Just Built, Small Problems (Well Bigish)

Here in a nut shell are my two main issues with my new build. I have an Average knowledge of Hardware etc.

-Restarts from BIOS cause my Computer to be hung up on the VGA part of Boot sequence (at least what it shows in Q-LED's)
-With 8gb of DDR3 installed (4x2GB) only 3.24 GB is acting as Usable and 4.8GB in Hardware.

Here are my specs:

CPU: I7 860 2.8GHZ @ 2.8GHZ
Mobo: Asus Maximus Formula III
BIOS: 901 (Just flashed for latest update)
GPU: XFX 5870 @ Stock
RAM: (4X2GB) Patriot Sector 5 1333mhz @ 1066MHZ (Having trouble getting it to 1333mhz at Stock Timings)PS
PSU: Corsair HX850W Modular
OS: Windows 7 Ultimate - X64 - 64-bit

Couple other small cards like Sound card etc but nothing that should be causing these issues.

Main issue is the RAM, I don't reboot from BIOS that often so it isn't a big deal though I would like to fix it.

I have read up on the RAM issue and it appears to be a thing to do With Windows 7 or something, and it said to make sure that Memory Remap is turned off in BIOS which I managed to find in Advanced-Chipset. When I disabled this it remapped even more of my Memory, before I had 4GB usable now I have 3.24Gb which I think is the magic number 32Bit use.

Here is a picture.

The back of my machine has a clear CMOS but I would like to know what I'm really doing, before I go pressing buttons.

-Cleared CMOS, thus reseting the Memory Remapping feature which specifies below it to allocate 3.368gb-4gb of memory to PCI hardware.

It is still stealing 4gb but better then having it on where it steals 4.87GB which is far too much. I would like to at least see 6 gigs of my system I can fill up 4GB on occasion.

-bump , Would love to have full usage of my 8gb.

The sticks are running on Single channel due to 4x on 4DIMM's but not sure if this is a factor.

Found another tip to lower the Page file usage from 4gb to 1Gb now, but it still is eating up 4gb of my memory.

contact asus sounds like some kind of bios/memory issue.

have you tried 2 or 3 sticks? are you overclocking the memory?

Just tried 2 and 3 sticks and went and looked on Asus.

1 Stick: 2Gb Installed and all 2GB was usable
2 Sticks: 4Gb Installed and only 2Gb was usable
3 Sticks: 6Gb installed and only 4Gb was Usable
4Sticks: 8Gb installed and only 4Gb was usable

Went on Asus and it explained something about how the Motherboard reserved memory for its various parts and PCI-Express cards etc, but that doesn't explain why it sucks less memory when I have 1-3 Sticks installed and more then I have 4 sticks installed.. Then I read an article about older chipsets the 915G being limited to 4GB of usable Memory but still doesn't link up.

Alright so far so good, I noticed DIMM_B1 was a bit loose and had problems clicking in so I swapped it with DIMM_B2 and It looks good all 8Gb are showing up now as usable. =D
