Windows 7: x64 hardware reserved memory issue

x64 hardware reserved memory issue

Hey, everyone. I bought a Lenovo Z585 laptop (AMD dual graphics variant) last year for some light gaming while on vacation. It came with 1 4GB stick to which I promptly added another. The system properties showed that only 3.42GB of the installed 8 were usable. I started with the MSCONFIG maximum memory option, updated the bios, bought a new 2x4 kit of memory, even took it from it's preinstalled Win8 x64 to 7 pro x64 thinking maybe the factory installed OS was messed up (and I wasn't a fan of 8).

Lenovo support insists I have a 32 bit OS installed (disc, case and system properties dialogue say otherwise), the RAM is bad (all 4 sticks test fine in another machines and individually in this one) and that they can't touch it since it has a different OS on it than factory. Also, in my testing, I've found that it will boot with a single stick in one of the slots but not the other, no matter which one it is.





Any ideas? I'm fresh out.

Could you please explain this? What you did where?
If it's what I think you did it should look like this.
