All memory, where is the difference between high end and low end?

The most recent comment area partner has a lot of advice on memory, such as memory specifications, brand issues, and of course, the most important thing is the price issue. Xiao Bian answered a few questions, but I feel that the demand is too large. Let's put common memory today. Buy the problem and share it together.

High frequency low frequency difference!

Many people may not care about frequency, but the effect of memory frequency on performance is particularly direct. As far as DDR4 memory is concerned, the initial frequency specification is DDR4 2133, the current mainstream is DDR4 2400, the high-end memory frequency has reached DDR4 2666, DDR4 2800, and even higher DDR4 3000 (2933), DDR4 3200 memory. Do not underestimate the difference between this, not long ago, Xiao Bian pushed the election of memory yet? With APU you have to be so selected, mentioned on the memory frequency of the system performance, especially if you want to use APU installed little partner, the memory frequency is not lower, absolutely benefited!

Non-ignorable memory timing

The same frequency of memory, why overclocking memory is more expensive than ordinary memory? In addition to the cool appearance, the most important thing is the difference in memory timing to cause this result. The so-called memory timing, memory timing is a parameter used to describe memory performance, generally stored in the memory SPD chip.

There are 4 important indicators of memory timing, namely CAS Latency memory delay, RAS-to-CAS Delay memory row address to column address delay, RAS Precharge Delay memory row address strobe precharge time, and Row Active Delay memory row address strobe delay.

It sounds complicated. In fact, they basically measure the memory latency problem. Of course, the shorter the number/period, the higher the memory execution efficiency, but this specification needs to be preset in the memory (SPD chip), and then the system calls these settings. Good parameters. Why do you want to do this? That's because these specifications are generated based on the "physique" of the memory chip and are not arbitrarily set. Therefore, high-end memory usually uses better-quality particles for smaller delay performance. Therefore, if you are concerned about performance, then you must understand the delay performance of memory, high-end memory is usually rely on this part of the difference to reflect the value.

Coolest LED useless high end logo

It must be said that the development of memory in the past two years is also a bit of a tendency to go. In addition to Xiaobian said the difference in performance, there is the quality of the advantages and disadvantages. However, it has now grown to a stage where there is a need for a breakthrough in appearance.

A lot of memory not only has a very cool heat sink decoration, and even added seven colorful LED lights, this light pollution Xiaobian even disapproved. However, many people like it very much, especially the kind of open chassis, side panel hollow transparent chassis, it is really cool to install LED lights.

However, Xiao Bian really does not recommend simply because "beautiful" to buy memory, a high quality, superior performance of the memory is the most fundamental, eating chicken and the like to eat memory applications, games can be good or bad, regardless of memory Oh!
