What am I doing wrong? Sure 50-60 idle is kinda too much, but then it shouldn't stay at 4.2GHz while idling as well. You're supposed to watch temps under heavy load, not while idling. Quick Side Note : All of my overclocking is done in the BIOS, I really do not like the Ryzen overclocking tools. Check the CPU core voltage and the RPM of the pump. As it stands yer minimum achievable core multi is 44.25. I guess pushing things too much is an asus thing. 1.35 range ideal. My averages are always 1.4v. Under heavy load the 3900X can run at 1.1v with vdrop which is a great CPU. 8028 on the Cina - not to bad, Ran AVX2 Beta in CPUz as a stress, seems good for about an hour. 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. I jotted down some numbers from a thread on techpowerup and a video by jayztwocents (YouTube). So the take away is manual fixed ratio overclocking really is a pointless endeavor on the 3900X. for example, there are 2 VDDGs in the bios, and neither of them are labelled CLDO. ASRock X370 Taichi. Ryzen 3xxx CPUs tend to run at veery high voltage even on idle. You should really undervolt it. Maybe I'll make it 16-16-16-32. Someone else mentioned that 16-15-15-32 is an odd timing. I haven't tried to go so 'low' on voltage on the 3900x yet. What board are you running, ram and settings? Pushed the voltage up incrementally to 1.35 to see if I could push 4.5GHz on all cores. Wait, I don't get it. is that realy a big ask? I then ran Prime 95 at those settings and the computer rebooted after about 5 minutes. Like way too high. Increasing GFX voltage to 1.3V did nothing, and did not change the voltage readings at all. the bios apply wrong voltages to numerous things, it was asus he mentioned also. So I am very confused in terms of a "Safe" all core voltage for my 3900x. Next scroll down to “CPU Voltage” and change the value from the default to 1.3V. I set voltage to 1.325 in Ryzen Master. a 12 core 3900x pushes many more amps through the CPU than a 6 core 3600 would, assuming the same silicon quality. The Ryzen 9 3900XT, 7 3800XT and 5 3600XT processors have 12, eight and six cores, respectively. i was able to run CBr20 and score 9533 at 4.1 all cores, 1.375v. Also, the whole post is about CPU but you said it's running hot … https://i. However, with the sh!tlet at 4.3, and the chiplet from 4.35 up to 4.425, I get the same score 7655. Check your voltage if you run high temps on idle!!! You are close to that 8K geeze! Also, temps are completely fine at all of these settings. 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. I’d keep it in the 1.3x v range. Chip still wouldnt get stable over 4.6 with 1.4+ volts. Oh are you running the beta agesa? I entered what was availble from the G.Skill site, but the calculator wanted more values. Memory type? Still seems crappy compared to the other chips mentioned in this thread. You are using an out of date browser. You should get the beta bios and dig into the per CCX overclocking. so how am i to know which to change? Keep an eye on the temps. PCB revision? https://hardforum.com/threads/manually-overclocking-ryzen-2-3900x.1986951/. 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. I manually dialed in 1.3125 volts. So, I went back in and removed the -.1 offset from core voltage. Reply TJ Hooker 19 June 2020 19:00 Setting the Bar for High Performance. I am not sure that I am doing it right... but its working ok so far. 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. I would say too high. Anyone using a 3900x with a corsair h110i gt? Similar, but not a match so I didn't want to dick around with what I wasn't sure of. No, the 3900X is not being overvolted. Can confirm SMT totally not worth dickin with. I might try some chilled loop OC'ing a later this year. I think the memory controller on mine is weak. I guess I though Ryzen Master was taking care of this, but I guess not, because I got further. Discussion in 'Processors and motherboards AMD' started by CPC_RedDawn, Dec 30, 2019. Asus board will idle in 1.4v mostly, yes it does dip to sub 1v but lot less than asrock board. is this some sort of secret? ). Fixing the frequency caps the single core performance to a lower level than peak boost will reach on auto. I am going to do some SMT testing and core preference testing tonight, ill let you know how that turns out too. 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). Heres a screen shot. 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. So I have no idea what its doing to determine that. There, Broke 8k lol. Then I have 1 core that shits the bed. It appears my chip hits some kind of power usage threshold and shits the bed. 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! Thanks for the link. 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. One Chiplet I can OC to around 4.3x and the other 4.5x. thanks again for the input. I shouldn't need the voltage I'm using for the RAM. Here is what I observed with a really good case airflow and Noctua D15 on my 3950X and 3900X alike. JavaScript is disabled. Mine is nowhere close to that. 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. 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. You try just setting the multi / voltage in the bios? it doesnt explain any of this... i looked. Ignore what RM says are the preferred cores. When I went into bios I didn't find anything that matched. i dont understand why someone wont just say this setting is that setting, that setting is this setting. Memory rank? 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 … and then all the ns #s.... where do i get that info? It maybe just one limiting core or CCD. Oic it is in "red" now. Im sure that NOT changing any of the other settings is hurting me. Yeah, I was going to say.. thermally limited, 1.5v too much. 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. Gen. CPU, I advise to go the 'voltage offset' route. I feel a little stupid now. It's B Die spec'd at 4000 19-19-19-39 at 1.35v. 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. Ryzen 3900X with a Corsair H100i rad and MX-4 in between. I wrote a massive reply but decided to deleted it. 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. Anything higher will not finish a CB20 run. That means you most definitely have at least one CCX that can go higher in multi. 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. 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. 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. So I had a look in bios again. I bump up one more multi setting. We're just discussing the 3900X for the sake of simplicity, here. All core, a 3900x will struggle to reach 4.2ghz. 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. AMD specifies 3200MHz as memory clock on the Ryzen 9 3900X. **********/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. 1.003 not 1.004 yet. 1. example, nowhere in those images does it say how or where the changes in BIOS were made, what voltage mode was used, etc. (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. Looks like you got GoldChain shitlet and he got your good chiplet. Ryzen 9; 3900x heat, voltage and frequency issues. PBO doesn't do anything on an all core overclock afaik but it does make it easier to raise the limiters. The heat and voltage required is too high. The onboard firmware in the CPU controls that, not the power plan. So where can i find the values on the right i circled? unfortunately the manual is useless. 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. 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? If LLC is set too high, this spike in voltage as the CPU goes to idle could be reaching harmful levels. That is one sick chip btw. Again, im not shooting for the stars but id also like things to be correct. 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… Then they run hot. Never out of the 60s. Messing around yesterday, either my chip is a complete dog or I'm really screwing things up. A software like HWINFO64 can help you with this. 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. On asrock idle voltages are miles better than asus in windows. But this only works if all other cores clock in the direction of 3.6 GHz. Maybe with a better RAD or something I could do better. I watched this one the day I ordered the board. 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 Raising my voltage just brings it to that envelope quicker, doesn't really seem to help with the OC much. Now, I can get the sh!tlet to 4.3 and the chiplet to 4.425 and pass Cinebench. For a better experience, please enable JavaScript in your browser before proceeding. I bet you have even more performance left on the table. Or do you exclusively OC in RM? I am running the latest ABBA bios for the MEG Ace. Hey all, long time lurker, rare poster here. Not shown, i also disabled PBO. The VCore the SOC protections are there to shut the system down if the voltage goes too high, like if … They must not be named exactly the same in bios vs RM. 0 Kudos I just got an interesting email back from AMD. ... which should be enough to ensure that the system won’t crash and that temperatures won’t get too high. I changed RAM timings to 16-16-16-32 and still got horrible performance. Hopefully, I'll be able to mess around with it tonight. The best I could do was 4.35 GHz on the good chiplet and 4.25 GHz on the bad chiplet. By supplying the processor with less voltage we’re reducing the amount of heat generated in use. At max load leading up to that point I never breached 75c temperatures. 1.4 max. I was running into major issues with PBO on. Looks like you win the silicon lottery this time. Dropping the voltage down hurts overall peak performance. I found it to be completely wrong. Thats all i changed, and that voltage seems wayyyy to high compared to what im seeing above. Looks like you're running stock power limits?? A new BIOS is not going to fix voltage requirements and heat. It doesnt explain them at all. You must log in or register to reply here.
