Mode-Specific Guidelines; Sample Memory Configurations - Dell EMC Storage NX3230 Owner's Manual

在遵循其他記憶體規則的情況下，可以混用不同容量的記憶體模組 (例如，可以混用 4 GB 和 8 GB 記憶體模組)。
•
不支援在系統中混用超過兩種記憶體模組容量。
•
每顆處理器一次裝入四條記憶體模組 (每通道一條 DIMM)，可發揮最大效能。

Mode-specific guidelines

Mode-specific guidelines
Four memory channels are allocated to each processor. The allowable configurations depend on the memory mode selected.
註:
You can mix x4 and x8 DRAM based DIMMs to support RAS features. However, all guidelines for specific RAS
features must be followed. x4 DRAM based DIMMs retain Single Device Data Correction (SDDC) in memory optimized
(independent channel) mode. x8 DRAM based DIMMs need Advanced ECC mode to gain SDDC.

Sample memory configurations

The following tables show sample memory configurations for one and two processor configurations that follow the appropriate memory
guidelines.
註:
1R, 2R, and 4R in the following tables indicate single, dual, and quad-rank DIMMs respectively.
