You have the sticks in slots 1,3 (yellow ones)? (I don't have a manual handy), Those should be the prime slots for dual channel and it should recognize it as such. There may be a toggle in the BIOS to set dual mode but don't remember one.

Have you tried default settings? Load optimal defaults and simply see if it will boot up. The memory should be installed int he same color slots. I believe A1 + B1 or A2 + B2.

Thank you

Dual channel mode on the mobo is A1-B1 or A2-B2
Yellow Is A1-B1

whith load defaut setting in A1-B1 don't start

The bios Is same of P5Q pro or deluxe mobo i think

Send the memory in for a different set, you should have no issues with any of those boards.

i don't understand your reply ......


i tell you just the problem

can you tell me why i cannot use the dual channel ?
what i need change in the setting to work in dual channel ?

[GSKILL TECH]

Return that set for a new set. Or post pictures of your BIOS so i can see if you are missing anything. Otherwise with the settings you have changed, or default, the computer should be able to at least boot up.
