    any PSA on what manufacturers fixed voltages or ones that refuse too? love to know why it was so jacked in the first place.
    also that shirt just got alot more relevant or atleast half right.

      Interestingly my 3700x tanks in performance when put the voltage to 1.35. but I found out that if I use windows balanced mode I got idle voltages of around 1.2.
      Even more interestingly is that it looks like that the 1.4 to 1.5V is intended to boost single core performance but it goes down to 1.1V if you use more than one thread, probably for thermal limits.
      Going from ryzen balanced mode to windows balanced mode also reduced temps by over 10C. Idle is now 40 to 50C ish gaming and testing is 60 to 70C isch.
      Activating precision boost overdrive is also a killer as the 3700x can draw up to 130W instead of 88W. Tho that doesn't come into play during gaming as the cpu probably doesn't need an all core boost. Nevertheless I reduced the max power draw to 100W that is a good balance between temps and performance in multi threaded loads. If I render something I can still boost it back up to 130W.

        Glad I watched your video. My asus x570 and this was after I downloaded the latest bios from the internet feature. My cpu voltage was 1.4x. Lucky only ran it for a day like that till I caught it. Thanks!

          I'll definitely be referencing this video to overclock my 3900x, and maybe I'll update this with temps because I'm doing air cooling on the beefy noctua NHD--15

            Please include Rainbow Six Siege in gaming benchmarks since it's heavily CPU bound, and uses all cores.

              I get massive drops in cinebench r20 multithreaded score (from 4600 to around 4000) if I drop the voltage (by 0,15v offset) even at same Mhz value on my 3700x. It's really weird. It's like it disregards the manual bios settings altogether (and auto-adjusts to keep stability maybe?). I'm on an ASUS ROG Strix B350-F gaming mobo btw.

                Tbh thisd is great info but it doesnt tell us whether we should oc for games since you only tested one. We'd need 10 games oc vs not oc (just xmp + fclk)

                  I've done everything and my performance (vcore to 1.3 from auto) is a lot lower than before :D

                    It would be fine showing the OC process and BIOS values. Just show the benchmark results is not your style...

                        Yep, its true the overclocking on the new 3000 series amd's isn't all that great. There just isn't that much headroom it seems. But is that a bad thing? What that tells me is they are running these things at the best performance they feel they can safely run them at right out of the box. They are not crippling them and underclocking them so they run cooler or so they can release an "overclocked" or "unlocked" version later and charge more money for it because its "special". Instead you buy your cpu for 200 to 400 dollars or so, plug it in and it runs about as good as it can. You don't have to spend a bunch of time tweaking and messing with it. As a general consumer I think this a great thing. You are actually getting what you are paying for.


                        It is sort of like buying a newer car. They spend a lot of time and money to make these things run the best they can. I mean we are getting 200 horsepower out of small 4 cylinder engines these days. And getting 30 plus miles to the gallon out of them. If you think throwing a 200 dollar cold air intake and a new muffler on it is going to make it go faster you are probably wrong. Chances are those new "performance" parts are not any better than what the engineers designed at the factory.

                              1.47V is normal.

                              The stock voltage parameters are, 1.325V max for all core workloads, and 1.47V max for single core workloads.

                              The stock memory and SoC voltages are not however.
                              Also, DOCP is Asus' term for XMP, and the SoC voltage is also for the IMC. Basically VCCIO and VCCSA on Intel, are VSoC on Zen.

                                Something or other is goofy about this series though. I recently purchased a 3600 and on the stock cooler it idles at 55-60c (it hops all over the place no matter if its ryzen balanced or windows balanced power plan) and hits 90 under a cinebench load and if i try to run two back to back I get thermal shutdown at 95. Ive reseated the cooler a few times, and despite the 60 idle, the cooler is not warm at all. So i dont know if there's an issue with the core to ihs transfer or IHS to heatsink, but something is goofy.

                              Hero. Just built a new rig with a 3800x and after boot was woundering why it was idle at 60c. Lowered the volts and benchmarked Hitman 2 and hit a peak of 55c under load.

                                      Should we never go above 3600 MHz on ram with any ryzen could then?

                                        Thanks J, I have the same board and felt like the setting were off but wasn't sure how to fine tune it or even what to look at!! No wonder my 3600x on idle was running so hot.

                                                I was really hoping Ryzen would hit 5ghz this time. People will still buy intel because it can't. Even if AMD at lower frequency is still faster.

                                                          Hmm okay I was afraid I was the only one with ~40°c cpu on idle, this calms me a bit.

                                                          Will the voltage be changed with patches or something that has to be done manually?

                                                              I wonder if leaving things on auto OC and trying to decrease voltage a little would net in an actual higher boost


                                                              secondly, what the difference between 3600 CL16 and 3600 CL14 with as tight timings as possible are


                                                              And lastly, if Water chillers have an actual use now, with Ryzen 3000 doing higher clocks with every few degrees less :-)




                                                              Btw, no individual core OC (or rather individual CCX), like you could do, in theory, with Intel?

                                                                                  so lets say I have 3200Mhz memory and the infnite fabric is set to Auto or value such as 1200, 1500
                                                                                  all I need to do is set XMP and infinite fabric 1:1 with my memory so 3200Mhz=>means 1600

                                                                                  • ReLoadXxXxX

I also don't know when your saying "your not going to see 4.6.." if you mean on average or max. Would be nice to see more of what your doing, your core clocks, temperatures and less face-time blabbering on - no offense.
