Z440 memory not in quad channel


Got a new Z440 desktop, only had 16GB of memory so I got  some more which is exactly the same, howvever, the machine is NOT seeing it as quad channel memory and it's running it in single ranks.

I've checked the BIOS and can't find antyhing in there, I've completed a BIOS update in a hope that it'll sort out the memory issue, it did not. I've run CPU-Z on it and taken a solid look at it, Whilst the manufacturer is different the specs of the memory are exactly the same.

The only thing I can think of is HP have prevented people from using any memory other than  their own. Any advice would be great.

Need to see what you see in CPU-Z.

I think it's ok, I think it could be a limitation of hte motherboard.

You want it to run in independent channel mode anyway, interleaving is a thing of the past. Just wandered where you were seeing the info saying "the machine is NOT seeing it as quad channel memory and it's running it in single ranks.".

It may just mean you are confused about what "rank" means.
