RAM not recognized in BIOS and WIN 7 64-bit

[kLa_89]

Just installed this memory

G.SKILL F3-12800CL6T-6GBPI (2Gx3)

In BIOS and in windows there is only 4 GB RAM detected.

Spoiler

But CPU-Z is detecting 6GB of memory...

Spoiler

RAM is seated properly as described in MOBO specification, CPU is also seated properly, I double cheked...

Memtest showed no errors.

System specs :

mobo : ASUS P6T SE
cpu : socket 1366 , i7 920 @ 2,67 GHz
power supply : Chieftec 650 W
2 IDE HDD + 1 SATA WD (OS HDD)
video card : GTX 260 @ stock speed

Nothing is overcloked...

Please help, because I used all my PC knowledge and do not what to do next...

your cpu supports ddr3 up to 1066. you are trying to run 1600. only thing to check would be in the bios, make sure its set to run triple channel ram, not dual channel.

I turned on X.M.P. in BIOS and memory is runing normal @ 1600MHz, except BIOS and Win dont see other 2 GB, so nothing is changed , overcloked or not...

 

[daswilhelm]

does your bios give you an option on how many channels of ram to use?

 

[kLa_89]

nope, i didnt see that option...

 

[daswilhelm]

strange, there should be, i have setup 2 of those boards, maybe a different bios version, but i thought i remember seeing that option.

 

[kLa_89]

will check again... ty

 

[kLa_89]

there is no such option in BIOS... BIOS is ver. 0908...

 

[daswilhelm]

in that case, since the ram speed doesnt match the cpu, and its not on the QVL, i would say thats most likely the wrong ram for your system. maybe try to check for a bios update, that would be all i could think of.
