Your motherboard is dual channel DDR3,...you should have a matching pair or dual channel kit of ram installed,... 8G would be nice as it would have enough for the APU and OS.

Either use ASRock's recommended memory list http://www.asrock.com/mb/AMD/FM2A58M-VG3+%20R2.0/?cat=Memory
Or if you like a particular manufacturer search for your motherboard on the memory page for a compatible dual channel kit.

os- win 7 64 bit
cpu- amd a6 6400k
mem- crucial ballistix 4 gb x1
mobo- asrock a58 fm2 vg3+ r2.0

This is due to the shared memory with the iGPU on the APU. It is perfectly normal.]]> Wed, 24 Aug 2016 23:52:43 +0000 https://forum.asrock.com/forum_posts.asp?TID=3315&PID=16207&title=4-gb-available-ram-3-46-usable#16207 <![CDATA[4 gb available ram (3.46 usable) : Is this normal? i look into the...]]> https://forum.asrock.com/forum_posts.asp?TID=3315&PID=16202&title=4-gb-available-ram-3-46-usable#16202 Author: asrocka58vg3r2

Is this normal? i look into the mem support list but theres no 4gb on crucial. is my ram size not supported by the mobo? and what does the memory module mean? do i need to get the exact module that is on the list? if yes, how can i identify those modules? for additional info about the mobo http://www.asrock.com/mb/AMD/FM2A58M-VG3+%20R2.0/?cat=Memory
