Whenever I add more than 4GB RAM to my Windows 7x64 PC I get a STOP blue screen with the message 7E.
I have just replaced motherboard, ram and graphics card so it is definitely not that.
- Core i5
- Gigabyte P55, DS3R
- GSkill Ripjaw 2x 4GB
- ATI 6850 Sapphire
What could it possibly be?
RAM is the only variable causing the problem and its definitely not the ram itself.
PS. I would rather not do a reinstall of Windows either. Also, I'm posting here because I think its an interesting and mysterious problem that may help others if there is a good answer.
EDIT: Thanks guys for such a thorough response! This problem has been plaguing me for months. Many times I have though I had resolved the problem only to have it happen the next computer restart.
At the moment I haven't had a blue screen after I disconnected my Microsoft Windows Media Center Blaster. I also remembered that ages ago I changed the driver for this device so that I could use it for other purposes with EventGhost. I'm hoping this was the problem all along.
I am unsure how having more than 4GB of ram caused it to occur however I think it may be something to do with 32bit/64bit compatibility regarding where hardware devices memory are mapped in the VM space.
