HP DL380 G7 does not accept additional ram memory. What is correct ram upgrade configuration?

Hello,
need to upgrade sever memory. Currently, by factory installation, server contains 12GB (2gb x 6). Server contains 2xcpu, and 18 memory slots. Each cpu has dedicated 9 slots, or 3x3 memory channels.
I have bought 2x 4GB, and was installed into each 1 channel empty slot. But server/bios is refusing this kind configuration!
I'm confused, as currently not sure what is proper way to upgrade memory.

Powerpoint schema attached.

Thank you in advance for help.

Hi There,

Do these HP memory population guides help at all?

All of the provided examples, seem to have the slots identically populated in each Channel. i.e. if there is a DIMM in CH 1 Slot 2 there is also one in CH 2 slot 2 and CH 3 slot 2.
Although there is this comment in the article :
It is not required, but it is recommended to load the channels similarly if possible
which slightly confuses me as it would suggest what you have done is an accepted configuration..

Regards

Guy

Are you sure you got the correct type of RAM for your server? Your new RAM should be of the same type as the original RAM.

Yes. The model, and type is correct. But, I'm afraid I will need to spend more money for additional sticks, to met with hardware compliance. Currently I have bought only 2x4gb 1333mhz, and current in server are 6x2gb >> then I guess I will have to buy 4x4gb, which will mixed with 6x2gb. And in the end each channel will contain 2gb+4gb.
