Acer AR380 F1 Specifications

Sparing mode:

• In sparing mode, if the system detects degrading memory, the data in the failed channel will be copied

to the spare channel. The failed channel is then isolated and the spare channel becomes active. Any

uncorrectable error detected before the isolation will cause the system to stop normal operation.

• Channel 3 is the spare channel. Therefore, the effective size will be reduced by one-third.

• Follow the population rules described in independent mode.

• Sparing mode needs all three channels to utilize identical DIMMs. 1A, 2A and 3A should be the same

type, size and manufacturer. 1B, 2B and 3B memory should be the same type, size and manufacturer.

1C, 2C and 3C memory should be the same type, size and manufacturer.

• Same rule is applied to CPU2.

• 3 DIMMs per channel configuration is only available for single/dual rank RDIMM.

• Please refer to the User Guide for complete population rules for both single and dual processor

configurations.

Memory Identification

Generally, there is memory information printed on the label of the DIMM, but different vendors may have

different formats. For example:

4GB 2Rx4 PC3-10600R xx xx xxx

1. Density

• 2GB, 4GB, 8GB, 16GB

• Intel

Xeon

5600 series processors support DIMMs organized by 1Gb, 2Gb or 4Gb DRAM chips

2. Rank

• 1R = Single Rank

• 2R = Dual Rank

• 4R = Quad Rank

• Note: if any quad rank DIMM is used, maximum only 2 DIMMs per channel can be supported

3. Bit Organization

• This platform supports x4 and x8

• Note: It is not recommended to mix DIMMs with different bit organizations in one system

4. Speed

• PC3 – 6400 => DDR3- 800

• PC3 – 8500 => DDR3- 1066

• PC3 – 10600 => DDR3- 1333

1 2 ... 11 12 13 14 15 16 17 18 19 20 21 22 23 24
