Intel Xeon x5650 overclockable to dell 0k095g?

Hello guys i have to stream before fortnite and i got a rx 590 8gb and i saw the processor as intel xeon x5650 or 5660

In order to get a bottleneck as little as possible, I will try to overclock the CPU, I only know whether this is possible. I have Dell 0k095g as mainboard, so is it possible to overclock on the mainboard, and if so how? And how much gh / z?

Is an OEM board, so rather no. But you can have a look in the BIOS

What does oem mean? And can't I overclock with a program?

OEM = Original Equipment Manufacturer

Actually, overclocking is always done in the BIOS. Maybe you can try Intel XTU, but I don't think that will work
