help with ram issue

[theoldman]

so here is what i got i have asus m4a89gtd-pro usb3 mother board yes i no its old but it dose what i want . when I built this unite i had 8gb of ram so recently i decided to up the ram to 16gb ,yes the board supports it , when i put the new ram in windows,cpuz and speccy sees it all but when i go in to bios it only sees half . tried clearing the cmos both by battery and the jumper but still the same. So i decided to put the old ram back in and even that is now showing in the bios as only half. the bios are as updated as it can go . Was thinking of just reflashing the bios to see what it would do . And yes i have reseated the ram and tried each stick one by one and they will show as supposed to . I just dont understand why the other programs see the ram but windows says that the 4gb are in reserve and bios dont see it at all . Any help would be appreciated     thanks

One of the Ram slots on the motherboard is bad or the memory controller in the cpu is bad. One or the other.

The only way to test this theory is by trying a different cpu or mainboard.

sorry so long to reply but you where right some how the cpu got a few pins bent so i upgraded the cpu till i can look at the old one closer . but now i have a different problem after i replaced the cpu and i up graded the ram when i start windows it hangs on the loading screen ,i looked it up and every one show a fix but the talk about when you get the windows logo with the spinning dots. What mine is doing is you get the logo but no dots so i restart the pc and it loads as normal . this is windows 10 pro . I didnt have this till i did the upgrade  should i do the fix that they all say or try something different??  any ideas ????   and thanks again
