Common Options : Enabled, Disabled
Chipkill is an enhanced ECC (Error Checking and Correcting) technology developed by IBM. Like standard ECC, Chipkill can only be enabled if your system has two active ECC memory channels.
This BIOS feature controls the memory controller's Chipkill functionality.
When enabled, the memory controller will use Chipkill to detect single-symbol and double-symbol errors, and correct single-symbol errors.
When disabled, the memory controller will not use Chipkill. Instead, it will perform standard ECC to detect single-bit and double-bit errors, and correct single-bit errors.
If you already spent so much money buying ECC memory and a motherboard that supports Chipkill, you should definitely enable this BIOS feature. Chipkill offers a much greater level of data integrity than standard ECC.
You should only disable this BIOS feature if your system only uses a single ECC module.
