BIOS Update Help

[Aidan1]

My pc build on partpicker says "Some Intel H81 chipset motherboards may need a BIOS update prior to using Haswell Refresh CPUs." How will this effect my pc build?

If you have not bought the parts yet, I would suggest an H87 or H97 motherboard. the H81 boards do have a history of issues with the 1150 socket chips. The newer boards are far less of a hassle.

It means the BIOS needs to be at a specific version for your CPU to work. The thing is, you usually need a supported CPU to be installed to update the BIOS. You may get lucky and get a board with the correct BIOS version already installed, or you may be left with a board and a CPU that you can't use.

MSI's CPU support list, the last column is the required BIOS version:

You'd be best off going with a board with a 9-series chipset, those support Haswell-R out of the box. Preferably a Z97 board if you plan on overclocking that CPU. This one for example:

A BIOS update may still be required to get the most out of your CPU, but you'll definitely be able to update the BIOS with your G3258.

I tweeked your build a little. I swapped out the Motherboard, suggested a faster chip that I think might serve you better, I took off the Hyper212 EVO because as much as I love that chip, I dont really think you need it for an i3. I swapped out the Power supply for something with a better reputation. let me know what you think.
