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

24 Oct 2009   #11

Win 7 Ult SP1/Win 10 Pro (all x64)

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.

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.

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

Linux CENTOS 7 / various Windows OS'es and servers

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.

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.
It depends on your mother board and maybe BIOS.

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

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

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.
