I did read about the Spectre / Meltdown mitigation, and from what I understood you need:
When will Intel release patches for their desktop mainboards? I found nothing clear/official regarding those boards, and I do have a DH87RL that could really benefit from that.
Intel committed to delivering updates for all affected products by the end of the month. Watch the downloads page for your board for the release of an updated BIOS. It should appear sometime in the next few weeks.
