It may be possible that the memory that you are trying to use may not be completly compatible with the architecture of the motherboard, if you are using Win XP SP2 you will need a minimum of 512 Mb mem otherwise it will run slowly (especially if running norton AV or Mcafee AV)

It would be a good Idea to buy replacement memory, as the compatibility of the memory you are trying to use is in question.

Kingston memory have a "configurator" which ensures that you get the correct memory for their board, and their memory has a lifetime warranty.

I wanted to extend the RAM of a Laptop Toshiba Satellite S1400-503 (approx. 10 years old) from 256 MB to 2*512 MB (PC133) but the system doesn't start. Only various beeps with dark screen occur. I read...

You have the last bios they made for that machine. If the original memory will still boot the machine, one or both of the memory modules you are using are not compatible, defective or not seated correctly. If not you have some other problem. Not all PC 133 chips are created equal. Check the manual if you need to; . You can try replacing the original chjp in slot A and one of the new chips in slot B sometimes that works but you may have stability issues if the new chip is not 100% compatible.

My pc was working fine with 128 + 256 ram. few days ago it didnt was restarting automatically. then i removed 256 ram and it booted normally.means pc works normally with 128 ram but not with 256...

i guess u have 2 different RAM cards in the RAM slots....
the main issue is both dont work together...the primary reason is compatibility....or one of the RAM cards have worn out...
u must use exactly similar kind of RAMs in both slots....
i suggest u use one 512 MB if your motherboard supports....
RAM technology has advanced so mush that you wont get RAMs for old PCs (motherboards) u decide...
pls revert back...and kindly leave a feedback and rating for this will help me move to Guru" here from Expert at Fixya....

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.

I have problem about ram

If the manual says this motherboard support up to 1 GB RAM, you cannot put 2 GB. You can put 2x 512 GB RAM or 1GB RAM
Also try to upgrade your bios, maybe a better bios version supports more than 1 GB RAM.

Well i have a compaq presario 1700 XL360 it came with pc100 64 memory ram i tried to upgraded with two 256 memory ram to bring it to total 512 mb thats the max for this computer ...

There is a good chance that your system needs a firmware upgrade in order to recognize the bigger memory. I found one in this page

Be carefull and follow the instructions since you could brick your system.

If that does not work, do not expend more money in that system (very old), just save to get a new one.

P.S. The memory you got is the right kind.

Good luck

Unable to install Windows xp

If you can afford it i'd look at trying another stick of 256 or a new 512 stick, XP doesn't really like anything under 512 and it pretty much won't run at all with 128, so if you can get it cheaply try that first if that doesn't fix it let me know
