Okay, I was thinking the problem was not hardware but software. Do you think there is a problem with the Mother card ?

It continues to say "single channel" for each configuration. But the sticks are correctly installed x)

problem with cpu or mainboard then i feel

1 stick should go into slot a2 (says single channel) 4gb
2 sticks should go into a2/b2 (says dual channel) 8gb
4 sticks into a1/a2/b1/b2 (says dual channel) 16gb

Yes.
If I put one stick (so 4GB) I can use 4 GO. There is not RAM reserved. Let's try to reset the bios !

so ?
all 4 stick show 4gb when inserted by themselves into slot a2 ?
and all 4 sticks also show 4gb when inserted by themselves into slot a1/b1/b2 ?

so you have proved each stick works properly in each slot on its own ?

if so i would be inclined to presume a fault with either the cpu or the board

have you also reset the bios to defaults ?

I just tried with two of 4 GB (so 8GB) and only 4 GB are usable. So it's either Windows or the BIOS that limits]]> Mon, 03 Sep 2018 20:55:44 +0000 https://forum.asrock.com/forum_posts.asp?TID=9600&PID=55709&title=only-half-of-ram-is-used-on-ab350-pro4#55709 <![CDATA[Only half of RAM is used on AB350 Pro4 : Done!

Done! I think the problem is not hardware but software. All components seem to work properly]]> Mon, 03 Sep 2018 20:50:07 +0000 https://forum.asrock.com/forum_posts.asp?TID=9600&PID=55708&title=only-half-of-ram-is-used-on-ab350-pro4#55708
