Prologue -
I've been using X79 the past 6 years - 3820 then 3930k. With 2133 4x4gb GSkill. On ASRock x79 Extreme 4 then Extreme 6. Then P9X79 Pro. On CM Hyper 412 then H110iGT.
OC was easy - ram - just used XMP. CPU - just used ASRock AXTU. Ran 3930k at 4.2 for year - quiet and cool, but OC helped with rendering.
I got the Asus mobo after the Extreme 6 died. But then had to RMA the Asus board because a usb3 connector pin was broke. I didn't want to wait for the RMA so I bought into Ryzen.
ASRock X370 Taichi
R7-1700
GSkill 2x8gb 3200-14 (FlareX)
The Ryzen stuff has been a pain in the butt. And I see others have had the same problems. I thought I'd get the GN community to help each other with Ryzen problems. So I started this thread. i7Baby

My experience with Ryzen so far.
I had no problems booting to Windows first time I started my PC.
I then found that my bios was only at P1.50 and that ASRock had 2.30. So I downloaded 2.30 and copied to usb, re-started into bios and selected Flash install and selected the file on the usb. 10 mins later 2.30 was installed. .
Next time I booted into bios and set CPU to 3500 and Vcore to 1.1000. This resulted in 3200MHz(?) being seen in Windows. I upped the Voltage by another 0.1V but got the same result. I then downloaded ASRock's A-Tuning software. I set 3500MHz in A-Tuning and it worked well. I tested with Cinebench and it ran OK. I later went to 3700MHz with an 0.01825V offset. Again it worked fine.
I went back into bios and enabled XMP (Profile 1) - which worked according to CPU-Z. But I checked a day later and I was only running at 2400MHz. So I went back to bios and upped the dramm voltage from 1.35 to 1.36V. This worked OK. But then a day later it was back at 1200/2400 and then CPU-Z wouldn't read it at all. But Corsair link would.
Then I saw ASRock had gone to bios 2.40. So I again updated bios, left the CPU as is in bios, enabled XMP and upped the cpu speed back to 3700MHz in A-Tuning. (A month later I did the same for bios 3.00.) This went fine for 2 days then when I went into Windows A-Tuning came up with a divide by zero error and stopped working - yet still my cpu is running at 3700MHz.
The booklet that came with the motherboard for bios is extremely sparse - doesn't give any definition to any of the fields - what they do, recommended settings or how they affect other settings.
So I've been looking on the web. Overclockers.au has a good Ryzen thread (85 pages!). Tom Logan (OC3D TV) has some good YouTube videos. Reddit has a lot of threads with some clues. But nothing definitive eg
LLC - what should you set it to? Default level seems to be 5. I think LLC adds more voltage to improve stability. A lot of people are setting it to level 2 or 3.
CPU overclocking - what do you NEED to do in bios? What else can you do to help?
RAM - is XMP enough? Are looser timings helpful? More voltage?

WHAT PROBLEMS AND SOLUTIONS HAVE YOU FOUND?

Questions to ASRock -

Can you provide detail of Dr Debug codes? Perhaps add them to the Ryzen mobo manual as you have done before.
eg I tried Manual CPU OC at 4000MHz from 1.395 to 1.4625V in 0.0625 steps. I just kept getting code 78.

Can you update A-Tuning so that Performance Mode, Advanced EZ OC actually IS supported?

Can you update your bios manual so that every field isn't just named but also explained?

The Taichi (Bios 2.40 and 3.00) I've got sometimes (1 out of 20) 'forgets' the bios settings last loaded, it goes into memory training then runs at 3000MHz. Can you investigate and fix? (Flat battery on a new motherboard?)

Why can't fixed voltages be used for overclocking?

Why is CPU voltage limited to 1.425? (Ryzen Master allows more)

I just found AMD Ryzen overclocking guide - www.amd.com/system/files/2017-03/AMD-Ryz...king-Users-Guide.pdf - for Ryzen Master.
RYZEN MASTER does CPU OC OK, but only OCs RAM up to what XMP will do.

You need to enable HPET (with AMD batch file via CMD) and go into W10 Settings, Power Options, Power Button and disable Fast Boot. And use AMD's Ryzen Balanced Power Plan - min processor state is 90% (can it be decreased?)

OCing was pretty easy; just time consuming (counting shutdowns, CLR CMOSs and restarts). But the RAM timings are left very loose - my 3200/14-14-14-34 was running at 3200/16-16-16-39 - which dropped my Cinebench scores considerably. This was max for all CPU settings.

I found www.youtube.com/watch?v=dXq7TqvTOj0&t=340s helpful to get started.

3200 ram running at 16 cas seems to knock off 100 Cinebench R15 points from 3200-14. So bios OC gets a meaningfully better ram contribution to Cinebench R15 scores.

Now I found I can OC the CPU via bios if I reset to default values first.

I changed CPU Frequency & Voltage from Auto to Manual
I then changed Frequency to 3700
and I changed Voltage to 1.225V

and I changed Memory from Auto to XMP Profile 1

I have a feeling that both ASRock A-Tuning and Ryzen Master make unseen alterations to bios settings that need resetting in bios before you can try OC in bios yourself.

My next step was -
From Vcore=1.225 & Frequency = 3700 which resulted in Cinebench 1604 and CPU at 40C
to
Vcore = 1.3000 & Frequency = 3800 which resulted in Cinebench = 1640 and CPU at 45C

Edit - a day later, the PC stopped booting, going into a bios loop but didn't finish posting. After 10 manual restarts, I got it to post, hopped into bios, reset to defaults (f9), reset ram to XMP Profile 1 (3200-14) and reset the CPU to This email address is being protected from spambots. You need JavaScript enabled to view it. - which now posts and boots.
So I gather 1.3000v at 3800MHz is too low voltage.
Later - tried This email address is being protected from spambots. You need JavaScript enabled to view it. - 3 x 3 beeps then 2 x1 beep then found running at 3200MHz and 1200MHz ram
Restart into bios, set to default (F9), set XMP again, set This email address is being protected from spambots. You need JavaScript enabled to view it. again, save and exit (F10).
CPU-Z idle 3800MHz, 22C, 0.864 to 2.344V. Cinebench 1.344V 1633 score, 49.9C.
Looks like can't just change a bios setting, you have to reset to defaults then reset bios.

Just watched Buildzoids YouTube on the Taichi - www.youtube.com/watch?v=6HJwBMOr0g4&t=73s

It helps fill in some of the gaps.

And then used the offset voltage method per www.youtube.com/watch?v=TnFHEaSC4zM to get -

3900MHz @ 0.2v offset (nom 1.38125V) at idle runs at 24C (under H110iGT) and voltage varies from 1.184 to 1.376V. AMD say not to go over 1.35V apparently.

In Cinebench scored 1667 @ 3900MHz running 0.2v offset and got to 55.8C

I'll leave that setting for a while to see if I find other problems. Next I might play with the Load Level Calibrations (LLC). See www.anandtech.com/show/2404/5 for Vdroop, LLC and VRM interaction.

When running Cinebench, the CPU Vcore dropped from the 1.38125 (0.2v offset) to 1.375V. This voltage drop is termed Vdroop. Its a bit like cranking a car engine over and the battery voltage drops. This time though it's the VRM voltage.
The LLC has 5 levels with the Taichi. The default is level 5 - virtually has no impact to Vcore. The higher levels attempt to keep Vcore nearly constant. Most people seem to use Level 2 or 3. Level 1 makes the VRM work harder to keep the voltage up.
And now I've changed my mind - www.youtube.com/watch?v=_ic5d5qAhBU - to then go from level 5 back to level 1 or 2.

Hmm - I seem to be stuck at 3900MHz. Even 3950 bios gets stuck at error 78 (P state?). Bios won't allow more than 1.425V or 0.3V offset for Vcore. I'll keep trying. 3900 is OK though - High Cinebench score and not too hot.
ANY NEW IDEAS?

Couple of other things - Set up -
* According to Ryzen Master instructions, HPET should be enabled - by downloading their chipset (v17.10) and running the HPET batch file. On Reddit, posters are saying that it should not be enabled(?)
* The same instructions say to use a High Performance Power Plan in Windows. But also to use Ryzen Balanced Power Plan (using the chipset drivers above) and to set Processor minimum to 5% (which only a Windows Balanced Power Plan allows you to do).
* You need to disable Fast Boot in Windows Settings, Power Plans, Power Button settings.
* Some people say to disable Cool n Quiet (in Bios). But I'm not sure if for all overclocks or only extreme overclocks.
ANY OPINIONS?

I had a go at fine tuning my results -

1. I used XMP Profile 1 and level 3 LLC for CPU and SoC/DRAM on all trials
2. I couldn't get past 3950MHz @ 0.20625V Offset. This gave me 22.6C at idle and 55.6C with Cinebench
3. 3900 @ 0.18750 Offset seems like a good setting even for everyday use - 23.6C idle and 53.5C Cinebench
4. I got 3800 @ 0.12500v offset which gave me a 21.9C idle and 48.6C in Cinebench
5. Using Offset seems to allow the CPU to idle.
6. I probably should also test with something more severe than Cinebench eg Aida or OCCT or even Prime.
7. I couldn't get the default to boost to 3700. So I added a fixed voltage profile of 3700 @1.20000V (offset didn't seem to work)
8. I tried 3975 at all the all the offset voltages from 0.2v to 0.3v (ASRock's max) And I tried Fixed voltages up to 1.42500 (also max). I did get it to post, boot and run at 3975 at 0.21875v but Cinebench gave a black screen.
9. Testing also included seeing if it would post. ASRock's motherboard training kicked in quite often getting 3 x 3 beeps then a 1 beep before it would post. Quite often it got stuck at code 78. Sometimes it would post and run but after a shutdown, it wouldn't post again.
10. CPU-Z gave errors now and again - couldn't see Vcore or any RAM detail. Cinebench sometimes quoted the wrong CPU frequency.

If you can provide further insight, I'm happy to learn from others' mistakes. Let me know.
