Re: RX4640 Memory Slots

Memory must be installed in quads, 4 modules at a time in the same size. This is mandatory, e.g. in 0a, 0b, 0c and 0d.

Hope this helps!
Regards
Torsten.

Re: RX4640 Memory Slots

Nelson,

From page 55 of the guide:

You may install additional DIMMs into both sixteen and thirty-two DIMM boards. When adding DIMMs, you must use a minimum of four like sized DIMMs in the next available quad.

Supported DIMM Sizes

Supported DIMM sizes are 256MB, 512MB, 1GB, 2GB, or 4GB. Dissimilar DIMM sizes may be used across the entire extender board but all four DIMMs in each quad must match. For cooling purposes, DIMM fillers must be used in some slots.
