Urgent ThinkPad Memory Hybrid Dual Channel

It is possible to form an asymmetric dual channel (the frequency and capacity of the memory do not have to be the same.) Chips above 945 support asymmetric dual channel, if the frequency of the two memory is not the same, the frequency of the high frequency is reduced), the total memory capacity is 3G, of which 2G is dual channel, that is, 2G There is 1G and another 1G in the memory to form a dual channel.

Dual-channel has improved the performance of both CPU and integrated graphics cards, especially the performance of graphics cards!

Landlord: I have mentioned above that the total memory capacity is 3G, generally speaking, that is, the performance of your computer's memory is equal to 2G dual-channel plus 1G. The 1G that didn't form a dual channel was not wasted!

No. Dual-channel must be the same size of memory... It doesn't matter how often it is. The motherboard can be adjusted by itself. ·· It's just that... Size.. The size is not the same, and there must be no double channel. . .

2g two is better...

2G+1G is automatically dual-channel, of course, this is asymmetrical dual-channel. You don't need to do any more settings, just plug in the memory.

The memory can be dual-channel, but the motherboard needs to support it. However, it is better to have the same memory, that is, one brand, the same frequency, and the same size.

2G+1G, don't play games, don't run large-scale software, it's a waste.

Let me tell you that you can use dual channel, which is called elastic dual channel. The only reason is that you are on the platform, and AMD can't do it.

After plugging in (usually plugged into the same color slot, you can look at the motherboard manual), it will be automatically generated.

1g+2g is of course better than 1g+1g.

The same,Notebook dual channel is not so obvious,If you already have a strip,Of course, the bigger the better,If it's 1+1 now,Just use it,,It's enough,Even if it's a 4G strip,The overall performance is limited by the hard disk,The speed can't go up,Unless you can do an array like a desktop。

Generally speaking, motherboards not only dominate the CPU levels supported, but also the types of memory that can be matched. Going a little deeper, it's all due to the chipset used in the motherboard, which is designed to make the memory and CPU work closely together to get the most out of it. Therefore, in order to prevent data congestion when the CPU accesses memory, increasing the transmission bandwidth is the most direct solution.

In fact, the memory bandwidth is closely related to its operating frequency, and the transmission bandwidth will increase with the increase of frequency, so the concept of dual channel came into being, and the circuit design of the Northbridge chip can be directly modified and the current memory specifications can be used to achieve the effect of bandwidth multiplication.

In fact, the advantages of dual channels can also be explained numerically, for example, DDR2-667 memory, another way to mark is PC2-5300, "5300" refers to the memory transfer bandwidth, and the same is true for DDR (e.g., DDR400 is equal to PC3200). With the blessing of dual channels, the bandwidth will be ** to 10600, which is twice the original one, which can naturally effectively improve the performance.

You can install a memory module by following these steps:

1.Start by preparing your tools, including a screwdriver and memory.

2.There will be a mark on the back of the notebook with a memory compartment, of course, different models and different brands of notebooks will be different. But it's all pretty much the same. Be careful not to make a mistake, and if you are unsure, it is best to check the manual or consult a professional.

3.After opening the lid of the memory compartment, adjust the position of the notched part of the gold finger of the gold bar to align it with the fixed protrusion of the slot, which is actually a foolproof design in industrial design.

4.Then insert the slot at an angle of about 45 degrees, and with a light tap, it will make a "pop" sound and snap into the slot. If you don't hear a sound, it's probably not installed properly and needs to be reinstalled.

5.After the installation is completed, close the back cover, and then tighten the screws with a screwdriver.

Hello, Lenovo ThinkPad T420 series laptops support dual-channel memory technology, you can install two memory modules to build dual-channel, it is recommended that you choose a model with the same frequency specifications for both memory installations.
