GA-Z68X-UD4-B3 Dual Channel problem

[Jakk89]

I just built a new computer with a GA-Z68X-UD4-B3 motherboard but it refuses to boot up when the ram is in the recommended slots(1 and 2) for dual channel. It is running fine in single channel but i'm at a loss as to why that would be the case. The ram is the exact same(g.skill 8gb sniper 1.25v ddr1600) but in dual channel mode the computer will try to start up but shut down after a second or so and keep trying to boot up.

Does anyone have any idea why this is happening and how i can solve it? Both the board and ram support dual channel but the only way it'll boot up is when the ram is in 1 and 3(same channel).

1 and 3 (2 and 4) IS DUAL Channel.

Actually it's not. It depends on your board, and on mine, it is set up as [1, 3] [2, 4]. To double check i even used CPU-Z and it is running in single channel. It's never good to assume that all boards are the same.

Hello Jakk89,    Welcome in the forum,

I have a suggestion for you about your situation.


Make a clear CMOS.

My favorite method is:

disconnect the power cord,
purge the power button in front case,
remove batterie,
Change a positon of the jumper on the motherboard for clear cmos. (Check your manual if necessary).
Make a contact with a paper clip between the batterie connectors fiew 5 sec,
Rechange a normal position of the jumper on the mobo.
Place a batterie
Plug de power cord
Reboot.

If you have a similar method, use it at our convenience.


Reboot,
Go to Bios, choose Load Fail Safe Default.  MODERATOR EDIT: Not failsafe default use Optimised BIOS Defaults
F10 to save
Reboot.
Check a Result.

Now make this instructions:

If you are sure about your two sticks of Ram. Just try put Ram in the slot farthest from the cpu. In Dual channel mode.

Because is the best for the ram and cpu (and for your heatsink).

Otherwise....

Just try one by one. In each slot (Bank Ram). And Reboot.
This is very basic like action. But you have a possibility for verify each slot.
