Hi I have an
Mobo Asus p7p55d-e pro http://www.newegg.com/Product/Product.aspx?Item=N82E16813131621
This ram
G.Skill ripjaw series 4gb http://www.newegg.com/Product/Product.aspx?Item=N82E16820231277


Here are some screen shots
Resource monitor



Task manager



Cpu-z



Windows



Looks like the resource monitor says its reserving 4 gb for hardware, (the gray portion)


This is a recent problem, they are all seated correctly and no post errors.

Bios does only recognize 4gb as well

Using X.M.P for these sticks due to 16000 mhz frequency.

Any ideas how to fix this.

I had a similar problem in one of my Machines, turns out one of the Memory sticks had vastly different timings (as the same frequency) then the other ram sticks did, The ram worked, was recognized by memtest and such, but windows would always say 4gb memory reserved while that particular ram stick was installed, removed the culprit stick no problem
