Ask for help on how to upgrade IBM ThinkPad R51e 18432XC memory

It's not as complicated as you think, and since you know it's DDR2, you can buy DDR2 laptop memory.

Notebook memory sockets are generally 2, and you are now 256, I estimate that only one is plugged in, so you can add one.

I can tell you with 100% certainty that as long as it is DDR2 laptop memory, no matter what frequency or size, it can be used.

However, theoretically, it is generally two memories of the same frequency and size, which is the most efficient to work. You used to be 256 and wanted to add a 1g, which is not very coordinated in theory, but it does not affect the use.

Regarding the frequency, it is generally 266,333,400 three, and you can use the CPU-Z software to see how much yours is. The higher the frequency, the faster, if the original 266, you can also buy 400 plus, but the effect will be reduced to 266, a waste. The original match is 400, and you can also add 266, but it will also pull the original match back to 266, which is not good.

Actually, it works.

I would suggest that it is better to change 2 512 ones. Or 1G, now the memory is cheaper.

Be careful enough, give me 30 points!

This machine uses DDR2 533 memory,As long as it is equipped with a 1G DDR2 533 or 667 can be,533 can not be found on several books1G,It is recommended to go directly to 667,It can be used together with the original memory,It's just that the new 667 memory working frequency has been reduced to 533,No problem。 Just note that the maximum memory that can be on this machine is only, not the official nominal 2G, only a few machines and specific batches of memory can be up to 2G

And the CPU capacity of your machine is really not enough, it is recommended that you change the CPU under the premise of sufficient funds and hands-on ability, and it is recommended to change the CPU, which is recommended to be Pentium M-750, which has a main frequency, and supports dynamic frequency reduction, which is very suitable for your machine.

PS: Now the memory of DDR2 is more expensive, and it is more difficult to find a good strip of 1G, good luck.

The Lenovo ThinkPad SL400 (27432FC) has a sleek form factor and a well-balanced configuration, making it perform well whether it is used for entertainment or business. As a ThinkPad notebook, it's also very kind. For business people who are new to work, it is best to give preference to this product.

CPU upgrade to M770, ** sold. The lowest temperature after I changed it was 47. Don't forget the thermal grease when you change it, and be sure to clean the radiator.

Friends want to test! I advise you not to upgrade! Your book is not worth it! Truth!

The CPU can be upgraded to the highest when the Centrino, but not so much for a while.

Regarding memory upgrades, it seems that this model is more picky, I planned it with my colleagues, it can support 1G+1G but it crashes after a long running time.

At present, 512m+1g is still in use

Friends want to test! I advise you not to upgrade! Your book is not worth it! Truth!

This machine is the first generation of Centrino, right? Actually, you are still enough.

At most, it's good to upgrade the memory, and there is no need to upgrade to 2G, 1G is enough.

Don't upgrade, it's better to buy a new one.

Your book that series supports 2G memory The following is the parameter introduction of the Pacific Computer Network。

If your book is ThinkPad R51E 1843AX1 then your memory is DDR2,I yesterday (just went to add a 1G Kingston's DDR2 800 memory 100,My model is R51E 1843-2XC and yours is about the same,In fact, it's the same to add memory there,As long as the memory is**,And then plug it into the machine to boot the display,If the memory is incompatible, it won't be able to boot,You can try a few more brands (as for the choice 533 667 800 is actually the same, will be automatically reduced frequency use, personally recommend Apacer and Black King Kong, Kingston last consideration)

Personally, I suggest that you add a 1g, which is not expensive in itself, and the price of 80-90 yuan is normal, but it may be low in mid-December.

Even if you're very sure of the model of the memory, you have to take the book to try it when you buy it, because there are still many problems with the memory compatibility of the notebook, and the merchants recommend bringing the notebook to try it on the spot, and if it doesn't work, change it immediately If you save it, you can change it again I think you can get a 1g strip You try it, if it doesn't work, it's 512 Anyway, now the memory is at the price of cabbage.

You can buy 667, you can't talk about less, if you are in Beijing, go to Zhongguancun to see. Look at the price from the Internet, and then you won't be deceived, and other electronic products can also be. , you are on the **optimistic**, no one can fool you.

As for distinguishing the real from the fake, look at the anti-counterfeiting signs at the back, and it is best to confirm it on the spot! @

Buy a DDR2 ,2G,800MHz memory stick,Samsung's on the line,I believe you will feel a lot better than before,512M memory to deal with the current software is indeed too little,But even if you change it, don't fantasize about being able to compare with today's general desktops,After all, the motherboard chipset and CPU are relatively old,But adding memory does have a significant increase in performance。

Hello! For convenience, it is recommended that you go to Lenovo's service station to inquire about the diagnosis of the problem, the maintenance is free of charge during the warranty period, the main components are guaranteed for 2 years, the system and software are guaranteed for 1 year, foreign licensed goods need to register for IWS global warranty, and the choice of service station can be queried:

Other questions can also be compared in the two forums, the idea forum.

Hope it helps, thank you.

DDRII memory, your model supports up to 2G, so just buy a 2G one.

This machine is suitable for DDR2 memory,Due to the motherboard chipset,The manual says that it can be up to 2GIn fact, it can only go up to I've tried two 1G and a single 2G,Unsuccessful,Some netizens on the Internet have successfully used a single double-sided 16 particles2G memory success,This machine memory has two slots, one has a special small bezel on the back of the machine,A screw can be opened when loosened,This is an expansion slot,The other slot is under the keyboard,It takes a little effort to remove the keyboard。 This A29 should be equipped with 256M memory as standard,Just under the keyboard,If you want to add memory, you can directly insert a 1G in the expansion slot on the back,Enough is not expensive。 Hope this answer is helpful to you.

with memory, so that the degree of matching is high. However, it's not that different frequencies and different memory can't work, it's just that it's very wasteful of memory sticks. For example, if the frequency of your memory module is 800, you buy a 1600 one. Then 1600....

IDE interface. 4200rpm How much capacity can you buy now, IDE hard disk can basically support how big it is...

Since it's normal to dismantle one, it means that these two memories are incompatible, so they can't be started Generally, for high compatibility, it's better to choose the same brand and the same frequency bar, and you'd better deal with the modern one in Kingston.

A single 2G 6400S has passed the actual test, and the IBM R51E is used in the personal hand.

Support upstairs. But so. I guess yours is a compatibility issue. Since 2 gigabytes of memory are supported. Go for a single 2g one. I think the stability is good.

What do I think of your DDR memory machine, how did your second-generation memory fit in?

Yes, the motherboard is with an RC410 chipset.

The maximum support is up to 2G, don't add more.

IBM's compatibility is very good, and it basically doesn't pick a strip.

Pick a long warranty to start with.
