Does bios or other OS see the full 32gb?

gentoorockerfr,

Some systems only support 16GB. You can fit more but the system does not know how to use it, so its not seen.

Other systems can use more memory but they are fussy amount the DRAM geometry. Double sided RAM sticks may work but not single sided ones.

What motherboard do you have?
What is the make and part number of the RAM?
