However, with the sh!tlet at 4.3, and the chiplet from 4.35 up to 4.425, I get the same score 7655. it doesnt explain any of this... i looked. Next scroll down to “CPU Voltage” and change the value from the default to 1.3V. 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. ... Stock voltage was around 1.35 all core for me which caused the chip to slow down as temps reached 85c. I haven't tried to go so 'low' on voltage on the 3900x yet. Or do you exclusively OC in RM? The more cores, though, the less worthwhile all-core OCs get, because the same all-core voltage for e.g. Anything higher will not finish a CB20 run. 1. All core, a 3900x will struggle to reach 4.2ghz. I think the memory controller on mine is weak. so how am i to know which to change? The yellow curve shows the beat of the fastest nucleus in the comparison. But this only works if all other cores clock in the direction of 3.6 GHz. 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 might try some chilled loop OC'ing a later this year. So where can i find the values on the right i circled? 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. Ignore what RM says are the preferred cores. for example, there are 2 VDDGs in the bios, and neither of them are labelled CLDO. ASRock X370 Taichi. 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. Oic it is in "red" now. My averages are always 1.4v. Ryzen 3900X with a Corsair H100i rad and MX-4 in between. 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? So I have no idea what its doing to determine that. I set voltage to 1.325 in Ryzen Master. Not shown, i also disabled PBO. 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. Then they run hot. By supplying the processor with less voltage we’re reducing the amount of heat generated in use. I’d keep it in the 1.3x v range. My board was over-volting my 3900x by quite a bit. It appears my chip hits some kind of power usage threshold and shits the bed. I am talking identical setup other than the CPU 3600 vs 3900x in the Asus setup. 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. You must log in or register to reply here. i was able to run CBr20 and score 9533 at 4.1 all cores, 1.375v. Still seems crappy compared to the other chips mentioned in this thread. For a better experience, please enable JavaScript in your browser before proceeding. Chip still wouldnt get stable over 4.6 with 1.4+ volts. Discussion in 'Processors and motherboards AMD' started by CPC_RedDawn, Dec 30, 2019. At max load leading up to that point I never breached 75c temperatures. I dont know why this would be... but its either that or im blind. Thanks for the link. It's a lot easier using 1004 bios and doing it in bios. I tried some overclocking with Ryzen Master. But I have tried to use Ryzen master, and its idea of stable is a joke. Again, im not shooting for the stars but id also like things to be correct. unfortunately the manual is useless. So the take away is manual fixed ratio overclocking really is a pointless endeavor on the 3900X. Maybe with a better RAD or something I could do better. Thanks for the info and your time. 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. I am going to do some SMT testing and core preference testing tonight, ill let you know how that turns out too. https://i. What board are you running, ram and settings? Ryzen 9; 3900x heat, voltage and frequency issues. Mine is nowhere close to that. BCLK? 1.003 not 1.004 yet. Thats all i changed, and that voltage seems wayyyy to high compared to what im seeing above. A new BIOS is not going to fix voltage requirements and heat. thanks for the reply pendragon. No, the 3900X is not being overvolted. If your CPU is OC, it may also be good to reset it to factory settings. The VCore the SOC protections are there to shut the system down if the voltage goes too high, like if … The Ryzen 9 3900XT, 7 3800XT and 5 3600XT processors have 12, eight and six cores, respectively. Which got me looking at voltages and the BIOS had the CPU at 1.45ish for god knows what reason. I shouldn't need the voltage I'm using for the RAM. If LLC is set too high, this spike in voltage as the CPU goes to idle could be reaching harmful levels. I watched this one the day I ordered the board. 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. Heres a screen shot. I bet you have even more performance left on the table. Looks like you got GoldChain shitlet and he got your good chiplet. https://hardforum.com/threads/manually-overclocking-ryzen-2-3900x.1986951/. Dropping the voltage down hurts overall peak performance. Ryzen 3xxx CPUs tend to run at veery high voltage even on idle. example, nowhere in those images does it say how or where the changes in BIOS were made, what voltage mode was used, etc. **********/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. EDIT 7/10/19 @ 15:48 UTC: these comments are true of any 3rd Gen Ryzen. Here is what I observed with a really good case airflow and Noctua D15 on my 3950X and 3900X alike. 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 then ran Prime 95 at those settings and the computer rebooted after about 5 minutes. Can confirm SMT totally not worth dickin with. and then all the ns #s.... where do i get that info? It may not display this or other websites correctly. Increasing GFX voltage to 1.3V did nothing, and did not change the voltage readings at all. Played a few hours of CoD too. I dialed things back to 1.35, and clocked the chiplets separately. Quick Side Note : All of my overclocking is done in the BIOS, I really do not like the Ryzen overclocking tools. There, Broke 8k lol. The onboard firmware in the CPU controls that, not the power plan. What am I doing wrong? You should get the beta bios and dig into the per CCX overclocking. That is one sick chip btw. I just noticed that temps were idling at 70ish and immediately hitting the 95c thermal limit on load. ). 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. For gamers and creators alike, that’s mission-critical performance built to help you win. The best I could do was 4.35 GHz on the good chiplet and 4.25 GHz on the bad chiplet. AMD specifies 3200MHz as memory clock on the Ryzen 9 3900X. Jul 12, 2019 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! Fixing the frequency caps the single core performance to a lower level than peak boost will reach on auto. Also, temps are completely fine at all of these settings. When I went into bios I didn't find anything that matched. I bump up one more multi setting. You are using an out of date browser. 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 … It maybe just one limiting core or CCD. Asus board will idle in 1.4v mostly, yes it does dip to sub 1v but lot less than asrock board. JavaScript is disabled. Why don’t you read through this forum thread and see if it can answer your question? 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. Reply TJ Hooker 19 June 2020 19:00 You're supposed to watch temps under heavy load, not while idling. Low 50s on idle. Also, the whole post is about CPU but you said it's running hot … You should really undervolt it. I wrote a massive reply but decided to deleted it. So I had a look in bios again. It doesnt explain them at all. I couldn't complete a CB20 run at 4.3 all core at even 1.3875v. I entered what was availble from the G.Skill site, but the calculator wanted more values. Voltage offset is your friend. We're just discussing the 3900X for the sake of simplicity, here. (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.
