#4452 provides 2 GB DDR Main Storage (DDR1 CCIN 309D) and ships with four 512 MB DIMMs for a total of 2 GB. The 4452-9406 feature provides 2 GB DDR-1 Main Storage for the iSeries Model 570.
The Model 570 offers pluggable DIMMs for memory. Each 0/2-way processor card contains eight slots for up to eight pluggable DIMMs. The minimum memory for a for a Model 570 is 2 GB. The maximum memory capacity depends upon the number of processors ordered for the system and on the type of memory and functionality required.
The rules for mixing and matching DIMMs are:
- Install memory DIMMs in quads.
- Quads must be the same DIMM.
- Memory balancing and spreading is required.
