My motherboard is Gigabyte F2A78M-HD2 with two RAM slots.
My problem start after my power supply stop working I take my PC to service after a week my PC was ready to be use with installed new Windows 11 Pro 64 bit .
but when I get home and power up my PC my RAM was only 8GB before to take my PC to service was 16 GB two RAM sticks 2 x 8 GB 1600MHz . I go to the bios to check why my PC is use only one RAM stick. The values on one of the RAM sticks was with very low values compare to working RAM stick (both RAM sticks are same model) is like PC is not recognize it. I ring to the service to ask them about my problem they explain to me - is possible one of the RAM stick to have a faulty. Later same day I found new RAM sticks 2 x 16 GB 1600MHz in internet. Before to make my purchase on my new RAM sticks I check the manufacturer on my motherboard Gigabyte, can my motherboard support 32 GB RAM the information was - can support up to 32 GB. After I saw this info I make my purchase. After almost two weeks my new RAM sticks arrive to my address. I change both of RAM sticks before to power up my PC I check if RAM sticks are connect properly I didn't find any issue. I Power up my PC check my RAM and it is 16 GB not 32 GB. I already check in Bios and both RAM sticks is visible with same values. Before to change my power supply with new one and my previous Windows 11 Enterprise in Task Manager ->Performance->Memory where is Slots used was 2 of 2 now on Windows11 Pro in Task Manager ->Performance->Memory where is Slots used is 1of 4 Slot 1 - empty
Slot 2 - 4.0 PB, 1600MHz , Slot 3 - empty, Slot 4 - empty
Can my problem be from Windows 11 Version?
