iSeries 9406 Memory, #3015 8 GB Main Storage 870/890
The #3015 8GB Main Storage Card DRAM PSIMM is used in the Models 870 and 890.
For the Model 870: The #3015 can be placed in an “inside” main storage card slot only (slots 0, 1, 2, and 3). Eight main storage card sockets exist on the backplane of the Model 870.
A maximum of four main storage cards can be placed in the system:
#3015: 8GB Main Storage Card DRAM PSIMM (Inner)
#3017: 32GB Main Storage Card DRAM PSIMM (Inner)
#3020: 4GB Main Storage Card DRAM PSIMM (Inner)
#3035: 16GB Main Storage Card DRAM PSIMM (Inner)
The main storage cards are installed according to the following rules:
- Installed in pairs of equal capacity
- Pairs must plug into memory slots under the same
- Multi-Chip Modules (MCMs). (ie: Slots 0/1, Slots 2/3)
- Mixed storage cards must be of an adjacent incremental capacity. (ie: 4GB and 8GB are allowed, but 4GB and 16GB are not allowed)
- When mixed storage cards are used, lower capacity need not precede higher capacity.
For the Model 890: All main storage cards must be added in Pairs of the same capacity and technology. The slots are arranged in groups of Inner and Outer slots.
24-way processors have 6 memory slots (4 Inner and 2 Outer)
32-way processors have 8 memory slots (4 Inner and 4 Outer)
Inner Slots are slots 0, 1, 2, 3
Outer Slots are slots 4, 5, 6, 7
Inner slots are filled first

The main storage cards are installed according to the following rules:
- Main storage cards are installed in pairs of equal capacity.
- Pairs must plug into slots under the same MCM. (ie: Slots 0/1, Slots 2/3, Slots 4/5, Slots 6/7).
- Mixed storage cards must be of an adjacent incremental capacity. (ie: 4GB and 8GB are allowed, but 4GB and 16GB are not allowed)
- When mixed storage cards are used, lower capacity need not precede higher capacity.
- Maximum of two card sizes on each Model 890.
Important: Fill all slots. An exception is allowed for 16GB on a 24-way processor and for 24GB on a 32-way processor.
Supported on the following systems: 870, 890
