The old driver is wearing a tender series! The old driver of Asgart answers the common questions of memory!

It is said that the old drivers like to install X in front of the master, but the old driver of Asgart's DIY does not think so! As long as it can solve the problems that most whites encounter when they are installed, let the world be full of love, and it is not a monastic. Therefore, this time, the old driver of Asgart DIY forced to dress up, recalling the memory problems that he encountered as a white time!


Question 1: Existing 4GB memory, can you directly install an 8GB of memory?



The host has a 4GB of memory inserted in it, and a DDR4 DIMM slot is vacated. Because of the recent heat of the "eat chicken" game, it needs to install an 8GB of memory, but it is afraid that the newly purchased memory is incompatible with each other. Can it be achieved? Will it affect system stability?




The answer is yes. When there are spare DIMM slots on the motherboard, you can directly access different memory modules to increase the system memory capacity. It should be noted that DDR3 and DDR4 memory are mutually incompatible. Do not use DDR3 and DDR4 memory. Even if the motherboard supports both DDR3 DIMM and DDR4 DIMM, they cannot be used at the same time.





And regardless of the frequency of the two memories, as long as they are connected to the corresponding dual-channel memory module slot, the dual channel function can be automatically turned on. It should be noted that the two memories only run at a lower memory frequency after the dual channel is turned on.

Nowadays, more people upgrade their memory modules for the "Jesus Survival: Big Escape" game. However, for users with compatible machine upgrades, it is very likely that the memory that needs to be upgraded is inconsistent with the original memory specifications. Don't worry, as long as the memory is working properly, even the dual channel function will be automatically turned on, which will greatly increase the memory throughput.


Question 2: Is it necessary to buy a higher frequency memory?



The DDR4 memory price difference on the market is now large, with vests and without vests, with and without lights. If I am neither an eye control nor a light control, is it necessary to raise the budget to buy high frequency memory?





Next, the old driver will use a single memory to do an experiment, and the memory frequency in the BIOS is 2133MHz.





The throughput of Asgard Azarcel memory is tested by AIDA64 software. The read and write at this frequency is 15666MB/S and 14871MB/S respectively.





Then the old driver locks the DDR4 memory to DDR4 1066MHz through the settings in the BIOS of the motherboard.






After testing the same software again, the memory read speed was only 8261MB/s and 7643MB/s. At this point, it is obvious that the power-down and the speed reduction that occurs when the software is turned on can be felt.

DDR4 has a higher default frequency than DDR3 memory. When DDR4 runs on DDR3 frequency, its performance is not as good as DDR3 memory with lower timing. This will greatly affect the overall operating speed of the system. If you have a good budget, buy a higher specification of high frequency DDR4 memory.


Question 3: What is the use of setting up virtual memory?




Click on the "Properties" button in the operating system and click on "Advanced Properties Settings"




Go to the virtual memory settings page via "Advanced" - "Performance" - "Settings" - "Advanced" - "Virtual Memory Change" in the pop-up window.





By default, virtual memory is automatically allocated based on system disk capacity to increase page memory capacity.




By adjusting the upper and lower limits of the value, you can move more disk space for the system page memory and use the virtual memory capacity. As shown in the figure, the page "committed" memory has increased from 9.8GB to 12.8GB. However, the total amount of memory does not change.




For the system, the memory access speed is second only to the secondary and secondary cache of the CPU. When the system begins to access virtual memory on disk, the corresponding speed of the system will decrease from ns (nanoseconds) to ms (milliseconds).

Setting virtual memory can increase the page memory usage of the system. This page memory (virtual memory) is not comparable to real memory. This is a compromise for small-capacity memory systems under Windows. Let the system not crash when the memory capacity is exhausted.

This feature is only available for applications that require less speed and less responsive feedback. Virtual memory can only reach ms (milliseconds) in access speed, and setting a large amount of virtual memory will steal more disk capacity.

Therefore, if the budget is sufficient, the old driver still suggests to directly increase the system memory. After all, ns (nanoseconds) and (ms) milliseconds are 10 e-6 in magnitude, and the experience can of course not be compared!

Well, this period of the old driver installed the tender series so far, look forward to seeing you next time!
