DELL T310机器加内存条后，内存频率降低了？

Hello,这是正常的现象，如下官方解析：

The memory speed of each channel depends on the memory configuration:

• For single or dual-rank memory modules:
  • One memory module per channel supports up to 1333MHz
  • Two memory modules per channel supports up to 1066MHz
• For quad-rank memory modules:
  • One memory module per channel supports up to 1066Mhz
  • Two memory modules per channel are limited to 800MHz, regardless of memory module speed.

If memory modules with different speeds are installed, they will operate at the speed of the slowest installed memory module(s).

The table below shows the memory populations and the maximum frequency achievable for that configuration.
