I used to be able OC my memory Trident 3200Mhz ryzen to 3600mhz wiht just XMP enabled on my MSI B450 tomohawk now however with the Asus C6H i can't, it just freezes when I'm in games? Any ideas?
I've followed the DRAM calculator and input all the numbers as configured in "SAFE" however it still freezes..

I tried to use previous zen cpu to flash the mobo and now I can't even boot with previous zen cpu. I'm getting 55 qcode error (memory not installed)
ram was working perfectly fine before trying on this mobo
Could repeated boot trial with 07 qcode error / usb flash have broke my ddr4 ram? Is this even possible? or is it just motherboard defect?

SVI2 TFN in HWInfo should be the closest to actual voltage readings based on DMM readings before with our boards (still, depends on the board as well as some might be nearly on point, some under-reading voltage by a bit, and some over-reading by a lot).
Dang, would be nice to be able to run DRAM voltage at 1.9v+ 24/7. It seems my IF is limited to less than 1867 as I get weird performance when I set DRAM to 3733 and IF coupled at 1867 even with loose timings. There's like a weird lag/stutter whenever inside Windows and benchmarks might seem fine initially but then sporadically go up and down. My B-Die can't seem to hold DDR4-3666 at 14-14-14 stable anymore and can only do it at 16-16-16 (was only feeding 1.47v, dropped down to 1.44v now), immediate errors and BSODs now when I try the former (used to be HCI 1100%+) but 16-16-16 is holding at the moment. Not sure about the degradation on my end.
Also, also noticed E1 bug when I manually set PBO. Goes away if I leave the PBO section at default (under AMD Overclocking).

Two questions for 3rd gen ryzen owners...
1. Do you guys set PBO and AutoOC in BIOS? Or using Ryzen Master to do that?
2. Has anyone run into an issue where, once you tell Windows 10 to shutdown, it goes into the steps to shut down, has the "shutting down" screen, monitor turns off, but the PC stays on? I have to physically press the button on my case to shut it down? Any suggestions how to fix that?

DRAM voltage for both was 1.92V, should be able to run lower at 3800. VDDG set to 1V, VSOC on auto. VCORE is -0.1V in offset mode, doesn't go higher than 1.4V, while on auto it boost up to 1.488. But I don't know which software reading to believe in.
Timings are not optimized for sure and there might be couple of wrong ones.
If your cpu vcore is at 1v the thing is running at like 3.5-3.6ghz max. Run cinebench and watch your score drop 1000 points multi & and 100+ single core over stock. If you are not pushing vcore as high as the core vid it's not running anywhere near those frequencies it's reporting. As near as I can figure it reports the frequency it's trying to hit assuming you are supplying enough juice to match the VID voltage.
Cinebench R20 (3800x)
@ 1.22v it claimed it was boosting to 4.6ghz single core and 4.3ghz all core in hwinfo, yet it scored 4000 and 400.
With PBO enabled & auto voltage it scored 5000 (80c)
@ pbo + 1.35v it scored 4900 and 480ish I believe,
@ 3.9ghz locked all core it scored 4500.
@ 4333ghz all core it scored 5223 & around 510 (70c)

Glad to report success with my 3900x.
Just installed it now... was ready for a big ball ache as i have a PETG loop and it takes ages to drain and refill, and if something went wrong and i had to put the 2700x back it takes the same amount of time again!
I followed some advice here... installed the 7201 bios with my 2700x and set dram voltage to 1.4 before installing the 3900x.
Drain loop, installed chip... booted straight up no worries at all.. loaded DCOP to 3200 and my voltages with 4 sticks of Trident Z CL14 Samsung b-die.. booted straight up.. voltage looks great and temps only 35oc at idle which is way better than my old 2700x.. thought i would then even push my luck and overclock the ram to 3600... low and behold instant boot no worries. NEVER been able to do that with my old 1800X or 2700X
Power cycled several times, restarted, cold boots. All perfect so far. Actually the most stable this board has ever been.
Passing every test i can throw at it. and boosting to 4.3 all core on my massive water loop.
Super happy.. my cinebench runs all 100 points higher than all the reviews ive found. and its sitting at 1.4v max.
And i was almost about to order a x570 regardless just because of all the horror stories!

I have been on this motherboard since the origional Ryzen launch, and had a 1700, and now a 2700. I got a trident z 4133 mhz ram kit and since Ryzen launch I have been shredding games with my ram at 3500 mhz at 14-14-14 2T 1.42 volts. Is it even worth the money to upgrade to a 3700x or 3800x considering how fast my ram speed is already? Been very happy with my setup and I game at 4K with a 2080ti so im not too worried about cpu usage since im mostly gpu bound... ( notice I did not use the term cpu bottleneck, haha ) ; ) cpu is sitting comfy at 1.37 volts 4040 mhz atm.

I don't get it... Just leave everything on auto and don't play with cpu settings!
Please note that it is totally normal for your Ryzen to use voltages in a range of 0.200V - 1.500V -- this is the factory operating range of the CPU. It is also totally normal for the temperature to cycle through 10°C swings as boost comes on and off. You will always see these characteristics, as they're intended, so do not be surprised to see such values.
