Got the Following Setup:
Asus Tuf Gaming Plus Wifi
Noctua NH-D15 Cooler
Patriot Viper 3733 17-19-19-39
My Cpu wont boost beyond 4050Mhz (4041,81 in CPU-Z) in any Mode, I tried Default / PBO and Auto Overclocking.
It dosnt matter if I run Multi Core Stress/Bench or Single Core, all the time it boosts to 4050Mhz All Core / Single Core.
I would be happy if it would boost to 4.2Ghz when only 1 Core is on Load, but I cant get it past 4.05Ghz.
Board Temps/VRM always Cold.
Cpu Temp always below Single 50°C Multi 64°C
Not sure what to do, already tried alot of stuff in the Bios, then Cmos Clear, Load Default, try stuff again, etc. Its always stuck on 4050Mhz
Good grief. I do not know how users expect to get help by denigrating the helper! John.
EDIT: Your specifications say your processor should boost to 4200 MHz. I recommend that you open an AMD Online Support Ticket.
I'm experiencing exactly the same problem with my Ryzen 3600. CPU boost is stucked on 4.05 GHz (Single core) no matter what. Interestingly I have Asus motherboard as well (TUF B50M-gaming). I hope some bios update will fix this issue, I really like this CPU.
I have heard that some Asus boards are still struggeling with Zen 2. I am running a 3600 on an "old" X370 from MSI with a crappy beta BIOS and it boosts beyond 4.2 with Auto OC enabled.
This is the answer. ASUS x570 owners, ASUS boards in general really, aren't likely to see proper boost clocks with Zen 2. It might be a few other x570 boards from other vendors too but I dont really follow them.
ASUS bios team just slacked with this launch. It will improve tho.
Steve From HWU did an in depth video that shows its more than just ASUS. Lots of different boards are having trouble hitting their boost frequencies, and im going to guess NONE of them are actually maintaining those boosts for any reasonable time.
Managed to "fix" the Issue by installing a fresh Windows 10, it now boosts to 4.18 max. by default but even with auto oc or pbo fixed to +75mhz it wont boost beyond the 4.18ghz. I wrote both to Asus and Amd Support, both dont seem to care much. Amd offerd that I send the CPU in, which im not interested in and Asus Support stopped caring after I told them new install fixed the Issue with 4.05 stuck. Not interested looking into the Pbo/Auto Oc problem it seems.
Would be nice to get beyon 4.18ghz when only using 1 Core but i can live with it.
I cannot find anything with that name or anything simular. Any Idea what to look for ? CPU-Z shows Bus Speed 99.80 but I dont see any Bios option to change it to 100.
99.80 in CPU-Z is correct, Spread Spectrum is disabled (which mostly is the case by default anyway, you should find it somewhere in your BIOS CPU settings). If you can confirm (e.g. with HWInfo) that none of your cores boost to ~4200 MHz but only ~4175 MHz, then I still suspect your BIOS. You could set your BCLK in your BIOS to 100 (Auto by default) but I don't think this will improve things whatsoever. Again, ASUS is not the best choice at the moment for Zen 2, but this will improve with upcoming BIOS updates.
Beyond a clean install of Windows 10 (which I hope it included the lastest AMD Chipset Drivers from the website), you could try disable PBO, XFR and any Auto-Overclocking option you can find in BIOS (either Asus or AMD ones), leave voltage on auto or default, turn off any vcore offset you could have set. Next go into Windows and download 1. HWINFO Portable (https://www.hwinfo.com/download/) from thier official page, and 2. Cinebench R20. Run HWINFO - ONLY SENSORS (avoid using the beta version), you will find MIN, AVG and MAX columns, now launch Cinebench R20 (single and 12 core tests) and run the bench, HWINFO will keep track of the highest frecuency your CPU reach on the MAX column, please let us know what the readings are.
Hi delavoy, first of all, Im not an expert nor similar, I can see that on hwinfo it looks as top speed was ~4125MHz (which is not bad), not the 4.2GHz it should have reached according to what AMD website. Also are you running Windows 8 (Cinebench screenshot)? Since your cooler should be way better than stock one, I believe CPU temps are not the limiting factor (I can't confirm that since theres no hwinfo pic with temps). Even though Windows 8 may not the best OS to use with Ryzen 3xxx CPU I don't thnk is hurting your build either. The only thing I can imagine is that maybe, just maybe, your CPU boost behavior (without manual tunning) may need more power than what your motherboard "feels confortable" to deliver. HWIinfo shows that to reach 4125MHz your CPU needs 1.450v. On my Ryzen 5 3600 (before I disable PB to have silence again), I've saw voltage go as high as 1.468v on hwinfo, and frecuency to ~4.199MHz (With my stock cooler, frecuency drops down really fast anyways, and temps goes up way higher than I feel confortable with - another reason why I disable PBO. Also when gaming on an RTX 2070, when playing SOTR or BFV I didn't noticed any frame drops for 60Hz my monitor can handle. Even if I disable vsync, both games shows AVG FPS above ~90, never saw FPS drop below ~75, ad this is playing at the highest image settings).
Im not defending AMD with the next, but since this is a new fabrication node (7nm) for Zen2, theres probably a lot of things that can be tuned (on the software side of things), maybe a new BIOS, Windows update, and/or AMD Chipset Drivers will eventually fix most, if not all CPU boosting issues. I honestly didn't have much time to test and overclock my CPU yet, but if I found something new I will try to post it here with pics. The first thing I wana test when I have time, is to see how much voltage do I need to get to stable 4.1GHz.
For now 4.2GHz with my stock cooler is a NO. So I will try 4.1GHz and see if I can get near that with around 1.350~1.380v
I use Windows 10 Home 1903. Another one is Cinebench Error. If i use MSI Game Npost my CPU is stable in 4200 MHz with 1.36V Vcore and 1.1V Soc.
I dont understand why my CPU will not achive in Auto boost the 4200 MHz. It stuck At 4100 MHz. PBO doesnt really Help.
I found the same, PBO and AMD "AutoOverclocking" does not really help at all, the only thing it did in my case was raise vcore voltage even higher and temps with it. Thats why I disable PBO, and AMD AutoOverclocking as soon as i got my Ryzen 5 3600 (on my Gigabyte B450 gaming X those are split in 3 dif options that needs to be turned off).
Also as an update, maybe some of you saw it already, maybe didn't, read, and see this two:
As I mentioned before, it is Motherboard / BIOS related and will most likely be fixed with upcoming BIOS versions. As you can also see, no ASUS board in this video hits the max boost frequency at the moment. Don't gasp, be patient
Ok, so I got back home from work, and I run Cinebench Single Core Test (see the image for details).
Only PB is enable on BIOS, so no PBO, XFR, Auto-overcloking, nothing like that (everything else is on Auto, no offset volatge,nothing at all).
I found two things:
1. Clock was around what I wrote earlier, 4192.3MHz, bouncing around the best cores as expected for a Ryzen 3xxx CPU (thats almost 4.2GHz).
2. Voltage was lower than I remember, between 1.388 and 1.425volts (maybe something to do with the new AGESA 1003ABB and/or the chipset drivers).
So yeah, perhaps the issues reported have something to do with motherboards, something that may prevent CPU from reaching higher clocks.
Once again, my mobo is a Gigabyte B450 Gaming X (which is nothing special, but for the strange VRM configuration which Im still trying to figure out.
I have my ryzen 5 3600 operating up to 4.1GHz all cores at 1.325v Vcore. It is fully stable.
In my case i was not able to reach 4.2GHz unless i changed de Vcore up high.
Also i want to mention that it was imposible to reach a stable clock higher than 4.00 with ryzen Master, i just had to do it with the override mode of the motherboard
My PC specs:
cpu: Ryzen 5 3600
gpu: RX 590
ram: 16gb DDR4 3200 cl16
motherboard: MSI B450A-PRO (agesa 188.8.131.52.ABBA)
Yes, it will go up to 4.125 @1.325v only if i push it, gaming ultra at 1080 and recording/streaming at 1080 60fps
If im in the desktop or internet Ryzen master shows that the Average Core Voltage is betwen 0.3-0.7 also the speed drops down to +-300Mhz
Idle: 39-40ºC (+-104ºF)
Max: 81ºC (+-177ºF)
Room temperature: 20-25ºC (68-77ºF)
Cpu cooler: Thermaltake contac 9
Case: Nox Hummer zx with (2 frontal 120mm fans, 1 back 120mm fan)
Soon I will put two more 120mm fans on top and change the thermal paste to Noctua NT-H1
I know, but my case is not prepaired to have fans over 120mm
must be a real puny box, i use the monster Cooler Master HAF 932 which has 230mm fans
