I'm using a B350 motherboard on my 2700x (upgraded from a 1700x) is it better to run it on stock with XFR or all cores at 4.1GHz 1.34v. I can get it stable at 4150mhz but I decided to just leave it at 4.1GHz and the voltage is not that high

 

I consider it a waste to run a 2700X on a B350 motherboards. All B350 motherboards lack adequate VRM support and that is why you are only stable to 4.1 GHZ on all cores. I am stable to 4.25 GHZ on all cores on my MSI X470 Gaming M7 AC motherboard. It is about 4th best on vrm support of X470 boards. Bested by Asus ROG CH7, Gigabyte X470 Gaming 7, and Asrock X470 Taichi.

 

honestly for me in most cases stock works better... I have a custom loop and the chip overclocks itself to right at 4ghz on all cores under heaviest loads... and all core moderate loads it hits 4.1.... normal loads like gaming and such I see 4.2 to 4.25 ghz common... so it really depends on what you are doing... on all core loads an overclock on all cores is better in general this chip takes care of itself pretty well.

 

I've only tested it in dota 2 and it only boosts upto 4GHz at stock. I wonder maybe because I'm only using a B350 motherboard

 

we in this boys! woot woot!

 

wondering if you will get better clocks on that than I am on my B350... so far I see peaks routinely hitting 4.35 on up to two cores at a time.... but I can't OC past 4.25 on all cores at once

 

SiliconLottery states only 4.2GHz or so for highest bin (i.e. passing Prime95). https://siliconlottery.com/collections/pinnacleridge
* 41x multi at 1.375V
* 41.5x multi at 1.4V
* 42x multi at 1.425V

With Ryzen Master set to 1.45V on the best 4 cores I am able to hit 43.25x multi , 1.4V for 43x multi on best 4 cores.

I think that these CPUs aren't worth multiplier overclocking. The gains are mostly from memory and cache improvements AFAIK. BCLK seems to be the way to go, I will try to get a definitive answer.

PBO+ XFR2 seems to have it hit around 41-42x multi on my chip when all cores are loaded and it is in a X370 board.

For people that don't overclock it's a serious boost over Ryzen 1st gen. My first gen Ryzen is around 1750 Cinebench @ 3.9GHz - 4 GHz, this gets close to 1800 out of the box without messing with PBO so it's likely hovering around 4050 MHz.
Luckily I didn't buy two chips, I think I'm going to get an i7-8700K if Z390 comes around with some decent boards.

Is your XFR2 on?

that silicon lottery bit is interesting... I hit mine with avx linepack for a few run and a few other stress tests at 4.25 @ 1.45v with no issues... board was getting warm a bit since I had LLC turned up enough to keep voltage level... but 4.2 was a breeze to get... I'll try it with prime 95 and see how that does... I usually use linepack with avx because it's pretty much as high as stress can get, but it's possible that on these prime 95 will find an issue I was otherwise unable to find

 

I enabled the OSD in MSI afterburner to check the clock speed and it's all over the place lol. I tried rocket league and it's ranging from 4000-4175mhz and it doesn't stay put (I saw it go as high as 4200 for just a split second) but usually stays around the 4050-4100 range. does that affect frame times seeing how clock speed changes all the time?

most of the games I've tried it's at 4000-4050mhz. I will try more

 

shouldn't have much affect on frame times over all.... of coarse generally speaking higher clocks is better for frame times.

 

I decided to stick to my 4.1ghz overclock. I’ve tried a few games and usually it boosts below 4100mhz and games like pubg it hovers around 3975-4000mhz. I’ll just keep it at 4.1ghz I think I’ll get a more consistent performance with this OC

 

and that's the thing with these 2700x's no two people will have the same experience... glad you found what works for you... I tried even a 4.25ghz OC and found that in many cases stock actually worked better lol... but then you saw my screen capture... and that game was one of the worst on the cpu of all I play... It's called The Crew, and it used to keep my FX running @ 75% usage on most map locations with Miami pushing it in the 80's for some reason... but on Ryzen gen 2 it's a walk in the park. Dirt 4 barely uses the cpu and then usually only two cores for whatever reason, but those two cores will boost to 4.35 ghz many times in game.

On another note, I was just playing with a 4.2ghz OC and testing with prime 95 for a bit this time... had to adjust my LLC levels a bit, but as near as I can tell setting just over 1.4v in bios with a fair bit of LLC to keep vcore from dropping below 1.39 and it so far hasn't dropped cores or froze... at first I had hard freeze but voltage dropped to 1.35 lol.... without LLC turned on the vdroop on this board is ridicules. That silicon lottery post by AlphaC has got me wondering... I had kinda assumed based on what I saw from others that 4.2ghz was mediocrity at its finest... but now it looks to be a bit rare maybe? Just don't know if I really want to leave it running for too terribly long... at 4.2 these chips can really pull some power already hit 180 watts peak power draw according to HWiNFO64

 

I'm not sure how large the sample size is also.

https://www.hardware.fr/articles/974-7/overclocking-pratique.html
Prime95 stable on 8 cores @ 4.3GHz , 1.35V unless I'm reading it wrong

Quasarzone OC scaling https://quasarzone.co.kr/bbs/board.php?bo_table=qc_qsz&wr_id=152517

 

Using PE1 on my CH VII i usually stick around 4075Mhz in BF1 which IMO is right where the cutoff is before voltages start to get nutty. PE3 boosts up to 4150, but it was only stable for like 30 minutes in RealBench before it crashed. My chip may be above average since it held 4.15Ghz @ 1.3v for 30 minutes, but i don't really see how a 4.2Ghz all core overclock would even be worth my time to test for stability.

 

When we will get a decent uefi 42x will be something easy at 1.32+V underload,but right now LLC,temps are f...and that huge amount of power draw when stress with IBT or p95, you won't see too often in daily usage.

 

I had gotten the upgrade itch and decided to sell my Ryzen 1700 and upgrade to a 2700X. Still using my Asus Prime X370 Pro tough. It's cooled with a Noctua NH-D15.

I'm not sure if it's normal, but I'm getting really high temps when running Prime95 small fft.
I've set the 2700X to a fixed speed of 4Ghz @ 1,2875v in the bios with LLC3. This results in a vcore of 1,256v while stressed. Temps are 73C measured at Tdie while stressing.

Isn't this a bit high? I ran my 1700 at 3,8Ghz with 1,325v with LLC3 and it never got over 67C in Prime95 and OCCT.

I've tried remounting the cooler, reapply the paste (Gellid GC Extreme). But I'm getting the same temps over and over.

I know I can let it run at stock, but I like to tinker and wanted to compare it a bit with my 1700. What temps are you guys with fixed speeds getting? Is the 2700X really this much hotter?

dont know about how normal it is, but I've noticed these seem to run a bit hotter than the 1700 I had did... now keep in mind I'm on a custom loop, but I haven't seen it hit 70's that at that low of a clock/voltage... more like mid 50's when that low.

 

Yeah the cpu is a bit hotter than the first ryzen, which is kind of weird if you asked me using the same voltage and mhz the temps are higher.

 

What kind of memory clocks are you guys able to hit? I decided to sell my 1700 and pick up a 2700x this past weekend. I'm using my old ASRock x370 Gaming Professional board and hitting a hard wall of 3466. I can boot 3600 and run a few benchmarks but prime95 will instantly fail. Even with loose timings and 1.2v SoC I have no luck. I can run 3466 14-14-14-34 all day though so I'm not sure if I'm having problems with my board or my IMC isn't that great.

 

i really start to like this XFR/PB on this cpu.

I have everything on auto except scalar=10x and 300/300/300 PB
i get 41.25x for example on most app all cores on P95 HIGH FFTS i get 41 and 40x on small ffts he detects the load if is a high power draw (small fft he will downclock to 40x) as cores start passing this small ffts the ones still on them raise a little bit more and more on clock speed till they pass and go back to 41x. In other apps that only uses a few cores they use up to 43.50x. 4-6cores 42-42.50x avg which is better than a fix all around multi at all times.

I have everything on auto including my llc the only thing i dont like is the high vcore on idle. It can shoot as high as 1.55v in this mobo. I can do 41.25x at 1.37v but im missing the whole ordeal of XFR/PB which is where is at with this cpu.

This and with the PPM Panel tweaks i previously used on my ryzen 1700/1800x this cpu shines all on auto

This is a comparison

ciao, what's your cooler? same settings and mb in the blend test i touch the 74 in tdie... I have a h100i v2 +2 vardar@2000rpm. it seems to me too much. i tried to reapply the thermal paste but nothing change..
However i agree with you, the sweet spot seems to be just @def with ram pushed and the PBO active ..

 

Hey guys, I don't post much but I read alot. Most of you guys are way ahead of me knowledge wise so I appreciate the reading material. I just ordered 2700X with a ASRock 470x Fatality board and some G. Skill Flare 14-14-14-34 / 3200 kit 16GB. But I'm going to love this coming from my ole 8350 and my 980ti classy can stretch now a bit. Keep the info coming ...lol Thanks all ... Peace, Splash

 

I'll join in on this since I don't have the others anymore.

Just to add another....

Upgraded to full AMD system: https://valid.x86.fr/p2g2xk

 

https://valid.x86.fr/rif8x3

Straight forward OC (42.225 multi) on all cores. Starting voltage set at 1.425v with LLC5, 1200% power. All C states off.
Still waiting for Asus Prime x470 pro and hopefully I could use my RAM to fullest, now stable only up to 3333MHz.

 

not bad at all... best I was able to muster was 4.25 on all cores stable... my highest cinebench score was 1938 @ 4.275ghz, wasn't stable though... Honestly even with an all core OC of 4.25 I lost performance in some games over stock because at stock it boosts 2 cores to 4.3-4.35ghz which is higher than I can OC to on all cores.... and since it boosts 4 cores to 4.2+ regularly I just went back to stock... my best passmark scores were at stock lol.. same for userbench... only programs that could use all 16 threads really benefited from the all core OC

 

Minotaurtoo: I'm running stock eventhough I have an Asus CH6H with 6004 BIOS, 2700x, EK AMD EVO Supremacy waterblock with 2-360 rads and 16G of Flare-X 3200 ram.

Like you, I was able to OC to 4.2 GHZ on all 8 cores but even with all of my cooling capacity, the temps rose significantly from stock.

Also, I get a solid 4GHZ all core OC at stock when stressing with decent scores, for example CB15 -1804-1809.

I had previously run a 1800x OC'd to 4 GHZ ( could push it a bit higher but was flaky) so I settled on that as a solid OC. This 2700x stock slightly outperforms the heavily OC'd 1800x.

I realize that this forum's mantra is "Overclock" and I respect that (I have a 5960x solidly at 4.4 and a 6700k solidly at 4.6) but my initial impression of the 2700x, after some cursory OC attempts, is that AMD has this cpu, at stock, pushed to nearly the limit but it did a MUCH better job of sustaining more of the 8 cores at higher clock speeds when stressed.


Good cooling helps.

 

In! 2700x, Asus prime x470, 16bg gskill trident z rgb running at 3200mhz

 

That stock cooler so nice. Can you give me the link for the memory trident Z RGB. Thanks

 

Do people worry about stock boost voltages, they hit over 1.5v?

I have set -0.075 offset, PE3, bclk 101, all core is around 4090, single core boost 4392, max V 1.481 and around 1.237 all core load voltage. Not sure its actually stress test stable however I have not had a single crash in my normal usage.

 

It's pretty normal, I wouldn't worry about it... it's AMD's way of ensuring stability on weakest cores when they boost to 4.35... if you are stable with the voltage offset though, there is no reason to not keep the voltage offset... might even result in better overall performance since the algorithm works based on temps and power usage.

 

Whoever's on hwbot should be beating my garbage scores for OCN's sake. Need to socket it into the X470 board to put up "real" results with BCLK. I had those for a baseline comparison.

I joined the club yesterday!!!! Love it. I can't get it to upload my cpu-z shot. Is it because I'm new maybe? I was going to join the Ryzen 7 first gen owners club last year but never got around to it I guess.

Edit: here's a link https://valid.x86.fr/wfjxfb

 

I just figured out how to make my R7 2700X CPU shut down due to CPU thermals (of all things).

8 threads or more in VirtualBox with SVM enabled , BOINC running 8 threads. 6 threads is fine , power remains under 100W and voltage under 1.35V-ish. CPU ~65°C for 6 threads.
Will have another try on X470 once I get better RAM for it.

I think Numberfields@home hammers it so hard that the virtualization breaks.

edit: I turned off PBO and temps only hit 60°C now

 

Is it just me or are the 2700x's temps really unstable? It'll occasionally spin up to 4.35ghz and 1.4+V when web browsing and the temps immediately kick up to nearly 70C in HWinfo (60C actually I think, with offset accounted for). It causes my fans to spin up to max. The 1700 I'm swapping out never had any issues like this and had relatively stable temps, or at the very least it was never in a situation where the temps jumped like 25C instantly.

 

Heh, yeah. I really want to rock the wraith prism because it looks cool. However there have been instances where i've seen the temps spike up to 82C (TDie). It wasn't even in prime or anything. I think i had wow open. Hopefully i get my FSP Windale 6 here shortly. Should prevent that from happening.
