The 02 year old computer wants to add a memory stick, and asks for some advice

There is no problem with adding 512, but your computer can only use DDR1 generation. Your original DDR266 is now estimated to be difficult to buy 266, and it is basically DDR400. It's not a big problem, though.

The 512 should now have 80-100 blocks of DDR memory.

If you upgrade as a whole, well, if you play newer games, then E5200 + P43 + 2GB memory + 4830 graphics card is recommended.

If you don't play big games, you can consider a combination of 7750+780g. The price is not too expensive. The former is less than 3,000 on the entire platform

I guess the original is 256m, right? Add a single 512m, anyway, you don't support dual channels, there is no need for the same capacity.

There's no need to add 1G, your CPU is Celeron 4 2G, the performance is really bad, and it's useless to match 8G memory.

Use a USB flash drive to copy memtest and 3DMark2001 to the local second-hand market for on-site testing, the former is dedicated to testing memory stability, and the latter is to test the overall stability.

Pay after the test!!

Good luck!

Brother, to be honest, there is no need.

First, the old strips were discontinued, and they were also old when they were found, and they were not cheap.

Second, what should I do if I don't feel ideal after changing? Continuing to change hardware?

Celeron Let's use it first. You tell me.

2G Goldbond DDR2 800MHz, it is best to use software such as CPUZ to see the CL value in the SPD, this value is better to be the same, otherwise there may be compatibility problems. If you can't buy it, it is recommended to buy two new DDR2 800 memory of the same specification, brand, capacity and batch.

If you can't do it, you can buy a DDR2 800 2G plug in, if it can boot normally and identify the capacity, use the memtest software to soak 5 6 times in a row, and if there is no error, it means that the compatibility is no problem.

The difference in frequency, high frequency, high bandwidth.

You can't get on 1600, that's DDR3, and your board supports DDR2

800MHz and 1600MHz can be seen from the numbers which is better, you can only add DDR2 with memory, the highest is only 800MHz, that is to say, it is of little significance, and the problem of compatibility should be considered, after all, it is not easy to buy 2 generations of memory now.

It is best to use the same brand DDR2 with the same frequency to form a dual-channel memory, and then the actual memory efficiency is greater than 4G

It is recommended that the landlord choose the same manufacturer as the original memory in terms of increasing memory, that is, "Hynix PC2-6400 DDR2 SDRAM 800MHz" Because the memory structure of each manufacturer is different, the use of inconsistent memory is easy to cause internal friction of system resources and problems with system logic, resulting in crashes.

If you add memory, the size can only be added at most 2G, and the model only needs to be noted as DDR2 SDRAM 800MHz, and the brand can be ignored.

It's good to buy a 2-lot one in **, 2g should be about 100. It's been discontinued, and it's brand new and expensive. Just add a separate display, HD6670, or GT640 can also be used, and second-hand cost-effective should also be considered.

I don't know what game you're playing, but if you have high requirements for your graphics card, you may not be able to add memory.

Add a 1g bar It's not expensive.,667's can be used.,When the two are plugged together.667 will be reduced to 533 to use.,If you buy 800, you can also use it, but it's an effect to use it with 667.。 Nothing necessary.

I'm also planning to upgrade the memory of this book.,I think it's best to add 1G.,If it's compatible with the original, use it together.,If it's not compatible, don't use the original.,Just use 1G!

A view, I hope it will help you!

533 667 800 are all second-generation memory, all of which are compatible!

It's better to add 1g.

My computer is VGN-SZ56 C when buying plus memory 1G yuan tax amount original).

DDR2 generation can be used for high memory frequency and low frequency can be mixed and low.

Add a DDR2 800 sliver, preferably memory technology, if you don't, Kingston can do it.

DDR3 must be used (unlike DDR2 interface, it cannot be plugged in, and there is also voltage).

As for **You'd better take a look**!

If you add memory because of slow boot and processing, it is recommended that you reinstall the system and try it! (The 512MB processing speed is also good, not to mention your pull!) )

As for the 800 main frequency and 667,The main frequency is said to be in DDR1,Now the CPU is intelligently adjusted,Generally not very particular,It is recommended that you buy memory to bring the notebook over,Try it on the spot,Then see if it is recognized in the system。

Other suggestions are best to buy memory after sales, although it is more expensive, but rest assured in the future! (The after-sales memory is guaranteed for three years, and the outside may be a lifetime warranty, but there will be no one in the second month of that stall, who do you find!) ）

It's best to tell you that the after-sales ** are all unified (unlike the outside** chaos, the quality is good and bad, because I am Lenovo's after-sales personnel, thank you!) )

You can't use DDR3, you can only use DDR. The memory of the second generation is greatly reduced because the manufacturer produces DDR3 in large quantities, so it is expensive, and the possibility of price reduction before the Spring Festival is very small.

DDR2 667 is recommended! It is very likely that it is not compatible with 800 If there is a problem, it is even worse to use DDR3 Now if you want to buy it it is better to buy it online 667 2G ** in the appearance of 180.

But it's not licensed, but it's very cost-effective, I've been buying it for 2 months, and I haven't had any problems, and I bought 1 stick of 1g 1 year ago

Now I bought a root 2g and it works very well.

If the main frequency is 800, it can be automatically downclocked to 667

Of course, you can't install three generations of memory.

The front-end bus is narrow and the second-generation memory is slow.

There's no need to toss anymore. Stick to it for two years!

ThinkPad can only buy the three series of T, X, and W, and the others are low-end fooling the Chinese.

Can't install three generations of memory! Motherboard not supported! Buy Kingston's! 200 or so to find me!

Detect with Master Lu hardware.

Some memory modules are incompatible.

Take a look at what kind of memory modules your computer supports.

Upstairs, don't say if you don't know, the interface is not the same and can't be plugged in, how to use it? It is recommended to figure out what is being used now, at least to know what interface it is, what the frequency is, if you want to have strong compatibility with the existing one, it is best to buy the same brand as the current one. It's best to buy the same one you use now.

Add memory first depends on the type of notebook memory support,If you don't like to use win764-bit system,Then the memory is enough below 4G,No need to increase memory,And the memory slots of this book are generally only 1 2,Pay attention when buying! In addition, the memory of DDR2 is difficult to buy, and ** is also on the high side. With WinXP, 1 2G is also enough.

After adding the memory module, the system runs more smoothly and plays large games.

There is no bad impact, it is all a good influence, and you can add it with confidence.
