With the C6H which got bricked, I ran G.SKill b-die 2x 16GB 3400 14-14-14-34 1.35V, at full spec but with 1.4V

Now with the G7K, I'm running G.Skill b-die 2x 8GB 3866 18-19-19-19-39 1.35V running at 3440 MHz (ref clock 107) 16-16-16-36 1.4V.

Setting the ref clock to higher values e.g. 109 causes the ram to run in "safety mode" where the system takes 5 minutes to boot.
Setting even higher values, like 129, which my C6H bricked on, causes the G7K to say "system could not boot due to misconfiguration".

I think last we spoke i told you not to touch cpu oc and just touch the ram which you did, since you are having the same issues total shot in the dark its memory related.

Once you get it to boot just load optimized default and run it that way a couple days see if you get the same problem. Might just be too high of a ram oc.

Since the kit is rated for 3866, it's not "too high of a ram oc" per se. Due to memory controller limits, we have to touch the ref clock to run the memory at rated. Then other components on the board or soc or whatever can not handle the increased ref clock and the board goes "nope, I'm out of here!".

Would love to know if the bios updates on the C6H since 0902 actually fixed the issue. Even if I were to run seemingly crazy high ram oc's with increased ref clock... hm, I might get another C6H tongue.gif


I am running ref clock 100 now with cpu at 4.0GHz and the ram at its rated timings, but downclocked to ryzen's max memory multiplier, so 3200MHz.

Why can't people just leave the memory alone at a safe 2666 until further optimizations from bios xD??? idk how many cases of dead ram, or blown mobo's from people trying to push bleeding edge now.

because that is what we do. rolleyes.gif

If nobody pushed the hardware and noticed those issues, mb manufacturers would not know about the problem.

Mine was rated at 3200 and could only run at 2666, I'm not going to run destroying my mobo for a extra memory mhz especially on immature bioses, thats just asking for trouble.

Oh they already know about the problems its why they push out beta BIOSes for people to try out. To high of a soc voltage isn't recommended either.

well, now we know. if it wasnt for threads like this, we would not.

Oh no i think we knew already when before the CPU was even released we were told 3200mhz would be the max for now, seems to be an AMD memory controller issue along with the BIOS.

Yes some people are seeing above 3200mhz with upped voltages but again how safe is it? Me, im fine trying stuff out i dont mind, but not at the cost of possibly bricking my board lol.

and then motherboard manufacturers put external clock generators on the board.

all or nothing biggrin.gif

It's one thing to push things, and another for pushing things blindly without understanding the limits of the platform.
