My notebook is an HP dv6757ca which has the following specs:

  • Windows Vista Home Premium 32-bit (currently using Windows 8 Developer Preview 32-bit)
  • Intel Centrino Duo @ 1.6 GHz
  • 2 GB RAM

I am planning to upgrade from 2GB to 3GB and using Crucial's Memory Tool I was able to determine that the following memory was compatible with my machine:

DDR2 PC2-6400, DDR2 PC2-5300, DDR2 (non-ECC)

I found this with a bit of searching and I was wondering if it would be compatible with my machine. From what I can tell, it looks like it will be... but I noticed that the memory tool mentions "PC2" whereas the product specification page mentions "PC".

Edit: I found the data sheet for my chipset (an Intel PM965 Express Chipset) and it lists the following features:

chpset datasheet

Will any of these features cause trouble or indicate a possible incompatibility?


There's really no such thing thing as "PC-5300", so that's a misprint.

The "2" in PC2 means DDR2, which the linked RAM is.

Based on the info you've provided, I can't see any reason that won't work. :)

  • Is there a tool to determine whether this memory module will work with my existing module? I have 2x 1GB sticks in there now and I would be swapping one of them out for the new 2GB stick. – Nathan Osman Dec 26 '11 at 20:06
  • I know of no such tool, but there shouldn't be any trouble mixing them, as long as you stay less than 4GB total as that notebook only supports up to 4GB. – Ƭᴇcʜιᴇ007 Dec 26 '11 at 20:08
