Hello,
first of all thanks for help in advance.
I just bought a nice machine: The already mentioned M/B with processor i7 6700k + 64GB of Corsair DDR4 Vengeance LED. The problem is that I cannot raise the clock up to 3000 Mhz as expected.
The best I could do is 2500 Mhz at 1.3v using XMP and changing the multiplier. And this worked only after I upgraded the bios to F20b before that it was impossible. So definitely there is some sort of compatibility issues.
The ram is CMU32GX4M2C300015 with latency: 15-17-17-35
I tried everything, setting it manually without XMP or with XMP or partially XMP + manual settings, no wait, if lucky sometimes it would boot up at 1.35v @ 3000mhz but it is too unstable, it freezes and then reboot without post. I need to reset the CMOS and start over. I tried different volts.
I know that ram is not in the compatible list, so I also got some other RAM always from corsair this time listed in that list, and still no work. I tried the Vengeace lpx CMK32GX4M2B3000C15 the same problem. It works great at 2133 and maximum up to 2500 mhz stable.
I do not know what to do. I know that it is not too much important in the end the difference in not noticeable.
Anyway if you have any ideas I am open to listen. Thank you
