My G.Skill F4-3200C16D-16GTZB kit now works with D.O.C.P standard profile @ 3200Mhz out the box with BIOS 0083! The 1T BIOSes won't even get me to 2666Mhz.


That's awesome news, sadly I just started to install the WC and that migh take a while lol. Damn this could have been a great weekend xD

Installed the second 1700x onto the CH6 and something odd sticks right out.
  • First 1700x updating to bios 0081 and all previous ones would have cpu of 1.43v with auto volts, would spike up to around 1.51v in windows.
  • The second 1700x in cpu auto volts goes straight to 1.351v in the bios and windows with max of 1.37, runs much cooler by a long shot
Why the big various between two same model cpu's? First one was a very poor overclocker but had no problem running G-Skill ram at rated 3200 speed. 2nd 1700x also does not appear to have issue running at 3200 speed either. I have not OC the second one yet, stress testing at default now to make sure it is stable at stock.

As a note: Bought second 1700x due to I accidentally overvolted first 1700x to like 1.8v (still works but more limited).

Anyways I just find this rather odd to see such a very big difference.

Why is the L3 cache throughput much worse?

- pstate 0 multiplier cant go below 32 with fid 80, so for example 4 GHz with 135 MHz refclock is not possible atm
- offset voltage with pstate oc also worked as expected, now running + 0.325V for 1.4V under load
- ram oc is now stable @ 3600MHz 14-14-14-34 1.5V, where with the old microcode it would only pass memory training every third time and then not really be stable (so I had to run 3200 14-34 with 1002)
- ram training completes with 14-14-14-34 timings and 1.5V at speeds up to 3775MHz

- !!! ram oc over 3650 MHz is not stable at all in windows and causes all kinds of memory errors! I'm getting blue screens with "memory_management", "page_fault_on_nonpage_memory", registry corruption, windows lock screen image changing colors, all kinds of the weirdest data corruption.
what I tried to mitigate this behavior:
- increase ram voltage up to 1.7V
- increase soc voltage up to 1.2V
- increase core voltage up to 1.5V
- set boot voltage up to 1.7V
- disable bankgroupswap
- setting 3700MHz with various memory multipliers and refclocks
- losen ram timings up to 20-20-20-40
- all combinations of the above
nothing worked


tldr 3650 MHz ram clock atm marks the tipping point from awesome performance to total madness and data corruption in windows.


If you have important data on your system, do not use these "testing" bioses and stay on the official version. Dont be mad, if your Windows install just craps the bed.

oh and here is a screenshot of my 24/7 with non-stock ref clock pstate oc, offset vcore and 3600MHz ram (no performance bias): Warning: Spoiler! (Click to show)

Dude, you are going to fry your ram. I'm trying to stabalize a G.skill 3600 C16 8X2 kit at 3450 mhz and is taking about 1.4v, check in Hwinfo, dimm temp is like 58C and burning to the touch. I can't imagine how hot yours are. What dimm temp do you have in Hwinfo?

Can you take a look at this? read the description

ps: I did a windows reset before doing this video.

Curious. Where were the two made?

Just switched to BIOS 0079. Seems to boot a bit faster, and seems to complain less about my RAM (Corsair Vengeance LPX 3200). After setting D.O.C.P. Standard @3200, it booted into Windows without issue. I haven't done any cold boots or sleep cycles, so I'm not 100% sure if this BIOS is better than 1002.

On a side note, does anyone actually understand the new AMD Ryzen Power Profile? Why is it that the CPU sits permanently at P-State 0? Why does the CPU even have other P-States if AMD doesn't want you to use them? What exactly is happening? Does it actually downclock but HWinfo doesn't register it happening?

Thermistor in the CPU socket.

@bluej511

The G.Skill RAM have sensors, Corsair LPX and Crucial Ballistix not for me.

@Mumak

Repeated testing all seems to be working correctly for me on Win 7. I see only minor changes on CPU clock like .x MHz until ~90secs have passed, then it drops to idle. Before UEFI 0079 all sensor data IIRC just stuck for me unless I exit HWiNFO and relaunch or wait >90sec after OS load to launch it.

You want log / debug file?

Add this to autostart

Was the same for me.

You should take another look at your current Sense Skew vs. SIO CPU temp implementation, at least at default/Auto values.

Currently these settings not only lead to the CH6 keeping my 1800X from "soft" throttling (Tctl including offset 95C), but also from "hard" throttling (real CPU temp at 95C).

Even worse, it keeps the CH6 from doing an emergency shutdown due to the SIO CPU temp never reaching 110C. Instead the CPU will start throwing errors (WHEA) and finally crash into Code 8, the latter of which is *not* a full shutdown.

This means that an overheated CPU (over 100C while SIO assumes <75ish C) will still be fed around 1V Vcore even when cooling failed completely, measured via DMM at the socket during Code 8. This seems rather dangerous to me?!

There's no shutdown function based on the SIO temp, it's all handled by the CPU depending on the Tctl value.

Not possible.

This is very interesting. With Windows 10 Creator's Update, the board will "hard crash" into code 8 when the GPU part of initialization begins. I have an RX460 without external power. What happens is, when windows starts booting, there's a part during which the driver is loaded (the fans spin at max speed for a brief moment and then the system loads). With Anniversary Update, no problem. Everything works. With Creator's update, the board will get into repeated 8 state, and when I observe the card, I can see the GPU fans get a little jolt every second or so, as if trying to spin up again. I rolled back to AU, no problem again. Went to CU - hard crash. Also when this 8 code happens, I can't do anything. Safe boot doesn't work, boot retry doesn't work - I have to clear cmos and then try it, but anything other than the default values will always result in code 8 again - and default values do half the time.

I tested this twice (reinstalling and uninstalling CU) and it's always the same; so I doubt it's an accident.

@elmor any idea why Creator's Update would be crashing my C6H ?

Sounds like an AMD GPU driver issue with the new MS code.

If we could we would.

Can you list Aura software version and show the Main tab in the BIOS showing BIOS & iROG versions? Which strip or chassi is it you're connecting to the RGB header? As you say it looks like Green/Blue pins are inverted, but strange that it's working in calibration. Looks like a very nice setup there smile.gif

Here we got with 1T and 3600mhz so I have obtained my 3600mhz on 0083 and 0082 I did bump the voltage a little on 1T
Bios 0082
Trident Z RGB 3600mhz 16-16-16-16-36-2T 1.4v
1700 3.96ghz 1.425v no LLC
Gpu: Gen3 and HWinfo is showing 8GT/s

What is the difference between 0079 and 0081? What is the ProcODT set at for 0079?
