Question about IBM ThinkPad R31 2656 Notebook

1 Answer

RAM chip sets

When upgrading the RAM chip size from the original installed 128 MB to say 512 MB does this need to be done with:
* 2 x 256 MB RAM chips [a matched pair] OR
* 1 x 512 MB RAM chip [single chip]  thus allowing you to add a further 512 MB at some later stage to increase the RAM to the allowed maximum of 1 GB??
Many thanks

Re: RAM chip sets

It is OK to mix chip (SODIMM) capacities in the 2 slots in your notebook.

The best system performance will be when you have 2 x 512MB but for now if you install 1 x 512MB, you could even leave the old chip in the other slot, it'll be fine.

How can I upgrade/improve the capabilities of my Inspiron 1200

The best and quickest improvement is to add more RAM. Add another 512 Mb of RAM. If you already have a 512 Mb of RAM module then add another 512 Mb RAM module. If your laptop has 2X256 Mb RAM modules then you need to remove these and insert 2X512 Mb RAM modules.
The reason why you have 504 Mb RAM is that the video card has grabbed 8Mb of RAM off the main memory.

I would like to nwom how much of memory this laptop support

The Thinkpad is installed with 128 MB SDRAM is standard, and is expandable to 512 MB
There are two memory slots, to expand it to 512 Mb you need two 256 Mb RAM modules and throw away the 128 Mb RAM module, but if you don't throw away this module and you insert a 256 Mb RAM module in the 2nd memory slot then your total memory would be 384 Mb.

Change ram from 512 to 1 gig bios cannot read added ram

The original 2 sticks of 256 Mb of RAM gives you a total of 512
Mb of RAM. Two 512 Mb of RAM gives you a total of 1 Gb of RAM.
With two sticks of 512 Mb of RAM are you sure you got a total of 192 Mb of RAM, this is a lot less than the original RAM total of 512 Mb?
Should this be 1920 Mb of RAM?
If this 192 Mb is correct then the RAM modules are either not compatible with the laptop or if the RAM modules are not from the same manufacturer then they may not work together.

Most laptops have video cards that use part of the main RAM for video RAM, that is why the available RAM is less than the installed RAM modules. The amount of RAM the video card grabs depends upon the type of video card and in some cases the amount of video RAM can controlled in the BIOS setting.

How to upgrade a Dell Latitude CPX - Intel P3 500-650 laptop

I have a CPX H500GT. To get it to run XP Pro to run right, max out the ram. And get a larger harddrive. Xp uses a substantial amount of space.

Getting access to bios in Dell Inspiron 1300

No, The amount of RAM the integrated video uses is dynamically adjusted depending on the loading of the video and the total amount of RAM installed.

If less than 512 MB RAM, the video is limited to 64MB, 512 to 2 GB max video RAM is 128 MB.
