My HP Dual Core Laptop can accept 8GB RAM (presently 4GB with 2 GB per slot) How much of the 8GB would actually be used if I fit it? Thank you

Depends on a number of factors. What is your operating system, are you into gaming, do you have many software applications working in the background etc etc.

Increased RAM can be very helpful, but it can also be overkill if there is no real need for it.

Most of my machines have 1GB/2GB max, which I find is more than adequate for my non-gaming but average needs.

3.25 for a 32bit system and all 8 for a 64bit system.

Thanks, Stupidly didnt mention its Win 7 64 bit, only reason (well important to me)is to make my Nikon Capture NX2 Imaging software a bit faster. Really needs all it can get especially as mainly for RAW files. As I understand it if, say 4GB is present only about 3 is actually available to end user? Just wondered about if 8 is in situ.

With 64 bit then all of your 4Gb should be available unless any is taken up for graphics. It is only with 23 bit that the max is about 3.25 Gb.

I suspect that increase of RAM will not make much difference as you only have a Pentium Dual Core T4300. But may be wrong others who process raw may be better to advise.
