Sad to say I am always the 1st victim of all of their motherboard. I had highlighted this issue of 1600MHZ DDR3 problem with the DH87RL in this forum since 4 Aug and till now I had not get a single answer. I am also the 1st victim in this forum to complain about their horrendous DH77EB with tons of issue with UEFI boot, unable to detect PCIe TV tuner etc. Maybe Intel can hire me as their lead tester to QC their motherboard.
