Memory Ranks - Intel E7320/E7520 Chipset-based Servers
The new servers utilizing Intel's E7320/E7520 chipset (code-named "Lindenhurst") support PC2100, PC2700, and PC2-3200 memory. Memory Ranks limitations apply only to PC2700 and PC2-3200.
Q: How do Intel Lindenhurst servers limit ranks?
The number of ranks is important based upon the server's memory speed:
- If PC2100 memory is used, the number of ranks is not critical and either single- or dual-rank memory module pairs can be used.
- If PC2700 or PC2-3200 memory is used, there is a maximum of 8 ranks per server. For example, if two pairs of dual-rank memory modules are inserted into the memory sockets, that would add up to 8 ranks (4 modules x 2-ranks each = 8 ranks); in this case, empty sockets cannot be used for upgrading memory.
