  1. the only thing that worries me is a Ryzen 7 on a budget-oriented b350 board. I wouldn't recommend taking the vcore higher than 1.35v.
  2. Try 2 hours. 5-30 minutes is useless. I'm not satisfied until I can let my CPU overclock run overnight (7hrs) without it failing. When you use Aida64's stress test. Check only the first three boxes. CPU / FPU / Cache.
  3. My concern and reason for lowering the frequency is the fact that I have the same Ryzen 5 1600, but I'm unable to do 3.9 at lower than 1.4v. I don't know how you tested stability, but if you can run aida64's system stability test stressing CPU/FPU/Cache for at least 1 to 2 hours without it failing, then you've got a damn nice lottery ticket in that CPU. Perhaps you're using some LLC methods to enable a lower voltage, my crap board doesn't have that option.
  4. As a test, re-enable SMT and lower the frequency to 3.7. See if all 6 cores / 12 threads show up. Leave the CPU Core Voltage at 1.35v It might be better just to reset your CMOS, I've no idea what you may have changed that may be causing problems. Just change the frequency to 3700 and vcore to 1.35
  5. @MageTank Not to hijack someone's thread, but it's sorta on topic. What's your opinion on Ryzen system calculator v 0.9.5 + Records? I saved that to my Google Drive and used it on my 3000MHz Hynix M-Die kit. Instead of tightening the usual CL, tRCD, tRP, tRAS, tRC.. I've begun experimenting with the tRFC Calculator (tab at bottom) and lowering those numbers while leaving my primary timings at default. Is this what you're referring to above when you mention tighter secondary and tertiary timings? Edit: I just went back and looked at your guide again, perhaps I should pay closer attention to what I read.
  6. This seems true for all but the 1600. It's noted in my list above, some only have a 50 xfr boost. I've also not bothered with P-States yet as I've pretty much given up on my ASSrock board being able to push any frequency worth having. The lack of LLC options has seen me settle for a manual 3.8GHz overclock.
  7. Ryzen 1400 OC Help

    Download the trial version of Aida64 and use the System Stability Test to stress CPU / FPU / Cache. If your 3.6GHz overclock is stable at 1.26v, then you should be able to run that stress test for at least 1-2 hours without it failing. Personally, I'm not satisfied with my CPU overclock until I can run Aida64 overnight (7hrs) without it failing. I agree with Squinty, though, your stock cooler can probably handle 3.7 or 3.8 at around 1.30-1.35v. As long as your CPU Package temperature doesn't go beyond 80c, you're fine.
  8. Mine's not default.. I think the min is 90% though. Kinda makes me wonder when and why I changed that.
  9. I should probably make a note in my original post about using AMD's Ryzen Balanced Power Plan. I'm not sure what plan you're using, but if you've overclocked your 1700x to 3.8, it should stay at 3.8 unless you're using Windows' default Balanced Power Plan which underclocks/undervolts your processor when idle, which it does if you have C-State enabled in the bios (default). At least I think that's how it works. Supposedly boards are supposed to automatically disable Precision Boost/XFR when a manual overclock is applied.
  10. At idle, and stock, does your frequency sit at base clock 3.4GHz, or does it boost all cores to something higher?
  11. http://www.guru3d.com/articles-pages/amd-ryzen-threadripper-1950x-review,2.html According to that site, and the screenshot at the bottom, you're correct. TR does boost four cores.
  12. yep It may, I just threw Threadripper in there because the numbers were the same. The list is a work in progress.
  13. There are many opinions on how AMD's Precision Boost and Extended Frequency Range (XFR) work. Several sites on the web have wrong, or perhaps old, leaked information. I'm actually guilty of giving false information based on what I read on the web. From what I can determine, it's explained correctly here. https://www.pcper.com/news/Processors/PSA-AMD-XFR-Enabled-All-Ryzen-CPUs-X-SKUs-Have-Wider-Range Basically, for a Ryzen 5 1600 with a base clock of 3.2GHz. At default bios settings, Precision Boost, with the help of AMD's SenseMI Technology, will automatically overclock all cores to 3.4GHz in increments of 25MHz. If core temperatures are still within safe ranges, two cores will continue to increase in 25MHz increments up to the reported Boost Clock of 3.6GHz. XFR will then increase these two cores an additional 100MHz, if thermals permit, to 3.7GHz. I never actually see these increments, though. HWMonitor shows my six cores alternating between four at 3400 and two at 3700. Precision Boost and XFR can be disabled in the bios via the advanced Core Performance Boost option. I've begun compiling a list of Ryzen and Threadripper Base and Precision Boost clocks with XFR. If anyone can verify these numbers, or fill in missing numbers, I'd be grateful and will use that to update this list. Base Clock Boost (all cores) Boost (two cores) XFR (two cores) XFR Limit Ryzen 3 1200 3.1 3.4 3.45 50 Ryzen 3 1300x 3.5 3.7 3.9 200 Ryzen 5 1400 3.2 3.4 3.45 50 Ryzen 5 1500x 3.5 3.6 3.7 3.9 200 Ryzen 5 1600 3.2 3.4 3.6 3.7 100 Ryzen 5 1600x 3.6 3.7 4.0 4.1 100 Ryzen 7 1700 3.0 3.2 3.7 3.75 50 Ryzen 7 1700x 3.4 3.5 3.8 3.9 100 Ryzen 7 1800x 3.6 3.7 4.0 4.1 100 TR 1900x 3.8 4.0 (four cores) 4.2 (four cores) 200 TR 1920x 3.5 4.0 (four cores) 4.2 (four cores) 200 TR 1950x 3.4 3.7 4.0 (four cores) 4.2 (four cores) 200
  14. With all Auto settings, bios defaults. I disabled Core Performance Boost and my CPU frequency is locked at 3.2. No Precision Boost, no XFR. I thought Core Performance Boost = XFR. I guess it's both.
  15. I have unexpected results doing that. I removed my overclock. At stock my 3.2GHz Ryzen 5 will clock all cores to 3.4, 3.6 boost, 3.7 xfr. Running the single core Cinebench (scored 136) didn't actually use a single core. It seemed to spread the workload over all cores. I also noticed my Precision Boost doesn't even bother with 3.6 at all and jumps straight to XFR's 3.7GHz (but on two cores). I'm confused now. I thought XFR only boosted one core higher than Precision Boost and only if the other cores were idle. For the record, I use the Ryzen Balanced Power Plan. Edit: Same score when manually overclocked to 3.4.
