I'm trying to upgrade a Dell 2850 GII from 8 to 12GB RAM.  The MoBo allows up to 16GB and currently has 4-2GB sticks of PC2-3200R in slots 1 A&B and 2 A&B.  When I insert two more of the same memory, I get the message that slots 3 A&B only support single rank DIMMs, and I should remove the dual rank DIMMs.  If this memory works for the rest of the memory, what memory do I need to use in these last two slots?  

DIMM 3A and B only support single rank memory

Components are those devices that are internal to a computer -- the PC boards, the central processor (CPU), the memory (RAM), disk and video controllers and so on.

Components

Servers are computing devices that are similar to desktop computers in that they have the same basic components, but are significantly different in size, configuration and purpose. Servers are usually accessed over a network, and many run unattended, without a computer monitor, input device, audio hardware or USB interfaces. Many servers do not have a graphical user interface (GUI), and are configured and managed remotely. Servers typically include hardware redundancy such as dual power supplies, RAID disk systems, and ECC memory, along with extensive pre-boot memory testing and verification. Critical components might be hot swappable, and to guard against overheating, servers might have more powerful fans or use water cooling.
