AMD Ryzen 2000 Overclocking Thread

VPII · Apr 23, 2018

Taken that AMD released their Zen+ core Ryzen 2700X, 2700, 2600X and 2600 on 19 April 2018 and I was lucky enough to pick up mine on 20 April 2018 I thought it be good to start a thread to see what we can get out of these new CPUs.

Unfortunately the Asus X470 motherboards are missing in action, clearly visible even when checking Amazon and Newegg in the USA so I had to settle to start with a X370 board. I wasn't all that happy but I figured that being about 50 days without a computer is enough and I'll bite the bullet and get an X370 board now and sell it when the X470 boards from Asus arrive.

Firstly I must give a big thank you to @Wootware for actually flashing the bios of the motherboard for me to have it working with the Ryzen 2700X I purchased. I also got word today that my X470 board should be available on 2 May 2018....only a few more days.

So now for the results..... Please understand that the cpu only ran for one startup at stock to see that it worked. I went straight to 4.2ghz all core on the second startup without an issue except that I overshot with the vcore at 1.35v. Yup 1.35 should have been about 1.2 to 1.25 but I'll explain going forward. I tried with some help from @Gouhan all the way from afar to see how high I could go and 4.3ghz was no problem at 1.4vcore but with some advise I set LLC to 4 and dropped the vcore ultimately ending at 1.33vcore stable all benches. My max clock going higher ended at 4.35ghz with 1.4vcore which is where I decided to stop..... I can try to go higher and will most likely get higher but I do not want to kill a good cpu as I've done with my old 1090T.

All my cinebench and Geekbench 3 runs was at 4.35ghz.

Cinebench 2003- not great but not to bad when looking at other results on Hwbot against clocks - my memory is okay but I need to still learn how to tweak properly

Cinebench 11.5

Cinebench 15R

Geekbench 3 - I found that after spending a bit of money running it in 64bit helps

PC Mark 7 - Yup not the greatest but still the 2nd best score for an 8 core chip...... but maybe because very few people run it....he he he

I though Ill do one 3d run so I went with Time Spy..... not the greatest but not too bad I would say

Great result man. Its good to see Ryzen+ samples all hitting around the same Overclocks. Out of curiosity what cooler were you using?

VPII · Apr 24, 2018

Cooler Master Liquid ML240L is the cooler I'm using....

This is actually an exceptional CPU.
So far I'm not aware of any other CPU that clocks like this one. Low voltage, high clock.

VPII · Apr 24, 2018

I'll maybe try some Dry Ice over the long weekend to see what I can get out of this cpu. Still not X470 board but the board I have seem to do pretty well.

Not the chipset, but the board. ROG Crosshair is very strong

Nice clocks so far! What RAM are you using and what is the speed and timings?

VPII · Apr 26, 2018

The memory I use is G.Skill F4-3200C14D-16GTZR TridentZ RGB and I am running it at 3485mhz CL14-13-13-32 1T. I can possibly fine tune the memory a little more but thus far not too bad for X370 motherboard.

VPII · Apr 27, 2018

Done some Dry Ice testing this morning. I got the Asus Crosshair VII Hero but for some odd reason it won't run my CPU at the same speed with the same vcore, so I decided to do the DICE run with the X370 board.

Right now I seem to have found my 24/7 overclock. I tested with Aida64 stress test and I'll be honest it heats up the cpu more than any other tests. I tested with Prime 95 small FFT which failed after 10 minutes.... not failed but hanged with no response. In my discussions with @Gouhan I found that doing a 15 minute run or more with Aida64 stress test is enough, which I believe to be true as it shows within a minute if there is any instability. In comparison 15+ minutes into Aida the cpu was sitting at 83.8c highest where as Prime95 was at 78.3c

But because Prime95 hanged I decided to drop the speed down to 42.5 x 100 which is still pretty good using only 1.268vcore.

Ebrahim Ali · May 4, 2018

Wow that really is an impressive chip!

Mo Facta · May 6, 2018

Not in the same league but I was able to get a stable and cool overclock on the 2200G to 3.85GHz without an aftermarket cooler. Stock all the way. Max temp after P95 stress test for 30 min was 68C.

Could have gone much higher with even an AIO. And easy peasy lemon squeezy.

I am somewhat brand agnostic but no doubt AMD is killing it for enthusiasts.

Cheers

Apparently running RAM with tightened up timings can give you as big or if not bigger gains than straight overclocking the cpu

I've never tried the performance enhancement settings in the bios of the CHVII hero. Well I tried it this morning and I was pleasantly surprised to the point where I lowered some of my vcore settings in other saved bios settings.

Well I've overclocked my 2700X since I got it, at first on an Asus ROG Strix X370-F Gaming which unfortunately do not have the performance enhancements you get with the Asus Crosshair VII Hero, so my overclocked stayed and I was happy that I was sitting with 4.216ghz using only 1.268vcore. SOC etc I've manually set to the stock 1.05v and all seemed good. SO this morning I decided I wanted to see what the cpu can do when I load default bios settings and change the performance enhancement from Auto to 1 or 2 as 3 did not work before. But I decided to give 3 a go to see what I get. I was amazed when I ran Stilt's CPO test - see first screenshot below.

Performance enhancer 3
CPU Speed 41.75 x 100 = 4160mhz all cores
Hwinfo Vcore: 1.28v
Cpuz Vcore: 1.21v which is the closest to actual reading with a multimeter

I then went on to try out performance enhancer 4. Now understand this, I have clocked my cpu up to 4.36ghz using 1.45vcore and I was able to do so with even less vcore for running benchmarks, more so when I was using the X370 board. With this board I'm able to run the cpu at 4.3ghz using only 1.4vcore set in bios with LLC set to 5. But this is what I got from performance enhancer 4.

CPU Speed 43 x 100 = 4.29ghz
Hwinfo vcore: 1.369v
CPUz Vcore: 1.352v
Actual reading with multimeter in picture below: 1.32vcore

So the Crosshair seems really impressive! Would I still manage with the X470 Strix if I did not want such hectic OC'ing? Your X370 results were still great.

Another question, how do the PCIe lanes get distributed if I want to use an NVME SSD? This review says that the GPU will be at 8x speed instead of 16x if the top slot is used.

VPII · May 10, 2018

From what I gathered, when using the top slot your pci-e lane will fall back to 8x speed but if you use the bottom one it will remain at 16x which is what I'm doing at present.

The cpu really runs well and does not need high vcore for 4.2ghz.

This weekend I'll give the Asus Crosshair VII Hero a run with dry ice as I believe I may be able to hit 5ghz.

-Gifted- · May 10, 2018

I just picked up a 2700x this afternoon and dropped it into my crosshair vi, which previously ran a 1800x since launch. I had the 1800x set at 3.9 all core with a low voltage. The 2700x I just dropped in auto but I’m running. Big custom loop.
Updated hw monitor and Ryzen master and instantly it was running 4.1 on all cores just with precision boost just on desktop and only 30oC... I played far cry 5 for a couple of hours and left hw monitor on. When I finished I was surprised that hw monitor reported a max core clock as 4512mhz on all cores, and max temp of 60oC.

Tbh looks like with custom loop I might leave everything stock as no need to overlcock with those boosts. If I leave it at stock it throttles right down at idle to save power.

I’ll have to investigate further. But so far.... impressed. - my memory overclocked straight to 3400mhz too first time.

Hi Guys
I need some opinions from the guys who are more experienced with Ryzen than I am.
I have a R5 2600 on a Asus Prime X370 Pro and 16gb of Corsair Vengeance LPX DDR4 3000 C16 .
I built the system on Friday and started overclocking late Saturday night.In the BIOS I set CPU and SOC LLC to 4 ,maxed out voltage and current capability of each and set a multiplier of 40 ,tested than 41 and tested again and finally 42 and tested.It failed to run Cinebench all the way at 4,2ghz and as I was upping the voltage to stabalize it I noticed that Vcore showed what I had set in the BIOS ,SVI2 TFN showed a constant 1.150v and VDDCR CPU would show like 0.10v above Vcore.

So while I had set 1.3875v in the Bios VDDCR CPU reported 1.4875. Setting a lower LLC brought it down but still I was seeing high values for VDDCR.
The temps where fine (78 to 85) but I decided to back off and go down to 4,1ghz at 1,3675v LLC4 with VDDCR CPU showing 1.4675 peak during prime 95 and cinebench r15.

What voltage value should I take as the actual or closest to actual from Vcore ,VDDCR CPU , and SVI2 TFN ?
What voltage can I run my chip at wich will be safe for a 24/7 oc? Finally when using offset voltage mode how do I determine my offset?

Gouhan · Jun 4, 2018

Don't use offset then, just key in the voltage and also disable SVID.
1.3v should* be fine for 4.1GHz perhaps even 1.25V
I'd not set LLC when using Dynamic VID.
You need to know what the CPU can tolerate or rather what it needs to run at your desired clock frequency. Do this manually first, then you can set auto and use a negative offset if it's more than what you need (You would have discovered the right value using manual vCore/ CPU Voltage setting) positive if you need stability.

I'd honestly not bother running over 1.25v. The heat and power increase disproportionately to the clock and as a result you're losing a lot of the power you're putting into the CPU.
Make a long story short 1.25v would be my max for 24/7 but others seem to be ok with 1.3v

VPII · Jul 21, 2018

I finally got my system to run with a full pot of LN2 last night. I managed 5.53ghz but did not push any higher, that will be for tonight. I was pleased to see that the system behaved properly. Also noticed the speed shown with CPUz in the screenshot is lower. Probably c-states but I'll change it when I try again later today. Still some tweaks and fine tuning on memory needed.

But here are my results.

Hi guys. I know the title says that this is for 2000 series chips, however I have a 1700 and this should still work for 2000 series chips as well.

So I recently bought a convertible laptop with an i5 8250u and came across CPU under-volting in order to save power and reduce temps. This then lead to a tool (Throttlestop) that basically allows you intercept Windows and control the CPU clock states as you see fit... and amazingly this results in quite a noticeable increase in battery life.

Any how, I wondered if this would be possible on my Ryzen 1700 desktop so I began reading up and came across this tutorial RyZen Pstate Overclocking, method, calculation and Calculator

This method basically allows you to create custom power states for your CPU with frequency and voltage settings. The main benefits of this is that Ryzen XFR still functions, meaning that your processor can down-clock frequency and voltage when idle AND also boost frequency beyond what you set as the maximum all core frequency!

Previously I has set my overclock using the multiplier and voltage settings, knowing that my chip is happiest at 3.8GHz @ 1.30625v... so I basically modified the P0 power state with the settings based on the HEX values stated in the link and that was it. I was amazed to see my CPU frequency jump to as much as 4.5GHz in task manager for single threaded loads.

Further interesting point is that if XFR finds further 'free power' it boosts all core frequency further... So when running CR15, windows reports my CPU at 3.83GHz! Crazy.

This option for custom power states was only introduced with the newer BIOS versions for my board, however this almost sounds too good to be true. Has anybody else come across this? Are there any foreseeable downsides?

Afaik first gen Ryzen does not support XFR?

The AMD Zen and Ryzen 7 Review: A Deep Dive on 1800X, 1700X and 1700

"All the CPUs are multiplier unlocked, allowing users to go overclocking when paired with the X370 or B350 chipset. At this point we’re unsure what the upper limit is for the multiplier. We have been told that all CPUs will also support XFR, whereby the CPU automatically adjusts the frequency rather than the OS based on P-states, but the CPUs with ‘X’ in the name allow the CPU to essentially overclock over the turbo frequency. XFR stands for ‘eXtended Frequency Range’, and indicates that the CPU will automatically overclock itself if it has sufficient thermal and power headroom."

Star_22 · Sep 18, 2018

Thanks I read sometime ago the differences between 1st and 2nd gen Ryzen and got confused with the terms.

Going back to that article shared some further insight. My 1700 is 3GHz base frequency and 3.7GHz with turbo, which aligns to the 'new' base frequency of 3.8GHz and 4.5GHz boost frequency with the modified P0 state, confirmed by task manager.

Further point of interest is that XFR bumps the multiplier by 0.25x which also aligns with the 3.83GHz that Windows task manager is reporting whereas I set the 'base speed' at 3.8GHz
