Should I upgrade my CPU or flash the BIOS to overclock?

[IsaacThePooper]

I currently have a build I built off of cheap eBay parts, here's the specs:

- Xeon E5-2660

- 32GB DDR3-1333

- Beyang "X79" Chinese Motherboard E5 VER 3.2S1

- RX 570 8GB

- Corsair CX450 (2017)

 

The CPU is a bit lacking in single-threaded performance in games, I'm eyeing on the Xeon E5-2690 that's going for ~$90 on eBay. So I'm looking to upgrade this system but after doing a bit of research, the 2690 is just a higher clocked 2660. I can't currently overclock my CPU on this Beyang motherboard, but I have seen options to flash the BIOS, although I still don't know which flashing tool/files to use for this specific motherboard. I've seen people overclock the 2660 to 3.9GHz, which is .1 more than the 2690's boost clock. 

 

So does anyone know the specific tools and files I need to flash the BIOS on the Beyang "X79" E5 VER 3.2S1 motherboard?

Are there any other good LGA 2011 CPU's that would be a worthy upgrade (maybe the Xeon E5-2667 V2) ? I haven't seen a whole lot of benchmarks/information online for v2 Xeon CPU's for single-threaded tasks and multiple "CPU comparison" websites show different results.

You could flash your bios, you could also fry your motherboards VRM. Those boards are a little cheaply made to be able to OC a CPU.

I have a 40mm fan blowing on the VRM currently lol

 

But do you know which files or guides out there that would be needed to flash my specific motherboard?

Not the foggiest, sorry.
