Yes so even though the memory is same, if you didn't buy them all together then there is no guarantee they will work together. Which seems to be the problem here. I would recommend selling these and buying ram all as one package.
this problem has been solved i just bought new mainboard thx

Click on start.
In the search bar type : MSCONFIG
Hit enter

Now navigate the following path: Click boot tab> advanced option tab, here check if the max memory option is enabled. If it is uncheck it and then hit OK button then re boot system and see if it changes anything.

Take one module out at a time and replace it, so that each time you boot and enter bios it's 12GB installed. Do this until the bios shows only 4GB Total memory on the Main bios page. If that doesn't actually change anything, you should take all the module out and test each memory slot individually to see if the system boots. If you find a slot that doesn't work, change the module to a different one and try that slot again.

I did cross test and i tested all each ram by ram but all slots are work and all ram sticks are worked
