M77: BIOS settings to enable 8GB memory in Windows

Hello
Good day
sorry for my bad english
i have lenovo thinkcentre m77
serial number: xxxxxxx
but its damaged unfortunately
so i take the motherboard a88 and put it in another case with

OS: Windows 7 Ultimate SP1 64bit
CPU: AMD Phenom II x6 1055T
Ram1: KingStone DDR3 1333 4GB
Ram2: KingStone DDR3 1333 4GB
GPU: Gigabyte GTX 1050 TI
PSU: Evga 650w Bronz

the motherboard work very fine but the only problem i have is the ram count
in bios setting it's read all 8GB of ram but in windows read only 4GB and other 4GB is usable please find below files
also i changed the ram places and also update the bios from 9VKT29AUS to 9VKT33A but i have no option to change anything in bios settings exception few option like video memory and some power otion and boot sequance
how i can fix this problem and mybe i add another 8 gb in future
also i need the manual to connect my front panel light ( power led, HDD led, Speaker)
all i need to skip this problem is change the bios system to have more control or option with ram and cpu

Re: about m77 bios

I suspect that one of your memory DIMMs is not compatible or faulty.  Did you run MemTest86 as suggested in the link above?  If so, what was the result?  It would be helpful to know/look up the Kingston part numbers from the stickers on the DIMMs, especially if they are not the same.

Re: about m77 bios

Is it this part number:  KCP313NS8/4 ?   If yes, then I recommend that you call Kingston directly, as this particular memory (this one only, as you can see below, there is one option for memory from Kingston) is guaranteed to be 100% compatible.
