Hello.   Refer to the diagram below. [IMAGE] For optimal memory configuration, the memory installed on slots on CH0, CH1 and CH2 of CPU1 have to be balanced and hence the same. The same applies to the memory on slots of channels CH0, CH1 and CH2 of CPU2. Therefore, memory on all channels on CPU1 &CPU2 should be the same. You will need to use 4 x16GB and 4 x8GB modules with 16 GB populated on slots with white sleeves and 8 GB on black sleeves while leaving channels CH0 empty (96 GB in total). Otherwise, the configuration will not be supported.   With the above configuration, you can not introduce 4 x8GB modules because now channels CH0 on CPU1 and CPU2 will not be balanced with the rest.   Yes you can, by using 8 x16GB modules which may not be cost effective. Otherwise, purchase 2 additional 16 GB modules and use 6 x16GB and 6 x8GB modules as follows: A1, A2 &A3 and B1, B2 &B3 = 16GB A4, A5 &A6 and B4, B5 &B6 = 8GB This will provide you with total memory capacity of 144 GB
Hi there!I have Dell PowerEdge R610 with 8*8GB RAM on board and decided to add more RAM recently, purchased  4*16GB and now, hosting support have no ideas how to make it 128GB They have tried different configurations of installing the memory into slots, and all memory sticks do not work together. The massage on the screen says that “the server does not support existing configuration of memory.”Currently, they have installed 4x16 and 4x8.. Which give us 96gb. But they say that the rest 4x8GB are incompatible with currently installed. Is this possible at all? The rest of 8gb memory sticks have same speed and type as those, that are currently installedIs there a way to make it 128 ? please advice!
