Dell 530 manual Sample Configurations, Total Memory Riser Board a Riser Board B Socket

•Memory sockets on the riser boards must be upgraded in matched pairs. In other words, two sockets in a pair must contain modules of identical capacity, number of components, and speed. See "Memory Riser Board Components" to identify pairs of sockets.

•Not all memory sockets on the memory riser boards need to be populated: if one or more pairs of memory sockets contain RIMMs, then the next pair must contain CRIMMs, and the remaining pair(s) can be empty. As another example, if the first and second pairs of memory sockets on the riser boards contain RIMMs, then the third pair must contain CRIMMs, and the fourth pair can remain empty.

•Mixed pairs of error checking and correction (ECC) and non-ECC modules all function as non-ECC.

•The optional memory riser boards only support PC800 memory modules.

NOTE: For more information on upgrading system memory or on addressing memory with 4-GB configurations, see the User’s Guide. You can access this document from the Dell Precision ResourceCD or from the User’s Guides icon on your desktop if you have not reinstalled your operating system.
