Just like the stupid tools from the Phenom days they do not seem to do exactly what I want. https://i. It's a lot easier using 1004 bios and doing it in bios. That is one sick chip btw. The VCore the SOC protections are there to shut the system down if the voltage goes too high, like if … Check the CPU core voltage and the RPM of the pump. It appears my chip hits some kind of power usage threshold and shits the bed. I just noticed that temps were idling at 70ish and immediately hitting the 95c thermal limit on load. Like way too high. 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. I was running into major issues with PBO on. For a better experience, please enable JavaScript in your browser before proceeding. 1. BCLK? However, with the sh!tlet at 4.3, and the chiplet from 4.35 up to 4.425, I get the same score 7655. If your CPU is OC, it may also be good to reset it to factory settings. One Chiplet I can OC to around 4.3x and the other 4.5x. I played around with RM a bit. The yellow curve shows the beat of the fastest nucleus in the comparison. What am I doing wrong? and then all the ns #s.... where do i get that info? ASRock X370 Taichi. Increasing GFX voltage to 1.3V did nothing, and did not change the voltage readings at all. They must not be named exactly the same in bios vs RM. Here is what I observed with a really good case airflow and Noctua D15 on my 3950X and 3900X alike. Thanks for the link. a 12 core 3900x pushes many more amps through the CPU than a 6 core 3600 would, assuming the same silicon quality. When I went into bios I didn't find anything that matched. So I have no idea what its doing to determine that. As it stands yer minimum achievable core multi is 44.25. 1.4 max. I am going to do some SMT testing and core preference testing tonight, ill let you know how that turns out too. Looks like you're running stock power limits?? Unfortunately it's about as useful as the manual where it just says that settings exist. So where can i find the values on the right i circled? 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. Keep an eye on the temps. the bios apply wrong voltages to numerous things, it was asus he mentioned also. For gamers and creators alike, that’s mission-critical performance built to help you win. Wait, I don't get it. I dialed things back to 1.35, and clocked the chiplets separately. You are using an out of date browser. https://hardforum.com/threads/manually-overclocking-ryzen-2-3900x.1986951/. Hey all, long time lurker, rare poster here. Gen. CPU, I advise to go the 'voltage offset' route. I watched this one the day I ordered the board. So the take away is manual fixed ratio overclocking really is a pointless endeavor on the 3900X. I guess pushing things too much is an asus thing. Check your voltage if you run high temps on idle!!! 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 Voltage offset is your friend. The starred/preferred ccx were my weakest, smh. I changed RAM timings to 16-16-16-32 and still got horrible performance. It maybe just one limiting core or CCD. unfortunately the manual is useless. The best I could do was 4.35 GHz on the good chiplet and 4.25 GHz on the bad chiplet. 8028 on the Cina - not to bad, Ran AVX2 Beta in CPUz as a stress, seems good for about an hour. The heat and voltage required is too high. 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 think i looked in every menu and submenu. JavaScript is disabled. for example, there are 2 VDDGs in the bios, and neither of them are labelled CLDO. 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 might try some chilled loop OC'ing a later this year. Sure 50-60 idle is kinda too much, but then it shouldn't stay at 4.2GHz while idling as well. it doesnt explain any of this... i looked. thanks again for the input. Again, im not shooting for the stars but id also like things to be correct. 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. 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 feel a little stupid now. Then they run hot. I found it to be completely wrong. 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). I wrote a massive reply but decided to deleted it. Setting the Bar for High Performance. I am running the latest ABBA bios for the MEG Ace. Oic it is in "red" now. Memory rank? I guess I though Ryzen Master was taking care of this, but I guess not, because I got further. Ryzen 9; 3900x heat, voltage and frequency issues. The Ryzen 9 3900XT, 7 3800XT and 5 3600XT processors have 12, eight and six cores, respectively. So I had a look in bios again. Maybe with a better RAD or something I could do better. Pushed the voltage up incrementally to 1.35 to see if I could push 4.5GHz on all cores. You are close to that 8K geeze! Thanks for the info and your time. I am talking identical setup other than the CPU 3600 vs 3900x in the Asus setup. My board was over-volting my 3900x by quite a bit. 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. 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. AMD specifies 3200MHz as memory clock on the Ryzen 9 3900X. I am not sure that I am doing it right... but its working ok so far. You're supposed to watch temps under heavy load, not while idling. On asrock idle voltages are miles better than asus in windows. Low 50s on idle. Memory type? 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. The onboard firmware in the CPU controls that, not the power plan. Maybe I'll make it 16-16-16-32. Jul 12, 2019 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. jayztwocents mentioned this. I tried some overclocking with Ryzen Master. So, I went back in and removed the -.1 offset from core voltage. 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. So I am very confused in terms of a "Safe" all core voltage for my 3900x. PCB revision? Yeah, I was going to say.. thermally limited, 1.5v too much. Anything higher will not finish a CB20 run. Anyone using a 3900x with a corsair h110i gt? It doesnt explain them at all. If LLC is set too high, this spike in voltage as the CPU goes to idle could be reaching harmful levels. Now, I can get the sh!tlet to 4.3 and the chiplet to 4.425 and pass Cinebench. Quick Side Note : All of my overclocking is done in the BIOS, I really do not like the Ryzen overclocking tools. Chip still wouldnt get stable over 4.6 with 1.4+ volts. 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 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? ... which should be enough to ensure that the system won’t crash and that temperatures won’t get too high. I jotted down some numbers from a thread on techpowerup and a video by jayztwocents (YouTube). I’d keep it in the 1.3x v range.
