メモリ容量

BIOS を 2.0b に更新したら,24GBフルに認識された。(2017-05-01)

メモリスロットが6本あるので、最大で 4GB x 6 = 24GB まで使える。しかし、実際に 4GB SIMM を6本挿してみたが 20GB と認識される。

マニュアルによると、「Memory Mode」の項で設定できるらしいが、実機の BIOS 設定にはこの項がなかった。多分、Sparing になっているのだと思う。

pre> Memory Mode

The options are Independent, Channel Mirror, Lockstep and Sparing.

Independent - All DIMMs are available to the operating system. Channel Mirror - The motherboard maintains two identical copies of all data in memory for redundancy. Lockstep - The motherboard uses two areas of memory to run the same set of operations in parallel. Sparing - Memory sparing occurs when on-demand inactive memory is automatically activated by the system

to temporarily replace failed memory until a service action can be performed
(supported only on 2010 Intel® CoreTM processor family based on the 32nm Intel® microarchitecture).
