Windows 7 Ultimate 64-bit doesn't support 4GB RAM?

[simonsiknasty]

Hey guys and girls,
I have had Win7 Ultimate 64-bit RTM installed for a couple of months now, but there is one issue that I have not been able to solve for this whole time.
When I first went to install Windows 7, I had to remove a 2GB stick of RAM in order for the installer to even start without blue screen-ing on me.
So I took the RAM out and managed to get 7 installed (yay!). However, when I tried to reinsert the RAM, I got the same BSOD that I would when trying to install 7 with the other 2GB in. I gave up after a couple of tries, and it has taken me this long to try to solve the issue.
I am pretty sure that my specs are 7 Ultimate x64 compatible? Because if not, that is most probably the source of the error.
Otherwise, could anyone lend a hand? It really hurts having 2GB of RAM lying around in a drawer being useless.
Thanks everyone in advance.

Added:
By the way, install was a clean install from XP SP3 32-bit. Formatted all my HDD's.

This is a very common problem with Windows 7.

It's probably a BIOS issue. Or perhaps there's a Windows update for it. Try searching the forums as I'm sure this has been discussed many many times.

Do you think that the final version may not have this issue?

 

[sup3rsprt]

RTM is the final version. So yes, it has the same issue.

I've been searching and all I can seem to find is people saying that Win7 doesn't recognise the RAM. Whereas in my case, the computer will BSOD before I even get to startup.
I'll sleep on it for tonight (night where I am at least) and see what I can find tomorrow.
I'm all ears for anyone who could find a link to a thread that is similar to my issue, or try to resolve this specifically.
Apologies for my ignorance.

i am running win7 64 bit with 8gb of ramm
no problems here...

to check of you can run 64 bit
go to the system
then to the wei page...
under the score you can push for more details.....
and see iff you can run 64 bit

 

[sup3rsprt]

to check of you can run 64 bit

It should be clear that since the system is running 64-bit Windows, it can run 64-bit Windows..

This almost sounds like a bad RAM socket on the mobo rather than bad RAM...

Except that many people say the problem only occurs with Windows 7 and not other OS like XP or Linux.

I have 6gb of RAM. It is still a common problem for Window 7 not to install, when there is an excess of 2gb?

I ask because, if I try to install 7 (will received DVD on Tuesday) and I have a problem memory, I would prefer not to even begin the clean install process. I would not know how to remove the RAM.

I have 12gb of RAM and had no problems installing Win 7 Ultimate x64 twice on two separate partitions.

I think maybe bad RAM, dirty sockets or BIOS settings are to blame, as all 12gb are recognized on mine.

 

[sup3rsprt]

Well he can easily rule out bad RAM and/or motherboard if he can boot into XP64 or a x64 Linux distro with all of the RAM installed.

 

[Ex_Brit]

Try looking in MSCONFIG (Start/Run msconfig) Boot tab/Advanced button to see if the memory is limited there.

Hi there
I've also also no probs with 4, 8 or 16GB RAM.

Note however the following

1) Installation may APPEAR to hang - can take 15 mins or so with no apparent activity before you get License / Language / options screeen (upgrade / clean install)

2) Sometimes having external USB devices plugged in during install causes hangs -- (mouse / keyboard OK but remove USB sticks, usb disks, usb tv cards etc). Plug these back in again after install.

Cheers

It depends on your mother board and maybe BIOS.

Your Dell should be OK, both of mine (4GB RAM each) installed with no issues.

 

[mcleod55]

Have you updated your motherboard BIOS. That might help. I installed yesterday with 4 GB ram with no problems at all.

 

[jltk87]

having the same problem as you guys. cannot install more than 2gb ram. just updated the bios and nothings changed. If i leave it to boot with 4gb then it hangs on the windows logo and after a while just turns itself off.

asus pn532 sli-se-deluxe, 2.4ghz dual core, corsair ram, 64 bit pro.

Guys

Just passing thru but did anyone suggest checking max memory setting in BIOS?

I don't think anyone has mentioned it Ken. I remember you mentioning to someone else, but he couldn't find that setting. I don't know if he ever figured out the problem either.
