So yeah, I just got two 4gb ram sticks in addition to the two 4gb Kingston sticks I already have.

I've cycled through all of the sockets and tested each stick, all of the sockets and sticks work and boot up.

System information shows 16 gigs of memory, BIOS shows 16 gigs of memory, CPU-Z shows 16 gigs of memory with all the sticks recognized, and yet windows itself is only using 8.1 gigs of the 16 gigs in there.

The resource monitor has a grey bar indicating that 8 gigs is hardware reserved, which fills up half of the entire bar that represents the 16 gigs I have total.

Said two sticks of ram is GSkill F3-1600C11-4GRSL, 1.35 voltage. Original ram was Kingston ram, 2 sticks, also 1.35 volts. Both rams have CAS latencies of 11-11-11-28.

Customer support for GSkill said the ram was compatible with the model of my computer, which is Acer Aspier V3-772G-5413.

None of the pins seem to be bent and the ram is seems to be seated properly as I have reseated them multiple times.

My BIOS is locked, so I can't do the memory remapping thing nor can I mod this BIOS because it doesn't seem to have any stable mods. BIOS is Insydeh20 rev 3.7.

I've already done the msconfig-boot options-advanced-uncheck memory thing.

I checked the BCDEdit settings and it said the setting for truncatedmemory was 0x400000000, which from what I've looked up should be good for 16 gigs. But I'm not sure how to make it larger. There isn't any removemem or any other memory options there.

So yeah, I've tried almost everything. Does anyone have any suggestions?

EDIT: And I've tried using cmd to do the 8.1 version of refreshing the windows experience index, which helped in win7 apparently, and I've done the windows memory diagnostic thing which said there was nothing wrong with my memory.

EDIT2: Also, task manager also recognizes all 16 gigs. I also tried removing just one stick, and my computer still sits at 8gb and now since it's 12 gb total it has 4gb as "Hardware Reserved.

What the heck is going on?

Thanks, but none of the configurations fail to boot up, and my new ram is definitely supported as just having the new ram in my computer boots up perfectly fine, and GSkill support says that my computer supports their ram. All of the slots work and boot up properly too when I mix and match.
