Hi

I had the same problem, spent a couple of days on it. I upgraded the bios to latest version, that on it's own did not help. Then I moved the DIMMs to slots A1 and A2 and everything started working, and several days later it is still running fine and I see all my memory.

The manual insists the DIMMs should be in A2 and B2 but I could not get that working no matter what I tried. My best guess right now is that the manual is outdated.



In case you hit the next problem, like I did - my DIMMs are meant to run at 3200MHz, but the MOBO was only picking up 2133MHz as speed - in the end I overclocked them in BIOS up to 2800MHz and increased the voltage to 1.35V to make it all work. I have not tried pushing the speed higher, likely more can be done but frankly I cannot be bothered, this is plenty fast for what I need.

its usually (99% of the time)

one of the ram sticks is not fully inserted into the ram slot

if you have tried another kit then its safe to assume you have technically reinserted ram into slots


so i suggest
removing the cpu and try to refit that

(i tend to place a finger on cpu and press down and away from socket hinge gently while closing the lever)]]> Tue, 16 Jun 2020 22:08:29 +0000 https://forum.asrock.com/forum_posts.asp?TID=14702&PID=76496&title=ram-hardware-reserved-on-b450-pro4#76496 https://forum.asrock.com/forum_posts.asp?TID=14702&PID=76495&title=ram-hardware-reserved-on-b450-pro4#76495 Author: ThreeDee

Hi all,


i'm using Asrock B450 pro4 and R5 2600
i'm using Gskill Trident Z 2x16gb 2400MHz
its read as 32gb running on dual channel A2, B2 in bios
but when i check in task manager it say 16GB while the others 16GB of ram is labeled as "hardware reserved"
try everything from unchecked max memory from msconfig,ipdate bios, reinstall the windows,

and i can't use it at 2400MHz everytime i try to change the speed in XMP
PC wont boot (fail three times and boot but with 2133MHz)

tried another set of ram (2x8GB) and the problem still occurs
i'm sure there is no problem with the ram kit
so i'm thinking maybe i get a faulty MB, can i claim warranty for this issue?
or maybe there are some troubleshooting that i miss?

any feedback is appreciated]]> Tue, 16 Jun 2020 16:25:21 +0000 https://forum.asrock.com/forum_posts.asp?TID=14702&PID=76487&title=ram-hardware-reserved-on-b450-pro4#76487
