EDIT: The laptop is five years old, not my daughter.

OK, my daughter got a new Mac and gave my wife her old IBM.

Microsoft Windows XP
Professional
Version 2002
Service Pack 3

IBM Corporation
IntelŪ PentiumŪ M
processor 1.75GHz
366 MHz, 448 MB of RAM
Physical Address Extension

As I have been trying to get it to work at something other than "glacial" speed, I sought help here:

http://www.bleepingcomputer.com/forums/ind...amp;hl=bsgranpa

One idea is to upgrade RAM, so I looked at this option:

http://www.4allmemory.com/index.cfm?fuseac...mit=Find+Memory

There is currently 512MB installed. The question is: What is optimum? Do I simply buy another 512 and double my memory? Is there possible compatibility between the old 512 and the new? Or, do I buy two new 512's so that they match. Or, do I buy two new 1G's (is 2G overkill for this old machine?) Is there a preferred memory where speed is concerned? (brand, etc.) The prices are fairly cheap and I'm not opposed to spending for two new 1G chips if that makes sense.

I have certainly appreciated the help I have received here in the past. All are very generous with time and expertise. Thanks in advance.

There are several models of the 51e that I can see, 11 variations per www.crucial.com. The Crucial site will also reflect max RAM and other data for your system.

There are various Types listed...I'd try to make sure that I get the right RAM for correct Type of R51e that I possess.

Louis, Happy New Year my friend. How do I determine the right RAM for this machine?

I would go to the above and enter the assigned data which should bring up your particular system. That would include specs.

Once you know the exact specs, getting the correct RAM should be easy.

FWIW: I would get at least 1GB additional.

Louis,

I guess that it's pretty cold in your part of the country right now. My mom is visiting some old friends in the Dallas area and I'm hearing reports of some pretty cold conditions. The info on the IBM is:

System details

Machine type/model: 1844-5GU

Serial number: LV04328

BIOS version: 78ET36WW (1.07 )

Operating system: Windows XP Professional

Operating system version: 5.01

Total memory: 512 MB


I decided to reformat and do a fresh install today and I'm pretty close to having all of the updates and programs my wife will need installed. I still think that more memory will be of benefit. Given the information above, what is the correct memory? Where's the best place to get it? Can I mix memory? In other words, can I leave the existing 512 in one slot and install the new 1G in the other? Remember, I'm the guy that is pretty much of a novice and I need a lot of hand holding. Thanks in advance.

I have this exact laptop, and yes, you can mismatch the RAM on it with no problems.

43 degrees? Cold? Bah
Try 14 degrees with a couple feet of snow

Thanks :huh:.

Lenovo ThinkPad R51e 1844 is what I needed.

http://www.crucial.com/store/listparts.asp...8All%20Types%29

If it were me, I'd buy 2GB and install both modules, removing the one currently installed. That's because I like having the max RAM on a board/system which supports less than 4GB (FWIW, many laptops today come with 4GB installed).

But you could buy just one module and install it and it should be OK.

Crucial is a very reliable RAM vendor, good customer service, good quality.

Louis

Off-topic: Mark...the high for this day here all-time is 80 degrees, while today set the low (16 degrees)...typical central Texas weather :thumbsup: . I woke up one day when I lived in Iowa...minus 46 degrees. That was cold!

Louis & MadDawg, there is a video on the Crucial site which shows how to replace one memory chip. However, I understand that the laptop will take two such chips. Are you aware of a similar video which shows how to replace two modules instead of just one. Or, can you describe step by step how to do it?

It should be the same procedure...the RAM slots should be somewhat identical and in the same locale.

Maybe not, see http://www-307.ibm.com/pc/support/site.wss...ocid=MIGR-53166.

Here is a link to very detailed service manual pdf for you laptop series
Changing memory is on page 75

http://www-307.ibm.com/pc/support/site.wss/MIGR-53169.html

Pages 75 and 80 in garmanma's link are the pages you'll want to look at if you want to change both modules.

Sorry to be so dense. What's a FRU? Does this mean that the memory modules are installed in two different places and that the second module replacement or installation requires that the keyboard be removed? Also, my wife's laptop does not have a touchpad, just a red button to move the cursor.

Removing the keyboard is a simple procedure

Thanks to all, I'll order the modules and dive in "GULP". Stand by for report. The boom you might hear, will be me blowing up the IBM (lol).
