Do you still run these settings? I got my 5900x a year ago this month and had a lot of trouble over/underclocking when I first got it. I updated my BIOS today so I’m redoing the undervolt and I’m about to finish my first test with all -30 (no errors). I have a hard time believing I’ll be stable all of a sudden, but am curious to hear your experience?

i recommend using small dataset with extreme mode on instruction set SSE when testing individual core, this will strain undervolting more. i noticed for example that my c1 would fail on first run as it swapped from c0 to c1 but often be stable after, this kind of indicates just because you pass most of the times does not necessarily mean it is stable. I had same issue with c2, where it sometimes fail when it previously passed (on -15). in the end i had c4-c11 at -30, c3 at -20, c0 at -17, c1 at -7, c2 at -12. when testing to get a setup for a longer test i ran 2 minutes per core at small + sse. after finding what appeared stable i ran 2h all core large+avx2, each core for 20minutes at small+sse, then all cores at 1h at small+sse. this allowed me to get full stability. previously i had been running all cores set to -10 and while it was stable 95% of the time i occasionally had issues, which as previously mentioned was due to c1 not being 100% stable there. by setting per core curve i ended up with better performance overall since most cores are at -30 and stable, and no crashes at all since i identified c1 as my problematic little black sheep. fastest way to reach your stress test limits i think is to start with all cores at -30 and then test one at a time for 2 min, check which fails and which passes and continue from there. when it comes to how much you drop it by you can go by how fast a core fail. if its instant you might as well drop by -10 straight away, if it lasts for like 1min before issues you can go for a -5 drop to begin with. this let me quite quickly find my settings for extended benchmarking. temps overall dropped, most notably during low loads (webbrowsing etc) and a bit less drastically during high cpu load stuff. overall wattage didnt drop all too much on the cpu, the gpu underclocking though (3080) brought me from 340w load to 270w load while also overclocking the memory.

on my 5800x I have a 1.2 core voltage max with a 4.6 core clock and 100mhz boost with PBO disabled in bios completed the 15 minutes stress test on extreme twice in a row and hit a maximum of 66c averaged 60c all cores at 4600mhz. Whereas in PBO curve Optimizer I had all cores negative 30 except my 7th core that had be brought down to -15 and then it passed the OCCT test twice with a max temp of 77c and an average of 74c some cores hitting a max of 4.790mhz most staying at 4.680/4.700.. long story short I reverted back to my manual undervolt/overclock.

1. Disable global c-states in the BIOS (allows for more undervolting than having them enabled) 2. Use Ryzen Master to auto-optimize some curve optimizer values; these will get you in the ballpark. Use PBO2Tuner to set them - no need for the BIOS, yet. 3. Use Core Cycler (ycruncher Kagari and Prime95 Huge) overnight - these are the low-load, high-frequency scenarios that best expose CO instability. If a core/s fail, use PBO2Tuner to increment, then test again. I'm in the middle of testing at the moment, but Ryzen Master gave me -28,-30,-30,-30,-30,-30, while Core Cycler testing has shaved it down to -21,-21,-29,-27,-25,-26; still testing the fifth core.

Hello there. Good video but I have one big complain about the way you test with OCCT. I decided to try your method and believe it or not I succssed to pass the test for 1 hour with setting each core at - 40 OC on 5900x. This is basically impossible even with the best silicone. Then I decided to test each core separately so it can boost to its max frequency and voltage and my core 0 fails instanteniously. The thing is voltage doesn't rise proportional with frequency. Testing for stability all cores together drops the voltage to about 1.2 to 1.25v but testing each core separately increases the voltage of that specific core above 1.3 v. So what I found for the best method is this. Do OCCT on each core separately for 15 mins changing OC. Once every core pass the test run OOCT in the way described in the video but for 1 hour. If pass the test next is Cinebench 23. Run loop for 1 hour on single and multi core. If no crashes or errors the last step is back in bios and decrease OC by 2 (for example if it was -20 do it -18) on each core. Congrats you have 99% stable system for 24 hours use. PS: Don't use Prime95. This imo is the world's best useless program ever created.

I just want to throw this out there that undervolting your cores then passing benchmarks/stress-tests doesn't guarantee stability. I tried undervolting my 5800x and passed all sorts of these benchmarks and stress tests like OCCT, cinebench, and Prime95. I noticed my computer would start randomly rebooting itself whether it'd be from doing lightweight-tasks like watching Netflix in a web browser or playing Skyrim Special Edition. I then turned off all of those curve optimizer settings that undervolted my CPU and just tried the built-in "ECO mode" to undervolt and underclock the processor, and that only made the random reboots more frequent. Perhaps I got unlucky with the silicon lottery, but just know that you're still taking a risk using an undervolted processor even after passing all sorts of tests to try and verify stability. To clarify, I did extensive testing on my storage devices and memory which all came back without problems, and I'm pretty confident the random reboots were the result of undervolting especially since reverting all curve optimizer settings to default made the random reboots stop.
@TooBokoo

Truthfully, unless you run, like 20 hours straight of something like CoreCycler, you'll never know for sure how stable your machine is. However, running stress tests can, at least, give you a rough idea on stability. If a stress test fails, at least you know something is wrong right away. For me, it's usually just a week or so long experiment of using my PC. Once I undervolt, I spend the week playing games, watching KZitem, surfing the internet, listening to music and running all sorts of my day-to-day programs. If I don't crash after a week, I feel pretty ok. If I crash, I dial things back a bit and try again. Overclocking and undervolting has always been a series of trial and error.

There's a much better way to test this. - Select Advanced under 'Threads', then click on Advanced Thread Settings. - Select only one Physical Core and test it for 1 minute. - If it errors or not, make a note then change to another Core. - Repeat until all cores have been tested. - Adjust all errored cores down by 5 until you reach 20, then 2 after that in Bios. - Repeat the above until you get no errors. - Do an all core test for 1 hour. This is much faster and more accurate this way, and because it's a single-core test, it actually stresses that core more than a multicore test would. It also allows you to monitor the single-core boost frequency of each core. Better cores will clock themselves higher.

I do see though i'm only really boosting to 4600mhz, to be fair it'll sit their all day even when under a heavy gaming load, realistically how much performance could be expected from a 5900x?

I'm either really unlucky with my 5900x chip, or there's something else at play here. Kept dropping all-cores negative value in increments of 5, up to .... 5. Which made the system reboot after half an hour of benchmarking. Eventually gave up and returned it to stock - it's just not happening on my chip.

Can you do this on Ryzen Master first before applying it on the BIOS? I think it's better to do it in ryzen master first so that you don't need to enter the bios every time there's an error, you'll just apply it on bios if you already found the stable undervolt for each of your cores.

If I disable it, the Auto Core Frequency is set to 3700 and it wont get up, if I set it to let say 4300, it wont slow down - which is I assume the work of CPB - do you have any suggestions for that? or am I stuck with faulty CPU or old MB?

All 12 cores are visible and functioning now. Weirdest damn thing I ever saw with a CPU. I am now successfully undervolted, and I dropped my max temps by 15c and gained 2k points on Cinebench R23 (hitting 21,388 now). Just had to go through a lot of hoopla to get there. P.S. I still didn't win the silicon lotto though. I did a per core undervolt and I am only able to run my best cores at -17 and the worst (3 of them) at -13, and that is also with changing PBO limits to motherboard controlled vs auto. Anything else and it would still crash the system. I'm using a Corsair H100i 280mm AIO and have 7 system fans pulling in from the front/top exiting the rear, so cooling shouldn't be an issue.
