FAQ: Frequently asked Question

 

Intel Pentium Gold G6405 — FAQ

What is the Intel Pentium Gold G6405?
The Intel Pentium Gold G6405 is a budget-friendly desktop CPU for everyday PCs, featuring 2 cores / 4 threads and a fast 4.10GHz base clock on LGA1200. It’s a great choice for office PCs, home PCs, POS systems, and light multitasking. 
What are the key specs?
• 2 cores / 4 threads
• 4.10GHz base frequency (no Turbo Boost listed)
• 4MB Intel Smart Cache
• 58W TDP
• 14nm (Comet Lake family)
• 16 PCIe 3.0 lanes

Which motherboard socket does it use?
It uses FCLGA1200 (LGA1200). Make sure your motherboard is an LGA1200 model and has BIOS support for the G6405 before building. 
Which chipsets are compatible?
Intel lists compatibility with 400-series desktop chipsets including H410, B460, H470, Z490 (and W480). If you’re buying used/older stock, a BIOS update may be needed. 
Does it have integrated graphics?
Yes — it includes Intel UHD Graphics 610, so you can run a display without a dedicated graphics card (as long as your motherboard has video outputs). 
How much RAM is supported and what memory speed?
Supports up to 128GB across 2 memory channels, with official memory type listed as DDR4-2666. (Higher speeds may be possible on some boards but are not guaranteed.) 
Is it good for gaming?
It can run light/older games and esports titles with a dedicated GPU, but it’s mainly built for everyday computing. For modern AAA gaming and streaming, a Core i3/i5 or higher is usually a better fit.
Is a CPU cooler included in the box?
Many “boxed” G6405 retail packs are listed with a heatsink/cooler included. Always check the exact listing/box contents if you’re comparing OEM vs retail versions. 
What power supply (PSU) do I need?
The CPU is 58W TDP, so it works well with modest PSUs. Choose PSU wattage mainly based on your graphics card (if you add one). 
Does it support 4K output?
Intel lists 4K support for the integrated graphics (depending on motherboard outputs). Max resolutions vary by output type (e.g., HDMI vs DisplayPort). 
Troubleshooting: PC won’t boot / no display
• Confirm your motherboard is LGA1200 and supports G6405 with the correct BIOS
• Try one RAM stick in the recommended slot
• If using iGPU, connect the monitor to the motherboard video output (not a GPU port)
• Clear CMOS and re-test
