Linux does use all available RAM, not only regarding Physical Address
Extension (PAE). 1. Windows might not have provided Physical Address
Extension (PAE). 2. Even if Windows should have had access to all
available RAM, it not necessarily does use all available RAM to cache
or as tmpfs or ... as Linux does.

Apart from this, it might have been a BIOS issue and maybe the RAM
wasn't bad. Memtest is _not_ reliable. Using Memtest makes sense, but
you shouldn't trust it.

If RAM shouldn't pass Memtest you need to rule out other issues, at
least you should replug the RAM bars.
