Athlon 4 SSED Instruction

Common Options : Enabled, Disabled

Quick Review

Beginning with the Palomino core of the Athlon XP (and MP) family of processors, AMD started implementing Intel's SSE instruction set. AMD also added a status bit which tells any querying software that the AMD Athlon XP/MP supports the full SSE instruction set. However, this status bit ends up causing some compatibility issues with the BeOS operating system and some graphics cards.

This is where the Athlon 4 SSED Instruction BIOS feature comes in. This BIOS feature is a simple toggle for the AMD Athlon XP/MP's SSE status bit.

When enabled, the BIOS will enable the SSE status bit. Querying software will recognize the processor as an SSE-compatible processor. This allows the processor to take advantage of SSE-optimized software.

When disabled, the BIOS will disable the SSE status bit. Querying software will not recognize the processor as an SSE-compatible processor. The processor can only take advantage of Enhanced 3DNow!-optimized software.

By default, this BIOS feature is set to Enabled, which allows for optimal performance with SSE-optimized software. It is highly recommended that you leave it at the default setting of Enabled.

You should disable this BIOS feature only if you are facing compatibility issues with the SSE status bit.
