So here is my problem.
I bought this pc from a friend and when he was running win7 he had no problems.

I have a Asus p6t with 3x KHX1600C9D3/4G and 3x Adata DDR3 1600G PC3-12800H.
These total are 9GB (3x2GB+3x1GB)

I formated this pc with win10, and I noticed(after 2 months) that I have only 6GB ram(both windows and bios report that)

I run memtest from a boot Cd and it recognizes all modules, with no problem
I run cpuz and recognizes all modules.

But bios report 6GB ram. The craziest of all, is that, when I remove the 3x1GB modules,
bios reports 4GB rams not 6!!!!!


Here is a memtest print screen http://postimg.org/image/45hdh6s6f/

I remember that when I formated the PC i reseted the defaults on bios.
What should I do?

I had no problem with win 7. I bought the pc from a friend and then I installed win10, reseted the bios(because I wanted to be sure that my friend hadn't done any weird changes) and now I only see 6 GB
