This is the problem I think. Now why or what causes on mine I need to find out.  Hi Teckie, check with your motherboard manual. For dual channel memory the memory sticks need to be inserted in slots A2 and B2 (the second and four slots starting from the CPU side)

I've tested a K4 with a very similar G.Skill kit and with UEFI 2.5 ran 3066MHz CL14 without any problems, switch your RAM to dual channel and try a 2933MHz divider as a starting point.

Weird arrangement? Dual channel, two channels, are labeled channel A and channel B. How else would you label/identify the two channels?

Channels A and B, or 1 and 2, or left and right, clearly identify which channel is which.

Check a quad/four channel memory board, Intel X99 for example, four memory channels, each channel with two slots, the channels labeled A, B, C, D.

What mother board manufacture is NOT labeling and separating the memory channels into A, B, etc? I cannot think of one mother board I have used, including Asus, Gigabyte, ECS, and Intel, that does not label multiple memory channels in this way. ASRock has used this labeling format for many, many years, if not always. That is clearly shown in the manual.

Yup those are the settings I tried and it did not post either. The only difference here is my R1700X running at 3.9 / 1.3 volts (i tried 1.35 volts and didnt work either)

Is your cpu oc'ed mode or running stock ? and thanks for the info. My R1700 is oc'd to 3800 at 1.3v(haven't played around with trying a lower voltage).
