I think that these 3000 series aren't really something you can put any real logic to. On my 3600X, I have the best results setting both CCX to 4200 @ 1.35v (using Ryzen Master). Under these circumstances I see the best overall performance and numbers, it beats out PBO and even higher clock speeds with stable voltage; going any further or using PBO makes my synthetic and real world numbers go down, not significantly, but they go down nonetheless, even single core loads are very simlar in results when using PBO or the solid 4200. I'm running on an EK Supremacy EVO water block and temps max out around 73-75c (ambient ~28-30c).

I know that AMD probably accounted for it, but doing PBO Max +200 and seeing voltages sit in the 1.43-1.5v range all the time is uncomfortable for me; the negligible increase in performance isn't worth the increased voltages imo.

Guys, do remember that max safe 24/7 voltage for zen 2 is 1.325v. With voltages some of you use (1.4v and up) you will degrade your chip quite fast. I have seen people degrading chips in just a few days.
Are you already seeing degradation with Zen 2 specifically? I'm just puzzled / surprised that there is even evidence of degradation so soon after release.

Any links to this information? As was mentioned, regardless if it was more than needed or not, the VID in the chips have it well over 1.325V already. One would imagine that if 1.325V was true, AMD themselves and the VID in the CPU wouldn't be much over that mark.

I can't say I buy that we've seen degraded chips already... at least not from the ambient crowd. Most of these CPUs can't take more than 1.35V with all cores and threads overclocked in the first place due to thermals... so I wonder how we're seeing it so soon as well when most can't even run it that way.

We are having some hot weather these days - 30c out side and aprox 25c inside - did a couple of ours of gaming ang got these results with Hardware Monitor
127666

79c and a average wall measure of watt totalt ussage of between 415 and 470 watt. I have change my Radeon VII OC to more voltage and i getting better average FPS with it.
127667

127668

Hence the higher total powerdraw

The heat pipe coolers are a refined designed based on the ones you used to get with phenom processors. The thermal performance is actually a lot better though. Over clocking wasn't a thing on those stock heatsinks at the time. Even at 100% fan speed the old ones would be smashed even by the cheap arctic cooling 92mm tower coolers. The current gen ones about about as good as the aforemention 92mm tower heat sink.

Playing around with Memory timings @ DDR voltage 1.39:
127860
127861


CL14 was achieved by dropping from 1800 to 1733 ( DDR4-3466 instead of DDR4-3600 which is written on the sticker).
Anything more (3533) results in 3 bios beeps and board resetting itself.

Seems to complete CineBench, wPrime, the usual stuff, but scores seem to be in the same ballpark.
Little to no effect in CPU-z, anything from DDR4-3000 to DDR4-3600 showed almost identical scores:
127866

I guess this test fits completely in that giant L3 "GameCash"


3DMark on the other hand, especially Fire Strike have increased by 1-2% compared to DDR4-3600 CL16:
https://www.3dmark.com/fs/19987389 ( 20852 ). I think this is the highest score I ever got in this test with the same GPU (GTX 1080)

Also the highest "Memory Write" speed achieved so far in AIDA64 - Over 30000:
127864

Reads are a tad slower than for 3600.

Edit:
Small update, shaved one clock out of the secondaries, booted, running random tests:
127865


Some extra 3D testing and comparison to my previous CPU:
Cloud Gate https://www.3dmark.com/compare/cg/4568226/cg/4373806

Anybody knows what is the voltage limit for Ryzen 3000 chips to run it 24/7 without degradation? Somewhere i read 1.32v
My 3700X runs:
4.1Ghz at 1.23v
4.15Ghz at 1.3v
4.2Ghz needs more than 1.32v to be stable

If you looked at the pages before, what you're doing is wrong.
Don't do manual all-core overclock on these chips, it's pointless in most cases and reduces performance.

Yes, it can do 4.2 on 1.32, but it can also do 4.4 or 4.5 on single thread if you let it... ( so no fixed clock and fixed voltage ), which does matter a lot in games.
That extra 200-300 Mhz can be the difference between dropping below 60 fps and not dropping below 60 fps...

Depending on the quality of the chip you get, what you're saying could also be wrong. While I do agree the difference in performance isn't worth messing with the stock CPU settings, it's still possible to get better depending on the chip quality.

I ended up getting a really poorly binned 3600X, won't break 4250MHz single core at all stock settings, and setting 4200MHz @ 1.3625v improves my scores across the board, single and multi-thread. I also cannot run Infinity Fabric at 1800MHz, if I set 1800MHz on the IF to match a 3600MHz memory clock, it either won't boot, or will crash as soon as I log in, I have to settle at 1767MHz IF with 3533 memory because I got a really poor quality chip.

I am running stock with auto voltage PBOoff and on or auto OC+200mhz didnt notice any difference, 1T boost only up to 4.375Ghz in CB R20, but I am curious to push some all core OC just to see, what it can do.
When I change LLC to higher levels on my Asus TUF X570 it is stable with 4.2ghz 1.325v. I slowly pushing further, traying out every day, but I've noticed, when I bump SOC voltage more then 1.1v it doesnt boot into BIOS I have to clear CMOS.

It's not all about binning it seems, the new AGESA 1.0.0.3ABB made a big difference for me, so update to that once it's available for your board and see if that doesn't make a difference.
Yes, I still don't have a great chip, but it got my chip to 4.5GHz boost for the first time.

Interesting; hopefully I'll end up having the same experience. Thanks for that info!

Apparently my 3600 has been running the IF at 1,800 MHz with the Auto setting in the BIOS. Problem with that was the RAM is only stable at 1,733 MHz so it was running de-coupled. Set the IF to 1,733 MHz and would you look at that, memory latency dropped to 69.3ns from 78ns.

While I can't personally attest to this just yet (I'll test a bit on it later). From a Hardforum user in reply to my seemingly poorly binned 3600X:

"PBO is fully broken right now. Youre wasting your time with these dicussions until a resolution is released. Turn PBO off and use boost only. "

Yes you are right, did a quick test in CPU-Z bench, with PBO i got 1 thread 519p without it 521p, it does nothing, AMD could admit that, they just make Ryzen 3000 owners confused and desperate, regret the buy.

I had the same results, no change with PBO on or off. It'll get sorted out as BIOS updates and software updates come along. These are the prices you pay for adopting new things early, just a speed bump. Still faster than the setup I did for my friend with an 8086k @ 5.0GHz all core when the 3600x does 4.1GHz all core and 4.25GHz single. I'm still happy with it and am super glad to be rid of Intel and nvidia.

Just built my PC yesterday with an MSI pre-MAX Tomahawk board. Against all odds the PC booted first try. Now the issue is with high idle voltage and subsequently high idle temp.

Ryzen Master, CPU-Z, HWMONITOR all show 1.448 idle volt. My Windows 10 1903 is up to date and I also installed the latest 1.7.29 chipset driver with Ryzen Balanced plan selected.

* The only thing I touched in the bios is to set memory XMP
* The windows install is a carry over from my last build. Should fresh install fix it?
* I would have re-flashed the bios but wanna check if it's a windows/driver issue

I know this is a bit old but just saw this post I have my cpu at 1.18125 ish volt and 4200 and got a sweet score on cinebench r20 im using an ic thermal pad which I've used on my old cpu but i'm going to switch to arctic mx4 cause I do not like the temps but check this out.

I know this is a bit old but just saw this post I have my cpu at 1.18125 ish volt and 4200 and got a sweet score on cinebench r20 im using an ic thermal pad which I've used on my old cpu but i'm going to switch to arctic mx4 cause I do not like the temps but check this out.
Holy frequency Batman! 5000pts with 1.18v, but is it stable stable? Please share your secret.

Seems that new bioses will improve performance of Zen2 chips allowing less voltage that reduce power draw and improve thermals that in turn allow higher sustainable all-core-clocks.
