RAM

[chrbb]

Why is adding RAM so difficult? Got 4 laptops with 256mb ram, so decided to add 1gb ram, I muck up and only order 3, so I thought I would simply take one stick out of one of the laptops and double it up in the fourth.

 

Open up laptop, take out old ram put new ram in, won't boot - 3 beeps, so open up laptop replace old ram take out new, laptop boots. Laptop will only accept new ram if I add it to the orginal ram:mad:

Running the latest BIOS version? sometimes that makes them more accepting of larger RAM chips.

Your're not calling me a chap are you:)

 

Fujitsu amilo pro v2055 current ram pc4200, new ram pc5300, it worked in the end but only if I left the orginal stick in as well. Irritating and puzzling more than anything else.

The BIOS may not have been able to figure out the memory timings properly from the SPD information on the newer chips or as with some memoery controllers there may have been a restriction on using larger RAM modules without fully populated sockets. Happens with some servers to.
