IBM R51 was originally equipped with a 256DDR strip, I think it s slow, I want to add, how to add it

There will be no problem with different sizes of installation, the main thing is that the frequency must be the same.

As for dual channel, simply put, it is two memory sticks, if the dual channel is opened, it can increase the speed by about 30 compared with not opening it, and the landlord should use cpu-z to check the frequency of the memory first.

This type of memory is now more difficult to find, the key is DDR 333 strips, which are rarely sold, if you can't find DDR333, you can install DDR400, because this can be used for frequency reduction, it is recommended that if you buy it, buy a large enough one, and don't use the original one, so as not to cause compatibility problems. The dual channel is not as effective as you think, in fact, it is just a concept, and it is almost the same to use, anyway, I don't feel it.

Dual-pass or not-double-pass is actually not important, add two DDR 333 512 strips, the motherboard does not support dual-channel motherboard does not support dual-channel It seems that it can't be installed with asymmetrical memory, install DDR400.

Let's use a strip of 400! For the R51 machine, you add 1 strip of 1G, and it is enough to use the XP system.

DDR 333 is very rare now, MS is not cheap, right...

Forget it directly on a 512.,It's not useful if the memory is large.,The others can't keep up.。

Yes. In 2004, Lenovo acquired IBM's personal computer business.

For the first five years, the IBM logo can be used.

After 2009, Lenovo will not be able to use the IBM logo, only the ThinkPad will be able to identify the IBM ThinkPad R51 during that time.

ThinkPad notebooks were originally IBM's business and were later acquired by Lenovo, so now all ThinkPads on the market are Lenovo products.

IBM notebook thinkpads have been sold to me Lenovo, although there is still an IBM logo on it, which is actually Lenovo,

Yes, IBM sold the PC division to Lenovo in 2004 along with the ThinkPad trademark, and at the same time agreed that Lenovo would use the IBM trademark for 5 years.

Dear Lenovo users, hello.

What you mentioned is a product that can be used with confidence.

Enjoy using it.

Man,Give it to me.,I'm engaged in repairing notebooks myself.,And I'm also using IBM R51 How to say it.,I've increased to 2G memory.,And 2M CPU performance is not very stable.,Because his voltage is different.,So if you want to add memory, I recommend up to 1G.,You're DDR 333,This R51I've used it for more than 1 year without any problems.,It's good.,Keep using it.,It's just that Zhang's is not very good-looking.,It's a little heavier but affordable.。

You can add DDR memory.

DDR400 and DDR333 are fine.

The maximum can only be added to a single 1g.

As long as it is the ** memory of the big factory brand.

You don't have to worry about memory compatibility.

The maximum can only add a single 1G It is recommended DDR400, don't go to the after-sales to buy the original version if you have money, one or two thousand one, it's too dark, just buy a general one. Remove the battery with 6 unmarked screws on the back and remove it. Then you can drag and drop the keyboard, be careful of the wired connection, take down the cable, you can see the memory location, just plug it in.

Memory module is now the most popular second-generation memory module on the market, I don't know how big your original computer is the memory module, just tell you not to go outside to add memory sticks, some black merchants are very disgusting, will give you fake memory sticks (especially for Kingston brand) and sell you the price of real memory sticks, so be careful, find someone who understands a little bit to accompany you, you will suffer less, confirm the authenticity of the memory stick, hehe, good luck! ~~

It's actually quite simple

Hehe,I'm using R51 now, and the office can be low, and the graphics card is relatively low, and large games are definitely not good.

Like Red Alert, no matter how small the Fantasy Journey to the West, it's no problem to watch something again and again.

All IBM R51 memory upgrades are up to 2G, but if the R51 machine is added to 1G, it is basically easy to use, there is a 512 in it, and then add a DDR-333 512M on the line, buy a second-hand one, add a Samsung is better, if you can't find Samsung, other brands can also be used, as long as it is compatible, it is necessary to be original (that is, disassemble the machine), it is never recommended to polish the strip (OEM), the grinding strip is made by itself, or it is OEM, There are usually instability or blue screen appearances.

I'm also R51.,It's just 2888.,Depressed.,I don't know if you play games.,I added a 512.,It seems to be able to add up to 2G.,But I think it's enough now.,I'm not adding Samsung.,It's a 333 DDR that I bought in the computer market and added it.,It doesn't seem to be anything.。

The general win7 driver can be used with vista. Or you can find out your WLAN model directly to the WLAN card manufacturer**. In Lenovo official is not available,Because this machine Lenovo Department service win7

Win7's own driver can,It's you don't know how to use win7 yourself.。 I've also encountered the same problem.,You better explore win7.。

The highest CPU upgrade of this 855 motherboard is Intel's, with a clock speed, L2 cache of 1M, and a front-side bus of 400

The electronics are updated quickly, and there is no need to upgrade this notebook. If the memory is small, you can add a memory module.

See if it's touched if it stays original and it's not very expensive.

I'm using the R51 right now and it feels good.

The game office is good and very stable.

But if you want to play a big game.

Or buy the latest configuration, after all, this is a very early configuration, and there is a point, this computer is very heavy, and it is comfortable to carry a backpack when you go out, hehe, I am afraid of its weight.

After all, doing business outside is still walking on your legs.

I just bought recovery software in ** and restored the factory settings.

It feels very good The battery is on Broadway on Zhujiang Road, I bought a new one for 250 yuan, and after a few days, I took the original battery to Shanghai to exchange it for 120 yuan for Sanyo Core.

AutoCAD should work. 7500 is still a little old, it's better not to buy it. If you buy, try 1k3?

It's a very old notebook, and the price is still high.
