On a Proliant ML350, with one Xeon processor. I added x2 4GB sticks to go from 4GB to 8. I have two other 4gb sticks, and in the processor RAM bank I tried 12GB by adding three into the white slots. Didn't work. What did work, was adding just two sticks in the active processors white banks and two 4gb sticks into the same white banks for the socket without the processor. My question is: having two sticks in a bank w/o a processor, will it harm the sticks or will they just not be active? Should I try moving them into the black banks that have the processor? I just don't get why the top third stick on the white bank didn't recognize 12GB. As it is now, it recognizes 8GB, but I worry having two sticks in a bank w/o a processor. Took a long time for the server to shutdown to do this, and employees needed e-mail access, so I did not get a chance to try multiple configs. Would really appreciate any advice on this. Thank you.

If it has three white banks per processor it is at least a G6. Check the underside of the lid for the letter assignments on the memory slots, and fill them in alphabetical order. Generally these go as follows:

C-F-I-B-E-H-A-D-G [Processor][Processor] G-D-A-H-E-B-I-F-C

If there is no processor, the memory on that side will not be used.

I would check if you haven't already that the memory is the same type. The server accepts registered or unbuffered, but they can't mix. You can tell them apart by looking at the speed. It will read PC3-xxxxxR for registered and PC3-xxxxxU for unbuffered.

It also helps to populate the slots with quad rank DIMMs before dual rank DIMMs before single ranks. That's also on the label, it will read 4Rx[something] for quad ranks, 2Rx[something for dual, and 1Rx[something] for single.
