Dual channel won't post for asus z68.

[jamfan75]

just purchased the P8Z68-V and I am using Corsair Memory modules CMZ8GX3M2A1600C8 (which is listed as being compatible). One stick in DIMM slot A2 works fine, but trying to run both (in A2 and B2) does not work. Board will not post (red Memory LED on). Initiating the memory test runs the board through all of the memory tests, but still does not work. A1+B1 also does not work.

Running the sticks in single channel (A2+B2) does work and memtest86 passes. Do I have a bad motherboard? Could it be some other issue like a weak power supply (550w)?

thanks

Press the Mem_OK button (you may have to hold it for a few seconds - check your manual).

I have tried the mem_OK button. it runs through all of the tests with the reboots and LEB blinking until finally it just stays on.

I did misstate above that A2+B2 post in single channel. They post fine when using A1+A2. Any combination of the B slots does not work. This morning I tried one stick of ram in both B1 and B2 and neither of those post either. I think basically both B banks are dead.

Probably a motherboard problem.

I have the exact same problem with a Brand new Gigabyte Z68XP-UD3-iSSD motherboard with a i7 2600k CPU and ADATA AX3U1600GB2G9-2G Dual channel kits.

Works in singel channel but turns on for 2 seconds and then off for 2 seconds (This repeats until I switch it off manually).

It turns out I bent some of the motherboard pins on installation. It looked too bad to bend them back so I just picked up another motherboard. I don't think it is covered under warranty by Asus since it was user error on my part, but I have not tried to RMA it. I was more careful with the new board and it's working fine.

Ouch, waiting on the suppliers to give me feedback on my board...

Hope that the bend pins is not the case with me, since I took good care not to bend them

Just as I said: motherboard problem.
