And goldchain said several times he got better results with PBO turned off, but I dont know what it is, or why it would be better on OR off. ... Stock voltage was around 1.35 all core for me which caused the chip to slow down as temps reached 85c. I have trying really hard to get stable at 4.6ghz even on just on set of cores and its not happening even at crazy voltages. For a better experience, please enable JavaScript in your browser before proceeding. The VCore the SOC protections are there to shut the system down if the voltage goes too high, like if … Messing around yesterday, either my chip is a complete dog or I'm really screwing things up. Oic it is in "red" now. Anyone using a 3900x with a corsair h110i gt? Maybe with a better RAD or something I could do better. I just noticed that temps were idling at 70ish and immediately hitting the 95c thermal limit on load. I am talking identical setup other than the CPU 3600 vs 3900x in the Asus setup. I jotted down some numbers from a thread on techpowerup and a video by jayztwocents (YouTube). The best I could do was 4.35 GHz on the good chiplet and 4.25 GHz on the bad chiplet. So where can i find the values on the right i circled? Also, the whole post is about CPU but you said it's running hot … A new BIOS is not going to fix voltage requirements and heat. You should get the beta bios and dig into the per CCX overclocking. Sure 50-60 idle is kinda too much, but then it shouldn't stay at 4.2GHz while idling as well. 8028 on the Cina - not to bad, Ran AVX2 Beta in CPUz as a stress, seems good for about an hour. for example, there are 2 VDDGs in the bios, and neither of them are labelled CLDO. Hopefully, I'll be able to mess around with it tonight. Quick look to Google suggests 1.325 has been reported by AMD as a "Safe" but I cannot find this on any AMD articles or really any kind of review / overclock review. jayztwocents mentioned this. So, I went back in and removed the -.1 offset from core voltage. For gamers and creators alike, that’s mission-critical performance built to help you win. Looks like you win the silicon lottery this time. Memory type? I couldn't complete a CB20 run at 4.3 all core at even 1.3875v. is that realy a big ask? It's a lot easier using 1004 bios and doing it in bios. Ryzen 3xxx CPUs tend to run at veery high voltage even on idle. At max load leading up to that point I never breached 75c temperatures. **********/d0J9RQNk/4-3-OC-2.png, Ryzen 5 3600X All Core 4300Mhz Ryzen Master-Voltage are normal as you would expect, Ryzen 5 3600X All Core 4300Mhz Motherboard BIOS-Voltage are off when set through BIOS, https://www.reddit.com/r/Amd/comments/cbls9g/the_final_word_on_idle_voltages_for_3rd_gen_ryzen/, https://forums.guru3d.com/threads/finally-fixed-my-ryzen-temps-voltage.430402/, (You must log in or sign up to reply here. I think i looked in every menu and submenu. So I had a look in bios again. https://hardforum.com/threads/manually-overclocking-ryzen-2-3900x.1986951/. Thought I was in the all clear as it didn't power off immediately like it usually does if I push the clocks too high on lower voltages, but then the familiar happens and it powers down. I am running the latest ABBA bios for the MEG Ace. I would say too high. It appears my chip hits some kind of power usage threshold and shits the bed. is this some sort of secret? Next scroll down to “CPU Voltage” and change the value from the default to 1.3V. A software like HWINFO64 can help you with this. I dont know why this would be... but its either that or im blind. BCLK? I watched this one the day I ordered the board. Based on the new voltage info which I cannot actively keep cool enough to use I have stabilized at 4.525 all core OC on 1.36v - Anything over 1.40v starts to strain my loop and I hit 80c on the CPU. Wait, I don't get it. Ignore what RM says are the preferred cores. Thats all i changed, and that voltage seems wayyyy to high compared to what im seeing above. Hey all, i had to join this forum just so i could take part in this discussion, and hopefully get some help from you guys as you certainly know more about this than me! (note: Apologies: I see that the same message was posted twice (revised in this post), but I'm unable to delete or even edit the original post for some reason) I first reported my issue in Aug 16, 2019. Similar, but not a match so I didn't want to dick around with what I wasn't sure of. the bios apply wrong voltages to numerous things, it was asus he mentioned also. You should really undervolt it. i was able to run CBr20 and score 9533 at 4.1 all cores, 1.375v. Again, im not shooting for the stars but id also like things to be correct. Thanks for the link. One thing I like about my board is it has an AMD overclocking voltage setting that lets me dial it up and down by .1mv so I can do 1.34 or 1.35 and it kind helps me keep it on the lower end of what I think is acceptable for voltage. That is one sick chip btw. You try just setting the multi / voltage in the bios? The onboard firmware in the CPU controls that, not the power plan. example, nowhere in those images does it say how or where the changes in BIOS were made, what voltage mode was used, etc. I was running into major issues with PBO on. One Chiplet I can OC to around 4.3x and the other 4.5x. What board are you running, ram and settings? unfortunately the manual is useless. The heat and voltage required is too high. Quick Side Note : All of my overclocking is done in the BIOS, I really do not like the Ryzen overclocking tools. Setting the Bar for High Performance. Personally, I have my chip set to -1.0V so the 3900x never has more than 1.4V fed to it (I did the same on the 3700x; l actually had this CPU with a 1.250V undervolt and it did just as good as stock. thanks again for the input. It doesnt explain them at all. That means you most definitely have at least one CCX that can go higher in multi. What the power plans do change, however, is whether or not the CPU downclocks at idle or jumps straight to power-gated sleep (cc6 power state). In my case and with my specific MOBO (Asus C6H - x370) the different Ryzen CPUs I had (3600x, 3700x and now 3900x) behaved in the same way: - High voltage at idle up to 1.5V - (Thus) 'high' idle temps: around 37-45ºC AMD specifies 3200MHz as memory clock on the Ryzen 9 3900X. Looks like you got GoldChain shitlet and he got your good chiplet. I bump up one more multi setting. I dialed things back to 1.35, and clocked the chiplets separately. Played a few hours of CoD too. The Ryzen 9 3900XT, 7 3800XT and 5 3600XT processors have 12, eight and six cores, respectively. I bet you have even more performance left on the table. I am not sure that I am doing it right... but its working ok so far. I manually dialed in 1.3125 volts. If LLC is set too high, this spike in voltage as the CPU goes to idle could be reaching harmful levels. I feel a little stupid now. Ryzen 9; 3900x heat, voltage and frequency issues. Keep an eye on the temps. Fixing the frequency caps the single core performance to a lower level than peak boost will reach on auto. Just like the stupid tools from the Phenom days they do not seem to do exactly what I want. You are close to that 8K geeze! So the take away is manual fixed ratio overclocking really is a pointless endeavor on the 3900X. Jul 12, 2019 But I have tried to use Ryzen master, and its idea of stable is a joke. The two PBO test sets are used to provide a reasonable high-power comparison point, to gauge the "dangerousness" of voltage under-reporting at stock. Increasing GFX voltage to 1.3V did nothing, and did not change the voltage readings at all. I tried making the same adjustments in bios that i did in RM, plus a few addtional tweaks to the only other settings i could find. Kidding aside, try OCing individual cores in Ryzen Master to see which one is limiting you plus figure out which CCD you can OC more. I tried some overclocking with Ryzen Master. So I am very confused in terms of a "Safe" all core voltage for my 3900x. Check the CPU core voltage and the RPM of the pump. thanks for the reply pendragon. I played around with RM a bit. Oh are you running the beta agesa? ... which should be enough to ensure that the system won’t crash and that temperatures won’t get too high. 1.35 range ideal. Or do you exclusively OC in RM? 1.4 max. Im sure that NOT changing any of the other settings is hurting me. Chip still wouldnt get stable over 4.6 with 1.4+ volts. My board was over-volting my 3900x by quite a bit. I do not all core overclock (except testing) so my cpu volts are left as standard or with a small offset which does improve your clockspeeds. It maybe just one limiting core or CCD. EDIT 7/10/19 @ 15:48 UTC: these comments are true of any 3rd Gen Ryzen. I then ran Prime 95 at those settings and the computer rebooted after about 5 minutes. Like way too high. So I have no idea what its doing to determine that. https://i. Can confirm SMT totally not worth dickin with. Now, I can get the sh!tlet to 4.3 and the chiplet to 4.425 and pass Cinebench. I wrote down all the other #s i could see in the screenshots above, and went looking for them in bios, and i cant find them. Maybe I'll make it 16-16-16-32. it doesnt explain any of this... i looked. Heres a screen shot. I set voltage to 1.325 in Ryzen Master. The more cores, though, the less worthwhile all-core OCs get, because the same all-core voltage for e.g. Dropping the voltage down hurts overall peak performance. No, the 3900X is not being overvolted. I shouldn't need the voltage I'm using for the RAM. I guess pushing things too much is an asus thing. Unfortunately it's about as useful as the manual where it just says that settings exist. What am I doing wrong? Never out of the 60s. PCB revision? Voltage offset is your friend. and then all the ns #s.... where do i get that info? Yeah, I was going to say.. thermally limited, 1.5v too much. PBO doesn't do anything on an all core overclock afaik but it does make it easier to raise the limiters. When I went into bios I didn't find anything that matched. Anything higher will not finish a CB20 run. However, with the sh!tlet at 4.3, and the chiplet from 4.35 up to 4.425, I get the same score 7655. Why don’t you read through this forum thread and see if it can answer your question? Thanks for the info and your time. Then I have 1 core that shits the bed. They struggle with giving people work units, and if you split your CPU into multiple smaller workers, you will experience very high temperatures, too high to run 24/7. 1. Here is what I observed with a really good case airflow and Noctua D15 on my 3950X and 3900X alike. Check your voltage if you run high temps on idle!!! i dont understand why someone wont just say this setting is that setting, that setting is this setting. We're just discussing the 3900X for the sake of simplicity, here. I changed RAM timings to 16-16-16-32 and still got horrible performance. 1.003 not 1.004 yet. I am going to do some SMT testing and core preference testing tonight, ill let you know how that turns out too. 50-100mhz of one core on a 3900x is (Edit: I had the math wrong forgot to account for 12 cores, lol) 0.125-0.25% of its processing power, just to throw that out there. Still seems crappy compared to the other chips mentioned in this thread. It may not display this or other websites correctly. It wont finish Cinabench R20 with Ryzen master stable. I found it to be completely wrong. I think the memory controller on mine is weak. On asrock idle voltages are miles better than asus in windows. It's B Die spec'd at 4000 19-19-19-39 at 1.35v. ). My averages are always 1.4v. Im just curious, I also noticed my board was over volting the piss out of my CLDO VDDG, MEM VTT, VDDCR SOC and CLDO VDDP, I had to manually set them into spec and as soon as I did more headroom opened up. I’d keep it in the 1.3x v range. All core, a 3900x will struggle to reach 4.2ghz. Someone else mentioned that 16-15-15-32 is an odd timing. By supplying the processor with less voltage we’re reducing the amount of heat generated in use. With 4650 MHz as the maximum (and always very short) value reached, the Ryzen 9 3900X is still just below the 4.7 GHz mark, but still surprisingly high. I might try some chilled loop OC'ing a later this year. You must log in or register to reply here. The most interesting part of these results, however, are the scores with a negative voltage offset: the Godlike board was stable with an offset as low as -0.1V using the 3900X… I wrote a massive reply but decided to deleted it. You are using an out of date browser. But this only works if all other cores clock in the direction of 3.6 GHz. Pushed the voltage up incrementally to 1.35 to see if I could push 4.5GHz on all cores. Gen. CPU, I advise to go the 'voltage offset' route. When I get home from work ill try and post some tips and just some general rules I followed when trying to push my chip. Not shown, i also disabled PBO. The Ryzen 9 3900XT managed an all-core overclock frequency of 4.3GHz at just 1,325V, which is reasonable but not outside the realms of something I've achieved with my 3900X … There, Broke 8k lol. AMD Ryzen 3900X I use reaches a boost frequency of 4,500 MHz and usually operates around 4.20 - 4.25 GHz on all [or most] cores. so how am i to know which to change? I also tried the DRAM calculator tool, but that lead me nowhere as pretty much everything is was asking me to input, i didnt know. I just got an interesting email back from AMD. Discussion in 'Processors and motherboards AMD' started by CPC_RedDawn, Dec 30, 2019. ASRock X370 Taichi. Asus board will idle in 1.4v mostly, yes it does dip to sub 1v but lot less than asrock board. Reply TJ Hooker 19 June 2020 19:00 JavaScript is disabled. Also, temps are completely fine at all of these settings. Which got me looking at voltages and the BIOS had the CPU at 1.45ish for god knows what reason. They must not be named exactly the same in bios vs RM. Looks like you're running stock power limits?? Hey all, long time lurker, rare poster here. As it stands yer minimum achievable core multi is 44.25. I guess I though Ryzen Master was taking care of this, but I guess not, because I got further. The starred/preferred ccx were my weakest, smh. Then they run hot. Raising my voltage just brings it to that envelope quicker, doesn't really seem to help with the OC much. Low 50s on idle. I think there is something to be explored with the way that the BIOS is telling the OS what the fastest core is, and the preferred power preferences which the setting name escapes me right now. i will load up 1 of the above screenshots on my phone and look in the bios, but it seems most of what im seeing above is ram timings? 0 Kudos Mine is nowhere close to that. I haven't tried to go so 'low' on voltage on the 3900x yet. You're supposed to watch temps under heavy load, not while idling. I entered what was availble from the G.Skill site, but the calculator wanted more values. The yellow curve shows the beat of the fastest nucleus in the comparison. Memory rank? If your CPU is OC, it may also be good to reset it to factory settings. Ryzen 3900X with a Corsair H100i rad and MX-4 in between. Under heavy load the 3900X can run at 1.1v with vdrop which is a great CPU. a 12 core 3900x pushes many more amps through the CPU than a 6 core 3600 would, assuming the same silicon quality. AMD’s high-performance x86 Core “Zen 2” architecture enables 3rd Gen Ryzen Processors like the AMD Ryzen 9 3900X to deliver the highest single-thread and multi-thread performances for mainstream desktop processors.
