☑️ Key Features
☑️ Unlocked K-series multiplier for overclocking (requires supported chipset/BIOS)
☑️ 4 cores / 8 threads for strong multitasking and gaming performance
☑️ Intel HD Graphics 4000 onboard graphics support (motherboard video output required)
☑️ DDR3 dual-channel memory support and PCIe 3.0 capability on compatible platforms
⚙️ Fit Notes
- Must be used with an LGA1155 motherboard that supports 3rd Gen (Ivy Bridge) CPUs (BIOS update may be required).
- Overclocking is typically supported on Z-series chipsets; many OEM systems do not allow multiplier overclocking even with a K CPU.
- Use a quality CPU cooler rated for 77W+ and apply fresh thermal compound (recommended: Shin-Etsu G751).
- If you plan to use integrated graphics, confirm your motherboard has the needed display outputs and iGPU support enabled in BIOS.
