Tried to oc my ryzen 5 2600x to 4.1 ghz on all cores but sort of failed just by changing multiplier to 41, changing vcore, loadline calibration, setting vddr cpu and soc current capability to 120-130%,changing cpu,soc power phase control to extreme, it failed in ibt (setting vcore and the power phase control,soc,cpu current capability to more normal values and 4ghz it ran ibt fine)

I was hoping for 4.2ghz on all cores at max 1.4 volt.

I run flare x 3200 mhz cl 14 at 2400mhz since they are not on the qvl list and i havn't gotten them to run 3200mhz cl 14

I have ordered Corsair Vengeance LPX DDR4-3000 C15 BK DC - 16GB only 12x 3200mhz ram on the qvl list Min 87x 3000mhz on the qvl list 4x 2933mhz ram on the qvl list (LOL) and i sold my 3200mhz cl 14 ram so i didn't have to pay anything to get new ram, because of the high number of 300mhz rma on the qvl list i bought that.

I can imagine my ram won't let me run 4.1ghz 100% stable but also that it shouldn't make a difference since it must be some setting for my cpu, i mean it boost fine at stock aut vcore and cpu on aut so the bios desides how high it goes in ghz, in theory it should be able to run at 4.20 ghz on all cores, just with higher vcore and more heat, right?

What am i doing wrong?

Mine tops out at 4.1 GHz with 1.4 volt all core overclock. The only changes I'm required to make is manually setting the multiplier to 41, and a override of 1.4 volt. DDR4 is running at it's rated 3200 MHz with a tiny bit of tightening of timings over stock timings(16-18-18-18-36<15-17-17-17-35.)

Edit: Sorry for the short post. I was still at work, and didn't want to stay any longer than necessary.

Bad silicone lottery? Reading/watching around the internet, he best of Ryzen 2000 overclock runs at 4.2 GHz, with average 4.1 GHz all cores overclock. Perhaps you just got a bad silicone.

I was under the impression that overclocking the X series rarely makes sense since XFR always runs at the best possible frequency? What i have seen people doing instead is try and undervolt using negative offset in order to reduce thermal load allowing the CPU to boost for longer and / or higher.

Also from my experience overclocking my 2700 non-X 4.2GHz is pretty optimistic, 4.1GHz is more in line what you can expect at 1.4V. Another thing to note is not to overclock the CPU and RAM at the same time. First find max of one then of another and then see what is the max stable combined. For example my CPU at 1.4V runs at 4.13 GHz with ram at stock and my RAM can go up to 3333MHz when CPU at stock, however for both overclocked I had to settle for CPU @ 4.05 GHz and RAM @ 3200MHz.

Finally for overclocking the ram, did you use the Ryzen calulator?

shouldnt flare x run 3200mhz cl14 with xmp 2.0 in bios? like literally one click - done?

I run 4ghz all core 1.3V, bcoz it was ezpz no hassle 10 minute stable overclock tyvm.

my ram doesn't run 3200mhz cl 14

i have used ryzen calculator

what ghz does the ryzen 5 2600x run at at diffrence cores, i mean it would definitely run 3.6ghz on all cores but mabye not more then 4.2ghz on 2-4 core?

I concur. XFR actually is set modestly on some motherboards as in my case, I use MSI B450M Mortar, and the XFR is actually pegged very very conservatively. Setting on auto, I got your standard Ryzen 2700X speeds, peaks out at 4.0 GHz all cores. On setting XFR to enabled gave me a one core boost up to 4.6 GHz since my cooling allows it and and average of 4.1 GHz all cores... Mind you temp shoots up like mad and the CPUID Hwmonitor shows crazy core voltages.

Frankly, if you want to play with overclocking today, you go for Intel. It's not a commendation per se towards Intel, is just that AMD clearly optimized Ryzens out the gate.

There is no way that's possible without bclk overclock. And even then I would question it.

I'd find out the lowest voltage you can get then test xfr as you gradually bring up the voltage.
Overclocking the CPU is less important on Ryzen compared to overclocking the memory.
Sure it helps... But Ryzen is limited.
All I could get my 1600 to was 3990mhz.
It's completely unstable at 4ghz but perfectly fine at 3990mhz.
Good news is going from 2400mhz memory speed to 3000mhz is noticeable and amazing.

Many will do 4.2, especially an X model zen+ but it isnt guaranteed. I can tell you ime taking any Ryzen past 4ghz is exponentially more taxing on them. All of them. The heat and voltage go wayy up there if they can do it at all. Anything past 4 is approaching the absolute limit.

Also keep in mind its one thing to be able to bench 4.2... but another to run it daily. A lot of people will hit that but it doesnt mean that it can fully handle it. Most people talking about them will try for a max OC initially but sometimes thats just people talking and playing around. Doesnt mean everyone can run rock-stable 4.2 overclocks. Just means it is possible sometimes. My chip will do it. I dont think its all that common for people to run them that way though.

Nothing wrong with 4ghz all core. To me thats the point of diminishing returns for a stiff hand OC. Thats where I run my vanilla 2600. Runs great there. Very cool and efficient for what is on my end no percievable performance difference. And I have a really good one thatll run a stable 4.2 @ well under 1.4v. 1.4v will take me all the way to 4.3, even if only just barely.

The thing is... the difference in actual usage is pretty much nothing. Just a whole lot more heat. Benchable but otherwise not relevant for most people. Ryzen doesnt scale like that. 200mhz across all cores isnt significant enough to matter in anything but heavily threaded workloads.

Honestly since you have an x chip you might as well take advantage of its best features and skip the all-core. You can do that just the same with the vanilla version. For gaming that single core boost counts for a lot more than constantly pumping every core. Ryzen is good at disttibuting the boost to where its needed, to the point where an all-core can lose out to it even with the lower base clocks.

Does your mobo support pbo? You can get your overall clocks higher that way.

As mentioned before, Ryzen is generally cashed-out out of the box. There is an architecture bound clock speed wall and x chips are configured to give you pretty much all you can get.

Must be truly bad luck if 2600X can't go further. I'm running my 2600 non-X at 4.15GHz 1.4V without problems.

Ran it with less than 1.40v's to the CPU as shown but I've actually gotten 4350 from it, couldn't get the validation but managed a screenie.

Thing with these chips are thermals as mentioned, they can only take so much and sometimes voltage doesn't do anything but make them run even hotter than before.
Both results I have aren't suitable for everyday use by any means, more to see what potential this chip has as an OC'ing chip.

Dropped it right back to 3.7 once done and dropped CPU voltage back to 1.21v's because thermals are good with that voltage used and it seems to like it that way so.... I just go with it.
Note that 4.1 for most seems to be the average lid for everyday use, if you can get that with good temps UNDER LOAD, not at idle you'll be fine.

Im @4335mhz on my 2700X 1.47v, and 3550mhz on my Trident Z 3600mhz cl18.
Hoping for 5ghz and 4000 ram when Ryzen 3xxx is released!
I give you less then 6 months before the chip seriously starts to degrade.

Most Ryzens shoud'nt go any higher then 1.375V for long term 24/7 usage.

I have left my 2700x at stock with PBO level 2. Called it a day. That 2% increase in a all core overclock with the extra power thus heat is'nt worth it. XFR/PBO does already a good job.

Im going for 4.2 ghz, my limit is my cpu cooler scythe mugen 5 with 2 fans, it's already at 76c at 4.1 ghz,1.3875 volt and around 1200 rpm on both fans. (max rpm is under 1300 rpm)

Had it at 4ghz and 1.38750 volt and bumped it to 4.1ghz nothing else changed (stable) so i think i could go for 4.2ghz if i had a different cooler for the worst case senario, even when you max oc a cpu not to use all of the power .

Like a car that has enough power so you never have to push it to it's limit in everyday use but still have more than enough power on the highway, if for some reason you need more power you have it.

I have before had a noctua nh-d15, would it be this cpu cooler for 4.2ghz, also had the big phanteks PH-TC14PE (noisy compared to noctua) Be Quiet Dark Rock Pro 4 (never had one) or something else for 4.2ghz?

At low rpm max (700) i don't hear the fans on my cpu cooler, even in gaming i don't hear anything, my rtx 2060 strix is running at mabye 25% fan speed, perfect for silent freaks (me)

So what is max voltage for a ryzen 2600x for 24/7 use?

Stock speed it does go above 1.400 volt

Your temps for that are too high it seems, if you are already seeing 76c with no load applied @ 4.1GHz it's just getting too hot to run once a load is applied the way it is now.

I'll also say the board you have, while it's not bad isn't the best for such either.
The Prime line of Asus boards isn't as robust as the true ROG line is and you may even be running into VRM thermal issues with it. The Prime line isn't known for crazy OC'ing, even the Strix lineup has been called "Watered down ROG" before and that seems to be true about it. The board you have isn't junk by any means, it's just when you buy a cheaper line/model of board that's what you get in terms of what it is and what you get from it.

That's why when I went shopping I bought the best of the ASRock lineup that was available for this build and at least I don't have to worry alot about the guts of it being up to task.

You can however place a small fan in the board's VRM area and see what difference it makes, that may well show a difference in what you get from it. I checked the cooler you have, it's actually a better cooler than mine so you shoudn't have any real issues with cooling as long as all else is right.

In the end you may just have a dud for a chip, that's how it goes sometimes and if so you gotta deal with it for what it is or just grab another one.

no no it's of course with load, prime 95 small fft.

I don't know lower vcore limt at 4ghz and i don't know max ghz at 1.3875 volt or under 1.400 volt.

I do see some say max safe vcore for ryzen 2000 is as low as 1.36volt (last answer)

What's the actual 'safe' voltage for 24/7 usage with 2600(x)?
