@gupsterg god damn this 2701 bios is GREAT once you get around bugs windows drivers ect. I noticed that after some time today it does not double boot for whatever reason oO then i did cmos clear and started again WEIRD.
Anyway check this out i got memory voltage down to 1.4 passed 600% last night forgot to take screenshot lol So did another 1.5 hour or so run. with EVEN TIGHTER tier2 and tier 3 timings. As always my Teamgroup kit does not want to work with cl14 i tried up to 1.55 errors instant errors. But do I need cl14 when I'm on sub 63ns with read write and copy at those raltes ?? 😄

I think due to the buried nature of Global C-State Control I think people are mistaking PSS Support as that. Dunno though, all I'm seeing from things I've looked at, that PSS is a ACPI spec and not an AMD thing.

PSS Support = Processor Supported States Support [Auto/Enabled/Disabled]

Thanks for the Linux link. I was wondering what the deal was with low clock readings.

I hope the next BIOS will be able to boot recent versions of Linux. The current one, 2501, cannot due so due to the AMD RDRAND bug when using Ryzen 3000s. Does anyone have an estimate on when a fix will be released?

Thanks!

Not fixed in the latest C7H on Asus' site: https://www.asus.com/Motherboards/ROG-CROSSHAIR-VII-HERO/HelpDesk_BIOS/
They have not rolled in AMD's fix yet.

Should I be afraid?

Any bugs found with this one yet?

Under 2606:
Well, memory integrity protection no longer works work me under Windows 10 core isolation. When enabled, Windows blue screens on startup with a system_thread_exception_not_handled. On the next boot, memory integrity protection is disabled.

Some versions of Linux don't boot still due to RDRAND error as we know as this is not fixed in this version.

Under 2701:
Same issue with Windows. Linux will boot further due to RDRAND error being solved. But under some versions of Linux I receive an sev command timeout error. Seems the new AGESA code is causing problems with SEV. :eek:

Looks like 2501 continues to be the best option, sans some linux distros, as well as the similar 5007 on my other X470 board. Will be interesting to see how long it takes for AMD to beat their own AGESA.

Yup. Looks like this might be related to SME not SEV.

AMD over the weekend updated the product-pages of its Ryzen processors on the company website to be very specific about what they mean by "Max Boost Clocks," that are advertised almost as extensively as the processor's main nominal clock-speeds. AMD describes it has "the maximum single-core frequency at which the processor is capable of operating under nominal conditions." We read into this as the highest boost-clock given to one of the cores on the processor.

If you've been reading the "clock-frequency and boost analysis" charts in our processor reviews, you'll know that AMD processors spread their boost frequency progressively across cores during a multi-threaded workload that scales across all cores. At any given time, only one of the cores is awarded the highest boost clock, and while the other cores too get boosted beyond the nominal clock-speeds, they are in slight decrements of 25-50 MHz. The graph below is from our Ryzen 7 3700X review. The second graph below is from our Core i9-9900K review, which too shows only one of the cores getting the max boost frequency, and the remaining cores getting lower boost clocks, although the graph looks flatter.
