My notebook Z470 wants to upgrade the memory, the original two G, want to add 2G memory.

In the long run, I still want to add 4G, and as the hardware gets cheaper and cheaper, I may want to upgrade to 8G in the future.

In fact, for now, 2+2 is basically enough for daily use, but for a 64-bit system, the memory can be a little larger, at least psychologically, the performance is better. When the memory is large enough, you can also consider disabling the virtual memory, or using the memory to virtualize a hard disk partition to process temporary files, which is faster than the traditional processing on the hard disk and reduces the number of disk reads.

In addition, if you don't have a big financial problem and are very concerned about improving performance, you can consider upgrading the hard drive. At present, the number of revolutions of the hard disk is low, and the 7200 rpm hard disk has a certain effect on the performance improvement, as for the performance improvement effect of the hybrid hard disk or even the solid-state drive, it is more obvious, but it is much more expensive.

Your PC is Intel-based and supports asymmetric dual-channel, i.e. two RAMs do not require the same capacity. Intel Flex Memory Technology makes the combination of memory more flexible, allowing different capacities, different specifications and even unpaired memories to form dual channels, making system configuration and memory upgrades more flexible. Because dual channels are not a problem, it was not mentioned in the previous section.

Lenovo G470 can add memory modules. A single bar can be added up to 8g.

Here are the memory parameters of the Lenovo G470:

It can be seen from this that G470 has two memory slots, a single strip can be recognized as 8G, and a total of 16G maximum memory can be inserted.

If it is increased, it can only be inserted in one memory slot, up to 8G. Coupled with the original local 2G or 4G memory, it can be expanded to 10G or 12G, which is enough for general home use.

Here are the basic parameters of the G470:

Hello, but it is still recommended that you first check the number of memory slots on your computer, the brand and model of the memory, etc., and you should also buy the same memory module as your computer to ensure the compatibility of your computer with the memory.

It depends on whether you add or change.

But whether it is added or replaced, first of all, we have to clarify a concept, how much memory capacity can be used has nothing to do with the operating system, but with the number of bits of the operating system, the 32bit operating system can only go up to about the highest, and the so-called patch on the Internet will not help, so, in view of this, you must have a 64bit operating system, otherwise you can't fully utilize the 4GB memory capacity.

1.Plus, how much to add depends on your needs, but in any case, there will still be a problem that Bi Nar despises less important, theoretically speaking, if the dual-channel memory module is exactly the same is infinitely close to perfection (compatibility), the key to the problem is to say, you are very likely to not be able to buy the same memory module as your current one, brand, model, or even production batch on the market. Of course, you can also not be so demanding, as long as the brand (such as:

Kingston), the memory type (e.g., DDR3) is the same as the memory frequency (e.g., 1333MHz), and that's OK!

2.The biggest advantage of changing is that Zashi perfectly avoids the compatibility problem, but the cost of replacement will be a little higher.

.Gorgeous dividing line.

If you add it, you can buy 2GB, and if you buy it, you can buy it if you buy it, and the price difference is still relatively large.

But a 64-bit operating system is inevitable.

Dear Lenovo users, hello!

According to your description of the problem, it is recommended that you first check the number of memory slots of your computer and the brand and model of the memory, etc., in addition, you should purchase the same memory module as your computer to ensure the compatibility of your computer with the memory, in addition, we recommend that you contact the nearest service station to add, so as to avoid accidental losses caused by adding yourself.

Hello, it's okay to directly change the 4G memory.

Dear Lenovo users, hello!

Your computer can be plugged into two memory sticks, it is recommended that you first check the brand and model of the memory, in addition, you should buy the same memory module as your computer to ensure the compatibility of your computer with the memory, in addition, we recommend that you contact the nearest service station to add, so as to avoid accidental losses caused by adding yourself.
