Something regarding this was posted in this thread. Try searching for shutdown and see what you get; pretty sure it was in the last 30 pages or so (if you're still on default site settings).

Nobody has provided the consumers a half decent answer as to why RAM speeds are getting hamstringed so much. The most we have gotten is "AGESA code isn't great." That's it.

As I understand it, there is a baseline BIOS code for the chipset that motherboard makers can use as a starting point. Motherboard makers can then make whatever changes/enhancements. Now, in many cases, the baseline code does not change very often, so it just comes down to tweaks the motherboard makers come up with.

In the case of the AM4 platform, because it is so new and still not mature, that baseline code is getting regular updates. AMD has even talked about it to the public, and has stated that they have updates lined up that will be sent out to motherboard makers. What works and does not when it comes to RAM is a combination of that baseline code and the motherboard makers. We have seen a significant improvement in 0079-0083 so far, but that is just the tip of the iceberg. The May update is supposed to include RAM support updates from AMD, meaning 1-3 weeks after motherboard makers get it, new BIOS updates will be released that incorporate the updates.

Remember, the CPU itself has the memory controller, but how that connects to the physical memory modules is where the problems come in.

Have you tried to disable fast boot in Windows, shut down(and see it shuts down properly), then boot again, turn on fast boot, and see if that fixes it?

Might be worth setting that manually.

It was off by quite a bit (setup for 1.385 at around .69). I set the dram vboot .1 higher than the dram and it booted without issue. I dont know if it has been doing that lately with my other settings or coincidence but at least it is correct now regardless. I'll have to try it on auto and see what happens.

Is it possible to get my Corsair Vengance 3000 C15 32GB (2x16GB) to higher speed than 2666 with BIOS 0081 or 0083? would i need to use bclk to oc?

also how can some RAM overclock to 3200 with 120 bclk and 26.66 RAM multiplier, but not 100 bclk with 32 RAM multiplier? will this ever change?

There is no way to know unless you try. From the looks of it, 0081 is going to become the next official BIOS but 0082 has some RAM compatibility updates in it (also present in 0083)

I just flashed from 1001 to 0081 and my F4-3200C14D-16GTZ's finally booted into 3200MHz!

Some interesting notes:
  • All I did was use DOCP Standard, which sets bclck to 100, DRAM to 1.35v, and timings of 14-14-14-34. All remaining settings were left at default.
  • The RAM is using 1T
  • Previously, I was stuck on 2933MHz using a manually set CPU SOC voltage of 1.0v, however, even 1.15v did not help (nor did 1.40v DRAMv).
  • HWiNFO is currently reporting a average CPU SOC voltage of 1.137v.

It's Asus C6H, not CH6; Fighting the wars that matter.

I have the same kit. And i have been trying for hours at end. Cant get it past 2666 on normal straps at least.
bclk might yield better ressult dont know, not gonna try it untill the extended mem support bios has been released and these still fail on me.

(0083)

I noticed the same regarding SoC voltage. Using mostly stock / auto settings and only setting up RAM to 3200CL14 it seems like like is ~1.15V SoC.
