Your Motherboard Socket AM2+/AM3 is too old for any processor to have those newer SSE4.2 Extensions or instruction.
It seems like all AM2 & AM3 processors have SSE4.a CPU Instructions.
But the AM3+ does seem to have CPU Instructions newer then SSE4.a. The AMD FX8350 has the following SSE4 instructions:
| Extensions and Technologies | - MMX instructions
- Extensions to MMX
- SSE / Streaming SIMD Extensions
- SSE2 / Streaming SIMD Extensions 2
- SSE3 / Streaming SIMD Extensions 3
- SSSE3 / Supplemental Streaming SIMD Extensions 3
- SSE4 / SSE4.1 + SSE4.2 / Streaming SIMD Extensions 4 ?
- SSE4a ?
- AES / Advanced Encryption Standard instructions
- AVX / Advanced Vector Extensions
- BMI1 / Bit Manipulation instructions 1
- F16C / 16-bit Floating-Point conversion instructions
- FMA3 / 3-operand Fused Multiply-Add instructions
- FMA4 / 4-operand Fused Multiply-Add instructions
- TBM / Trailing Bit Manipulation instructions
- XOP / eXtended Operations instructions
- AMD64 / AMD 64-bit technology ?
- AMD-V / AMD Virtualization technology
- Turbo Core 3.0 technology

SSE4.2 was introduced in 11/2008. but AMD processor with SSE4.2 was support after 10/2011. So any processor manufacturered after that date will have those extensions included:
SSE4.2 is the second part of SSE4 instruction set. SSE4.2 was first introduced in Intel Nehalem core in November 2008. The first AMD CPUs with SSE 4.2 support were launched in October 2011. These processors used Bulldozer micro-architecture.
