Windows 7: Only 763MB of 3GB Ram Available - WTF?

Only 763MB of 3GB Ram Available - WTF?

Hey Everyone,

I'm running Windows 7 Ultimate on an eMachines E642. I bought the laptop with 1GB built in and had them add an additional 2GB. Unfortunately, right now the system only reports seeing 763 MBs. It's ridiculous - I can't even run 5 tabs in my browser without taking up 90% of my ram. Screenshots of the System screen and Task Manager attached.

Anyway, I'm aware of the "only seeing 3GB out of 4GB" problem people experience with x64:

x64 Win7 is reporting only 3GB out of 4GB RAM

After reading through a few threads, I'm pretty sure that's not the issue. I'm only seeing 760MBs out of 3GBs, I don't think that's my graphics card / OS taking up the RAM.

One solution I wish I could try is the memory remapping. There is no "Chipset" option in my BIOS and I don't see memory remapping anywhere. And yes, I've updated to the latest BIOS.

Any suggestions?

Thanks guys =)

- Derek

Here are the CPU-Z screenshots, as well as the Resource Manager's memory screen.

I think the answer would be your hardware is useing it up

if you look in the grey area you have there it is reserved meaning when it is needed for something demanding it will be enabled


Also filling out the specs on the bottom would help are you running x64 /x32 ?

also wondering if your board settings need to be calibrated ?

these are things that could be screwing you up

Heya,

I don't think it's #1, because Windows gets REALLY slow when it hits 700 MBs. It doesn't reallocate any more memory, it just caps out.

I'm running x32.

How do I calibrate my board settings? As far as I can tell, there's no RAM options in BIOS ...

I noticed you are running a E -machines there's really no way to get around it prebuilt factory setup maybe you should call the distributer or consult your pc guide that came with it

Hi Derek
Go into your BIOS do not do anything while you are there, then select save and quit to come out again.
This is the wierdest answer I have heard but it also seems to work for others
I hope this helps

Please post back if it actually makes a difference or indeed if not lol

Check your manual on how memory modules are installed and assigned. Many motherboards (BIOS) will assign different types/sizes of modules as separate memory areas. Depending on how it's installed can also cause access to revert to single channel rather than dual channel--In essence, slowing down your PC. It appears your 2Gb module has been assigned to hardware and thus can't be used by Windows to allocate memory to software.

I would replace the 1Gb module with another 2Gb module and make sure they (2x2Gb) are installed in dual channel mode. I'm not familiar with the eMachines so I can't say which slots on your board are which channels. You'll need to check your manual. The alternative would be to replace the 2Gb module with another 1Gb module. In any case, use the same type and size of modules so the BIOS will assign it as contiguous memory.

Pooch: No effect =/

carwiz: Man =( Another $40 on RAM ... I was really hoping to just pay for a complete, working 3GB package and not have to install anything. Not in the same city I bought the laptop in so I can't take it back to the store. Aight .. I'll see if I can find a store that'll switch out the 1GB for a 2GB of the same type/size. (I've never opened a laptop before ... Don't think I want to do it myself.)

Thanks guys =)

If anyone else has any suggestions before I take it into the store, I'm all ears.

Thanks!

It is a good thing you are taking it back to the store

They will have no choice but to fix that issue and don't take thiere excuses for a answer

Also keep in mind opening up the Laptop yourself will result in voiding the warrenty which wouldn't be very smart for the reasons you want to make then either fix the memory issue or issue you something that works better because of it being faulty or what ever issue

I wish you alot of luck and hope-fully they will do the right thing and fix your issue without charging you to do so ....

There isn't anything you can do about mmio mapping. MMIO devices take RAM before the OS loads; Windows gets what's left over.

This is a really odd one though...
