Do you have 8 slots on your motherboard and are the sticks in the right dimm slots? Is windows just recognizing it wrong in settings, did you check somewhere else to see if it detects 32gb like the bios?

Yes bios reads all 32gb and no only 4 slots

It could just be a windows task manager issue. Check in system information https://www.computerhope.com/issues/ch000149.htm

Silly thing, but one thing to check none the less, have you re-seated the RAM? Some people have found some of their RAM was unusable and they found out that the RAM wasn't quite seated all the way.

I have a blog! And a list of guides I've posted

All of it is detected, only 16 says it's allocated to windows

Just pointing out that reseating the ram won't do anything :) 

Yes it may, based on two reasons:

  • At least one person re-seated their RAM and it solved their problem, which is the same problem being experienced in this thread (https://www.tenforums.com/performance-maintenance/23381-unable-use-all-ram-installed-2.html#post402891)
  • The pinouts for DDR4 SDRAM have some important pins on the edge that if not actually making good contact, may not allow the RAM module to completely work. Since the system is still able to detect what kind of memory is installed, my guess is the SPD pins are connected. Looking at the pinout, that means on the other side one or two of the data lines may not be connected.

Either way, re-seating RAM is to ensure that it's actually installed properly. This isn't because I think it's installed properly and re-seating it will fix it, because until OP confirmed they did it (and made sure it's properly installed), I can't assume it was installed properly.

 

It's always important to make sure the hardware is in the correct configuration (plugged in, switched on, etc.) anyway regardless of whether or not you think it is. I've had too many times working with setting up equipment where the plug wasn't actually in or some switch wasn't actually flipped.

I already tested each ram stick so I moved them around . In the bios it shows all my ram . Cpu z does too but only about half sometimes more is usable in windows

Then I'm also going to assume you have the BIOS up to date.

 

See if opening up msconfig -> Boot tab - Advanced Options button and setting the maximum memory to 32768 does anything. If it doesn't then you likely have a defective motherboard, defective RAM, or in rare cases, a CPU pin got hosed. Either way, this points more towards it being a hardware issue.

Maybe but I got a tip on switching some settings in the bios so it uses the pcie slot . Something to do with using the gpu and memory being saved for the display

Integrated graphics wouldn't by default eat up 16GB of RAM. I don't even think mine lets me go past 1GB.

Looks like one of my water blocks cpu screw had broke . Replaced it and reinserted my cpu and it shows 32 gb of ram. So guess the cpu wasnt making full contact with the board
