D2529 (TX300 S4) Technical Manual 19
Features Main memory
Non-mirrored mode
Using one riser card the module population is as follows:
1A + 1B (minimum configuration) - 2A + 2B - 3A + 3B - 4A + 4B
Using two riser cards the population can be alternating (higher performance) or
consecutive.
Mirrored mode
The mirrored mode requires memory modules in matched sets of four, two in
each riser card.
1A + 1B, 1C + 1D (minimum configuration)
2A + 2B, 2C + 2D (upgrade 1); 3A + 3B, 3C + 3D (upgrade 2); 4A + 4B, 4C + 4D
