Thank You both. I thought it to be very strange the Asus rep said they were different... but at the same time their are 2 different titles for Bios/drivers etc, so I've only upgraded to the latest bios under the AC/4 menu.
Did they ever fix the x79 DDR3 2400mhz memory problem in the Bios? That's what I have for memory and was very expensive but after reading a lot of the other thread, now I see why my memory isn't seen as 2400, only 1333!
abvolt, you have the same as me, R4BE/4930K/G.skill 2400 64g (cost too much not to be able to run at that speed, %760.00)/Corsair AX-1200i/Crucial M-500 960g SSD, updated Firmware/Asus Matrix Platinum HD-7970 x2 (some say Crossfire's enabled while others do not *scratches head*/Corsair H100i/Corsair H-2100 Headset/Corsair K-95 gaming keyboard.... I suppose I should put that in my profile...lol II'll update it soon but I'm very curious if they've fixed the issue for the 2400mhz ram?
