Mobo only works with a single RAM module

3

Mobo: Maximus VII Ranger with i7

 

I have two RAM sticks: 8.00GB Single-Channel DDR3 @ 799MHz (9-9-9-24)

 

The mobo will work with EITHER one fine, but not two, regardless of the slots I use. It displays 55 RAM not found on the LED and cycles trying to configure forever.

 

I also have an old set of 4x 4Gb sticks that result in an FE error on the LED on the mobo.

 

Any ideas as to what is wrong please? The UEFI has an excellent range of options for RAM but clearly can’t open it with two sticks installed.

 

Is there settings I can set when booting with just one stick that will make it work with two maybe?

    Sounds like you have a faulty motherboard. You could try flash with the latest BIOS in the vague hope that might help with just one stick in it, other than that, contact the store or manufacturer to organise an RMA/replacement.

    Did you update the BIOS? Sometimes the shipping version needs critical updates for CPU or RAM support.

    I also think that you have a faulty motherboard.
