, the higher the frequency and lower timing, isn't it enough?
But this is not the case in reality.
02
Actual state
Expensive does not equal good, mainly because what you buy is not equal to what you use.
When we purchase memory, we can basically see that the memory is marked with the parameters of capacity, frequency, and timing, such as:
But it is not necessarily at this frequency and timing when plugged into the computer, and the actual state you can view through software such as CPU-Z.
And most of the memory needs to be put into the motherboard BIOS to set XMP, or even manually overclocked.
Many small whites do not dare to move the options and values inside, even if there is a certain foundation, only few people can adjust the memory to a better level.
Plug in and use directly, no matter how good the memory is, it can only run according to the JEDEC specification, and the actual frequency is 2133-3200Mhz.
So the good memory that you spend a lot of money to buy is blind!
Why can't Auto be like a CPU or graphics card? It's 2022 and it's not smart at all!
Oh, and there is XMP ?
03
XMP
JEDEC this specification is really crotch, all 2022 DDR4 up to 3200MHz, timing is very loose.
Therefore, many memory has added XMP, that is, the manufacturer presets the operating frequency, timing and voltage different from JEDEC.
When purchasing memory, the XMP parameter is actually marked, and this function needs to be enabled to achieve it.
Called XMP or DOCP in the motherboard BIOS, it is recommended that everyone should learn how to turn it on:
This thing is good, but the general memory is only 3200MHz, and it is more than a little expensive.
Moreover, the high frequency of the target is not necessarily good, and it is not worse to spend more money on performance?
04
Differences in physique
The root cause is that there are very big differences in memory constitution.
Even the particles also have a lot of brands such as Samsung, Micron, Hynix, South Asia, Changxin, etc., and they also have B-Die, C-Die, E-Die, CJR...
There are dozens of particle grades, how many people can figure them all out?
Because of the production details and market profits, most manufacturers do not always use a specific particle for the same model of memory.
Their frequency timing and voltage are very different, even if you write XMP in batches, you can't get busy.
Even lazier manufacturers don't even bother to write XMP, the default 2666MHz is finished.
So most of them just need to keep a bottom, want to be high? Pick it up for you, but you'll have to add money.
05
Conclusion
In general, the difference in physique and the reluctance of manufacturers to be careful caused by memory XMP is not as smart as CPU Turbo and Graphics Card Boost.
This also leads to the fact that most people can play 90% of the strength of the CPU and graphics card, but in the era when memory can generally run to 3600 and 4000, how many people exceed 3200?
The threshold for memory is too high, and it will basically not change in the future, especially high-end platforms are more likely to waste the performance that should be there.
Therefore, when considering high-performance CPUs and graphics cards, you can't ignore this little thing, think about whether you have strength or financial resources.
