Cant Enable PAE mode

i've tried what Microsoft suggests. i've Tried EasyBCD but still it snot enabled, and i still show 3.5GB of 4GB usable. (where thers 512MB Hardware reserved) Any idea how to force this to work?

I'm afraid 32 bit windows 7 has a 3.5GB RAM limit no matter what. The limits then vary working your way up the 64 bit version ladder. (the unofficial PAE stuff for Windows 7 is unstable)

Actually, scratch that. Apparently the limit is 4GB for all 32 bit versions but starter :/

Apologies for my confusion :/
You may find this handy, as it sound like the same issue: The usable memory may be less than the installed memory on Windows 7-based computers

Guess so, sorry :/
Upgrading to 64 bit may fix it, but that costs money and you'd need to do a completely fresh install :/

All 4 GB should be available if you install 64 bit as according to the specs for your motherboard (assuming the one in your specs),

ECS Web Site

it supports up to 16 GB total (2x8 GB). Also as far as the memory remapping, if I'm reading the manual for it this is the setting (worded differently than what would be expected),

and is enabled by default.

PAE is enabled by default (DEP), but Microsoft has crippled it, so it cannot help you.

It would not help in this situation either way. The hardware will still take the 512 MB of address space. Windows does not control how the address space is allocated, that is left to the hardware. Its out of its hands.

I haven't checked the specs, but according to stormy13 the hardware supports > 4GB plus memory remapping, so a non-crippled PAE kernel can use all of it.
