Computer won't boot in dual channel

[Jakk89]

I just got a new computer and the computer just keeps restarting if i have the ram in dual channel. It runs fine in single channel. The ram is the exact same(g.skill sniper 8gb 1.25v) and i'm using a z68-ud4-b3 motherboard. Does anyone have any idea why this would be the case?

try Tight and increase VDIM 1.5

Sorry but i know very little about changing BIOS settings, could you elaborate on what tight and vdim settings do and how i would go about changing them?

Install hybrid EFIBIOS from your cd motherboard, it simple and easy to find memory setting ( read guide your book ) I can't give elaborate perfectly. You must experiment it by self and don't overvolt too high .
Gsniper very low vdim 1.25 maybe increase small.

Just sample. Gsskill 1600mhz
Stock: 1600MHz 9-9-9-24 @ 1.25v
Tight: 1600MHz 8-9-8-25 @ 1.5v

Hey, i haven't changed any of the settings in the bios because if it runs everything in single channel, shouldn't it run in just second channel also?

I swapped the ram and it seems the whole 2nd channel doesn't work. I used one piece of ram at a time and tried all 4 slots and both slots in channel 1 works but neither did in channel two. Does this mean i have a faulty channel 2?

Should i RMA the board?

You must test it first use memtes86+ and test it one by one also try in different slot, you will know slot or ram stick had error , if slot ram or ram error you can RMA
