View Full Version : Satellite Pro 2100 - not functioning with two sticks of RAM

19.04.2007, 11:42
Hi all,

I have been provided with 2 x 512MB sticks of RAM from a reliable supplier that reassures me that this RAM is compatible with the SP2100 laptop.

With both sticks installed, as soon as the machine is switched on I get no display and 5 beeps (1 long one followed by 4 shorter beeps). Each stick of RAM works well individually, and I have also tested slot A and slot B. So, both sticks of RAM are working alone and both slots are working. It seems that this machine has a problem with two sticks of RAM.

The ACPI BIOS is up to date (v1.40). I have also tried the old stick of 256MB with one of the new 512MB sticks - same problem. I tried this as the memory supplier mentioned that this Toshiba can only take 1GB maximum.

Any ideas why two sticks of RAM is not working?

Thanks in advance and kind regards,

You are right…. The notebook should be able to handle the 1024MB memory. (2 x 512MB)
Because of your description I think the both modules are compatible but cannot play together….
In my opinion you should use both modules with same specifications…

Try to use the modules recommended by Toshiba;
PC2100 256MB (PA3127U-1M25)
PC2100 512MB (PA3164U-1M51)
