To get my cpu to 3.9 ghz I need already 1.43 volt and to get to 3.95 ghz, I needed 1.5 volt. I'm on liquid cooling, temps are fine but I'm not risking these high voltages for daily use.
3.8 ghz is the sweetspot for my Ryzen 1700 cpu.

I was seeing similar requirements (needing 1.3875v to hit anything over 3.85Ghz...) but decided to try again after having upgraded to the 1.40 BIOS and was surprised I could hit 3.9Ghz at the voltages I hit. My CPU is the 1700x if that makes any difference.

Interesting...... I'm still on beta 1.45.
The only reason I'm still on beta 1.45 is because my 4 DIMMS RAM are very smooth at 2666mhz (14-16-16-34).
But now you're telling me that your cpu performs better on the official 1.4 Bios. Might try that.........

3.8 ghz is the sweetspot for my Ryzen 1700 cpu.

Probably due to llc at 1. Thats the most droop. If you went to llc4 which is still slight droop or 5 which is totally flat you will probably be stable. Just my thoughts.

Edit. The more drop u got the higher voltage you need. So your 1.4v or whatever might be 1.2 under load. Higher llc should keep that stable. I run 4... But think i will try 5 to test how flat it stays switching loads.

I took a very measured approach. I started at 1.3250v and walked through LLC 4 - LLC1, upped voltage minimally and repeated. I was nearly stable starting at 1.3375v but couldn't pass AIDA64 for more than a minute, tops. At 1.3625v I couldn't get past 2 minutes until I went with LLC1. All lower settings failed. I suspect it's because I am on the "hairy edge" of the minimum voltage when AIDA stresses the cache. The lower LLC settings were pretty damned stable with voltages, but were always just a tad below 1.362 until I got to LLC1...

So I am sticking with that. I would rather stick with an aggressive LLC setting than up the voltage a tad more.

1700 at 3.8ghz at 1.225v LLC1 here smile.gif 4.0 at 1.43, 4.1 at 1.5 on Air Noctua C14.

This 1.4 bios still handles my RAM worse than 1.31. Will just wait for next official bios.

Btw which beta had the adjustable bckl and where can I get this? I don't see this adjustment on the official 1.4.

On the official 1.4 Bios now. Can confirm that I need all my previous beta bios settings for the sweetspot. (So I think it's the same bios)
I need 1.3875 volt to get my Ryzen 1700 3.8 ghz perform at it's best with the highest score in cinebench (lower voltage runs cinebench but a lower score. 1.3875v gives the highest score, 1.4 volt gives also a lower score. Tried it multiple times)

LLC1 or 2 is also the best settings for the best performance.

3.9 ghz is possible but I need more then 1.4 volt, (cinebench runs with LLC1 but stops halfway through, LLC4 won't even start cinebench) (LLC1 gives, 1.41 volt, LLC4 gives 1.408 volt)
I need 1.43 volt to run 3.9 ghz. So it's all the same as in the beta bios 1.45.

Running my Ryzen 1700 now at 3.8 ghz at 1.3875v with 4 DIMMS RAM at 2666mhz (14-16-16-34) Cinebench score: 1710 points.

Enough tweaking for today......

This 1.4 bios still handles my RAM worse than 1.31. Will just wait for next official bios.

Btw which beta had the adjustable bckl and where can I get this? I don't see this adjustment on the official 1.4.

You've got a good cpu.
I thought beta 1.41 had the bckl but please don't go to that Bios it could brick your board. It was not on beta 1.45.

Look at this guy he runs the 1600x at 4.0 ghz with cpu voltage on auto running cinebench, no problem. In cpu-z it shows 4 ghz at 0.4 to 0.6 volts. In another video he does the same with the 1400 at 4ghz with again the cpu voltage on auto. Wow.

https://www.youtube.com/watch?v=T5H3xOx_avY

min 16.22 shows the cpu-z

The other difference this time is I upped my NB to 1.05v (not higher based on info from Chew). That may, or may not, have made a difference.

I was already on 1.15v with the NB.(What I heard it has an influence on your RAM, it works for me)
But I think you're right that made a difference here as well.
My cpu hits the wall earlier then yours but I'm fine with my cpu. Can get it to 3850ghz below 1.4 volt, no problem.
Can get it to 4 ghz with 1.5v but I can only get into windows and nothing more or it will crash lol My highest cinebench score is on 3950ghz at 1.5v score 1734.
