Windows 7 64 bit only using 3.24/4GB RAM.

Thatguy2007 · 16 Sep 2009

I installed Windows 7 professional 64 bit RTM on:
Dell Inspiron E1405 with 4 GB RAM
i have the latest drivers and BIOS that came out. I know that 200MB went to help the chip-set shared video memory. But wheres the rest? i need know whats going on??

Thank you,

P.S. should i just downgrade to a 32bit, since almost everything runs on 32 bit, and i'm not really benefiting from 64 bit??

Check in your BIOS for a feature called memory mapping, or something to that effect. Some people with this issue have resolved it by enabling that option, if it exists.

I have a Mobile Intel 945GM express chipset family, i will check to see if i can do that, but i doubt it, thanks tho.

The system may also be using more memory for video than you think, depdning on how that is configured as well.

Thatguy2007 · 16 Sep 2009

i checked the BIOS it is only using 256 of video memory:

Do you think i should just down grade to a 32 bit, since I'm not using 100% of the RAM? ( plus almost everything runs on 32 bit)

Thank you.

Why downgrade to 32bit? Just keep 64bit so if you ever increase your installed RAM you won't have a problem. Plus, there's not a lot of programs out there any more that you can't get running on a 64bit OS!

True but my laptop can only handle a max of 4 GB RAM (200-pin SODIMM, DDR2 PC2-5300 • CL=5 • Unbuffered • NON-ECC • DDR2-667 • 1.8V • 256Meg x 64 { i didn't find more RAM that has these exact specs}) .but yea w.e. its all good.

Thanks guys.

Im writing this on a 1405 4gigs 32bit. 32 has a bunch of benifts. easier to find drivers, run cooler, takes lees HD space, uses less resources.

One way to find out is to backup first install 32 if there is enough space dual boot. then pick the one you prefer and delete the other

Hope this helps
