I have and am running a Sempron 1.8GHz in it.

I am not an AMD person - Most Dell boards are Intel. Any useful info is appreciated.

Bad news - only AMD K8 processors are supported by this BIOS.

Can you add support to the BIOS or is it a chipset limit?

[DeathBringer]

It's the hardware limit of this motherboard.

8GB RAM on a single core Sempron hahaha

Windows 10 doesn't run bad, I am surprised.

What is the fastest CPU for this motherboard? Any overclocking in BIOS? Quad core support?

What chipset is it?
