I recently inherited a Dell Inspiron 1525 Notebook. I know it old but other than being slow it seems to run great. I have been looking at a RAM upgrade, but I am a bit confused about which Type of RAM I can use.
I ran a CPU-Z and got this info about the existing RAM...
Memory SPD

This is an older machine and I don't want to put a lot of money into it and I am not afraid to buy used sticks. I just want to make sure what I buy will work.
Thanks for any help, Rich

Since that laptop maxes out at 4GB, and you've already got 3GB, you won't gain a whole lot (maybe another 200-400MB) by replacing the 1GB module with a 2GB module. If you do go ahead just make sure that you match the specs on the existing 2GB module.

I'm with ex on this. doing a ram upgrade wont do much for you. Im sure its running a 32bit os so max ram would be 3.2-3.4gb useable, not really worth it.

Thanks guys!!!! Actually it is running Win7 Ultimate 64 bit. Unfortunately my sister in law threw out the OS disks along with a full suite of Office 2007 disks.

I don't know how much the speed effects the ram. Per the report this is PC2-5300 running at only 333 MHz. In researching I found that I could use up to PC2-6400 @ 800 MHz but probably not go to the 1066 MHz.

Crucial recommended this...
Module Size: 4GB kit (2GBx2)
Package: 200-pin SODIMM
Feature: DDR2 PC2-6400
Specs: DDR2 PC2-6400 • CL=6 • Unbuffered • NON-ECC • DDR2-800 • 1.8V • 256Meg x 64 •

As I said I don't want to throw a lot of money at something that is this old. I found some used memory (Mushkin) that has all the same specs but was Cas5 rather than Cas6. It was nearly half the price, $38 vs $72 for new.

So with that new info, would you stoill not waster your money on memory upgrade?

Nope, not worth it for the miniscule amount of additional memory you'd get.
