Windows 7 64 Bit (2.94GB RAM Available)

i have 4gb (2x2) DDR2 memory in my machine, however its only recognising 2.94 gb of ram, how do i get rid of this and allow it access to the full 4gb of RAM.

One stick in one stick out

Vice versa.

One stick of RAM might be faulty. Eliminate by trying one at a time.

what does it say for "total"

Is this a new install? I vagulely remember when I first installed W7 I had a similar problem where not all of the ram was available. I think what fixed it for me was:

Administrative Tools -> System Configuration -> Boot tab -> Advanced Options -> make sure Maximum Memory is unticked (while you're there, make sure Number of Processors in unticked too)

[edit] to be honest, my first thought was that you only have 32 bit windows installed and have a 1GB graphics card - it's definately 64bit? (sorry if this is condescending

)

Need more info on the rest of your machine, are you using an integrated graphic chip?

4GB Installed (2.94gb useable)

both unticked. 4GB Ram installed(2.94gb useable) is what it says.

I did edit my post, but you may have missed it:

[edit] to be honest, my first thought was that you only have 32 bit windows installed and have a 1GB graphics card - it's definately 64bit? (sorry if this is condescending )

also, where exactly does it say 2.94gb usable ?

its definetly 64 Bit, and it says 2.94 gb right click computer- properties, where it says 64 bit operating system. Sapphire HD 5850 1GB is my GPU.

interesting, you might want to post your full system specs, in particular your motherboard, perhaps it needs a bios update. Also, if you open task manager, go to the performance tab, then click on the resource monitor button, you can see more detailed information in the resource monitors memory tab, might be worth having a look at.

is your BIOS right up to date, I was having the same problem but an update sorted that right out.

Yes its fully up to date

how about the memory remapping feature in the bios (if you have that option), is it enabled?

doing my sp1 and windows updates atm will check within the next hour.

Reseat your RAM, reseat your processor (don't just glaze over these, actually do it, specifically look at your processor and socket), if a bios update doesn't sort you I bet it's a bent pin.

I'll second this ... had a similar problem the other day when upgrading a box from 2GB to 4GB ... system would only see ~3GB of it despite running a 64bit OS and despite the hardware supporting 4GB according to the specs. Eventually found that this setting had to be set in the BIOS, after spending a couple of hours trying other things, and all was OK.
