Windows 7: 6 GB RAM installed 1.74 GB Usable

Win 7 Ultimate x64

Both the bios and Windows are seeing the full 6 GB, but for whatever reason the bios is keeping the 4 GB back as hardware reserved. Had a look at the various manuals for your laptop but there wasn't a whole lot of info regarding what bios settings are available. If it is there, have you tried "load failsafe deafults" (or however it may be worded in yours)? Seeing as it won't boot with just the 4 GB stick in, would have to try this with both it and the 2 GB installed.

That it won't boot at all with just the 4 GB stick in would lead me to believe that it is possibly a bad stick, or that it is just incompatible with the computer in general.

Well, time to return this to wence it came (the RAM, that is)

I guess I could always spring for a new motherboard in the future.

Still annoys the heck out of me that it saw it, but couldn't use it.
