    So I did a search on "ASUS" on C:\ having uninstalled every single ASUS installation, and I deleted all the file folders left behind (why didn't it delete those?!). I still had hundreds of results and the ASUS services were still listed in Services, although of course they were not started. I just thought how ridiculous it was that it hangs around like a virus, so I did a Windows 'refresh' reset. The first thing I did upon getting into Windows was downloading PT 10.

    I'm pleased to report my scores are back exactly where they should be. Phew Floating point math is up 6600, and single core performance up 450. Now my floating point math in particular is one of the highest scores on the chart.

    I still think it would be good to hear what ASUS have to say about this. I disabled 'Install Armoury Crate' in the BIOS before my Windows refresh and that led to absolutely no trace of any ASUS software upon starting Windows.

    Do you think it's safe to install the AMD Chipset Drivers? I have avoided Gigabyte's XTREME Gaming Engine for GPU overclocking as I think I read this could cause issues, and instead I'm using NVIDIA Inspector (an open source program with absolutely zero bloat!). My CPU test scores remain good.

      Comparison of floating point math with ASUS software installed (image 1), and not. Interestingly there is a different shape to the curve as the different threads load up. Maybe this means something.

        ASUS replied that they are looking into it. If we hear anything I'll let you know.

          ASUS claim they are not able to reproduce the issue as would like like to know the motherboard model and BIOS version(s) you are using.


          • #20
            The motherboard is the ROG Strix X570-I Gaming

            BIOS is version 3406, but I had the same issue on 3001.

              Another question from ASUS. Where did you get the AI Suite 3 software from. (CD in the motherboard box, ASUS web site, somewhere else?)
              It is a bit of a strange question, as the version number should identify the install package well enough. Unless they thought that some packages are corrupt, infected, or their version control is poor.

                That is a bit of a strange question.

                In the ASUS Armoury Crate software, it was listed as one of the downloads under 'utilities' and so it downloaded and installed it via the ASUS platform itself.

                  I want to report that I had the same issue and was able to resolve it!

                  I did two things:
                  1) [This is probably not necessary] I followed the instructions at the bottom here. Specifically, I ran this command: "bcdedit /deletevalue useplatformclock". This helped with the floating point benchmark, but not so much with the single CPU benchmark.
                  2) [This step is probably sufficient] As discussed in this thread, I did a "Windows 10 in-place upgrade".

                  My scores, which used to be high:
                  Went to fairly low values after install AI Suite 3:
                  After doing the above two steps, my scores are actually now higher than the first baseline, which is expected since I upgraded RAM. Unfortunately, I cannot resubmit the baseline now that the issue is resolved.

                  What more: the in-place upgrade kept all my applications. I'm still testing things, but as far as I can tell it didn't break any of the application installs.

                    UPDATE 1/March/2021:
                    We have been in discussion with ASUS about the issue.

                    After testing they confirmed a bug in their AI Suite 3 software related to the HPET (High Precision Event Timer) clock.
                    They are saying it will be fixed in a "future" release, but at the moment they can't tell us when this will happen or the version number of the new release. They also didn't describe the exact nature of the problem. Not sure why all these big companies need to be so secretive, sigh.

                    This HPET issue has been a very long running issue for Ryzen CPUs. Here is a copy of what I wrote 4 years ago below.
                    If you do a Google search there are 100s of pages discussing this HPET issue.

                    AMD is giving out conflicting information. They are saying HPET should be off for performance reasons, but they are also saying it should be on when using the AMD Ryzen Master application which is used for overclocking to increase the performance. Which of course makes no sense.

                    The way of measuring time on a PC has changed over the years. From oldest to newest the various hardware is,
                    RTC, Real Time Clock
                    PIT, Programmable Interval Time
                    PMT, Power Management Timer
                    HPET, High Precision Event Timer
                    TSC, Time Stamp Counter [and there are two versions of this, Invariant TSC, (ITSC), and original flavour TSC]

                    You can tell the frequency of the clock (and this which one is in use) by using the Windows QueryPerformanceFrequency() call,

                    Anyway all new systems should be using the TSC. So even if the HPET is enabled in BIOS, it shouldn't be used. So from that point of view it makes sense to turn it off.
                    BUT the instructions from AMD for using the AMD Ryzen Master application tell you to turn it on in BIOS, then reconfigure Windows to use it. Why I don't know, as this make little sense.

                    Here is what I suspect is happening. When you overclock Ryzen inside of the O/S then the TSC clock also get effected (sounds like a bug in the CPU to me, but anyway). Meaning the clock is no longer accurate and benchmark frame rates won't be accurate either. So to avoid this problem AMD suggests you force the use of HPET when overclocking inside of the O/S. The HPET timer remains accurate regardless of CPU clock speeds. This isn't a problem I suspect if you overclock from BIOS.

                    An inaccurate clock might also cause the video stuttering you saw.

                    So by forcing HPET to be on you get an accurate clock back, but there is extra interrupt processing overhead required when you are using HPET.
                    But if you aren't overclocking then you can leave HPET off I would think.

                    It is a complex mess of inaccurate & partial information. So maybe AI Suite 3 was forcing HPET to be turned on and even if you uninstall it, HPET remains turned on.

                      Interesting stuff. I did come across HPET in some forum threads before I did my reinstall but had no idea how to change it because I didn't have a BIOS setting for it.

                      At least now we know for sure what it is and how to avoid it and fix it if necessary (reinstall Windows).

                      I'm glad ASUS have admitted the bug, and as for when they will fix it, I shall be steering clear of AI Suite for all eternity!

                        You don't need to reinstall Windows. Do Windows in-place upgrade.

                          MY RYZEN 5950X IS CRIPPLED BY THIS ALSO

                          I just recently tried out Passmark for the first time yesterday and was shocked to find my 5950X scores were WAY below what other users were getting. I am only getting one THIRD of the floating point performance according to these results. Is it that the results are not reporting correctly or I AM actually getting 1/3 performance overall in floating point in all applications now???

                          If it is the case that I am only getting 1/3 performance in this critical CPU operation (critical for all rendering work) then that could be grounds for legal class action lawsuit against ASUS for gross negligence and damages.

                          I seem to have latest version of this AI Suite installed ie. this:

                          Version 3.00.69
                          2020/10/28 165.61 MBytes
                          ASUS AI Suite 3 V3.00.69 Install Program for Windows 10 64-bit.
                          ASUS Dual Intelligent Processors 5 V2.00.54 for Windows 10 64-bit.
                          ASUS EZ Update V3.00.13 for Windows 10 64-bit.
                          ASUS System Information V2.00.09 for Windows 10 64-bit.

                          How can I fix this?? There is NO WAY I and not a chance I would go to the monumental effort of reinstalling Windows and hundreds of apps and configuration for this.
