Hi All,

I've get a Gigabyte motherboard and I'm using it with an Intel Core i7 4820K CPU and 32GB of RAM but the weird problem is that the BIOS can see the whole amount of rams but the windows can see only 24GB of RAM. I've tried to put another 8gigs of modul on it and after that the bios could see 40GB of RAM but the windows only 32GB. Do you know what would be the problem?

Have you tried two memory combination? Is the Windows see the memory correctly?

DDR3_1 and DDR3_2

DDR3_1 and DDR3_3

DDR3_1 and DDR3_4

DDR3_2 and DDR3_4

DDR3_3 and DDR3_4

It looks like you are using windows 10 but that shouldn't really matter. Windows is using the memory some where. Or try  going into msconfig. Right click on the start button / click run / type in msconfig and click on it. Then click on boot then click advance and see what it says in there. All the boxes you shouldn't have any check marks in them.

Try..

Open "System Configuration". (Windows + R), type in "msconfig" and press OK.
Under "Boot" Tab click on "Advanced Options" and check "Maximum Memory" and select 32768.
Press OK and Apply.
Reboot.

Additionally, if you have tried to OC using easy tune, or manually in BIOS, or set up BIOS profiles, please delete existing profiles and reset your BIOS to default.  Then set up from scratch.  See if that helps.
