One Chiplet I can OC to around 4.3x and the other 4.5x. So I have no idea what its doing to determine that. I just got an interesting email back from AMD. so how am i to know which to change? For a better experience, please enable JavaScript in your browser before proceeding. So I had a look in bios again. So the take away is manual fixed ratio overclocking really is a pointless endeavor on the 3900X. Im sure that NOT changing any of the other settings is hurting me. The onboard firmware in the CPU controls that, not the power plan. 8028 on the Cina - not to bad, Ran AVX2 Beta in CPUz as a stress, seems good for about an hour. 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. Ryzen 3900X with a Corsair H100i rad and MX-4 in between. As it stands yer minimum achievable core multi is 44.25. The heat and voltage required is too high. 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 … Maybe with a better RAD or something I could do better. I think the memory controller on mine is weak. Still seems crappy compared to the other chips mentioned in this thread. It's a lot easier using 1004 bios and doing it in bios. 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? Similar, but not a match so I didn't want to dick around with what I wasn't sure of. Under heavy load the 3900X can run at 1.1v with vdrop which is a great CPU. I manually dialed in 1.3125 volts. Then I have 1 core that shits the bed. You are using an out of date browser. Dropping the voltage down hurts overall peak performance. The yellow curve shows the beat of the fastest nucleus in the comparison. Gen. CPU, I advise to go the 'voltage offset' route. So where can i find the values on the right i circled? 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. When I went into bios I didn't find anything that matched. BCLK? At max load leading up to that point I never breached 75c temperatures. Now, I can get the sh!tlet to 4.3 and the chiplet to 4.425 and pass Cinebench. My averages are always 1.4v. So, I went back in and removed the -.1 offset from core voltage. Thanks for the info and your time. It doesnt explain them at all. 1. ... which should be enough to ensure that the system won’t crash and that temperatures won’t get too high. Just like the stupid tools from the Phenom days they do not seem to do exactly what I want. However, with the sh!tlet at 4.3, and the chiplet from 4.35 up to 4.425, I get the same score 7655. I couldn't complete a CB20 run at 4.3 all core at even 1.3875v. Increasing GFX voltage to 1.3V did nothing, and did not change the voltage readings at all. Looks like you got GoldChain shitlet and he got your good chiplet. I feel a little stupid now. I jotted down some numbers from a thread on techpowerup and a video by jayztwocents (YouTube). i was able to run CBr20 and score 9533 at 4.1 all cores, 1.375v. 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 think i looked in every menu and submenu. I dialed things back to 1.35, and clocked the chiplets separately. Oh are you running the beta agesa? thanks again for the input. Also, temps are completely fine at all of these settings. I shouldn't need the voltage I'm using for the RAM. Pushed the voltage up incrementally to 1.35 to see if I could push 4.5GHz on all cores. https://hardforum.com/threads/manually-overclocking-ryzen-2-3900x.1986951/. Ignore what RM says are the preferred cores. a 12 core 3900x pushes many more amps through the CPU than a 6 core 3600 would, assuming the same silicon quality. The starred/preferred ccx were my weakest, smh. If LLC is set too high, this spike in voltage as the CPU goes to idle could be reaching harmful levels. 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). A new BIOS is not going to fix voltage requirements and heat. The more cores, though, the less worthwhile all-core OCs get, because the same all-core voltage for e.g. It may not display this or other websites correctly. It appears my chip hits some kind of power usage threshold and shits the bed. What am I doing wrong? I am not sure that I am doing it right... but its working ok so far. 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. 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. Or do you exclusively OC in RM? Can confirm SMT totally not worth dickin with. You should get the beta bios and dig into the per CCX overclocking. I entered what was availble from the G.Skill site, but the calculator wanted more values. 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. for example, there are 2 VDDGs in the bios, and neither of them are labelled CLDO. 1.4 max. I am running the latest ABBA bios for the MEG Ace. What board are you running, ram and settings? I played around with RM a bit. But this only works if all other cores clock in the direction of 3.6 GHz. You are close to that 8K geeze! It maybe just one limiting core or CCD. Wait, I don't get it. Played a few hours of CoD too. I guess pushing things too much is an asus thing. I just noticed that temps were idling at 70ish and immediately hitting the 95c thermal limit on load. 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. Next scroll down to “CPU Voltage” and change the value from the default to 1.3V. I found it to be completely wrong. Hey all, long time lurker, rare poster here. Check the CPU core voltage and the RPM of the pump. 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. Discussion in 'Processors and motherboards AMD' started by CPC_RedDawn, Dec 30, 2019. That is one sick chip btw. 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. Setting the Bar for High Performance. A software like HWINFO64 can help you with this. I bump up one more multi setting. 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. 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! 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. Looks like you're running stock power limits?? I dont know why this would be... but its either that or im blind. (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. I haven't tried to go so 'low' on voltage on the 3900x yet. Fixing the frequency caps the single core performance to a lower level than peak boost will reach on auto. I am talking identical setup other than the CPU 3600 vs 3900x in the Asus setup. Like way too high. On asrock idle voltages are miles better than asus in windows. 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. The Ryzen 9 3900XT, 7 3800XT and 5 3600XT processors have 12, eight and six cores, respectively. AMD specifies 3200MHz as memory clock on the Ryzen 9 3900X. ASRock X370 Taichi. 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. thanks for the reply pendragon. EDIT 7/10/19 @ 15:48 UTC: these comments are true of any 3rd Gen Ryzen. 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 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. Mine is nowhere close to that. Looks like you win the silicon lottery this time. Jul 12, 2019 Oic it is in "red" now. 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. There, Broke 8k lol. 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. Keep an eye on the temps. 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. But I have tried to use Ryzen master, and its idea of stable is a joke. Low 50s on idle. You must log in or register to reply here. I then ran Prime 95 at those settings and the computer rebooted after about 5 minutes. 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… You try just setting the multi / voltage in the bios? Which got me looking at voltages and the BIOS had the CPU at 1.45ish for god knows what reason. 1.003 not 1.004 yet. No, the 3900X is not being overvolted. Check your voltage if you run high temps on idle!!! I am going to do some SMT testing and core preference testing tonight, ill let you know how that turns out too. 0 Kudos ). jayztwocents mentioned this. 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 guess I though Ryzen Master was taking care of this, but I guess not, because I got further. Someone else mentioned that 16-15-15-32 is an odd timing. JavaScript is disabled. 1.35 range ideal. 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. Why don’t you read through this forum thread and see if it can answer your question? **********/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. Yeah, I was going to say.. thermally limited, 1.5v too much. So I am very confused in terms of a "Safe" all core voltage for my 3900x. By supplying the processor with less voltage we’re reducing the amount of heat generated in use. Sure 50-60 idle is kinda too much, but then it shouldn't stay at 4.2GHz while idling as well. I watched this one the day I ordered the board. is that realy a big ask? Ryzen 3xxx CPUs tend to run at veery high voltage even on idle. I might try some chilled loop OC'ing a later this year. Again, im not shooting for the stars but id also like things to be correct. Chip still wouldnt get stable over 4.6 with 1.4+ volts. I was running into major issues with PBO on. Quick Side Note : All of my overclocking is done in the BIOS, I really do not like the Ryzen overclocking tools. Ryzen 9; 3900x heat, voltage and frequency issues. PCB revision? 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. it doesnt explain any of this... i looked. We're just discussing the 3900X for the sake of simplicity, here. I tried some overclocking with Ryzen Master. Memory type? https://i. the bios apply wrong voltages to numerous things, it was asus he mentioned also. Not shown, i also disabled PBO. You're supposed to watch temps under heavy load, not while idling. 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. Also, the whole post is about CPU but you said it's running hot … It wont finish Cinabench R20 with Ryzen master stable. Memory rank? That means you most definitely have at least one CCX that can go higher in multi. They must not be named exactly the same in bios vs RM. I wrote a massive reply but decided to deleted it. All core, a 3900x will struggle to reach 4.2ghz. It's B Die spec'd at 4000 19-19-19-39 at 1.35v. Messing around yesterday, either my chip is a complete dog or I'm really screwing things up. Voltage offset is your friend. The best I could do was 4.35 GHz on the good chiplet and 4.25 GHz on the bad chiplet. You should really undervolt it. PBO doesn't do anything on an all core overclock afaik but it does make it easier to raise the limiters. Never out of the 60s. unfortunately the manual is useless. I set voltage to 1.325 in Ryzen Master. I changed RAM timings to 16-16-16-32 and still got horrible performance. Heres a screen shot. I bet you have even more performance left on the table. I’d keep it in the 1.3x v range. Thanks for the link. ... Stock voltage was around 1.35 all core for me which caused the chip to slow down as temps reached 85c. The VCore the SOC protections are there to shut the system down if the voltage goes too high, like if … and then all the ns #s.... where do i get that info? My board was over-volting my 3900x by quite a bit. Anyone using a 3900x with a corsair h110i gt? Then they run hot. Here is what I observed with a really good case airflow and Noctua D15 on my 3950X and 3900X alike. If your CPU is OC, it may also be good to reset it to factory settings. is this some sort of secret? Reply TJ Hooker 19 June 2020 19:00 Unfortunately it's about as useful as the manual where it just says that settings exist. Anything higher will not finish a CB20 run. Hopefully, I'll be able to mess around with it tonight. example, nowhere in those images does it say how or where the changes in BIOS were made, what voltage mode was used, etc. Maybe I'll make it 16-16-16-32. Asus board will idle in 1.4v mostly, yes it does dip to sub 1v but lot less than asrock board. Raising my voltage just brings it to that envelope quicker, doesn't really seem to help with the OC much. For gamers and creators alike, that’s mission-critical performance built to help you win. i dont understand why someone wont just say this setting is that setting, that setting is this setting.
