ASUS B85M-E/CSM + Haswell Refresh ?

[marat85]

Hi, PCPartpicker reports Intel B85 chipset motherboards may need a BIOS update prior to using Haswell Refresh CPUs. Upgrading the BIOS may require a different CPU that is supported by older BIOS revisions.

Do I really have to buy one more Haswell CPU (released earlier back in 2013 apparently) just to get Haswell Refresh CPU 4790K working with this Asus B85M-E or is there any other way?

Thanks

You don't mention what BIOS you currently have. You need BIOS version 2001 or higher for the 4790K.

Before using the Intel 4th Gen Core processors, Asus suggests that you first download the BIOS updater for new Intel 4th Gen Core Processors and then update the BIOS using this tool.

The original BIOS version is the last 4 numbers on a very thin white sticker (bar code ) on the extreme right hand edge of the board, next to the SATA ports or the 24 pin ATX power.
