INSTALLING HARDWARE MEMORY POPULATION RULES
2-24
a*: Supported and Validated
1*: Physical Rank is used to calculate DIMM Capacity.
2*: Supported and validated DRAM Densities are 2Gb and 4Gb.
3*: Command Address Timing is 1N.
4*: The speeds are estimated targets and will be verified through simulation.
5*: QR: For 3DPC – Rank Multiplication (RM) = 2
8R: For 2DPC and 3DPC – Rank Multiplication (RM) = 4
6*: QDP – Quad Die Package DRAM stacking.
DDP – Dual Die Package DRAM stacking.
P – Planer monolithic DRAM Die.
a*: Supported but not validated.
b*: Supported and validated.
c*: Supported with limited validation
1*: Supported DRAM densities are 1Gb, 2Gb, and 4 Gb. Only
2 Gb and 4 Gb are validated by Intel.
2*: Command Address Timing is 1N.
3*: QR RDIMM are supported but only validated by Intel/PMO in a
homogenous environment. The coverage will have limited system
level testing, no signal integrity testing, and no interoperability testing
The passing QR RDIMMs will be web posted.
