Problem asus rampage ii extreme no detect 6gbs and tri channel

[rrecarte66]

Hi im from Peru, i just bought a Tri channel memory kit F3-12800CL7T-6GBPI and have an ASUS RAMPAGE II EXTREME with Core i7 920, my problem is that my motherboard only detects 4GBS in the BIOS and in the SO that is Windows 7 Professional 64x,but when I use CPU ID 64bits in memory it appears 6000MB but in channel appear DUAL, I just tried changing voltages or many other things but i cant find any solution, I would really appreciate that give me a solution. Thanks

PD: i also update my bios to version 1802 and removed and put back the processor and nothing =(

how ? it necesary to reconized the 6gbs?is not only installing the 3 DIMMS? please give more info i overclock several times but i dont know if the parameters were right, i used the guide to overclock "F3-16000CL9T-6GBTD + ASUS Rampage II Extreme BIOS Settings" that you posted but i thing for my memories is different!!

thanks in advance

thanks to answer quickly, i have a question , the latency of my memories is 7 do i need to put these value where it says 9 ?

for example here

DRAM CAS# Latency - 9
DRAM RAS# to CAS# Delay - 9
DRAM RAS# PRE Time - 9
DRAM RAS# ACT Time - 27



in the back of my memories package says these

F3-12800CL7T- 6GBPI

DDR3-1600 PC3-12800

2048MB * 3

CL7-8-7-24 1.5V


Thanks!! =)

Yes, sorry,

DRAM CAS# Latency - 7
DRAM RAS# to CAS# Delay - 8
DRAM RAS# PRE Time - 7
DRAM RAS# ACT Time - 24
